The Huawei backup box-B1 is an EPS switch which allows Huawei systems to provide backup power. If the grid fails it switches to backup mode. Once the grid recovers it will automatically switch back to grid-connected mode.

The backup box has the advantage of offering a high power output of 3300VA. 

The backup box B1 is for use with three phase systems. It is compatible with SUN2000-3/4/5/6/8/10KTL-M1 Inverters.
