About

Lunar Energy designs and manufactures residential battery storage hardware and grid software, selling through solar installers to homeowners while contracting with utilities. Its Lunar System pairs modular batteries with a hybrid inverter, and its Gridshare software aggregates distributed home devices into virtual power plants, managing roughly 650 MW across some of the largest US VPP programs. Founded in 2020 by former Tesla Energy executive Kunal Girotra and headquartered in Mountain View, California, the company produces battery systems for about 10,000 homes per year and plans to quadruple manufacturing. In February 2026 it raised $232 million — a $102 million Series D led by B Capital and Prelude Ventures plus a previously undisclosed $130 million Series C led by Activate Capital — after a $300 million 2022 round from investors including Sunrun and SK Group.
