A battery can store electricity, but it cannot connect to the grid on its own. The grid runs on alternating current (AC), while batteries use direct current (DC). A converter is needed between the two to change the power in both directions.
Much of this equipment, including the components used to make it, is imported, says Abhay Adya, Founder and CEO of Enerzolve Smart Technologies. In 2025, he founded the Bengaluru-based startup to design and manufacture more of it in India.
Adya holds a degree in electrical and electronics engineering from BVB College, Hubli, and spent six years at L&T in business development across India, Doha, and Nairobi. He later worked on mergers and acquisitions at Adani Transmission before becoming Regional Sales Head at Sterlite Power.
In 2020, he joined Zetwerk as Vice President and Business Head for Energy Transition. Anupam Kumar Bhatt, who managed operations under Adya at Zetwerk, joined him as Co-founder after a stint at Rivexa.
Connecting batteries to the grid
Enerzolve operates in two areas: power electronics and instruments.
Its main power electronics product is a power conversion system, a two-way inverter that connects the grid to a battery energy storage system. When charging the battery, it converts alternating current from the grid into direct current. When discharging, it converts the stored power back into alternating current and sends it to the grid.
The systems range from 30 kW to 2.5 MW and use high-frequency magnetics, coils and cores that handle power inside the unit, and silicon carbide power chips. Operating at higher frequencies allows the components to be smaller. Adya says the company’s 2.5 MW unit is designed to weigh about two tonnes.
According to Adya, the system is ready and is undergoing testing and certification. Enerzolve has also filed patents in India and the United States for some of its products.
Its second product, still under development, is a solid-state transformer. Unlike conventional transformers that use an iron core, it relies on power electronics and software to perform the same function.
The company imports power semiconductors, including insulated-gate bipolar transistors (IGBTs), which handle heavy currents, and silicon carbide components.
“India doesn't have semiconductor manufacturing capability, so the power semiconductors are something we import. The firmware, the magnetics, the design, the PCBs, everything is built in India,” Adya says.
The instruments business includes ultrasonic water meters, which use ultrasound to measure water flow and are still being rolled out, along with energy and gas meters.
Customers and revenue
About 90% of Enerzolve's revenue comes from component sourcing and engineering services, while its own products account for the remaining 10%, according to the company.
These products include uninterruptible power supply units, static frequency converters, energy meters, and water meters, Adya says.
Enerzolve sells to businesses and institutions, and currently has 35 paying customers. The Defence Research and Development Organisation (DRDO) buys a power supply unit from the company, while Enerzolve has qualified in tenders from Hindustan Aeronautics Limited (HAL), which requires static frequency converters.
The startup has raised about $5.1 million in a seed funding round led by Jungle Ventures and Kae Capital.
Reducing dependence on imports
According to Adya, developers of utility-scale battery storage systems are the target customers for Enerzolve's power conversion systems. For its solid-state transformer, the company is targeting utilities that currently use conventional transformers, as well as data centre operators in the US.
Adya says the immediate priority is to replace imported equipment with products designed and manufactured in India, since much of the technology is currently sourced from overseas.
“Our second aim is the solid-state transformer, replacing the conventional, bulky, large transformers with software-driven power electronics devices,” Adya says.
