HUAWEI Back Up Box B1 - for the M1 inverter series

Huawei Backup Box B1

Backup power module for Huawei M1 series three-phase inverters.
The Backup Box B1 is used in rooftop PV systems to control the grid and island operation status of Huawei M1 series three-phase inverter.
In the event of a grid failure (power outage), the inverter switches to the island operation state and supplies power to loads not connected to the grid in backup power mode.
When the grid failure is cleared, the inverter switches back to the grid-connected state. The Backup Box B1 supports the following grid systems: TN-S / TN-C-S / TT.
When installing the Backup Box B1 outdoors, avoid exposing it to direct sunlight.
It is recommended to install it in a sheltered place or install a cover on it. An SPD surge protector must be installed in the circuit of the Backup Box B1 on the power grid side.
