Every hybrid inverter Nexus Solar Energy makes — from 2kW to 15kW — 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 15kW 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.

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.
Frequently Asked Questions
Can Nexus hybrid inverters really work without a battery?
Yes — every model in the 2kW–15kW range supports battery-less, solar-priority operation, functioning like an on-grid inverter until a battery is added.
Which battery types do Nexus hybrid inverters support?
Lead-acid, tubular, lithium (LiFePO4) and sodium.
What warranty do Nexus hybrid inverters carry?
By protection class: IP21 models 2 years, IP54 models 4 years, IP65/IP66 models 5 years.
Can I build a three-phase system?
Yes — the parallel-capable models (6kW–11kW) can be configured single-phase or three-phase and can synchronize with a generator.
