Features: Easy Installation: solar photovoltaic combiner box, installed between solar panel and solar inverters, can achieve faster and safe installation. Various protections: protections includes overvoltage, overload, and protections functions, enabling remote communication and extending the working life of solar systems. Equipped with the most stable components, it maximizes the protections of our photovoltaic isolation switches, and the clear cover also facilitates checking the condition of the circuits breaker . The isolation switches allows indoor and outdoor installation, with built in switchgear that can effectively protecting against harsh weather and environmental conditions. Suitable for photovoltaic solar panel grids connecting systems and solar off grids systems, solar power generation systems. Household.
