FLUKE 393 FC True-RMS and IRR1-SOL Solar Clamp Meters Kit with iFlex is an industrial clamp meter designed for solar photovoltaic (PV) installation technicians and maintenance professionals who work in high voltage DC environments. Safely connect the MC4 test leads to the clamp meter to validate voltage and current from individual panels or a series of panels in a PV array. The PVLEAD1 solar MC4 test leads connect measuring devices to PV power plants for regular examinations, measurements, and troubleshooting on solar PV panels. The inline capabilities of the PVLEAD3 solar MC4 test leads allow the system to remain online and generating power while testing without needing to pierce the line. Use the IRR1-SOL to obtain the amount of solar irradiance necessary to calculate the IV curve of the power output. Validate that the panel or string of panels are outputting the correct voltage.
