Product Description

DC Combiner Box:


The role of the PV combiner box is to bring the output of several solar strings together. In the solar power system, in order to decrease the connecting line, easy maintenance, reduce losses, optimize system structure, improving the safety and reliability of items, the PV combiner box is usually in need between the solar panels and inverter. The quality of the combiner box is the most important consideration when selecting one, especially since it’s the first piece of equipment connected to the output of the solar modules.
