Pv Combiner Box

Product Overview

The combiner box integrates fuses, surge arresters, circuit breakers, and a parameter acquisition module, with an optional single-string array anti-reverse function. The applicable voltage range is 100VDC to 1000VDC, and the applicable current range is 10A to 160A, covering the configuration needs of mainstream PV modules. The enclosure uses high-quality all-metal galvanized hinges, with the door able to open 180 degrees to either the left or right, and a fully sealed cable entry design that effectively prevents foreign object intrusion. The surface is treated with electrostatic spray coating for durability. A high-quality grounding wire is provided to reduce the risk of accidents and ensure safe operation.
