Twelve kilowatts of three-phase power are available - in line with the increasing requirements for charging EVs or heat pumps. The new home storage system also integrates a backup power solution that enables an AC island function as standard. In the event of prolonged power outages, the backup reacts within seconds so that the household can set up its own three-phase power grid. This ensures a power supply of up to eight kilowatts.

The integration of this function significantly reduces installation costs and space requirements, emphasises the manufacturer, as there is no need for an external emergency power box. The new Sonnenbatterie can also be combined with the recently introduced Home Charger two. There is also the option of participating in Sonnen's virtual power plant (VPP) via the community. The prerequisite for this is the conclusion of the Sonnenflat direct smart electricity tariff. (mfo)
