What is the difference between a string inverter and a DC combiner?The string inverters are installed at a central location in the ground-mounted PV system, while the DC combiner boxes are distributed in the field near the panels. As a result, the lengths of the cables between the inverter and transformer are short, and there is minimal power loss on the AC side. The power loss can be reduced by up to 1.5% per km.
