WMGBIRM1MPI Includes Only:
- Solar radiation and temperature meter
- Solar radiation meter mounting kit for PV panels + probe for measuring the temperature of PV panels and the ambient temperature
- 5 V power supply with USB 2.0 output
- USB adapter for LoRa data transmission
- Carrying case
Features
- Measurement of solar radiation and temperature.
- The LoRa interface for communication with a master meter - offers a larger range than the Bluetooth technology!
- Automatic data synchronization with a master meter with reSYNC function.
- Built-in compass and inclination sensor.
- Built-in recorder that can be used to record solar radiation before constructing PV systems, as well as to measure the shading of existing systems.
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.
Simple and compact
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.
