In solar photovoltaic power generation systems, the PV combiner box is essential for reducing incoming lines between the cell array and the inverter. It improves system reliability and facilitates easy installation and maintenance. Users can connect multiple series of photovoltaic cells into the combiner box, which then outputs to the inverter through lightning protection and circuit breakers.
