Together with the Sonnenprotect 8000 emergency power box, the home storage system is also capable of operating in off-grid mode. If the public power supply fails for a longer period of time, it can set up a self-reliant power grid in the house so that the photovoltaic system and storage unit continue to provide energy as usual. The system offers this possibility in both AC and DC versions.

Another new feature is the sonnen DC module: This allows the AC version to be converted into a hybrid version by the installer in just a few steps. The system can then be black-started and can automatically restart power generation during a power failure. With these features, the new Sonnenbatterie is also suitable for small businesses or farmers who require three-phase current and higher storage capacities. (mfo)
