Product Description
The combiner box is a essential wiring device in photovoltaic power generation systems that ensures the orderly connection and confluence of PV modules. This device ensures that the photovoltaic system is easy to isolate during maintenance and inspection, significantly reducing the range of power outages in case of system failure.
Users can connect a specific number of PV cells with the same specification in series to form a tandem, then connect several tandems to the combiner box in parallel. After converging, the power flows through the controller and inverter to achieve a complete grid-connected system.
