The PV combiner box is a complete set of devices to ensure the orderly connection and convergence of PV strings in the PV power generation system. Generally equipped with surge protectors, leakage protectors, isolation switches, fuses, etc., it provides isolation, leakage and grounding protection, ensures that the PV system is easy to cut off the circuit during maintenance and inspection, and reduces the scope of the blackout when the PV system fails to improve the performance of the PV system. So how does a PV convergence box work? Power Home will answer your questions in this blog!
