Abstract: Provided is a fault isolation apparatus for an inverter configured for coupling to an external power supply. The apparatus includes a plurality of fault detection devices, each configured to (i) complete an electrical path between the inverter and the external power supply and (ii) detect a fault along its respective electrical path. The apparatus also includes a controller configured to instruct the fault detection device to complete its respective electrical path only when the path is devoid of the detected fault.
