Sonnen

Sonnen is a German energy technology company founded in 2010, now part of the Shell group, that develops decentralized battery storage for homes and small businesses across more than a dozen countries. It was created to let energy users store self-generated solar power and reduce reliance on the traditional grid.

Its main product, the sonnenBatterie, pairs with rooftop solar to store and release electricity through the sonnenCommunity virtual power plant network, while the sonnenCharger adds electric-vehicle charging. Systems reach customers through a network of solar installer partners across Europe, the United States and Australia.
