How the sonnenBatterie works.

The sonnenBatterie stores excess daytime energy generated by your solar system to be available to you in the evening when household demand is typically at its peak.

Morning: minimal energy production, high energy need.

At sunrise your solar panels start to produce energy but not enough to cover your morning energy needs. The sonnenBatterie bridges the gap with stored energy from the day before.

Midday: highest energy production, low energy need.

In the daytime production of energy from your solar panels is at its peak but since typically no-one is at home in the middle of the day your energy consumption is low. Your sonnenBatterie stores the energy that has been generated so that it is not wasted.

Evening: low energy production, high energy need.

Your highest energy consumption is in the evening when your solar panels produce little or no energy. The sonnenBatterie covers your energy needs with the energy stored from the day.

Cut the cost of your energy bills and reclaim your independence from conventional energy retailers.
