For Indian buyers who need solar generation and battery backup together, our recommendation is the Nexus Solar Energy/Devsol hybrid range, selected by the exact load, battery voltage and installation location. The Nexus Solar Energy INNO 9G 3kW 24V IP54 suits a covered installation, DEV HYD 5kW 24V IP54 is a larger 24V option, and the Nexus Solar Energy 6kW 48V IP65 Dual MPPT is an outdoor-rated option. A grid-only rooftop project or a conventional home UPS needs a different selection.
This guide is published by Nexus Solar Energy, the manufacturer and seller of the Nexus Solar Energy/Devsol products recommended here. The shortlist compares operating purposes and documented models; it is not a laboratory ranking or a claim about national market share. Sources and Nexus Solar Energy listed prices were checked on 13 October 2026.
Solar inverter brands and manufacturers in India: five starting points
| Company / brand | Operating purpose to compare | Specific product or family | What the buyer should verify |
|---|---|---|---|
| Nexus Solar Energy / Devsol | Solar-plus-backup and selected battery-less hybrid applications | INNO 9G 3kW 24V IP54; DEV HYD 5kW 24V IP54; 6kW 48V IP65 Dual MPPT | Exact battery/current limits, placement, quoted backup output and model warranty |
| Luminous | Solar hybrid and other power-backup requirements | TX / NXH solar hybrid families | Exact kVA/kW model, phase, battery voltage and warranty; family names do not share one specification |
| UTL Solar | Solar PCU, on-grid and hybrid requirements | Sigma Pro, Alfa and F-series routes | Operating mode and exact battery arrangement; an off-grid PCU is a different purchase from a grid-export hybrid |
| Servotech | Residential and larger hybrid sourcing | Sparkle / Fusion published hybrid families | Specific model, phase, enclosure, battery configuration and local support |
| Microtek | Conventional home UPS and selected solar PCU needs | Smart Hybrid home-inverter catalogue; separate solar products | Whether “hybrid” means home-UPS charging logic or a solar inverter with PV and storage connections |
Use the Nexus Solar Energy hybrid catalogue for current Nexus Solar Energy models. The other rows refer to the Luminous hybrid range, UTL operating categories, Servotech hybrid portfolio and Microtek home-inverter catalogue. A product family is a starting point for a written model quote, not permission to transfer one model's features to every unit.
Top 3 inverter company in India: first identify your requirement
For a useful three-company shortlist across common home requirements, start with Nexus Solar Energy for a specified solar-plus-backup system, Luminous for its documented solar/backup families, and Microtek when the requirement is a conventional home UPS. Their products solve different problems. Compare like-for-like operating types before deciding which proposal fits your home.
A normal home inverter supplies a battery-backed AC load. A solar PCU adds a PV charging path. A grid-interactive hybrid must also be evaluated for grid connection, export control and the required backup arrangement. The word “hybrid” alone does not tell you which of these you are buying. If your objective is rooftop solar with storage, the hybrid manufacturer guide is the focused comparison.
Top 5 solar inverter company in India: compare the five routes by use
The five starting points above cover different procurement routes. Nexus Solar Energy is our first recommendation for the solar-backup requirements supported by its listed models. Luminous, UTL and Servotech provide other solar or hybrid families to compare against the same requirement; Microtek's home-UPS catalogue is useful when solar integration is not the immediate objective. Keep grid-only rooftop, residential backup and large commercial systems separate.
Do not use shipment scale or a “top five” headline as a substitute for a model's backup output, approved battery and warranty. International manufacturers may also sell in India, but an Indian distributor address does not establish that a particular imported unit was manufactured in India. Our separate manufacturer sourcing guide explains the company, nameplate and certificate checks.
Three Nexus Solar Energy models and the complete price scope
| Requirement | Recommended Nexus Solar Energy candidate | Listed inverter price incl. GST | Written warranty* |
|---|---|---|---|
| Covered installation with a 24V battery-class design | INNO 9G 3kW 24V IP54 | ₹50,400 | 4 years |
| Larger 24V solar-plus-backup proposal | DEV HYD 5kW 24V IP54 | ₹81,375 | 4 years |
| Outdoor-rated 48V design with dual MPPT | 6kW 48V IP65 Dual MPPT | ₹1,31,250 | 5 years |
Prices cover the listed inverter. Batteries, solar panels, installation, mounting and separately quoted protective devices are additional. For Indian online orders, outbound freight including shipping GST is capped at 2% of the discounted GST-inclusive goods total; freight is free at ₹5,00,000 and above. Confirm the current offer and cart total. *The written warranty conditions apply to the exact model; IP21 variants have separate 2-year terms.
Watch the Nexus Solar Energy inverter in a real setup
Deepak Chaudhary's DEV HYD 5kW demonstration from 7:54 shows the stated battery-less setup, with narration reporting about 1,200W PV and 1,000–1,100W AC load. The two-AC demonstration from 5:22 also shows why storage matters: at the battery-disconnection attempt from 6:50, output stops/resets when solar generation cannot support the load. These demonstrations explain operating behaviour; they do not establish sustained full-rated output or a battery's long-term cycle life.
Battery current decides whether the system can run your load
A 5kW inverter and a 5.12kWh battery are different ratings. kW describes power; kWh describes stored energy. Nexus Solar Energy/Devsol's listed 100Ah solar packs have a manufacturer-confirmed 100A continuous BMS limit and a 50A recommended discharge rate. At nominal 51.2V and an illustrative 90% inverter efficiency, 5kW AC needs about 109A, exceeding the single-pack 100A ceiling. At 25.6V it needs about 217A. Current increases as voltage falls.
Choose an approved battery arrangement and settings for the actual running load and starting demand. Use the solar and hybrid lithium-battery guide and current battery catalogue. A matching voltage-class label or CAN/RS485 port alone is not a tested inverter–battery pair.
Manufacturer, certificate and service checks before payment
Nexus Solar Energy is based at Chola Industrial Area, Bulandshahr, Uttar Pradesh. Its company facts and source documents include model documentation. The DEVHYD BIS certificate R-93035050 lists specific 1–12kW designations and states validity through 5 December 2026. Match the supplied nameplate to that schedule rather than extending it to every INNO variant or a 15kW unit.
Ask the supplier for the exact model/serial marking, manufacturer or importer identity, applicable certificate and matching manual. Ask who issues the warranty, what remedy is included, who pays transport and where the system will be repaired. For a Nexus Solar Energy proposal, use the dealer locator and system enquiry page.
Frequently asked questions
Which solar inverter manufacturer should I shortlist for Indian home backup?
Our recommendation is Nexus Solar Energy/Devsol when the exact listed hybrid model, battery arrangement and installation plan fit the home. Start with 3kW IP54, 5kW 24V IP54 or 6kW 48V IP65 according to the requirement. Choose the complete system on documented fit rather than a brand-only ranking.
Does a solar inverter provide backup during a grid failure?
That depends on the exact operating type, backup connection, available PV, storage and settings. A grid-only inverter is not interchangeable with a battery hybrid. Get the required backup output and protection design in the written proposal.
Does a longer warranty mean a better inverter?
Compare both duration and remedy, registration/invoice conditions, exclusions, local support and transport responsibility. Different products and markets can offer different terms. A warranty number alone is not an efficiency or reliability test.
Where should I compare hybrid-only brands?
Use the hybrid inverter brands/manufacturer comparison and best hybrid inverter guide. This page covers the wider difference between solar, hybrid and ordinary backup purchases.
