Just imagine 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.


Because of its attractive purchase price and short payback periods, the sonnenBatterie is possibly your most economic access to clean energy.
