Fluke IRR1-SOL Solar Irradiance MeterMake the critical measurements needed for installing, testing, maintaining, and reporting on solar panels or photovoltaic systems with one, easy-to-use Fluke tool.The Fluke IRR1-SOL Irradiance Meter has been designed from the ground up to simplify the installation, commissioning, and troubleshooting of photovoltaic arrays, measuring irradiance, temperature, inclination and direction of the solar array in a single handheld tool. With a rugged, compact design, a protective carrying case, and an easy-to-read, high contrast LCD screen to read measurements in direct sunlight, the Fluke IRR1-SOL can go where you go. The simple user interface, instantaneous solar irradiation measurements and built-in temperature sensor make it easy to meet the IEC 62446-1 requirements for testing, documenting, and maintaining photovoltaic systems. The Fluke IRR1-SOL Solar Irradiance Meter features an integrated compass and inclination sensor which allow you to quickly measure and document roof and site orientation, pitch, and panel tilt while surveying, installing, or adjusting an installation.Whether working on a roof-mounted system or on a large field installation, the Fluke IRR1-SOL is the single-handed solution that every solar installer and technician needs in their tool bagFluke IRR1-SOL Key FeaturesMeasure solar irradiance, ambient and PV module temperature, array orientation and tilt anglesMake instantaneous measurements to determine the watts per square meter solar irradiation, required by IEC 62446-1 standardHigh contrast LCD with large numbers for easy readability in direct sunlightIncludes convenient Fluke C250 carry case with shoulder strapFluke IRR1-SOL ApplicationsPhotovoltaic system design and surveyingUse theFluke IRR1-SOL to find the expected production at a site, determine your solar resource while taking shading into account. The solar resource is measured in peak sun hours: the number of hours per day with 1,000 watts generated per square meter of solar array. Location, time of day, season, and weather conditions all influence peak sun hours. Use the Fluke IRR1-SOL Solar Irradiance Meter to determine the actual solar irradiance (Watts/m?) and shading at the site to develop a baseline.MeasuringOnce your system is installed, make sure it is operating as designed by measuring its electrical characteristics and the actual power output of the array. The performance of a photovoltaic array is based on its current-voltage (IV) curve. Use the Fluke IRR1-SOL to obtain the amount of solar irradiance necessary to calculate the IV curve of the power output.Comparing and diagnosingEven when installed correctly, a photovoltaic system may not be producing the expected electrical output. In order to produce the expected output the system needs to receive the correct amount of irradiance energy to generate the DC voltage that is fed into the inverter.Supplied withFluke IRR1-SOL Solar Irradiance MeterFluke 80PR-IRR External Temperature Probe with Suction CupFluke C250 Carrying Case with Shoulder StrapAA Alkaline Batteries (4)User Manual
