Solar Irradiance Meter for IEC 62446-1 Compliance

The Fluke IRR1-SOL measures instantaneous solar irradiance up to 1400 W/m² using a high precision mono-crystalline sensor. It also captures ambient and PV module temperature up to 125 °C with a built-in sensor or external suction probe. Integrated compass and inclination functions document roof orientation and panel tilt angles. A carrying case with shoulder strap is included for rooftop access.

Verify Measurement Requirements

Confirm that instantaneous irradiance readings up to 1400 W/m² satisfy the IEC 62446-1 testing protocol for your installation. Ensure the external temperature probe suction mount is compatible with the specific panel surface materials on site. Check that the integrated compass and inclination sensor provide the orientation and tilt data format required for your documentation workflow. The unit ships with four AA batteries for immediate operation.

Sustained Operation in Direct Sunlight

The high contrast LCD maintains readability during prolonged exposure to bright sunlight while surveying arrays. Internal components are rated for ambient conditions up to 125 °C when measuring panel surface temperatures. The mono-crystalline sensor delivers stable irradiance data throughout extended survey sessions without drift. The carry case protects the instrument during repeated transport between rooftop locations.

Questions about this item

What comes in the box and do I need to buy anything extra to start measuring?

The meter ships with a carrying case, an external suction-mount temperature probe and four AA batteries, so you can take irradiance, temperature, orientation and tilt readings straight away.

Which version of the Fluke IRR1-SOL should I choose for IEC 62446-1 compliance?

This single model measures irradiance up to 1400 W/m² and temperatures up to 125 °C, meeting the IEC 62446-1 requirement for instantaneous watts-per-square-metre readings.

What does the 1400 W/m² irradiance limit mean when I am on a rooftop?

It lets you capture peak solar irradiation on clear days, giving the instantaneous W/m² value the standard demands for performance verification and site assessment.
