Abstract: A photovoltaic power circuit is provided and includes a plurality of strings of connected photovoltaic panels operable to generate DC current from solar radiation. Each of the strings is connected to a solar inverter by a pair of fuses. A detection circuit is provided that is operable to detect when one of the fuses opens as a result of a fault, regardless whether the fault is temporary or continuing.
