The Huawei Smart Backup Box-B0 allows the use of emergency power in case of a network failure.

Founded in 1987, Huawei is an innovative company that stands out for its inverters and batteries for energy storage. This Huawei Backup Box serves to monitor the state of the electrical grid. When the grid fails, the inverter switches to off-grid mode and provides backup power. When the grid returns, the inverter switches back to the grid inverter mode.
