Abstract
A method of detecting faults in a solar power system includes monitoring at least one operating parameter including outputs from a solar module, inputs and outputs to a microinverter, and inputs and outputs of a power optimizer, comparing the operating parameter to at least one of an expected value or another operating parameter, using results of the comparing to determine if there is a fault event, analyzing a location of an entity in the system that generated the operating parameter to localize the fault event, and performing remedial action on a location of the fault event.
