Fronius Irradiance Sensor


Fronius sensor insolation/irradiance IG, 43,0001,1189

SKU: FRO-221-158 Categories: , Tags: ,

The Fronius Irradiance Sensor measures the solar radiation intensity for use with the Fronius Sensor Card / Box and the Datamanager. This sensor is in most cases fixed on the frame of the solar module, so it is in the same plane and exposed to the same radiation level as the panels.

Comparison of the irradiated power to that of the inverter gives a rapid overview on the proper operation of the pv-system.


Technical data
Sensor Mono crystalline Si-Sensor
Sensor voltage approx. 70 mV at 1.000 W/m² (exact calibration voltage is written on the sensor)
Accuracy ±5 % (average over a year)
Ambient temperature -40°C to +85°C
Design Sensor is mounted on Z-shaped aluminium profile;
Dimensions (l x w x h) 110 x 40 x 40 mm
Cable 3 m Cu-cable; ferrules, UV-resistant
Max. cable lenghth
(distance: Sensor Card/Box – sensor)
30 m

Mounting tip: The sensor comes fixed onto an aluminium profile with an 8 mm hole. Thus screwing onto the module frame is very easy. Please mind, that the sensor does not cast any shadow on the module.
