Series Pro
From the electric car to your wall: The most sustainable storage in the world.
Why waste resources when they can live on? We transform high-quality electric car batteries into powerful wall storage, thereby giving them an additional lifespan of 10 years.
Massive CO₂ savings compared to new production, and you can rely on a true circular economy.
Perfectly connected
The storage integrates seamlessly into the modual ecosystem. Use the Solar Manager integration for maximum efficiency, peak shaving in commercial settings, or to optimize your self-consumption.

Save costs through simplicity
The fairest energy storage on the market.
Fairness means transparency and security for us. With this modual system, you get the cheapest kilowatt-hour in our entire range. We are confident in our quality and offer you up to 20 years warranty (with warranty extension). If the performance after 10 years no longer corresponds to the sold value, we will replace the storage without complications. At the same time, we prevent battery waste mountains together by sensibly continuing to use high-quality e-car technology.
Unbeatable price per kWh
We have calculated sharply: This system is, in terms of available capacity (kWh), the most cost-effective solution in our portfolio. You do not pay for unnecessary frills, but for pure, reliable performance at your wall.
20 years worry-free guarantee
With extended warranty: 20 years warranty including replacement service if performance does not meet the purchase promise after 10 years.
No battery graveyards
No more images of huge piles of discarded electric car batteries. We are actively countering this excess by giving functioning batteries a meaningful purpose instead of disposing of them. A clear statement against waste.
