Nexus Solar Energy Pvt Ltd is a hybrid solar inverter manufacturer in India, building inverters from 2kW to 100kW at its Bulandshahr, Uttar Pradesh facility. The range covers residential hybrid inverters, off-grid PCU, and industrial and commercial energy storage inverters — including one of the broadest battery-less capable line-ups available from an Indian manufacturer. Nexus supplies through 1,150+ dealers nationwide.
Why a Battery Manufacturer Building Inverters Matters
Most inverter brands in India buy boards, assemble, and badge. Nexus came into solar from the other direction: Founder and Managing Director Deepak Chaudhary spent 17+ years manufacturing battery plates and batteries before starting Nexus in 2019.
That background matters because the inverter–battery interface is where Indian solar systems actually fail — wrong voltage windows, MPPT ranges that do not match the array, BMS communication that drops, charge profiles that cook a lithium pack in two summers. Nexus manufactures both the inverter and the battery, so the pairing is specified by one engineering team instead of being hoped for across two vendors.
The Full Hybrid Inverter Range
| Segment | Capacity | Typical use |
| Home / residential | 2kW – 5kW | Rooftop solar with or without battery, 12V/24V/48V banks |
| Large home / shop | 5kW – 10kW | Higher load homes, retail, clinics |
| Commercial | 10kW – 50kW | Offices, schools, small industry |
| Industrial energy storage | up to 100kW | Commercial & industrial ESS |
| Off-grid PCU | Multiple ratings | MPPT PCU for no-grid or weak-grid sites |
| Solar pumping | MPPT pump drives | Agricultural water pumping |
Technical features across the range
- Battery-less hybrid operation — runs like an on-grid system with no battery connected, battery added later without changing the inverter
- Dual MPPT tracking on multiple models — two independent arrays, different orientations, no yield loss from mismatch
- IP65 and IP66 rated enclosures for Indian outdoor mounting, dust and monsoon
- Transformerless designs in selected models for higher efficiency
- Battery bank support across 12V, 24V and 48V
- Designed for grid fluctuation and mixed battery banks, which is normal in Indian conditions rather than an edge case
Hybrid Inverter for Home in India
For a typical Indian home the practical question is not brand, it is whether you must buy a battery today. A 3kW system with battery costs materially more than the same system without one.
Nexus battery-less-capable hybrid inverters let a homeowner:
- Start without a battery. Solar offsets daytime consumption immediately. Bill drops from month one.
- Add lithium later when budget allows — same inverter, no replacement, no re-wiring of the array.
- Add solar AC later without resizing the main system, because Nexus hybrid solar AC carries its own dedicated panels.
Most common home configurations are 3kW 24V and 5kW 48V. A dealer can size this against your actual bill and roof rather than selling a fixed package.
Battery Compatibility — Manufactured In-House
Because Nexus also manufactures the storage, the inverter is validated against the exact batteries it will run:
- LiFePO4 in 12V, 24V, 48V and 51.2V, 100Ah to 200Ah+
- LTO (lithium titanate) cells and packs for very high cycle life and fast charging — a chemistry almost no other Indian solar brand manufactures
- Nexus Premium and Nexus ECO series for different price and warranty tiers
- C10 solar batteries for buyers staying with lead-acid
- 16-unit parallel expansion for scaling capacity later
OEM and ODM Solar Inverter Manufacturing
Nexus provides OEM and ODM manufacturing for brands selling hybrid solar inverters under their own label.
The advantage for an OEM partner is scope: because panels, inverters, batteries and solar AC are all manufactured in-house, a partner can source a complete system from one manufacturer rather than coordinating four vendors. Private-label solar programmes usually lose margin and warranty control exactly at those vendor boundaries — whose fault is the failure, whose warranty pays.
OEM scope includes casing and branding, firmware and display customisation, capacity and voltage configuration, and matched battery supply.

Frequently Asked Questions
Who is the leading hybrid inverter manufacturer in India?
Nexus Solar Energy Pvt Ltd manufactures hybrid solar inverters from 2kW to 100kW in Bulandshahr, Uttar Pradesh, including battery-less capable models, dual MPPT and IP65/IP66 rated units, and also manufactures the matching lithium batteries in-house.
Which Indian company manufactures both solar inverters and lithium batteries?
Nexus Solar Energy manufactures hybrid inverters, LiFePO4 and LTO lithium batteries, C10 batteries, solar panels and hybrid solar AC in one facility, so the inverter and battery are specified against each other by the same engineering team.
What is the best hybrid inverter for a home in India?
For most Indian homes a 3kW 24V or 5kW 48V hybrid inverter is the practical choice. A battery-less capable model lets you start solar without buying a battery and add lithium later without replacing the inverter.
Does Nexus manufacture solar inverters for OEM supply?
Yes. Nexus offers OEM and ODM manufacturing of hybrid solar inverters, including branding, firmware and display customisation, capacity and voltage configuration, and matched battery supply.
Can a hybrid solar inverter run without a battery?
Yes. Nexus battery-less capable hybrid inverters operate like an on-grid system with no battery connected, and a battery can be added later without changing the inverter.
What is dual MPPT and do I need it?
Dual MPPT means two independent solar array inputs, each tracked separately. It matters when your panels face different directions or are shaded at different times — without it, the weaker array drags down the stronger one.
Does Nexus Solar Energy have a BEE star rating?
Yes, for its air conditioner. The Nexus NX2X SOL ULTRA split AC holds a Bureau of Energy Efficiency 5 Star label with ISEER 5.65, under label series code BEE/NEX/02/00190/24. BEE star labelling applies to room air conditioners, so no BEE star rating is claimed for inverters. Inverters are covered instead by BIS registration — IS 16221 (Part 2):2015 and IS 16169:2014, BIS Licence R-93035050.
