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.
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.
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. 5 MW unit is designed to weigh about two tonnes.
