Product Description

The combiner box is a wiring device in the photovoltaic power generation system that ensures the orderly connection and confluence function of photovoltaic modules. This device can ensure that the photovoltaic system is easy to cut off the circuit during maintenance and inspection, and reduce the range of power outage in case of photovoltaic system failure.
The combiner box means that the user can connect a certain number of photovoltaic cells with the same specification in series to form a photovoltaic tandem, and then connect several photovoltaic tandem to the photovoltaic combiner box in parallel. After converging in the photovoltaic combiner box, through the controller, DC distribution cabinet, Solar inverter, and AC distribution cabinet, a complete photovoltaic power generation system can be formed to achieve grid connection with the mains.
