Abstract
A PV installation comprises a PV array, an electrical interface connecting a utility power source to an electrical load, and a DC to AC inverter. A first set of wiring electrically connects the PV array to the inverter through a disconnect device and a second set of wiring electrically connects the inverter to the electrical interface. A control mechanism connects the disconnect device to the electrical interface so that when power from the electrical interface is removed, the PV array is electrically disconnected from the inverter. The disconnect device may be a remote disconnect device located at a position at or near the PV array, such as in the space beneath a roof supporting the PV array. A method electrically disconnects a PV array from electrical wiring at a site.
