Lunar Energy raises $232M to deploy home batteries that prop up the grid

Lunar Energy, a six-year-old startup specializing in home battery packs for homeowners in California, Georgia, and Washington, has raised a total of $232 million through two recent funding rounds: a previously undisclosed $130 million Series C led by Activate Capital and a $102 million Series D led by B Capital and Prelude Ventures. The company aims to scale its manufacturing capacity to 20,000 units by the end of 2024 and reach 100,000 units by 2028, contributing to the growing market for stationary energy storage in the U.S. Lunar’s batteries, available in 15 kWh and 30 kWh modules, support grid resiliency by delivering power when needed and are managed through virtual power plant (VPP) software that also controls EV chargers and appliances to balance supply and demand. The rise of stationary batteries like Lunar’s reflects a broader shift in the energy sector, driven by increasing grid strain from electrification and data center growth. These modular batteries offer a versatile
