Sonnen Battery System


Intelligent, long-lasting and economical – the sonnenBatterie.

The sonnenBatterie is a high-tech storage system that has proven itself in thousands of households – every day. The combination of a PV system and a sonnenBatterie will allow you to cover about 75% of your yearly energy requirement with self-produced and clean energy.

Since your energy is being generated on your roof and not by some anonymous energy provider you are more independent than before. So take your energy future into your own hands and reduce your energy costs to a minimum. The decision for a sonnenBatterie is also a decision for the highest standards in safety and quality that “Made in Germany” stands for a system of this size.

How the sonnenBatterie gets you through the day

Clean energy for all: presenting the sonnenBatterie and the sonnenCommunity.

Morning: minimal energy production, high energy needs.

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.

Midday: highest energy production, low energy needs.

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

Evening: low energy production, high energy needs.

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

Technology from the market leader

The sonnenBatterie comes with the experience of 20,000 installed systems – build into each unit, the newest technology for highest independence and maximum longevity. All in a compact case that offers highest flexibility thanks to its modular design.

Keep an eye on 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 monitor, analyse and control the supply and demand of your household.

Meets your energy needs whether you are a small or a big family

Every household has its own very specific energy needs. That’s why the sonnenBatterie was developed as a multi-stage storage system that can be adapted to the most diverse energy needs. With storage sizes ranging from 2 kWh to 16 kWh the sonnenBatterie will power a detached house or a multi-family house. The sonnenBatterie’s energy capacity can be individually expanded in blocks of 2 kWh – should you ever feel the need to increase the power storage in your house.
