The combiner box has good waterproof performance and obvious heat dissipation effect, is easy to mount and store and also has a fire extinguishing function.

Description

technical field [0001] The invention relates to the technical field of combiner boxes, in particular to a multifunctional power combiner box. Background technique [0002] In the photovoltaic power generation system, the combiner box is a wiring device to ensure the orderly connection and confluence function of photovoltaic modules. The device can ensure that the photovoltaic system is easy to cut off the circuit during maintenance and inspection, and reduce the scope of power outage when the photovoltaic system fails. Then connect several photovoltaic series in parallel to the photovoltaic combiner box. After converging in the photovoltaic combiner box, the controller, DC power distribution cabinet, photovoltaic inverter, and AC power distribution cabinet are used together to form a complete system. The photovoltaic power generation system realizes grid connection with the mains, but the existing combiner box has poor waterproof performance, limited heat dissipation effect...

The device can ensure that the photovoltaic system is easy to cut off the circuit during maintenance and inspection, and reduce the scope of power outage when the photovoltaic system fails. Then connect several photovoltaic series in parallel to the photovoltaic combiner box. After converging in the photovoltaic combiner box, the controller, DC power distribution cabinet, photovoltaic inverter, and AC power distribution cabinet are used together to form a complete system. Photovoltaic power generation system realizes grid connection with mains power, but the existing combiner box has poor waterproof performance, limited heat dissipation effect, and the exposed installation structure is not convenient for storage, and has no fire extinguishing function
