IRM-1, small, but indispensable for testing PV systems. By measuring solar radiation values, as well as panel and ambient temperatures, it provides the necessary data to convert the results into STC conditions. A built-in recorder with a memory of 5000 records enables the instrument to be used as a tool in the PV plant design process, as well as to diagnose panel shading problems.
Measured parameters
- Solar radiation intensity (irradiance) in W/m2 or BTU/ft2h.
- PV panel temperature in °C or °F.
- Ambient temperature in °C or °F.
- Inclination angle of panels
- Orientation of the panels with the built-in compass.
Tightness and durability
The meter performs well in harsh environmental conditions. Protection against the ingress of dust and water is provided by the housing rated at IP65. This is especially important for measurements on photovoltaic systems, which are outdoor installations.
Communication and software
Measurement data from the IRM-1 can be transferred to a computer via the USB port. In addition, the device has a built-in wireless LoRa interface (Long Range) for automatic data exchange with the master meter – even over long distances.
