Combiner box:

In the photovoltaic power generation system, the combiner box is a wiring device that ensures the orderly connection of photovoltaic modules and the function of combining. 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 one photovoltaic series, and then connect several photovoltaic series in parallel to the photovoltaic combiner box. inverter, DC power distribution cabinet, photovoltaic inverter, and AC power distribution cabinet are used together to form a complete photovoltaic power generation system, which can be connected to the grid.

The combiner box is divided into three types in terms of functions. The first type is the basic type, without anti-reverse function and monitoring function; the second type has anti-reverse function and no monitoring function; the third type has both anti-reverse function and monitoring function. It has the most complete functions and the highest cost and price in the combiner box.

Since the photovoltaic combiner box is installed in an outdoor environment, we must consider lightning strike protection for the combiner box. To this end, we have connected a lightning strike surge protector (ie, lightning arrester) dedicated to photovoltaic DC in parallel with the DC output part of the combiner box.
