The Fluke FLK-393-IRR-PVLEAD is a photovoltaic troubleshooting kit that combines the Fluke 393 FC true-RMS AC/DC clamp meter, the IRR1-SOL solar irradiance meter and a set of MC4 test leads. The clamp meter measures current and voltage on PV strings and inverters, the irradiance meter records plane-of-array solar intensity for performance comparison, and the MC4 leads land directly on standard PV connectors. Typical applications include installation commissioning and field maintenance of solar photovoltaic systems.
