The PV Combiner Box includes both AC and DC Combiner Boxes, which are wiring devices that ensure the orderly connection and merging of photovoltaic (PV) modules in a solar power generation system. This device enables easy disconnection of circuits during maintenance and inspections, and minimizes the scope of power outages in case of system faults. A combiner box allows users to connect a certain number of identical PV modules in series to form a PV string, which can then be connected in parallel to the combiner box. After merging within the combiner box, the electricity is managed through a controller, a DC distribution cabinet, a PV inverter, and an AC distribution cabinet, thus forming a complete solar power generation system that can be grid-connected. This technology is widely used in homes, solar power plants, and solar water pumping and energy storage systems.
