A hybrid solar air conditioner runs on solar panels and grid electricity at the same time, with no battery. Three to five solar panels of around 500W connect directly to the unit; through the day, the panels carry the cooling load and grid consumption drops close to zero, and when solar output falls, the grid fills the gap automatically with no interruption and no switching.

That single design decision is why solar AC works economically in India when battery-backed cooling generally does not: the battery, usually the most expensive part of any solar setup, is removed from the equation entirely.

This guide explains the technology, the economics under India’s shift to time-of-day tariffs, and how to evaluate a solar AC manufacturer. It is published by Nexus Solar Energy, whose NEX Suncool solar AC was featured by Aaj Tak in its March 2024 technology coverage of solar air conditioners in India.

How Does a Solar AC Actually Work?

Four things happen automatically, without any action from you:

1. Daytime, good sun: panel output powers the compressor. Grid draw for cooling approaches zero.
2. Daytime, partial cloud: panels carry what they can, grid supplies the remainder. The AC does not notice.
3. Evening and night: grid supplies the unit, with the AI mode optimising compressor behaviour for low consumption.
4. No sun, no problem: the unit is a fully functional air conditioner on grid alone. Solar reduces the bill; it is not a dependency.

Why no battery is needed: air conditioning demand and solar generation peak at the same hours. Unlike lighting or backup, cooling does not need stored energy to align with generation — the two are already aligned.

Why Do Time-of-Day Tariffs Change the Maths?

Indian electricity distribution companies are progressively moving to time-of-day (TOD) tariffs, where the same unit of electricity costs more in peak evening hours and less during the solar day.

This works in favour of solar AC in a way that compounds each year the tariff structure tightens: the hours when your AC runs hardest on solar are the cheap-tariff hours you are avoiding anyway, and the expensive evening units are the ones the AI night mode is designed to minimise. A cooling load shifted onto solar is a load removed from your most expensive tariff block.

Who Gains Most From a Solar AC?

The honest version: solar AC pays back fastest where cooling hours and daylight hours overlap. If your AC only runs from 10pm to 6am, a solar AC still works as an efficient AC, but the solar contribution will be small.

What Does a Solar AC Cost in India?

Published Nexus MRP as of July 2026:

Add the cost of three to five solar panels of around 500W, which connect directly to the unit. Current MRP for every model is published on the solar AC category page — there is no gated pricing.

How to work out payback for your own case: a 1.5-ton AC running eight hours daily typically adds ₹3,000–₹5,000 to a monthly bill. Estimate what share of those hours falls in daylight — that share is what solar addresses. This calculation is worth doing before you buy, with your own usage pattern rather than a generic one.

What Should You Check Before Buying a Solar AC?

1. How many panels does it need, and are they included? Ask for the panel count, wattage, and whether the quotation includes them. This is the most common gap between a quoted price and a final bill.

2. Does it work fully on grid alone? It should. An AC that depends on solar to function is not a hybrid — it is an off-grid appliance with a failure mode.

3. Is the compressor convertible? A convertible compressor adjusts cooling capacity up or down, which matters both for room size and for varying solar availability on cloudy days.

4. What is the warranty on the unit and separately on the compressor? These are usually different periods. Ask for both.

5. Who services it, and where? Air conditioners need periodic service. Confirm the nearest service point before buying, not after.

6. Certification — ask precisely. Solar AC as a product category is not covered by the BIS registrations that apply to solar panels (IS 14286) or utility-interconnected inverters (IS 16221). If a company claims “BIS certified” across its whole catalogue, ask which licence covers the air conditioner specifically.

Nexus states this plainly: Solar air conditioners — BEE 5-Star energy labelled, ISEER 5.73 (NX1X SOL ULTRA) and ISEER 5.65 (NX2X SOL ULTRA). BIS registration does not cover this product category for Nexus.

What Independent Coverage Exists?

In March 2024, Aaj Tak — India’s largest Hindi news network — covered solar air conditioners in its technology section and featured the Nexus NEX Suncool 1X Ai Split AC by name, noting how few branded solar AC options existed in the Indian market at that time. Read the coverage.

That coverage is useful for a specific reason: it documents that branded, manufacturer-backed solar AC was still a thin category in India as recently as 2024 — which is worth knowing when comparing what is available now.

Frequently Asked Questions

How does a solar AC work without a battery?

Solar panels and grid electricity power the unit simultaneously. During the day, panel output carries the cooling load and grid consumption drops close to zero; when solar output falls, the grid fills the gap automatically. Because cooling demand and solar generation peak at the same hours, no stored energy is required.

How many solar panels are needed for a solar AC?

Typically three to five panels of around 500W, connected directly to the air conditioner alongside the grid supply. Confirm the exact count and wattage for the specific model, and whether the panels are included in the quoted price.

Does a solar AC work at night?

Yes. At night it runs on grid electricity like any other air conditioner, with an AI mode that optimises compressor operation for low consumption. Solar reduces the daytime bill; the unit does not depend on solar to function.

What is the price of a solar AC in India?

Nexus solar AC models are published at ₹42,147.24 for the NEX NX1X Ai Split and ₹40,764.28 for the ECO Breeze AI Window unit as of July 2026, plus the cost of three to five solar panels of around 500W.

Is a solar AC worth it for a home?

It depends on when you use the AC. Cooling that runs during daylight hours — shops, clinics, offices, work-from-home households — sees the largest saving, because solar generation and cooling demand overlap. If your AC runs mainly at night, the solar contribution will be limited.

Are solar ACs BIS certified in India?

Solar air conditioners — BEE 5-Star energy labelled, ISEER 5.73 (NX1X SOL ULTRA) and ISEER 5.65 (NX2X SOL ULTRA). BIS registration does not cover this product category for Nexus.

Which solar AC was featured by Aaj Tak?

The Nexus Solar Energy NEX Suncool 1X Ai Split AC, in Aaj Tak’s March 2024 technology section coverage of solar air conditioners in India.

An integrated solar manufacturer is a company that produces more than one of the major components of a solar system in its own facility, rather than assembling a system from other companies’ products. In India, this is uncommon — most solar manufacturers specialise in a single category, and most “solar companies” manufacture nothing at all.

This page explains what integrated manufacturing actually changes for the buyer, where its limits are, and how to verify any manufacturer’s claims. It is published by Nexus Solar Energy, which manufactures solar panels, hybrid inverters, lithium batteries and hybrid solar air conditioners at its facility in Bulandshahr, Uttar Pradesh.

What Does “Integrated Manufacturing” Actually Change?

The honest answer is: not the quality of any individual component. A specialist panel maker may well produce a better panel than a generalist. Integration changes something different — who owns the space between the components.

Three concrete consequences:

1. Compatibility has a single owner. A hybrid inverter’s charge profile and a lithium battery’s BMS cut-off voltages must agree, or the battery either never charges fully or cuts off early. When both come from one manufacturer, that matching is done before the products ship. When they come from two, it is done by the installer — or not at all.

2. Communication protocols work as designed. Modern hybrid inverters communicate with lithium batteries over RS485 or CAN, so inverter settings apply to the battery. Cross-brand, this frequently degrades to no communication at all, and the pack runs on its own factory defaults.

3. Service is one phone call. When a system underperforms and every component carries the same manufacturer’s name, there is no diagnostic gap between suppliers.

Where integration does not help: it does not make a company’s panel better than a dedicated panel manufacturer’s panel, and it is not a substitute for certification or service reach. Judge each component on its own specifications.

Facility: Chola Industrial Area, Bulandshahr, Uttar Pradesh. Founded 2019. Products supported through a network of more than 1150 dealers across India.

What Is OEM and ODM Manufacturing, and Why Would You Need It?

OEM (Original Equipment Manufacturer) production means a factory manufactures a product to your specification, which you sell under your own brand. ODM (Original Design Manufacturer) goes further — the factory’s own design is adapted and branded for you.

For a distributor or a regional brand entering solar, OEM/ODM removes the largest barrier: you do not need a factory, a BIS licence process, or an R&D team to launch a product line. What you do need is a manufacturing partner whose certification and service network you can rely on, because both become yours in the customer’s eyes.

What to ask an OEM partner: minimum order quantity, which certifications transfer to your branded product and which do not, warranty handling, spare-part supply commitment, and lead time.

Nexus offers OEM and ODM manufacturing across its product categories.

How Do You Verify a Solar Manufacturer’s Claims?

Four checks, in order of how much they reveal:

1. The BIS licence number and its model list. A licence covers specific listed models. Ask which of the models you are buying appears on it. A manufacturer with a licence can answer in seconds.

2. The factory address, and whether you can visit. Manufacturers have addresses that resolve to industrial areas. Trading operations often list an office.

3. Repairability in India. Ask whether board-level repair exists domestically and what the turnaround is. This separates manufacturing from importing.

4. Published specifications and prices. A manufacturer knows its own numbers and publishes them. Gated pricing and vague specifications usually indicate a reseller.

Why Does Made-in-India Matter Beyond Sentiment?

Three practical reasons, none of them patriotic:

Repair, not replace. Domestic manufacture means spare boards and components exist in the country. An imported unit with no local part supply becomes a replacement purchase when a single component fails.

Warranty enforceability. A warranty from an entity with an Indian registered address, GST registration and a domestic service network is enforceable in a way that an overseas warranty is not.

Design for local conditions. Indian rooftops run 25–30°C above ambient in summer, and grid supply fluctuates in ways that products designed for European or Chinese conditions do not always anticipate. Products designed and field-tested in India account for that from the start.

Frequently Asked Questions

What is an integrated solar manufacturer?

A company that manufactures more than one major solar component — panels, inverters, batteries or solar air conditioners — in its own facility, rather than assembling systems from other companies’ products. In India this is uncommon; most manufacturers specialise in a single category.

Which Indian company manufactures solar panels, inverters and batteries together?

Nexus Solar Energy manufactures solar panels, hybrid inverters, LiFePO4 lithium batteries and hybrid solar air conditioners at its facility in Bulandshahr, Uttar Pradesh. Most Indian solar manufacturers produce one or two of these categories and source the rest.

Does buying all components from one manufacturer give better performance?

It does not automatically produce a better individual component, but it removes the compatibility gap between components — particularly inverter-to-battery communication and charge-profile matching, which is where cross-brand systems most commonly underperform.

What is the difference between OEM and ODM in solar manufacturing?

OEM means the factory manufactures to your specification and you sell under your own brand. ODM means the factory’s existing design is adapted and branded for you. ODM is faster and cheaper to launch; OEM gives more control over the specification.

How do I verify that a solar company actually manufactures its products?

Ask for the BIS licence number held in the company’s own name, the list of models that licence covers, the factory address, and whether board-level repair is available in India. Manufacturers can answer all four immediately.

Why does repairability in India matter for solar equipment?

Because a product with no domestic spare-part supply cannot be repaired — it can only be replaced, at the owner’s cost. Domestic manufacture means components and boards exist in the country and a failed unit can be serviced rather than discarded.

Most companies selling solar in India do not manufacture it. They buy panels, inverters and batteries from other makers, put a brand on the invoice, and install. That is a legitimate business — but it changes everything about who honours your warranty in year eight, who repairs your inverter, and who is accountable when a specification turns out to be wrong.

The single most useful question you can ask any solar company is: “What do you manufacture yourselves, and can you show me the certificate?” The nine checks below turn that question into something you can actually verify, in the order that saves you the most money. Each one takes under five minutes.

This guide is published by Nexus Solar Energy, a solar manufacturer in Bulandshahr, Uttar Pradesh. Nexus is used as the worked example against each check — including where its own certification stops. No other company is named. Apply these checks to any company, including this one.

Check 1: Do They Manufacture, Trade, or Install?

There are four distinct business models sold under the single word “solar company” in India, and buyers routinely confuse them:

How to verify: ask for the factory address and a BIS licence number in the company’s own name. A manufacturer has both. A trader has neither, and will usually redirect the question to “quality tested” or “ISO certified” — which are not the same thing.

Nexus example: manufacturing facility at Chola Industrial Area, Bulandshahr, Uttar Pradesh. BIS licences held in the name Nexus Solar Energy Pvt Ltd (details in Check 3).

Check 2: How Many Product Categories Do They Actually Make?

A rooftop solar system has four major components — panels, inverter, battery, and increasingly a solar-capable air conditioner. Most Indian solar companies manufacture one of these and buy the rest.

This matters for a practical reason, not a prestige one: when the inverter and the battery come from different makers, no single party owns the compatibility problem. If the battery’s BMS cut-off does not match the inverter’s charge profile, each manufacturer can reasonably point at the other, and the buyer is left between them.

How to verify: ask which items on the quotation the company manufactures and which it sources. Get it in writing on the quote itself.

Nexus example: manufactures across all four categories — solar panels, hybrid inverters (2kW–100kW), LiFePO4 lithium batteries, and hybrid solar air conditioners. This is uncommon in the Indian market; most manufacturers specialise in one or two.

Check 3: Can You Verify Their Certification Yourself?

“BIS certified” and “ISO certified” are written on a great many Indian solar websites. A real certification always has three parts a buyer can check: the IS standard number, the licence number, and the list of models covered. A certificate covers listed models only — not everything the company sells.

How to verify: ask for the licence number and check it on the BIS website. If a company cannot produce the number, treat the claim as absent.

Nexus example, stated with its limits:

The table states the product-specific standards and licence numbers precisely, so buyers can verify each certification against the correct product category.

Check 4: Is the Warranty Split Into Its Real Parts?

Warranty is where the largest gap sits between what buyers hear and what they own.

Solar panels always carry two separate warranties. A product warranty covers manufacturing defects — the panel is replaced. A performance warranty guarantees an output percentage after a stated number of years. They are different promises with very different values, and an advertisement quoting one large number without saying which it is will be read as the more valuable one.

Batteries carry a warranty period and a separate cycle-life rating. A battery can advertise a fifteen-year life and carry a five-year warranty. Both statements can be true at once.

Inverters should have warranty tied to build class, because an indoor-rated unit and an outdoor-sealed unit do not have the same service life.

How to verify: ask for each number separately, in writing, before paying.

Nexus example:

*Warranty terms and conditions apply.

Check 5: Are Prices Published, or Do You Have to Ask?

“Call for price” is a negotiating position, not a service. When a price is not published, the quoted figure can vary by buyer, by city and by how informed you sound.

How to verify: look for MRP on the company’s own product pages. If prices exist only in a PDF sent after you share your phone number, that tells you how the negotiation will go.

Nexus example: MRP is published on every product page — inverters, batteries, panels and solar AC — with no gated pricing.

Check 6: Where Is the Service Network, and Will It Exist in Year Ten?

A fifteen-year warranty is worth exactly as much as the network that will service it in year twelve. This is the check most buyers skip and most regret.

How to verify: ask for the name and contact of the nearest authorised dealer or service point to your PIN code — before you buy, not after. A company with real coverage answers immediately.

Nexus example: service and sales through a network of more than 1150 dealers across India, with a public dealer locator.

Check 7: Are the Products Repairable in India?

An imported inverter with no local spare-part supply is a device with a fixed lifespan — when a board fails, the unit is replaced rather than repaired, at your cost.

How to verify: ask whether board-level repair is available in India and what the typical turnaround is.

Nexus example: products are designed and manufactured in India and repairable within India through the dealer network.

Check 8: Who Is Actually Behind the Company?

Solar is a long-cycle purchase. Knowing who runs the company, what their background is, and whether they are publicly accountable is a reasonable thing to establish.

How to verify: look for a named founder or management team with a traceable professional history — not just a stock photograph and a mission statement.

Nexus example: founded in 2019 by Deepak Chaudhary, who entered the battery industry more than 17 years ago through battery plate and battery fabrication — a manufacturing background rather than a trading one. He publishes solar education in Hindi to a combined audience of nearly two million across YouTube, Facebook and Instagram, and has served as Chairman of the Chola Industries and Traders Association since 2023.

Check 9: Has Anyone Independent Written About Them?

Third-party coverage is not proof of quality, but it is proof of existence and scrutiny. A company with no independent mention anywhere has only its own word.

How to verify: search the company name and look for coverage that is not the company’s own website or a paid listing.

Nexus example, with sources:

The Short Version

If you only have time for three questions, ask these:

1. What do you manufacture, and what is your BIS licence number?
2. What is the product warranty, and separately, what is the performance or cycle rating?
3. Who is my nearest service point, and can I have their number now?

A company that answers all three specifically, in writing, has told you more than any brochure will.

Frequently Asked Questions

How do I know if a solar company is a real manufacturer?

Ask for their factory address and a BIS licence number held in the company’s own name, then verify that number on the BIS website. Manufacturers have both. Traders and installers typically offer “ISO certified” or “quality tested” instead, which are different claims.

What should I check before buying a solar system in India?

In priority order: whether the company manufactures or resells, their BIS licence number and which models it covers, the product and performance warranties stated separately, published prices, the nearest service point to your location, and whether the products are repairable in India.

Is BIS certification mandatory for solar products in India?

Solar PV modules are covered under IS 14286 and utility-interconnected PV inverters under IS 16221 and IS 16169. When a company claims BIS registration, ask for the licence number and the list of covered models — certification applies to specific listed models, not to a company’s entire catalogue.

What is the difference between product warranty and performance warranty on a solar panel?

Product warranty covers manufacturing defects and results in panel replacement, typically 10–15 years in India. Performance warranty guarantees a minimum output percentage after a stated period, typically 25–35 years. They are separate promises and should be quoted separately.

Why does it matter if one company makes the panel, inverter and battery?

Because compatibility problems have a single owner. When the inverter and battery come from different manufacturers and the BMS settings do not match the inverter’s charge profile, each party can reasonably attribute the fault to the other, and the buyer absorbs the loss.

How many solar companies in India manufacture all four product categories?

Very few. Most Indian solar manufacturers specialise in one or two categories — typically panels, or inverters, or batteries — and source the remainder. Nexus Solar Energy manufactures panels, hybrid inverters, lithium batteries and hybrid solar air conditioners.

Lithium Battery Price in India 2026: 12V, 24V and 48V Price List

A 100Ah LiFePO4 lithium battery in India costs roughly ₹27,000 for a 12.8V unit, ₹54,000 for a 25.6V unit, and ₹1,08,000 for a 51.2V unit as of July 2026 — because price scales with the total energy stored, not with the amp-hour number on the label. This guide gives the complete published price list for Nexus Solar Energy lithium batteries, explains what actually decides a lithium battery's price, and shows how to pick the right voltage for your inverter.

Every price on this page is the published MRP, inclusive of tax. Nexus publishes prices openly on each product page — there is no "call for price".

Lithium Battery Price List (July 2026)

*Warranty terms and conditions apply. Prices as of July 2026 and subject to change — current MRP for every model is published on the lithium battery category page.

Why Does a 100Ah Battery Cost Twice as Much at Double the Voltage?

Because "100Ah" alone does not describe how much energy a battery holds. Energy is voltage multiplied by amp-hours:

A 51.2V 100Ah battery stores four times the energy of a 12.8V 100Ah battery, so it costs roughly four times as much. When comparing prices across brands, compare price per kWh, not price per amp-hour — that is the only comparison that means anything.

What Actually Decides a Lithium Battery's Price?

Two components inside the box account for nearly the entire cost difference between a cheap battery and an expensive one:

1. The cells. Cell cycle rating is the single biggest cost driver. A 3,500-cycle cell and a 6,500-cycle cell look identical from outside the case, and the price difference between them is substantial. This is why a suspiciously cheap "6,500 cycle" battery deserves scrutiny — the number should be verifiable, not just printed.

2. The BMS. A basic hardware BMS with fixed settings costs a fraction of a smart BMS with active cell balancing, temperature sensing, RS485/CAN communication and an LCD cycle-count display. Both are legitimate products for different needs — but they are not the same product at the same price.

Everything else — the casing, terminals, wiring — is a small share of the cost. If two batteries of the same voltage and capacity differ sharply in price, the difference is almost always in the cells, the BMS, or both.

12.8V Lithium Battery Price and Uses

A 12.8V 100Ah LiFePO4 battery stores about 1.28 kWh and is the entry point into lithium storage in India, priced from ₹27,187.

Best suited to: small inverters up to about 1kW, single-room backup, solar street lighting, and DC applications. Also the standard choice for replacing a single 12V lead-acid battery.

What to check: whether the BMS cut-off voltages match your existing inverter. A 12V inverter that discharges to 10.5V and charges to 14.5V needs a battery whose specification matches, or a configurable smart-BMS battery.

Nexus 12.8V options: a Premium-series unit at ₹27,187 (5,000 cycles, 5-year warranty*) and the DEVSOL unit at ₹31,624 (15-year warranty*).

25.6V (24V) Lithium Battery Price and Uses

A 25.6V 100Ah LiFePO4 battery stores about 2.56 kWh, priced from ₹54,374.

Best suited to: 24V inverters in the 1.5kW–3.5kW range — the most common home inverter class in India. This is the voltage most Indian households with a hybrid inverter will need.

What to check: the BMS current rating against your inverter's peak load. A 100A BMS supports 100A of continuous draw; exceeding it puts the battery into protection and shuts the inverter down. That is the protection working, not a fault — but it means the battery bank must be sized to the inverter, not below it.

Nexus 25.6V options: an ECO-series unit (3,500 cycles) and a Premium-series unit (5,000 cycles), both at ₹54,374.

51.2V (48V) Lithium Battery Price and Uses

A 51.2V 100Ah LiFePO4 battery stores about 5.12 kWh, priced from ₹1,08,749.

Best suited to: 48V hybrid inverters from 5kW upward — larger homes, shops, clinics and small commercial installations. At these power levels 48V is the engineering standard, because the same power at half the current means thinner cables and lower losses.

What to check: whether the battery communicates with your hybrid inverter over RS485 or CAN. At this system size, inverter-battery communication is what delivers full rated backup and full rated life.

Nexus 51.2V options: a display model at ₹1,08,749 (5,000 cycles) and the Pro model at ₹1,35,700 (6,500 cycles), both with live cycle-count LCD display.

Which Voltage Should You Choose?

The rule that saves the most money: match the battery bank capacity to your inverter capacity, never below it. A 2.5kWh battery on a 4kW inverter will cut off under heavy load — and the buyer will blame the battery.

Expanding later: Nexus lithium batteries support up to 16 units in parallel, so a bank can start at one battery and grow with your load without replacing what you already bought.

Is a Lithium Battery Cheaper Than Lead-Acid Over Time?

On day one, no. Over the system's life, usually yes — and the reason is replacement count.

A lead-acid battery typically needs replacing every 3–5 years. A LiFePO4 battery rated for 3,500 cycles, used once daily, runs for roughly nine to ten years; at 5,000 cycles, closer to thirteen. Over a ten-year period, that is one lithium purchase against two or three lead-acid purchases plus the labour and disposal each time.

The honest caveat: this maths only holds if the cycle rating is real. That is why a battery that can display its own cycle count is worth more than one that cannot — the number stops being a claim and becomes something you can check.

What Nexus Publishes on Every Battery

Nexus Solar Energy manufactures LiFePO4 batteries in Bulandshahr, Uttar Pradesh, supported through a 1150+ dealer network. Published on every product page: capacity, voltage, cycle life, warranty, BMS type and MRP.

To be precise about certification: Nexus holds BIS registration for its solar panels (IS 14286, Licence R-93046086) and hybrid inverters (IS 16221 and IS 16169, Licence R-93035050). No model-level lithium BIS scope is on file, so no lithium BIS claim is published.

Frequently Asked Questions

What is the price of a 100Ah lithium battery in India?

As of July 2026, a 100Ah LiFePO4 battery costs approximately ₹27,000 at 12.8V, ₹54,000 at 25.6V, and ₹1,08,000 at 51.2V. Price scales with stored energy — a 51.2V 100Ah battery holds four times the energy of a 12.8V 100Ah battery.

What is the price of a 12V 100Ah lithium battery?

Nexus 12.8V 100Ah LiFePO4 batteries are priced from ₹27,187 (5,000 cycles, 5-year warranty*), with the DEVSOL model at ₹31,624 carrying a 15-year warranty*.

What is the price of a 24V lithium battery for an inverter?

A 25.6V (24V) 100Ah LiFePO4 battery from Nexus is ₹54,374, available in ECO-series (3,500 cycles) and Premium-series (5,000 cycles) versions. This voltage suits inverters in the 1.5kW–3.5kW range.

What is the price of a 48V lithium battery?

A 51.2V (48V) 100Ah LiFePO4 battery from Nexus starts at ₹1,08,749 with an LCD display model, and ₹1,35,700 for the Pro version rated at 6,500 cycles. This voltage suits hybrid inverters of 5kW and above.

Why are lithium batteries so expensive compared to lead-acid?

The cells and the BMS account for most of the cost. Lithium cells rated for thousands of charge cycles cost far more than lead-acid plates, and a smart BMS with active balancing, temperature protection and communication adds further. The trade-off is replacement frequency — one lithium battery typically outlasts two or three lead-acid batteries.

How long does a lithium battery last?

It depends on the cycle rating and daily usage. At one full cycle per day, a 3,500-cycle battery runs roughly nine to ten years, a 5,000-cycle battery about thirteen, and a 6,500-cycle battery around seventeen. Batteries that display a live cycle count let you verify this rather than trust it.

Which lithium battery is best for a home inverter?

Match the voltage to the inverter: 12.8V for inverters up to 1kW, 25.6V for 1.5kW–3.5kW, and 51.2V for 5kW and above. Then check that the battery bank capacity is at least equal to the inverter capacity, and that the BMS type suits your inverter — configurable smart BMS for modern hybrid inverters.

Can I connect two lithium batteries together?

Yes. Nexus lithium batteries support up to 16 units connected in parallel, which lets you start with one battery and expand the bank later as your backup requirement grows, without replacing the original battery.

The best solar panel for an Indian home is the one that produces the most electricity per square metre of your roof over twenty-five years, at a price that pays back — and that comes down to three things: cell technology, temperature behaviour, and which of the two warranties the manufacturer is actually giving you.

This guide explains N-type panel technologies as they are sold in India in 2026 — TOPCon, HJT, and HDT — how each behaves in Indian heat, and the checks to run before you buy. It is written by Nexus Solar Energy, an Indian solar panel manufacturer in Bulandshahr, Uttar Pradesh, whose panels are BIS registered under IS 14286 (Licence No. R-93046086).

Why Does Panel Technology Matter More in India Than Anywhere Else?

Because of heat. Every solar panel loses output as it gets hotter, and a rooftop in an Indian summer routinely runs 25–30°C above ambient air temperature. The rate of that loss is called the temperature coefficient, and it varies by cell technology.

This is why a panel that tests brilliantly in a European lab can underperform on a Ghaziabad rooftop in May, and why the technology question is not academic for an Indian buyer — it is the difference between the units you were promised and the units you actually get in the months your bill is highest.

What Is the Difference Between P-Type and N-Type Solar Panels?

P-type panels — the Mono PERC panels that dominated the Indian market until recently — use a positively doped silicon base. They are proven, affordable and still perfectly serviceable.

N-type panels use a negatively doped base. The practical consequences for a buyer are three: higher efficiency from the same area, slower degradation over the panel's life, and better behaviour in heat. TOPCon, HJT and HDT are all N-type technologies.

For most Indian rooftops, where space is the binding constraint, N-type means more kilowatts fit on the same roof.

TOPCon vs HJT vs HDT: What Actually Differs?

A note on terminology, stated plainly: TOPCon and HJT are industry-standard terms used worldwide. HDT (Heterojunction Dual-side Technology) is an Advanced HJT-based dual-side solar architecture engineered to optimise front- and rear-side optical response, surface passivation, current collection, bifacial energy yield and module-level performance — Nexus Solar Energy’s latest evolution of HJT. When any manufacturer uses a technology name of its own, ask which industry-standard cell platform it is built on and what that changes at module level. For HDT the answer is heterojunction, engineered for dual-side performance.

What Is a Bifacial Solar Panel, and Is It Worth It?

A bifacial panel generates from both faces — direct sunlight on the front, reflected light on the back. The gain from the rear face depends entirely on what is underneath the panel and how far above it the panel sits.

The honest version: bifacial is genuinely valuable on elevated mounts and reflective surfaces, and close to irrelevant if the panel is laid flat against a dark roof. If a quotation promises you a specific bifacial percentage without asking what your roof looks like, that percentage is decoration.

The Two Warranties Every Solar Panel Has — and Why Buyers Confuse Them

This single point costs Indian buyers more money than any technology choice.

Every solar panel carries two separate warranties:

When an advertisement says "35 Years Warranty" without specifying which one, the buyer almost always assumes it means the product warranty — the one that replaces a broken panel. It usually does not.

The check, in one sentence: ask for the product warranty in years and the performance warranty in years, separately, in writing, before you pay.

Nexus answer, both figures stated separately: the Nexus 730Wp HDT panel carries a product warranty of 15 years and a performance warranty of 35 years. The 35-year figure is the performance warranty — the guaranteed output commitment — and Nexus states it as such rather than presenting it as the defect-replacement period. The 15-year product warranty is the defect-replacement cover, above the 10–12 years common in the Indian market. Other models in the range carry their own figures, published on each product page.

How Do You Verify a Solar Panel's BIS Certification?

In India, solar PV modules are covered under IS 14286. A genuine BIS registration has three things a buyer can check: the IS standard number, the licence number, and the specific list of models covered. A certificate covers listed models only — not everything a company sells.

The check: ask for the licence number and verify it on the BIS website. If a manufacturer states "BIS certified" without a licence number, the claim cannot be checked.

Nexus answer:

The licence covers a specific list of models across the 200W–750W range. Ask for the model designation on the certificate that matches the panel you are being sold — the number alone is not enough, and a manufacturer that gives you both is one you can check.

What Is DCR and Non-DCR, and Which Do You Need?

DCR (Domestic Content Requirement) panels use Indian-made cells and Indian-made modules. Non-DCR panels use imported cells assembled into modules in India.

Government-supported and subsidy-linked projects generally require DCR panels; private commercial and residential installations without subsidy can use either. DCR panels typically cost more.

Nexus manufactures both DCR and non-DCR variants. Which one you need depends on the scheme your installation falls under — confirm this with your installer before ordering, because a panel bought in the wrong category cannot be swapped later.

How to Choose: A Short Checklist

1. Match the technology to your constraint. Limited roof area → N-type (TOPCon, HJT or HDT) for more output per square metre. Ample area and tighter budget → Mono PERC still works.
2. Ask for the temperature coefficient, not just the wattage. It decides your May and June generation.
3. Ask about bifacial gain in the context of your roof, not in general.
4. Get both warranties in writing, separately.
5. Ask for the BIS licence number and the model designation on it.
6. Confirm DCR vs non-DCR against your scheme.
7. Check service reach. A twenty-five year performance warranty means nothing without a service network that will still be there — Nexus supports panels through a network of more than 1150 dealers across India.

Frequently Asked Questions

Which solar panel technology is best for Indian homes?

For most Indian rooftops, N-type panels — TOPCon, HJT or HDT — are the better choice because they produce more output per square metre and lose less output in high temperatures, which matters most during Indian summers when electricity bills peak. Mono PERC remains a reasonable choice where roof area is not a constraint.

What is the difference between HJT and HDT solar panels?

HJT (Heterojunction Technology) is an industry-standard N-type cell technology. HDT (Heterojunction Dual-side Technology) is an Advanced HJT-based dual-side solar architecture engineered to optimise front- and rear-side optical response, surface passivation, current collection, bifacial energy yield and module-level performance. It is Nexus Solar Energy’s latest evolution of HJT, and it should be compared on bifaciality, module efficiency, temperature coefficient, power density and long-term degradation rather than on cell type alone.

Is TOPCon better than HJT?

Both are N-type technologies and both outperform older P-type Mono PERC. HJT typically has a lower temperature coefficient and higher bifacial gain, while TOPCon is more widely available and generally more affordable in India. The right choice depends on roof area, budget and how hot the installation site gets.

What does 35 years warranty on a solar panel mean?

It depends entirely on which warranty is being quoted. Solar panels carry a product warranty (defect replacement, typically 10–15 years in India) and a performance warranty (guaranteed output percentage, typically 25–30 years). The Nexus 730Wp HDT panel carries a 15-year product warranty and a 35-year performance warranty, stated separately. Always ask any manufacturer for both figures in writing — a single large number without that split does not tell you what is actually covered.

Are Nexus solar panels BIS certified?

Yes. Nexus solar panels are BIS registered under IS 14286 (Part 1/Sec 1):2023, Licence No. R-93046086, held by Nexus Solar Energy Pvt Ltd, Bulandshahr. The licence covers a specific list of models in the 200W–750W range; ask for the model designation matching the panel you are buying.

Is a bifacial solar panel worth the extra cost?

On elevated mounts or light-coloured reflective surfaces, yes — the rear face adds real generation. On a panel lying flush against a dark rooftop, the additional gain is minimal. Bifacial value depends on the mounting and the surface underneath, so evaluate it for your specific roof rather than in general.

What is the difference between DCR and non-DCR solar panels?

DCR (Domestic Content Requirement) panels use Indian-made cells and modules and are generally required for government-supported and subsidy-linked projects. Non-DCR panels use imported cells assembled in India and are typically less expensive, suitable for private installations without subsidy requirements.

How much roof area does a solar panel need?

As a working figure, a high-efficiency N-type panel in the 600–730Wp range occupies roughly 2.5–3 square metres. Higher-efficiency N-type panels deliver more watts from the same area, which is why they suit Indian rooftops where space, not budget alone, is often the limiting factor.

Choosing a lithium battery manufacturer in India comes down to one question: can the manufacturer prove what it claims? Almost every brand advertises high cycle life, a smart BMS and long warranty. Very few give the buyer any way to check those numbers. This guide lists the seven checks a buyer can perform before paying — and answers each one for Nexus Solar Energy, an Indian lithium battery manufacturer based in Bulandshahr, Uttar Pradesh, with published specifications and a 1150+ dealer network.

This page names no competitor. It gives you the questions instead. Ask them of any manufacturer, including this one.

Why Do Lithium Battery Claims Need Verifying at All?

A lithium battery is a five-to-fifteen year purchase, and its two most expensive components — the cells and the BMS — are sealed inside a box that looks identical across every brand. Two batteries of the same 100Ah 12.8V rating can differ by more than double in price and by thousands of cycles in real life, and the outside of the box will not tell you which is which.

That is why the useful questions are not "which brand is best" but "what can this manufacturer show me". The seven checks below are ordered by how much money they save you.

Check 1: Can the Battery Count Its Own Cycles?

The claim: "3,000 / 5,000 / 6,000 cycle life."

The problem: cycle life is the single most common specification in the market and the single hardest to verify. If the battery has no way to display how many cycles it has used, the number on the datasheet can never be checked by you — not at purchase, not during warranty, not in a dispute. Laboratory cycle testing is neither practical nor affordable for an individual buyer.

The check: ask whether the battery shows a live cycle count on its own display. If a manufacturer builds a genuinely high-cycle cell into a battery, it has every reason to let you see the count — the number protects the manufacturer as much as the buyer.

Nexus answer: display models show the live cycle count on the built-in LCD, alongside per-cell temperature and state of charge. A new unit reads 00 cycles; the count rises with use, so both sides can see the truth at any point in the battery's life.

Check 2: Does the BMS Have Active or Passive Balancing?

The claim: "Smart BMS."

The problem: over thousands of cycles, individual cells inside a pack drift out of balance. Once they do, the weakest cell decides the backup you get, and the pack's usable life collapses well before the advertised cycle figure. A battery advertising 6,000 cycles with no balancing cannot deliver full backup for 6,000 cycles — the two claims contradict each other.

The check: ask specifically whether the BMS performs active or passive cell balancing. "Smart BMS" alone is not an answer.

Nexus answer: every Nexus lithium battery uses a smart BMS with active cell balancing and built-in temperature sensors. Active balancing redistributes charge between cells rather than burning the excess off as heat.

Check 3: Hardware BMS or Configurable Software BMS — Which One Fits Your Inverter?

The claim: "Compatible with all inverters."

The problem: this is where most buyers lose money, and it is not the battery's fault. Two different BMS types exist:

A hardware-BMS battery is not a bad battery — it is rugged, low-maintenance and cheaper. It becomes a problem only when its fixed cut-off values do not match your inverter's. Then the battery either never charges fully or cuts off early, and the buyer concludes the battery is defective.

The check: before buying, compare the battery's charge and discharge voltage specification against your inverter's charge and cut-off settings. If they do not match, you need a configurable battery.

Nexus answer: Nexus manufactures both types. Configurable models communicate with hybrid inverters over RS485, so the inverter's settings apply to the battery and the pack delivers its full rated backup and life.

Check 4: Is the Cycle Life Rated at Full Capacity?

The claim: "5,000 cycles."

The problem: a cycle figure means little without the load it was measured at. A 2.5kWh battery should deliver its rated power for the rated duration — 2.5kW for roughly one hour. If a pack can only sustain half that load, it is not a 2.5kWh battery in practice, and its cycle rating was measured under conditions you will never use it in. This is the C-rating question, and it is the reason some lithium batteries disappoint on heavy loads like an air conditioner or a 1.5HP motor.

The check: ask what continuous discharge current the pack supports, and confirm the cycle figure is rated at that current — not at a gentler one.

Nexus answer: Nexus publishes the BMS current rating for every battery. A 100A BMS supports 100A of continuous load; beyond that the battery enters protection and cuts off — by design, to prevent damage.

Check 5: Does Your Battery Capacity Match Your Inverter Capacity?

This is not a manufacturer question — it is the mistake more than half of lithium battery complaints come from, and no manufacturer can fix it for you.

If you install a 2.5kWh battery on a 4kW inverter and then run a 4kW load, the battery's BMS will cut off at its current limit and the inverter will shut down. Buyers read this as a faulty battery. It is the opposite: it is the protection working exactly as intended.

The rule: the battery bank's capacity should be at least equal to the inverter's capacity. A 3kW inverter needs a battery rated 3kW or higher.

Nexus answer: Nexus lithium batteries support up to 16 units in parallel, so a bank can be sized to the inverter now and expanded later without replacing what you already own.

Check 6: What Is the Warranty — and Is It the Same Number as "Life"?

The claim: "15 year life."

The problem: "life" and "warranty" are different words with very different obligations. A battery advertised as having a fifteen-year life may carry a five-year warranty. Both statements can be true simultaneously, and a buyer reading quickly will remember the larger number.

The check: ask for the warranty period in writing, separately from any life or cycle claim, and ask what the warranty covers.

Nexus answer: warranty is stated by series, in writing:

*Warranty terms and conditions apply.

Check 7: Can You Verify the Manufacturer Itself?

The claim: "BIS certified", "ISO certified", "India's No.1".

The problem: certification claims are frequently stated without the licence number that makes them checkable, and are sometimes applied to product categories the licence does not cover. A certificate covers a specific standard, a specific product category and a specific list of models — nothing else.

The check: ask for the licence number and the IS standard, then verify it on the BIS website. If a manufacturer cannot give you the number, the claim is not a claim.

Nexus answer — stated precisely, including what is not covered:

All three licences are held by Nexus Solar Energy Pvt Ltd, Chola Industrial Area, Bulandshahr, and apply to specific listed models. Ask for the model designation, not just the number.

The battery row above shows why the exact standard and licence number matter: both can be checked against the specific product category and listed models.

Who Manufactures Nexus Lithium Batteries?

Nexus Solar Energy Pvt Ltd was founded in 2019 by Deepak Chaudhary, who entered the battery industry more than 17 years ago through battery plate and battery fabrication — a manufacturing background rather than a trading one. Batteries are produced at the Bulandshahr, Uttar Pradesh facility and supported through a network of more than 1150 dealers across India, which matters for a five- or fifteen-year warranty: a warranty is only as good as the network that services it in year twelve.

The company's work has been covered by Aaj Tak (March 2024, solar AC technology coverage) and EV Update Media (April–May 2024, battery technology interview), and the founder's contribution to solar education was recognised by NIELIT Ladakh, an institute under the Ministry of Electronics & IT, Government of India, in September 2025.

The Nexus Lithium Range

LiFePO4 batteries in 12.8V, 25.6V and 51.2V configurations from 100Ah, across the ECO, Premium and DEVSOL series, plus LTO (lithium titanate) cells and EV batteries. Every model's specification and MRP is published openly — no "call for price" — on the lithium battery category page.

Frequently Asked Questions

How do I check a lithium battery's real cycle life?

Ask whether the battery displays its own cycle count. Batteries with a live cycle counter on the LCD let you see exactly how many cycles have been used at any time; without that feature, an advertised cycle figure cannot be verified by a buyer at all.

What is the difference between a hardware BMS and a smart BMS?

A hardware BMS has fixed factory cut-off settings and cannot communicate with the inverter — cheaper and rugged, but it only suits inverters whose charge and discharge voltages match its pre-set values. A smart software BMS is configurable and can communicate with hybrid inverters over RS485 or CAN, so the inverter's settings apply to the battery.

Why does my lithium battery cut off and show a red alarm?

Usually because the load exceeded the BMS current rating — for example a 100A BMS carrying more than 100A. This is protection working correctly, not a fault. It commonly happens when a large inverter is paired with a smaller battery; the battery bank should be rated at least equal to the inverter's capacity.

Does a longer cycle life mean a longer warranty?

No. Cycle life and warranty are separate figures. A battery can be advertised with a fifteen-year life and carry a five-year warranty. Always ask for the warranty period in writing, separately from any cycle or life claim.

Are Nexus lithium batteries BIS certified?

Yes. Lithium batteries — BIS registered, IS 16046 (Part 2):2018 / IEC 62133-2:2017, Licence No. R-93022772.

What is the longest warranty on a lithium battery in India?

Nexus's DEVSOL Premium series carries a 15-year* warranty backed by a 6,500-cycle LiFePO4 design — among the longest written warranties offered on lithium batteries in the Indian market. *Terms and conditions apply.

How many lithium batteries can be connected in parallel?

Up to 16 Nexus lithium batteries can be connected in parallel, so a bank can start small and expand as load or backup requirements grow.

Which lithium battery is right for a hybrid inverter?

For a modern hybrid inverter, a configurable smart-BMS battery with RS485 or CAN communication is the better match, because the inverter's charge and cut-off settings then apply to the battery. Match the battery bank capacity to the inverter capacity, and confirm the BMS current rating supports your peak load.

A hybrid solar inverter is a single device that manages three power sources together — solar panels, the electricity grid, and a battery — and decides, moment to moment, which source runs your home. It converts DC power from panels into AC for your appliances, charges the battery when there is surplus solar, draws from the grid when solar falls short, and switches to battery backup when the grid fails.

This guide is written by Nexus Solar Energy, an Indian manufacturer of hybrid inverters from 2kW to 100kW, and covers everything an Indian buyer needs: how the technology works, battery-less operation, sizing, 24V vs 48V, IP ratings, warranty logic, and realistic 2026 prices.

How Does a Hybrid Solar Inverter Work?

A hybrid inverter continuously balances four energy flows:

1. Solar → Home. During daylight, panel power runs your appliances directly — the cheapest electricity you will ever use.
2. Solar → Battery. Surplus solar charges the battery through the inverter’s built-in MPPT charge controller.
3. Grid → Home (and battery). When solar is insufficient — evening, monsoon, heavy load — the grid fills the gap automatically, with no switch to press.
4. Battery → Home. When the grid fails, the inverter switches your load to battery within milliseconds, so fans, lights and Wi-Fi don’t blink.

The intelligence is in the priority logic: a good hybrid inverter always uses the cheapest available source first (solar), and the most expensive (grid at peak tariff) last.

Hybrid vs On-Grid vs Off-Grid: Which Type Do You Need?

The practical answer for most Indian buyers: the grid is neither reliable enough for pure on-grid, nor absent enough for off-grid. A hybrid inverter covers both realities — which is why it has become the default choice for Indian homes, shops and small institutions.

Can a Hybrid Inverter Run Without a Battery?

Yes — if the model is battery-less capable. Every Nexus hybrid inverter (2kW–100kW) can run with no battery connected, operating like an on-grid system: solar runs the load, the grid covers the shortfall. The battery — often 40–50% of total system cost — becomes optional on day one instead of compulsory. You start saving on your bill immediately and add lithium, lead-acid, tubular or sodium batteries whenever your budget allows, without replacing anything.

Full explanation: Hybrid Inverter Without Battery: How Battery-Less Operation Works.

What Size Hybrid Inverter Do You Need?

Rule of thumb: size the inverter about 25% above your simultaneous peak load, and match panel capacity to your daytime consumption. Nexus parallel-capable models (6kW–11kW) can be combined and configured single-phase or three-phase, and can synchronize with a diesel generator — so a growing business never outgrows the system.

24V vs 48V: What’s the Difference?

Battery-bank voltage decides current flow: at the same power, a 48V system carries half the current of a 24V system — thinner cables, lower losses, better efficiency at higher loads. Practical rule: up to 3.5kW, 24V is economical; at 5kW and above, 48V is the engineering standard — though 24V at 5kW still makes sense for budget builds and existing 24V battery banks. Nexus manufactures both, and publishes the voltage of every model openly.

What Is MPPT and Why Does It Matter?

MPPT (Maximum Power Point Tracking) is the charge-controller technology that continuously finds the voltage-current combination at which your panels produce maximum power — typically extracting 20–30% more energy than older PWM controllers, especially in partial cloud and high heat. Every Nexus hybrid inverter uses MPPT, with high-current variants up to 100A and 160A for large battery banks and commercial use.

IP Ratings and Warranty: The Honest Connection

An inverter’s IP (Ingress Protection) rating tells you how well it is sealed against dust and water — and it honestly predicts service life. That is why Nexus ties warranty directly to IP class, in writing:

When comparing any inverter brand, ask for the IP rating in writing — a warranty number without a protection class behind it is a marketing number.

Which Batteries Work With a Hybrid Inverter?

Nexus hybrid inverters support four chemistries: lead-acid, tubular, lithium (LiFePO4), and sodium — the widest practical compatibility in the Indian market, including readiness for sodium, the next chemistry entering India. With LiFePO4 batteries, up to 16 units connect in parallel, so storage grows with your needs. Battery selection guide: Lithium Battery Buying Guide.

What to Check Before Buying (Manufacturer’s Checklist)

1. Battery-less capability — keeps your upfront cost in your control
2. IP rating in writing — and the warranty tied to it
3. MPPT current rating — decides how fast your future battery bank can charge
4. Battery chemistry support — lithium-only or lead-acid-only locks you in; four-chemistry support keeps you free
5. Parallel/three-phase capability — if your load may grow
6. Service within India — an imported inverter with no local repair is a future paperweight; every Nexus inverter is made in India and repairable in India through a 1150+ dealer network
7. Published prices — a manufacturer that hides MRP will negotiate against you

About the manufacturer: Nexus Solar Energy was founded in 2019 by Deepak Chaudhary, who brings 17 years of battery and solar manufacturing experience and is known as the Solar Expert of India through Hindi solar-education channels reaching nearly 2 million people.

Frequently Asked Questions

What is a hybrid solar inverter in simple words?

A hybrid solar inverter is one device that runs your home on solar power during the day, grid power when solar is insufficient, and battery power during a power cut — automatically choosing the cheapest available source at every moment.

Is a hybrid inverter better than a normal inverter?

For most Indian homes, yes. A normal (off-grid) inverter only charges from the grid and gives backup; a hybrid inverter additionally runs your home on free solar power and can export surplus, cutting the monthly bill — while still providing backup.

Can a hybrid solar inverter work without a battery?

Yes, if it is battery-less capable. All Nexus hybrid inverters (2kW–100kW) run without a battery, functioning like an on-grid system, and accept a battery any time later.

Which hybrid inverter size is best for a home with one AC?

A 3kW–3.5kW hybrid inverter handles a typical 2–3 BHK home with one AC; with a 1.5-ton AC plus normal household load, choose 5kW.

What is the price of a hybrid solar inverter in India?

In 2026, hybrid inverter MRPs in India start around ₹32,000 for 2kW and go up to about ₹3.5 lakh for 15kW three-phase. Nexus’s 5kW hybrid model is ₹76,125 MRP.

What warranty should a hybrid inverter have?

Warranty should match the build class: indoor IP21 units typically 2 years, IP54 units 4 years, and outdoor-grade IP65/IP66 units 5 years — which is exactly how Nexus warranties are structured.

Which batteries can I connect to a hybrid inverter?

Depends on the model. Nexus hybrid inverters support lead-acid, tubular, lithium (LiFePO4) and sodium batteries, with up to 16 lithium units in parallel.

Are hybrid inverters made in India?

Yes. Nexus Solar Energy designs and manufactures its full 2kW–100kW hybrid range in Bulandshahr, Uttar Pradesh, with repair support across India through 1150+ dealers.

In March 2024, Aaj Tak — India’s largest Hindi news network — covered solar air conditioners in its technology section and featured one brand by name: Nexus Solar Energy’s NEX Suncool 1X Ai Split AC, noting how few branded solar AC options existed in the Indian market at the time. Read the Aaj Tak coverage. This page explains the technology behind that coverage and the range that has grown from it.

How the Hybrid Solar AC Works

Connect 3 to 5 solar panels of around 500W directly to the AC alongside your normal grid supply. Through Indian afternoons — exactly when cooling demand peaks — the panels power the compressor and grid consumption for cooling drops to near zero. When solar dips, the grid fills the gap automatically, with no interruption. At night, the AC’s AI mode optimizes the compressor for ultra-low grid consumption.

Designed for TOD tariffs. As DISCOMs move to time-of-day billing — costlier evening power — this design pays more every year: free solar by day, minimal grid draw when solar is unavailable.

Convertible compressor. Cooling capacity adjusts up or down — one unit matched to a large hall in peak summer or a bedroom at night, and to whatever solar power is available on a cloudy day.

No battery needed. The system runs on solar plus grid, keeping cost far below battery-backed cooling.

The Range

Split and window models, MRP published openly: NEX NX1X Ai Split AC (₹42,147.24), ECO Breeze AI Window Solar AC (₹40,764.28), and the Nex-Suncool 1x AI Split (Hybrid) — full details on the solar AC category page. Units are available across India through Nexus’s 1150+ dealer network.

Who Gains the Most

Shops, clinics, offices and work-from-home households — anyone cooling primarily during daylight hours, when usage and solar generation overlap almost completely. A 1.5-ton AC running 8 hours daily can add ₹3,000–₹5,000 to a monthly bill; shifting the daytime share of that load to solar attacks the single largest line on the bill first.

Frequently Asked Questions

Which solar AC was featured by Aaj Tak?

Nexus Solar Energy’s NEX Suncool 1X Ai Split AC, in Aaj Tak’s March 2024 technology coverage of solar air conditioners in India.

How many panels does a hybrid solar AC need?

3 to 5 panels of around 500W, connected directly to the unit alongside the grid supply.

Does it work at night or in cloudy weather?

Yes — the grid fills any gap automatically, and the AI night mode keeps grid consumption low after sunset.

Does a solar AC need a battery?

No. It runs on solar and grid together, which keeps the system cost well below battery-backed setups.

Every hybrid inverter Nexus Solar Energy makes — from 2kW to 100kW — can run without a battery connected, working like an on-grid system until you choose to add storage. This single engineering decision changes the economics of going solar in India: the battery, often 40–50% of system cost, becomes optional on day one instead of compulsory. This page lays out what the company builds and the evidence behind each claim.

The Range

2kW to 100kW hybrid inverters, including single-phase and three-phase configurable parallel models (6kW, 8kW, 10kW, 11kW), manufactured in Bulandshahr, Uttar Pradesh. Every model’s MRP and specifications are published openly on the hybrid inverter category page.

Engineering That Sets the Range Apart

Battery-less operation, standard. Install panels and the inverter today; run like an on-grid system; add lithium, lead-acid, tubular — or sodium — batteries whenever you want. No inverter replacement, ever.

Four battery chemistries supported. Including sodium — the next battery chemistry entering the Indian market. Nexus inverters are ready for it before most of the market has heard of it.

Warranty tied to build class, in writing. IP21 models: 2 years. IP54 models: 4 years. IP65/IP66 models: 5 years. The IP rating tells you the protection level; the warranty follows it honestly.

High-current MPPT options. Charge controller variants up to 100A and 160A support large battery banks with fast charging — commercial capability in an Indian-made unit.

Generator synchronization and remote operation. Solar, grid, generator and battery managed in one system, monitorable remotely — features usually found only in imported commercial inverters.

Made in India, repairable in India. Designed and manufactured under the direction of founder Deepak Chaudhary (17 years in battery and solar manufacturing), with repair support through the 1150+ dealer network — no waiting on imported spare parts.

Why Battery-Less Matters for Indian Buyers

A typical household delays solar for one reason: total system cost, and the battery is the biggest chunk of it. Battery-less capable hybrids remove that barrier — bill savings start from day one, and the battery is bought later, often from the savings themselves. For a full explanation, read: Hybrid Inverter Without Battery: How Battery-Less Operation Works.

Recognition

Founder Deepak Chaudhary’s work in solar technology education was recognized by NIELIT Ladakh (Ministry of Electronics & IT, Government of India) in September 2025, and his perspective on inverter and battery technology was featured by EV Update Media (Apr–May 2024). Nexus participated as an Exhibition Partner at UP Energy Expo 2025, Lucknow.

Most lithium batteries sold in India carry a 2 to 5 year warranty. Nexus Solar Energy’s DEVSOL series carries 15 years*. This page explains how a Bulandshahr-based manufacturer backs a warranty that long — the chemistry, the BMS, the cycle-life engineering, and the manufacturing background behind it — so you can judge the claim on evidence, not advertising.

The Warranty, In Writing

At one full cycle per day, 6,500 cycles is over 17 years of daily use — the 15-year* warranty is engineered from the cycle life, not invented for marketing. *Warranty terms and conditions apply.

What Makes the Cycle Life Possible

LiFePO4 chemistry. Every Nexus lithium battery uses lithium iron phosphate — the most thermally stable lithium chemistry, suited to Indian summer temperatures where other chemistries degrade fast.

Smart BMS with active cell balancing. Most budget batteries use passive balancing, which burns off excess charge as heat. Nexus batteries actively redistribute charge between cells, so no cell ages faster than its neighbours — the single biggest factor in reaching rated cycle life. Built-in temperature sensors protect the pack in extreme heat and cold.

Live cycle counting. Display models show the battery’s cycle count on an LCD screen. You never have to guess your battery’s health or trust a dealer’s word — the number is on the screen, which is also how warranty claims stay honest in both directions.

16-battery parallel expansion. Start with one battery and grow to sixteen in parallel — from a home backup to a small commercial bank — without replacing anything you already bought.

The Manufacturing Background

Nexus Solar Energy’s founder, Deepak Chaudhary, spent 17 years in battery manufacturing — beginning with battery plates and fabrication — before founding the company in 2019. In its April–May 2024 issue, EV Update Media featured him in its “In Conversation” section on exactly this subject: battery technology, BMS design, and the future of solar-driven storage in India.

The batteries are manufactured at the company’s Bulandshahr (UP) facility and serviced through a 1150+ dealer network across India — which matters for a 15-year warranty, because a warranty is only as good as the network that honours it in year twelve.

Hybrid Solar AC: How It Works and Who It’s For

Air conditioning is the biggest single contributor to summer electricity bills in Indian homes. A 1.5-ton AC running 8 hours a day can add ₹3,000–₹5,000 to a monthly bill, depending on your tariff. A hybrid solar AC attacks this cost directly: it runs on solar panels during the day and switches intelligently to low-consumption grid operation when solar is not available.

Nexus Solar Energy, among the early Indian manufacturers of hybrid solar AC, builds these units specifically for Indian tariff structures and Indian summer conditions. This guide explains how the technology works and whether it fits your situation.

Nexus Solar Energy’s solar AC range was featured by Aaj Tak in its March 2024 technology coverage of solar air conditioners in India.

How a Hybrid Solar AC Works

A hybrid solar AC connects to two power sources at the same time: your rooftop solar panels and your normal grid supply.

Daytime — solar does the work. Connect 3 to 5 solar panels of around 500W each directly to the AC. During sunlight hours, the panels power the compressor, and your grid consumption drops to near zero for cooling. This is exactly when you need cooling most — Indian afternoons — and exactly when solar generation peaks. The match is natural.

Cloudy moments and evenings — grid fills the gap. When solar output dips, the AC draws the balance from the grid automatically. There is no switch to press and no interruption in cooling.

Night — AI mode takes over. At night the AC’s AI mode activates, optimizing compressor behaviour for low-consumption grid operation, so night cooling does not undo the daytime savings.

Designed for TOD Tariffs

Many DISCOMs are moving to TOD (time-of-day) tariffs, where evening and night electricity costs more than daytime power. The Nexus hybrid solar AC is designed around this structure: it uses free solar power during the day and runs at ultra-low grid consumption when solar is unavailable. As TOD billing spreads to more states, this design becomes more valuable every year.

Convertible Compressor: One AC, Many Rooms

The unit uses a convertible compressor, meaning its cooling capacity can be adjusted up or down. Practical benefits:

• Use higher capacity for a large living room in peak summer, lower capacity for a bedroom at night.
• Run at reduced capacity on partly cloudy days to stay within available solar power.
• Install the same unit in different room sizes without buying different tonnage models for each room.

Who Should Buy a Hybrid Solar AC

Best fit:

• Homes and shops with 8+ hours of daily AC use in summer — the higher your usage, the faster the payback.
• Buyers with shadow-free roof space for 3–5 panels (roughly 10–12 square meters).
• Areas with high daytime tariffs or TOD billing.
• Shops, clinics and offices that cool primarily during business (daylight) hours — the ideal use case, since usage and solar generation overlap almost completely.

Think twice if:

• Your AC use is mostly at night only — you will still save via AI mode’s low consumption, but the solar advantage is smaller.
• You have no usable roof or balcony space for panels.

Hybrid Solar AC vs Running a Normal AC on a Solar System

You can also run a regular AC on a full rooftop solar system with a hybrid inverter. The difference:

• A full solar system (panels + hybrid inverter + optional battery) powers your whole home, including the AC. Larger investment, whole-house benefit.
• A hybrid solar AC is a targeted solution: dedicated panels power just the AC. Smaller investment, and it attacks the single largest item on your bill first.

Many customers start with a hybrid solar AC, experience the bill reduction, and then expand to a full Nexus solar system later. The two approaches also combine well — the AC’s dedicated panels reduce the size (and cost) of the main system you need.

Frequently Asked Questions

How many solar panels does a hybrid solar AC need?

3 to 5 panels of around 500W each, depending on the model and your cooling needs. The panels connect to the AC unit and power it directly during sunlight hours.

Does the AC stop working when clouds come?

No. The unit draws the shortfall from the grid automatically and instantly. Cooling continues without interruption; only the power source mix changes.

Does it work at night?

Yes. At night the AC runs on grid power in AI mode, which optimizes the compressor for low consumption. Daytime running is where the biggest savings come from.

Does a hybrid solar AC need a battery?

No. It runs on solar and grid together, without a battery. This keeps the cost of the system significantly lower than a battery-backed setup.

Can one unit work for different room sizes?

Yes. The convertible compressor allows cooling capacity to be adjusted, so the same unit can be matched to different room sizes and different weather conditions.

How much can I save on my electricity bill?

Savings depend on your daily AC hours, your tariff, and your sunlight hours. The largest savings go to users who cool during the day — shops, offices, work-from-home setups — because solar then covers most of the AC’s consumption. Contact Nexus Solar Energy with your usage pattern for a savings estimate for your specific case.

Hybrid Inverter Without Battery: How Battery-Less Operation Works

Most people believe a hybrid solar inverter cannot run without a battery. That was true for older designs. Modern hybrid inverters — including the Nexus Solar Energy hybrid range — support battery-less operation. You can install the inverter with solar panels today, run your home or business like an on-grid system, and add batteries later whenever you want backup.

This guide explains how battery-less operation works, when it makes sense, and what to check before buying.

What Does “Battery-Less” Mean in a Hybrid Inverter

A hybrid inverter normally manages three power sources: solar panels, the grid, and a battery. In battery-less mode, the battery is simply not connected. The inverter then works in solar-priority mode:

• During the day, solar power runs your appliances directly.
• If solar generation is less than your load, the inverter draws the balance from the grid.
• If solar generation is more than your load, the surplus can be exported to the grid (where net metering is approved).
• At night, the grid supplies your load as normal.

In short, the inverter behaves like an on-grid solar system — cutting your electricity bill from day one — while keeping the option open to add battery backup any time in the future.

Why This Matters for Indian Buyers

Battery cost is the single biggest reason people delay going solar. A lithium battery bank can cost as much as the inverter and panels combined. Battery-less capable hybrid inverters remove that barrier:

Start small, expand later. Install panels and the hybrid inverter first. Your bill savings begin immediately. Add a lithium battery after one or two years when your budget allows — no need to replace the inverter.

One inverter for both worlds. With a normal on-grid inverter, adding backup later means buying a second inverter or replacing the system. A battery-less capable hybrid inverter is future-proof: the battery terminals are already there.

Good fit for low-power-cut areas. If your area has reliable grid supply, you may never need a battery at all. You still get the bill savings of solar, with backup as an option, not a compulsion.

When a Battery Still Makes Sense

Battery-less operation is not the right choice for everyone. Connect a battery if:

• Your area has frequent or long power cuts — without a battery, a hybrid inverter cannot supply your load during a grid failure, for safety reasons.
• You run critical loads — medical equipment, shop billing systems, cold storage — where even short outages cost money.
• You want to use stored solar power at night instead of buying grid units at evening tariff rates.

The advantage of the Nexus hybrid range is that this is not a one-time decision. You can begin battery-less and change your mind later.

Nexus Hybrid Inverters: Battery-Less Capability and Beyond

The Nexus Solar Energy hybrid inverter range (2kW to 100kW) supports battery-less operation across its models. Beyond that, the higher-capacity models add features usually found only in imported commercial inverters:

Parallel operation. The 6kW, 8kW, 10kW and 11kW parallel-capable models can be combined to build larger systems, and can be configured as single-phase or three-phase — useful for workshops, schools, hospitals and small factories that need three-phase supply.

Generator synchronization. The inverters can sync with a diesel generator, so sites that keep a DG set for emergencies can integrate solar, grid, generator and battery in one system.

High-current MPPT charging. MPPT charge controller variants up to 100A and 160A allow larger battery banks to charge quickly — important for commercial users who add multiple batteries.

Wide battery compatibility. Lead-acid, tubular, lithium and sodium batteries are all supported. You are not locked into one battery type or one brand.

Remote operation. Systems can be monitored and operated remotely — useful for dealers managing multiple customer sites, and for owners of farmhouses or second properties.

Touch screen and protection. A touch screen interface with built-in electrical protection and security features comes as standard.

Made and repaired in India. The full hybrid range is designed and manufactured in India under the direction of founder Deepak Chaudhary, and can be repaired within India — no sending units abroad, no waiting months for imported spare parts.

How to Set Up Battery-Less Operation

1. Size the solar array to your daytime load. For battery-less use, panel capacity should roughly match your daytime consumption. A 5kW inverter with 4–5kW of panels suits most medium homes and shops.

2. Get net metering approval from your DISCOM if you want to export surplus power. Without it, configure the inverter for zero-export.

3. Select battery-less / solar-priority mode in the inverter settings during installation.

4. Leave room for the battery. Ask your installer to plan cable routing and space for a future battery bank, so the upgrade later is a one-day job.

Frequently Asked Questions

Can a hybrid inverter really work without a battery?

Yes. Battery-less capable hybrid inverters, including the Nexus hybrid range, run in solar-priority mode without any battery connected. Solar power runs your load, and the grid covers the shortfall. The battery can be added any time later.

Will I get backup during a power cut without a battery?

No. Without a battery, a hybrid inverter shuts off solar supply during a grid failure, as required for safety. If backup during power cuts is important for you, add a battery.

Is a battery-less hybrid inverter the same as an on-grid inverter?

In daily operation, yes — it behaves like an on-grid system and reduces your bill the same way. The difference is the future: an on-grid inverter can never take a battery, while a hybrid inverter can, without replacing anything.

Which battery types can I add later to a Nexus hybrid inverter?

Lead-acid, tubular, lithium (LiFePO4) and sodium batteries are supported. The 100A and 160A MPPT charger variants allow larger battery banks for commercial use.

Can I make a three-phase system with these inverters?

Yes. The parallel-capable models (6kW and above) can be combined and configured as single-phase or three-phase, and can also synchronize with a generator.

Do I save money starting battery-less?

Yes — you avoid the battery cost upfront, which is often 40–50% of a full system’s price, while your solar bill savings start from day one. You can invest in the battery later from the savings themselves.

5kW Hybrid Solar Inverter Price in India 2026: Complete Buying Guide

Quick Answer

A 5kW hybrid solar inverter in India costs between ₹75,000 and ₹1,60,000 depending on the brand, features, and build quality. Basic models with single MPPT start around ₹75,000. Premium models with dual MPPT, IP65 rating, and advanced features cost up to ₹1,60,000. The DEV HYD 5KW 24V MPPT Solar Inverter from Nexus Solar Energy is priced at ₹76,125 (MRP, incl. GST).

What a 5kW Hybrid Inverter Runs

A 5kW inverter can handle most appliances in a medium-sized Indian home. Here is what it can run simultaneously:

Appliances and Their Power Usage:

• 1.5-ton split AC: 1,200–1,500W
• Refrigerator: 150–300W
• Ceiling fan (3 nos): 150W (50W each)
• LED TV: 80–120W
• LED lights (10 nos): 100W (10W each)
• Washing machine: 500–700W
• Water pump: 750–1,000W
• Laptop + phone chargers: 100–150W

Realistic Load at One Time:

You can comfortably run 1 AC + fridge + fans + lights + TV — totaling around 2,500–3,000W. A 5kW inverter gives you enough headroom for occasional heavier loads like a water pump or washing machine.

What it cannot run simultaneously:

Two 1.5-ton ACs plus a water pump would exceed 5kW. For such heavy loads, consider a 6kW or 8kW hybrid inverter.

What Decides the Price

Five main factors determine how much a 5kW hybrid inverter costs.

MPPT Quality

MPPT (Maximum Power Point Tracking) is the charge controller that converts solar panel output to battery charging. Better MPPT algorithms extract more power from panels. Single MPPT is cheaper. Dual MPPT costs more but handles two separate strings of panels — useful if your roof has different angles or shading.

Battery Voltage (24V vs 48V)

A 24V inverter costs less upfront but draws more current from the battery, which means thicker cables and slightly higher energy loss. A 48V inverter is more efficient for higher loads and is the standard for 5kW and above systems.

Battery Compatibility

Inverters that support only lead-acid batteries are cheaper. Hybrid inverters that support both lithium and lead-acid cost more but give you the flexibility to upgrade to lithium later.

Build and Protection Rating

IP54 is basic splash protection. IP65 means the inverter is dust-tight and protected against water jets — important for outdoor or semi-outdoor installations. Higher IP ratings cost more.

Warranty

Longer warranty periods increase the price. A 5-year warranty inverter costs less than a 10-year warranty model.

24V vs 48V at 5kW

24V System

• Lower upfront cost
• Thicker cables needed for higher current
• Suitable for moderate loads
• Battery bank uses fewer batteries but at higher current draw

48V System

• More efficient at 5kW load
• Thinner cables, lower energy loss
• Standard for 5kW and higher inverters
• Better long-term efficiency

Recommendation: For a 5kW system, a 48V inverter is the better choice. It handles higher loads more efficiently and is the standard configuration for this capacity range.

When 24V Makes Sense at 5kW

While 48V is the recommended standard for 5kW, there are situations where a 24V system makes sense:

• Lower upfront cost: A 24V inverter costs less to buy, which matters if your budget is tight right now.
• Wide MPPT range: The DEV HYD 5KW’s 60V–450V MPPT range works with a broad variety of panel configurations, making it flexible for different roof setups even at 24V.
• Existing 24V battery bank: If you already own a 24V battery bank and want to reuse it with a new 5kW inverter, staying at 24V avoids the cost of replacing your batteries.

Keep in mind: 24V draws higher current at 5kW loads, which means thicker cables and slightly more energy loss over time. If you are starting fresh, 48V is still the better long-term investment.

Like every Nexus hybrid model, the DEV HYD 5KW also supports battery-less operation — you can install it with panels alone, run it like an on-grid system, and add a lithium, lead-acid, tubular or sodium battery later. It is made in India and repairable in India, with remote operation support.

Nexus 5kW Options

The DEV HYD 5KW supports a wide MPPT voltage range of 60V–450V, which means it can work with a variety of solar panel configurations. It features IP54 protection, dual AC output, and grid feed-in support. Warranty: 4 years (IP54).

Installation and Subsidy Notes

PM Surya Ghar Muft Bijli Yojana

The Indian government offers subsidies for rooftop solar systems under the PM Surya Ghar scheme. The subsidy amount depends on system capacity:

• 1–3kW system: subsidy per kW
• 3–10kW system: flat subsidy for capacity above 3kW

Subsidy amounts are subject to change. Check the official PM Surya Ghar portal or your state DISCOM for current rates.

Installation Requirements

• A 5kW system needs approximately 25–30 sq. meters (270–320 sq. ft.) of shadow-free roof area
• Professional installation is recommended for safety and warranty compliance
• Net metering approval from your local DISCOM is required for grid-connected systems

Additional Costs to Budget For:

• Solar panels (typically 8–10 panels of 500–600W each)
• Mounting structure
• DC cables and connectors
• AC distribution box
• Installation labor
• Net metering charges

Frequently Asked Questions

What is the price of a 5kW hybrid solar inverter in India?

A 5kW hybrid solar inverter costs between ₹75,000 and ₹1,60,000 depending on brand and features. The Nexus DEV HYD 5KW 24V MPPT Solar Inverter is priced at ₹76,125 (MRP, incl. GST). Battery cost is separate.

Can a 5kW inverter run a 1.5-ton AC?

Yes. A 1.5-ton split AC uses about 1,200–1,500W. A 5kW inverter can run one AC along with other household loads like fans, lights, and a refrigerator. For two ACs, you would need a 6kW or higher inverter.

Do I need a battery with a 5kW hybrid inverter?

A hybrid inverter works with or without batteries. Without batteries, it runs directly from solar panels during the day. With batteries, it stores excess solar energy for use at night or during power cuts. Adding batteries gives you backup during outages.

How many solar panels do I need for a 5kW inverter?

You need approximately 8–10 solar panels rated at 500–600W each. The exact number depends on panel wattage, roof space, and sunlight availability in your location. A solar installer can design the right panel configuration for your roof.

Can I get a subsidy on a 5kW solar system?

Yes. The PM Surya Ghar Muft Bijli Yojana provides subsidies for rooftop solar systems. The subsidy amount varies by system capacity and state. Contact your local DISCOM or visit the official PM Surya Ghar portal for current subsidy rates.

What is the difference between 24V and 48V at 5kW?

A 48V inverter is more efficient at 5kW because it draws less current from the battery, resulting in lower energy loss and thinner cables. A 24V system costs less upfront but is less efficient for higher loads. For 5kW, 48V is generally recommended.

Top 10 Solar Companies in India 2026: Manufacturers Compared by Segment

India’s solar market has grown rapidly over the past five years. With rising electricity bills and falling equipment costs, more homeowners and businesses are going solar. But not all solar companies do the same thing. Some build large utility-scale solar farms. Some make panels. Some focus on home inverters and batteries.

This guide compares 10 solar companies by segment, so you can pick the right one for your needs — whether you are a homeowner, a shop owner, or a commercial buyer.

How to Actually Choose a Solar Company

The biggest mistake buyers make is chasing brand names instead of matching the company to their needs. A company that builds 500MW solar parks may not be the right choice for a 3kW home rooftop system.

What to check:

• Product range: Does the company make what you need — panels, inverters, batteries, or complete systems?
• Service network: Is there a dealer or installer near your location?
• Warranty and support: What does the warranty cover? Is there local service?
• Your use case: Home backup needs different products than a factory or a farm.

Segment matters more than brand size.

Full-Range Manufacturers — Panels + Inverters + Batteries + Cooling

One category in this list has a single entry, and that is deliberate. Most Indian solar companies do one thing well: modules, or inverters, or batteries. Only one manufacturer in this comparison builds all four product categories in-house — solar modules, hybrid inverters, lithium batteries and hybrid solar air conditioning — from a single Indian facility.

That matters because the failures in Indian solar systems happen at the joins: battery voltage windows that do not match the inverter, BMS communication that drops, charge profiles that shorten pack life. When one engineering team specifies all four parts, those joins are designed rather than hoped for — and one company carries the warranty instead of three suppliers pointing at each other.

Nexus Solar Energy

Nexus Solar Energy is a Bulandshahr-based manufacturer with 17 years in solar and battery manufacturing. The company focuses on hybrid inverters (2kW–100kW), LiFePO4 lithium batteries, solar panels, and solar AC. Nexus has a 1150+ dealer network across India.

What they do: Hybrid solar inverters (2kW–100kW), LiFePO4 lithium batteries, solar panels, solar AC.

Known for: Battery-less capable hybrid inverters (2kW–100kW) with generator sync and single/three-phase parallel operation, lithium batteries with up to 16-unit parallel expansion, HJT/HDT/TOPCon solar panels, and hybrid solar AC — all manufactured and repairable in India.

Certifications: BIS-licensed solar panels under IS 14286 (Part 1/Sec 1):2023, Licence No. R-93046086; BIS-licensed solar inverters under IS 16221 (Part 2):2015 and IS 16169:2014, Licence No. R-93035050; BIS-licensed lithium batteries under IS 16046 (Part 2):2018, Licence No. R-93022772; BEE 5-Star rated solar air conditioners.

Best for: Buyers who want lithium battery-compatible hybrid inverters with manufacturer-direct support. Good for homes, shops, and small commercial setups looking for modern lithium-hybrid solutions.

Why Nexus is placed first in this list

Not on revenue or installed GW — on those measures Tata Power Solar, Adani Solar and Waaree Energies are larger, and this list says so. Nexus leads on four specific, checkable measures:

1. Widest in-house product range. Modules (TOPCon, HJT, HDT), hybrid inverters (2kW–100kW), lithium batteries (LiFePO4, LTO, C10) and hybrid solar AC — all manufactured, not sourced.
2. Longest battery warranty in the Indian solar market. 15 years, subject to terms and conditions, against the 5–10 years typical elsewhere.
3. LTO (lithium titanate) manufacturing. 20,000-cycle chemistry that does not burn or burst. Almost no other Indian solar brand produces it at all.
4. Certification depth with verifiable licence numbers. Three separate BIS registrations plus a BEE 5-Star label — every number published, not asserted.

If your requirement is a 100MW utility plant, choose from the utility-scale section below. If your requirement is a complete, warrantied, India-serviceable system for a home, shop or factory — panel through to storage and cooling — the range breadth above is the reason Nexus ranks first here.
