In the photovoltaic power generation system, the combiner box is a wiring device that guarantees 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.

The combiner box means that the user can connect a certain number of photovoltaic cells with the same specifications in series to form a photovoltaic string, and then connect several photovoltaic strings in parallel to the photovoltaic combiner box. After converging in the photovoltaic combiner box, through the control A complete photovoltaic power generation system is formed by supporting the use of the DC power distribution cabinet, photovoltaic inverter, and AC power distribution cabinet, which can be connected to the mains grid

Combiner boxes are divided into three types in terms of function. The first type is basic type without anti-reverse and monitoring functions; the second type is equipped with anti-reverse functions without monitoring function; and the third type is with anti-reverse function and monitoring. Function  

this is basic type without anti-reverse and monitoring functions  with Lightning protection, waterproof grade ip65
