Lunar Energy, a developer of home energy storage systems, has raised $232 million in a combination of Series C and Series D funding, bringing its total funding to over $500 million. The Series D round was co-led by B Capital and Prelude Ventures, with the Series C being led by Activate Capital. Sunrun, a key strategic partner and investor, also participated in the rounds.
The new capital is earmarked for scaling the production and deployment of its home battery hardware across the U.S. and expanding its AI-powered Gridshare software platform. Founded by former Tesla Energy executive Kunal Girotra, Lunar aims to increase its manufacturing capacity from 10,000 battery systems per year to 20,000 by the end of 2026. The company's software manages distributed energy resources, creating "virtual power plants" that can support the grid, with programs already active in partnership with Sunrun.
