Every Indian factory, hospital and housing society knows the same tangle: a separate inverter here, a room full of batteries there, a solar controller on another wall, and a diesel generator rumbling outside for good measure. A Hyderabad deep-tech company has spent years asking why all of that cannot simply be one intelligent box — and its answer, PuREPower, now stretches from a flat’s balcony wall to a five-megawatt-hour container for the grid itself.
PURE Energy — PUR Energy Limited, incubated at IIT Hyderabad — began incubating PuREPower at the institute in 2018 and launched the range in March 2025. The idea is disarmingly simple: instead of juggling three or four separate products, a customer gets one unified system that combines a high-performance lithium battery, a hybrid solar inverter, UPS functionality and smart AI, all managed through one app and one warranty.

One box, from a home to a factory floor
PuREPower Home covers the whole residential ladder, from a 3 kVA/kW/kWh unit for a compact city flat to a 20 kVA/kW/kWh system for a large villa running several air conditioners, a geyser and even a lift. The company says the home systems deliver 97 per cent round-trip efficiency, twice the surge-load capability of a conventional inverter setup, and a life of more than ten years — all in a compact, wall-mounted unit that replaces the clutter of a separate battery room.
The commercial range scales the same philosophy up. Modular systems of 30, 60 and 120 kWh serve shops, clinics, offices, hotels and factories, and the newest arrival, PuREPower 120.0, was unveiled on 22 August 2026 at PURE Energy’s BESS Workshop 2026 at IIT Hyderabad, before an audience of more than 500 people from corporate, EPC and technology communities across India. The company positions PuREPower 120.0 as India’s first all-in-one integrated battery storage product for commercial and industrial use, built to replace diesel generators of 150 kVA and above. It brings together solar charging, advanced lithium-ion storage, intelligent battery management with predictive AI, remote monitoring with Cloud AI, and Time-of-Day, Time-of-Use and diesel-generator synchronisation features into a single unified system.

The intelligence inside the cabinet
What makes PuREPower more than a bigger battery is the company’s X Platform 3.0. The company says predictive AI watches every system remotely, flagging issues before they become outages, scheduling maintenance proactively and automating day-to-day operation — so downtime shrinks and performance stays high without a technician on site. That intelligence, the company says, draws on learnings from more than 100,000 electric-vehicle battery units, a pedigree PURE carries over from its PURE EV two-wheeler business.
Thermal safety gets the same engineering attention. PuREPower uses the company’s patented Nano-PCM cooling, combined with convection cooling on the commercial range and liquid cooling on the grid-scale system, to keep cells in their comfort zone even through Indian summers. Alongside the 120.0 launch, the company also unveiled new patented technologies it plans to bring into its products in mid-FY28, including high-voltage 1000V/1500V battery management, advanced solid-state battery chemistry and gallium-nitride-based inverter topology for data-centre and medical applications.
Built in India, for India’s grid
At the top of the range sits PuREPower Grid: a containerised system of up to 5 MWh, built for discoms, large industries and electric-vehicle charging aggregators, to steady the grid, shave peak loads and soak up renewable power when it is abundant. The company says grid-scale units have already attracted interest from 20 EPC firms representing more than 5 GWh of projects, and it plans to invest Rs 400 crore to scale production capacity to 2.5 GWh, develop solid-state batteries and expand globally.
The Indian engineering runs deep. The company says 67 per cent of components are locally sourced, that it has filed more than 130 intellectual-property applications, and that its integrated design delivers costs around 50 per cent lower than global counterparts. PURE Energy was founded by Dr Nishanth Dongari and Rohit Vadera, who serves as chief executive, and the company describes itself as engineering-led, with a strong focus on indigenous research, patent filings and technology commercialisation.
India’s storage build-out is only just beginning — a workshop session at the August launch put the market at 470 GWh over the next six years. If that future arrives, it will need storage that is as easy to buy, install and run as any other appliance. PURE Energy’s bet is that the winning battery for India will not be a room full of boxes and wires, but a single, intelligent cabinet that quietly keeps the lights on — at home, at work, and across the grid.
