12 In 1 Out PV DC Combiner Box

      This 12-in-1-out PV combiner box integrates 12 independent PV strings into one single output circuit, suitable for medium and large centralized solar PV systems. Each string is equipped with a dedicated DC fuse for individual branch overcurrent and short-circuit protection. The main output circuit adopts DC MCB for overall system protection. Built-in Type II SPD effectively absorbs lightning surge and transient voltage risks. Adopting high-strength PC+ABS flame-retardant material, the enclosure supports IP65 waterproof, dustproof and UV-resistant performance for long-term outdoor use. Centralized wiring design simplifies on-site installation and later maintenance, widely applied in industrial and commercial solar projects and large-scale photovoltaic power stations.
