pv combiner box is a wiring device in pv power generation system to ensure the orderly connection of pv modules and the confluence function. It means that users can connect a certain number of pv cells with the same specifications in series to form a pv string, and then connect several The pv series is connected in parallel to the pv combiner box. After the pv combiner is combined, the controller, DC distribution cabinet, pv inverter, and AC distribution cabinet are used together to form a complete pv power generation system. Power grid connection.

In order to improve the reliability and practicability of the system, a pv special lightning protection module, a DC fuse and a circuit breaker are arranged in the pv lightning protection combiner box, so that users can accurately and timely grasp the working conditions of pv cells and ensure solar pv power generation. The system works best.
