Different Series of DC ISOLATORS for Solar System DC isolators, also known as DC disconnect switches or DC switch-disconnectors, are electrical devices used in photovoltaic (PV) systems to isolate and disconnect the DC power generated by solar panels. They provide a means of safely disconnecting the DC power from the PV system for maintenance, troubleshooting, or emergency situations. DC isolators are typically installed between the PV array and the inverter or charge controller. They serve as a
