Huawei varusüsteem, varu Box-B0

The Backup Box-B0 separates the loads to prioritize the continuity of the most important loads when there is a power outage.
The BACKUP BOX-B0 module is used in residential photovoltaic systems for the automatic control of the transition of the single-phase HUAWEI inverter from On Grid to Off Grid mode when interruptions in the operation of the electrical network are detected. The Backup Box thus allows the supply of a group of essential consumers, through photovoltaic panels or HUAWEI LUNA 2000 batteries. After the restoration of the operation of the electrical network, all consumers will be fully supplied.
