4 In 2 Out PV DC Combiner Box

    This 4-in-2-out PV combiner box integrates 4 independent PV string inputs into one unified output, specially designed for medium-sized solar photovoltaic systems. Each input string is equipped with a DC fuse for individual circuit protection, while the main output is fitted with a DC MCB to provide overall overload and short-circuit protection. Built-in Type II SPD delivers reliable lightning and surge protection for the entire DC system. Adopting high-strength flame-retardant PC+ABS material, the enclosure features IP65 waterproof and UV-resistant performance, perfectly adapting to outdoor harsh environments. It features centralized wiring, simple installation and convenient maintenance, widely applied in rooftop solar systems and small-to-medium PV power stations.
