Good reasons for VARTA.wall

Ultra slim system with high energy density
The VARTA.wall is the first storage system in a new generation of modular DC high-voltage storage systems from VARTA. It is equipped with state-of-the-art 21700 round cells and thanks to the VARTA double module, the VARTA.wall has a product depth of just 10 cm, making it particularly space-saving.

Made in Germany
Developed and produced in Germany: as the only supplier of energy storage devices, VARTA has 135 years of battery expertise as a battery manufacturer.

Easy Installation
Thanks to the simple VARTA plug-in system, the VARTA.wall does not require external wiring of the modules. Installation via app and the integrated WIFI hotspot also ensure simple and quick installation.

Three performance capacity through modular design
The modular, plug-in system is available in 10, 15 and 20 kilowatt-hour system capacities and is retrofittable. Ideal for almost any energy consumption.

Compatible with leading inverter manufacturers
The VARTA.wall is compatible with leading European inverter manufacturers, as well as the associated product range, such as some charging stations.

Highest safety standards
The integrated VARTA battery management system ensures the highest possible safety. During development, VARTA focuses on the highest current safety standards, also through the use of mechanically stable round cells.
