The Huawei Back-Up Box is used in a residential rooftop PV plant system to control the inverter grid-tied or off-grid state
It works with Huawei LUNA 2000 Batteries and SUN2000-3/4/5/6/8/10KTL-M1 inverters
- When the grid fails, the inverter switches to the off-grid state and supplies power to off-grid loads in backup mode. When the grid recovers, the inverter switches back to the grid-tied state.
Simple and Reliable
- Automatic detection of grid failure and instant switchover to off-grid mode, providing reliable and constant backup power to the loads
