sonnenBatterie - the start of your energy 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 no quibble, full 10-year warranty. So rest assured that it will supply you with clean energy for many years to come.



Safety is a top priority for us, therefore we exclusively use lithium iron phosphate batteries – the safest lithium battery technology available today.
