Fluke FLK-393-IRR-PVLEAD (5337401) Fluke IRR1-SOL Solar Irradiance Meter and Test Leads

Fluke FLK-393-IRR-PVLEAD (5337401) Fluke IRR1-SOL Solar Irradiance Meter and Test Leads

Make the critical measurements needed for installing, testing, maintaining, and reporting on solar panels or photovoltaic systems with one, easy-to-use 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 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. Additionally, the integrated compass and inclination sensor 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 IRR1-SOL is the single-handed solution that every solar installer and technician needs in their tool bag.

Applications:

• Photovoltaic system design and surveying: 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 to determine the actual solar irradiance (Watts/m²) and shading at the site to develop a baseline.

• Measuring: Once 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 IRR1-SOL to obtain the amount of solar irradiance necessary to calculate the IV curve of the power output.

• Comparing and diagnosing: Even 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.

Features:

• High precision mono-crystalline solar sensor: Instantaneous irradiance measurements up to 1400 W/m²
• Two options for temperature measurement: Use the built-in temperature sensor or the external suction mount temperature probe to measure ambient and panel temperature
• Integrated compass: Measure and document roof or site orientation
• Inclination sensor: Know roof and PV panel tilt when surveying, installing, or adjusting the installation

    CISPR 11: Group 1, Class A
    Group 1: Equipment has intentionally generated and/or uses conductively-coupled radio frequency energy that is necessary for radio frequency energy that is necessary for the internal function of the equipment itself. Class A: Equipment is suitable for use in all establishments other than domestic and those directly connected to a low voltage power supply network that sup-plies buildings used for domestic purposes. There may be potential difficul-ties in ensuring electromagnetic compatibility in other environments due to conducted and radiated disturbances.
    Caution: This equipment is not intended for use in residential environ-ments and may not provide adequate protection to radio reception in such environments.
