Huawei Backup Box-B1 facilitates the independent operation of Huawei three-phase inverters SUN2000 (M1) with accumulators LUNA2000.
In case of power outages, the Backup Box directs the energy from the photovoltaic panels and batteries to a defined group of emergency consumers (backup solution).
All critical consumers must be connected only on one of the current phases.The maximum delivered power is 3.3 kW, respectively 3.0 kW (Huawei SUN2000-3KTL-M1).
After the restoration of the power network, the supply will be fully redirected to the other consumers.
