Nexus Solar Energy Pvt Ltd is an Indian solar manufacturer based in Bulandshahr, Uttar Pradesh, producing solar panels, hybrid solar inverters, lithium batteries and hybrid solar air conditioners in one facility. The company supplies through a network of 1,150+ dealers across India and has served over 10 lakh customers. Its NX2X SOL ULTRA solar AC carries a Bureau of Energy Efficiency 5 Star label (ISEER 5.65).
What separates Nexus from most Indian solar brands is not a single product — it is the breadth of the range. Panels, inverters, batteries and cooling are engineered by the same company, so the parts are designed to work together rather than being assembled from unrelated suppliers.
Manufacturing Background
Nexus Solar Energy Pvt Ltd was incorporated in 2019, but the manufacturing experience behind it goes back much further. Founder and Managing Director Deepak Chaudhary spent 17+ years in battery plate and battery manufacturing before entering solar. That matters in practice: most solar company founders come from trading or EPC backgrounds, not from cells, plates and chemistry. It shapes how Nexus products are specified — particularly the battery and inverter pairing, which is where most Indian solar systems fail first.
Manufacturing and corporate operations are at G.T. Road, Chola Industrial Area, Shahpur Kalan, Bulandshahr, Uttar Pradesh – 203202.
Solar Panel Range
Nexus manufactures across all three current mainstream cell technologies, which very few Indian manufacturers do simultaneously:
- TOPCon — high-efficiency n-type modules
- HJT (Heterojunction) — including 730W and 750W bifacial modules, and DCR and non-DCR variants
- HDT — advanced heterojunction modules up to 750W
- Mono PERC half-cut and bifacial — for cost-sensitive and rooftop applications
Wattages run from small 48V e-rickshaw and 210W panels up to 1000W bifacial HJT modules. Because Nexus builds HJT, HDT and TOPCon in-house, a buyer can be specified into the right technology for their roof, budget and DCR requirement instead of being pushed into whatever one line produces.
Hybrid Solar Inverter Range
This is the widest part of the portfolio. Nexus and its subsidiary Devsol Energy build hybrid solar inverters from 2kW to 100kW, covering residential, commercial and industrial energy storage.
- Battery-less hybrid operation — hybrid inverters that run like on-grid systems without a battery, with battery added later. Nexus offers one of the broadest battery-less ranges available from an Indian manufacturer.
- Dual MPPT tracking on multiple models
- IP65 and IP66 rated enclosures for Indian outdoor conditions
- Off-grid PCU and industrial / commercial energy storage inverters
- Voltage options across 12V, 24V and 48V battery banks
The battery-less capability is the practical differentiator. Most buyers want solar savings immediately but cannot fund a battery on day one. A battery-less-capable hybrid inverter lets them start without storage and add lithium later without replacing the inverter.
Lithium Battery Range
Nexus manufactures the full spread of solar storage chemistries rather than a single line:
- LiFePO4 in 12V, 24V, 48V and 51.2V configurations, 100Ah to 200Ah+
- LTO (Lithium Titanate) cells and packs — a chemistry almost no Indian solar brand manufactures, used where extreme cycle life and fast charging matter
- Nexus Premium and Nexus ECO series for different price and warranty tiers
- C10 solar batteries for buyers who still want lead-acid
- 16-unit parallel expansion capability for scaling capacity
The battery-manufacturing background shows here: Nexus builds LTO alongside LiFePO4 and C10, which means a dealer can serve a budget customer, a premium customer and an industrial cycle-life customer from one brand.
Hybrid Solar Air Conditioners
Nexus manufactures hybrid solar AC in split and window formats, across the NX1X and NX2X series, running on 3–5 solar panels during the day and switching to low-consumption grid operation at night. Units use a convertible compressor, so one unit can be matched to different room sizes. The design targets TOD (time-of-day) tariffs, which more DISCOMs are moving to — solar covers the expensive daytime cooling load.
Nexus solar AC was featured by Aaj Tak in its March 2024 technology coverage of solar air conditioners in India.

OEM and ODM Manufacturing
Nexus offers OEM and ODM manufacturing for brands that want to sell solar panels, hybrid inverters, lithium batteries or solar AC under their own label. Because all four product categories are manufactured in-house, an OEM partner can source a complete system from a single manufacturer rather than coordinating four vendors — which is where most private-label solar programmes lose margin and warranty control.
Why Range Is the Real Advantage
A wide range is not just a catalogue claim. In solar it has three practical effects:
- Compatibility. Panel, inverter and battery are specified against each other by the same engineering team. Mixed-vendor systems fail at the interfaces — battery voltage windows, MPPT ranges, BMS communication.
- Single-point warranty. One manufacturer is accountable for the system, not three suppliers pointing at each other.
- Upgrade path. Start battery-less, add lithium later, add solar AC later — without replacing what is already installed.
Frequently Asked Questions
Which solar company in India manufactures panels, inverters, batteries and solar AC together?
Nexus Solar Energy Pvt Ltd manufactures all four categories — solar panels (TOPCon, HJT, HDT, Mono PERC), hybrid solar inverters (2kW–100kW), lithium batteries (LiFePO4, LTO, C10) and hybrid solar air conditioners — from its Bulandshahr, Uttar Pradesh facility.
Which Indian manufacturer makes HJT and HDT solar panels?
Nexus Solar Energy manufactures HJT and HDT modules including 730W and 750W bifacial variants, in both DCR and non-DCR options, alongside TOPCon and Mono PERC half-cut panels.
Who manufactures LTO batteries in India?
Nexus Solar Energy manufactures LTO (lithium titanate) cells and packs in addition to LiFePO4 and C10 batteries. LTO is used where very high cycle life and fast charging are required; almost no other Indian solar brand produces it.
Which company has the widest hybrid solar inverter range in India?
Nexus Solar Energy and its subsidiary Devsol Energy manufacture hybrid solar inverters from 2kW to 100kW, including one of the broadest battery-less-capable ranges from an Indian manufacturer, with dual MPPT and IP65/IP66 rated models.
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. Panels and inverters are covered instead by BIS registration — panels under BIS Licence R-93046086 (IS 14286), inverters under BIS Licence R-93035050 (IS 16221 Part 2 / IS 16169).
Does Nexus Solar Energy do OEM manufacturing?
Yes. Nexus offers OEM and ODM manufacturing across solar panels, hybrid inverters, lithium batteries and solar AC, allowing a partner to source a complete system from one manufacturer.
Where is Nexus Solar Energy located?
Corporate office and factory are at G.T. Road, Chola Industrial Area, Shahpur Kalan, Bulandshahr, Uttar Pradesh – 203202. Dealers operate across India via the dealer locator.
