The IEC 62446-1 is an international standard for testing, documenting, and maintaining grid-connected photovoltaic systems. Learn more about the DC-side testing of this standard. . This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www. This report was prepared as an account of work sponsored by. . A ground fault in a photovoltaic (PV) array is an accidental electrical short circuit between ground and one or more conductors that normally carry current. PV ground faults have many potential causes, but most result from improper installation or damaged components. For example, a frayed wire. . A PV technician using a DMM to measure voltage in a combiner box - the first step in finding a ground fault. . This process involves two distinct but related concepts: system grounding, which provides a reference to earth for the electrical system (stabilizing voltages and assisting in clearing certain faults), and equipment grounding, which bonds all normally non-current-carrying metallic parts to provide. . This article discusses the DC side testing of the IEC 62446-1 standard.
