Reaching maximum independence

Thanks to innovative storage solutions, independence from the grid is now higher than ever before: The combination of solar system and battery storage covers up to 80% of the needs of a household, depending on the season.

The possibilities of self-supply with solar energy have been limited for a long time: During the day, more electricity was produced as needed and at night no own solar power was available. Due to the lack of appropriate storage solutions, the share of solar energy in the total electricity demand was only up to 30%.

With the introduction of innovative storage solutions, this value can now be raised by up to 80%, depending on the weather conditions: The energy produced during the day is saved and can be used at any time of day, even at night.

Use of solar power during the day

Operation of solar system and storage in the daily routine:


The energy produced in the solar system is used for own consumption. Surplus energy is stored in the battery.


With a fully charged battery, the system continues to supply the own consumption. Surplus energy is fed into the public power grid.


After sunset, the system provides the stored energy from the battery for own consumption.


Even at night, the system continues to provide stored energy. If there is insufficient battery capacity, additional power is obtained from the public power grid.
