Why energy storage?

How energy storage works

Morning: Minimal production, high demand

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

Midday: Highest production, lowest demand

In the daytime the solar panels energy generation is at its peak. But since no one is home your energy consumption is very low, so now, the generated energy is stored in your sonnenBatterie.

Evening: Low production, highest demand

The highest daily energy consumption is in the evening when the solar panels produce little or no energy at all. The sonnenBatterie will cover the energy need with the energy produced during the day.
