Irradiation Sensor

This sensor is for measuring the irradiated energy and is in most cases fixed on the frame of the solar module.

Comparison of the irradiated power to thus 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.

Ambient temperature sensor

Due to its large temperature range the ambient temperature sensor is suited for measuring outside temperature as well as room temperature.

Technical data
Sensor	PT1000
Measuring range	-40°C to +180°C
Accuracy	±0.8°C (in the range -40°C to 100°C)
Design	Sensor in a cylindrical housing of stainless steel
Dimensions	Length 50 mm, Ø 6 mm
Cable	3 m Cu-cable; 2 x 0.5 mm, silicon isolated, ferrules, UV-resistant
Max. cable length (distance: Sensor Card/Box - sensor)	20 m

Mounting tip: For this sensor, there is no special mounting construction. The ambient temperature sensor can e.g. simply be placed under the pv-modules.

Module temperature sensor

In general this sensor measures the temperature on surfaces. By fixing the sensor on the back side of the pv-module, the module temperature can be told.

The temperature of the pv-module is one of the decisive facts for the power output. By supervision, the pv-owner can draw conclusions to the performance of the power chart.

Technical data
Sensor	PT1000
Measuring range	-20°C to +150°C
Accuracy	±0.8°C (in the range -20°C to 100°C)
Design	Sensor on an adhesive film for measurement on sheets
Dimensions	50 x 100 mm
Cable	3 m Cu-cable; silicon isolated, ferrules, UV-resistant
Max. cable length (distance Sensor Card/Box - sensor)	20 m

Mounting tip: It is recommended to fix the sensor and the cable with an additional adhesive tape.

Wind speed sensor

The sensor measures exactly the speed of wind.

It is a useful in combination to the other sensors and to complete the private weather station.

Technical data
Sensor	Cup Anemometer
Output signal	Rectangle: Low ≤ 0.5V / High ≥ 4.5 V
Calibration factor	5.22 Hz = 1 km/h 18.79 Hz = 1 m/s
Threshold	2.5 m/s wind speed
Resolution	1 m/s; 1 km/h
Accuracy	±5 % at wind speed ≥ 5 m/s
Degree of protection	IP 54
Ambient temperature	-20°C to +60°C
Dimensions	85 x 93 x 115 mm
Cable	2 m CU-cable, ferrules, UV-resistant
Max. cable length (distance: Sensor Card/Box - sensor)	30 m
