PV combiner box

During the power generation of the PV array, the DC current generated by multiple branches of PV modules first flows into the combiner box. Through internal protection devices such as surge arresters, fuses, circuit breakers and anti-reverse diodes, it realizes the orderly convergence of multi-channel current, reduces the number of cables, simplifies the system wiring structure, and improves the standardization of power station wiring and convenience for later operation and maintenance. Meanwhile, it can effectively suppress overvoltage impacts such as lightning and surges, avoid current backflow between strings, and quickly cut off the circuit in case of branch overload, short circuit and other faults, so as to protect core equipment such as PV modules and inverters from damage and ensure the stable and safe operation of the entire photovoltaic system.
