Huawei LUNA2000 Backup Box Backup Box-B1

The Three-Phase Backup Box-B1 is used in a residential rooftop PV plant system to control the inverter grid-tied or off-grid state. 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 the grid-tied state.

The grid-tied system of a rooftop PV plant consists of PV strings, an energy storage system (ESS), an inverter, a Backup Box, a management system, an AC switch, and a power distribution unit.

Compatible with Huawei LUNA2000 batteries and Huawei SUN2000-3/4/5/6/8/10KTL-M1 inverters.
