Abstract
An apparatus, method, and system for detecting arc-faults in a photovoltaic array are disclosed. Further, the detection not only identifies that an arc-fault is present in the array, but also classifies whether the arc-fault is a series type arc-fault or a parallel type arc-fault. Upon determination of the specific type of arc-fault that is at issue, de-energizing the arc-fault specific to the type is selected and carried out.
