The box is used in PV systems on residential building roofs to switch the inverters to grid-connected or grid-decoupled status. If the utility grid fails, the backup box switches the inverter to grid-decoupled status and supplies power in emergency mode. As soon as the power grid is working again, the backup box automatically switches the status back over. Advantages: Automatic switching / reliable emergency power supply even in the event of a power failure / installation and commissioning are uncomplicated
