The start of your 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 sonnenVatterie has a minimum lifespan of 10,000 charging-cycles. You can rest assured that it will supply you with clean energy for many years to come.


In the sonnenBattery, we exclusively use lithium-iron phosphate batteries - The safest battery technology available today.


With an attractive purchase price and short payback periods, the sonnenBatterie is possibly your most economic access to clean energy.

Intelligent, long lasting and

economical - the sonneBatterie

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.

How the sonnenBatterie

Gets you through the day


Clean energy during the daytime, in the evening and at night


minimal energy production with 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.


highest energy production

with 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.


low energy production and 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.
