To optimize the self-consumption of a PV system, an XPB Wall with 11 kW output and 20 kWh storage capacity was installed in Linz - Austria. The customer can also look forward to a backup function.
If a blackout occurs in the region, the Power Box will disconnect within seconds from the power grid and forms an own grid for residential consumers. This means that his PV system resumes work and the residents continue to have a secure energy supply. Once the grid operator has solved the problem, an uninterrupted back synchronization and reconnection to the power grid follows automatically.
