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