Application

Suitable for PV power systems, Solar PV cable is designed for DC connections between PV modules, series cables between module strings, and parallel cables from strings to the DC distribution box, as well as from the DC distribution box to the inverter. They also serve as ACconnectionsbetween inverters and thepower grid.
