Description
Huawei Backup Box B1 Three Phase
The Huawei Back Up Box B1 Three Pahse is used in a residential rooftop PV plant system to control the inverter grid-tied or off-grid state. Huawei Backup Box has all the necessary automation built in so that when the external grid power fails, your Huawei inverter, in combination with the Huawei Luna2000 battery, can continue to operate and support the loads in your home. The Backup Box completely isolates your home from the external power supply, ensuring that the energy you generate cannot flow back into the grid. Once the grid is restored, the system will return to normal operation mode.
