Just imagine if you had the chance to take your energy future into your own hands.

The sonnenBatterie eco – the start of your independence

The sonnenBatterie is not just a battery, it's an intelligent storage system that automatically adjusts the energy usage in your household. In combination with solar panels the sonnenBatterie will enable you to supply yourself with clean energy – thus making you independent and protecting you from energy price hikes.

The sonnenBatterie has a minimum lifespan of 10,000 charging-cycles. So you can rest assured that it will supply you with clean energy for many years to come.



In the sonnenBatterie we exclusively use lithium iron phosphate batteries – the safest lithium battery technology available today.


Become independent.

With a sonnenBatterie you can cover a huge part of your energy needs with self-produced, clean energy. Those people already decided to become independent from conventional energy and increasing prices.

Thanks to my sonnenBatterie I don't have to put up with conventional power companies and their ever rising energy prices.
