The solar power system AC/DC power distribution cabinet includes a DC power distribution unit and an AC power distribution unit. The DC power distribution unit provides a DC input and output interface. The DC power supply input from the PV module is mainly connected to the inverter or directly to the inverter. DC load (such as battery, charging power supply, etc.); AC power distribution unit mainly provides the grid connection interface to the inverter through the cabinet, and the output AC circuit breaker is directly used for AC load, and also contains (mains or generator) network. Side circuit breaker, photovoltaic lightning protection module, inverter output metering meter (with RS485 interface), AC grid side configuration voltage ammeter and other measuring instruments, etc., to facilitate system management.
