12�2 Sensor Box Professional Plus
The Sensor Box Professional Plus is used to record the Irradiation from the sun. This accessory allows the
Solar-Log™ to calculate the deviations in the current output compared to the potential output.
Up to 9 Sensor Box Professional Pluses can be connected to the Solar-Log™. The solar radiation sensor
must be fitted in such a way that the sensor's solar cell and the plant's modules are aligned as similarly as
possible to the sun, i.e. the sensor must have the same alignment and inclination.
The sensors should be positioned in a way to best ensure that:
•
as little overshadowing as possible occurs
•
snow cover does not interfere disproportionately with the sensor functions
To achieve this, it is best to fit the sensor on the side or above the solar module. Fitting bars can normally
be used as a fitting surface with modules that are parallel to the roof protrusion. In other cases, a suitable
fitting support may have to be added.
If there are various module alignments at a plant, every alignment should be fitted with a Sensor Box Pro-
fessional Plus.
The Solar-Log™ can record and save additional environmental data with the Sensor Box Professional Plus
(with optional accessories). This environmental data includes:
•
Solar irradiation (integrated)
•
Module temperature
Module temperature is recorded by an integrated cell sensor, thus avoiding the costly process of
mounting a sensor on the back of the module.
•
Ambient temperature (optional, Article Number: 220062)
•
Wind speed (optional, Article Number: 220061)
The above data form important parameters in further evaluations and analyses to measure yield.
Notes on roof mounting
The irradiation sensor is specially designed for continuous use in outside areas (IP65). The cables supplied
with the Sensor Box Professional Plus are UV and weather resistant.

Please note when fitting the sensor that the connection cable must be arranged as shown in the drawing.
