AC Combiner Cabinet (400V)

QCB-400V

The QCB-400V AC combiner cabinet is used for parallel use of multiple energy storage cabinets, and supports access to a maximum of 5 energy storage modules to form a parallel system. It can rapidly expand the capacity and power of the energy storage system while isolating the energy storage from the power grid, which is convenient for construction, installation and daily maintenance.
