How the sonnenBatterie grants you up to 75% energy independence

The sonnenBatterie will store the surplus energy generated by your PV system in times when you don’t have any need for it. The stored energy from the daytime is then at your disposal in the evening and during the night.

But the sonnenBatterie is much more than just a battery, it’s an intelligent storage system that automatically adjusts the energy use so that most of your self-generated solar energy stays in your household.


At sunrise the solar panels start to produce energy, though not enough to cover the morning energy needs. The sonnenBatterie will bridge the gap with the stored energy from the previous day.


In the daytime the solar panels’ energy generation is at it’s peak. But since nobody is home the energy consumption is very low so that most of the generated energy is stored in the sonnenBatterie.


The highest daily energy consumption is in the evening when the solar panels produce little or no energy. The sonnenBatterie will cover the energy needs with the energy produced in the daytime.


Monitor your energy supply with the sonnenApp

With the sonnenApp you’ll be able to check your energy usage and production – anytime and from anywhere.

Use the sonnenApp on your smartphone or tablet to connect to your sonnenBatterie via the internet and to monitor, analyse and control the supply and demand of your household.
