VARTA energy storage system

The basic idea of an energy storage system is the ideal management of the differences between the generation of electricity and the actual consumption. With a VARTA energy storage system, you can temporarily store the energy you’ve produced yourself and then use it when you actually need it. This enables you to use green energy 24 hours a day and increase your self-consumption to 80% and more.
