of the circuit under test. For larger systems, where the shorting device may have to be rated for high current and voltage levels, the open-circuited option may be preferred. The open-circuited option requires the user to correct readings to account for the PV-generated voltage, and the procedure for making such corrections is beyond the scope of this test method. The short-circuited option may be easier for small systems where the voltage and current levels are low and the distance between the
