Take your energy supply into your own hands.

"Our goal is a world in which everyone is able to cover their energy needs with decentralised and clean energy source. Everyone can connect with each other to share energy where and when it's needed. This will emancipate our world from the dependence on fossil fuels and anonymous energy corporations."

Christoph Ostermann, sonnen founder

VISION

Clean and affordable energy for everyone is the biggest challenge of our time

If we succeed to free our energy production from carbon-based emissions within the next 10 years we will not only protect our environment but also our economical and political freedom. Digital technology empowers us to interconnect thousands of people, who are already producing clean energy, to share their excess energy – directly on a non-profit basis – with others in their community. Our intelligent sonnenBatterie can optimise the energy supply and demand to such a degree that an integration of 100% renewable energy within a community is possible – 24/7.

WHO WE ARE

We believe that it is already possible to economically produce clean energy at home today

What started as an idealistic idea has become one of the biggest producers of intelligent energy storage systems. The headquarters of sonnen is in Wildpoldsried - a Bavarian village that is already running on 100% renewable and clean energy. Wildpoldsried is the development and production location of the sonnenBatterie - Lithium-storage systems market-leader- is now in Australia.
