This classification handles junction boxes for power aggregation and distribution in solar power generation systems, and dedicated cables used for connections between solar panels and power conditioners. In industrial solar power generation facilities installed on manufacturing plant rooftops and premises, it includes string boxes, array boxes, and collection boxes that aggregate DC power from multiple solar panels, as well as solar power DC/AC cables with weather resistance and UV resistance, cables with MC4 connectors, and grounding cables. This category is distinguished from general electrical wiring materials and control panels, specializing in connection and wiring components dedicated to solar power generation systems.
