PV combiner box
The PV combiner box is a pivotal component in solar photovoltaic power systems, designed to aggregate the direct current (DC) energy harvested from multiple photovoltaic modules. Its primary function is to consolidate this DC energy before it is conveyed to the inverter for conversion into alternating current (AC), which can then be integrated into the electrical grid or used for on-site consumption.
