Huawei's Backup Box provides automatic detection and switching, providing reliable backup power.
The Backup Box is used in a residential rooftop PV system to monitor the inverter grid connected
or off grid.
When the grid fails, the inverter switches to the off-grid state and supplies power to off-grid loads in backup mode.
When the grid recovers, the inverter switches back to grid-tied state.
The Box is compatible with the following Huawei inverters: SUN2000-3/4/5/6/8/10KTL-M1.
