HUAWEI Backup Box B1 – backup power module

The emergency power supply module for 3-phase M1 series inverters has a separate single-phase circuit. In the event of a power failure in the grid, the inverter switches to island operation and supplies power to loads not connected to the power grid in backup power mode. After the grid failure has been rectified, the inverter switches back to the grid-connected state. The SPD overvoltage protection must be installed in the Backup Box B1 circuit on the power grid side.
