NOTE
Please note that the maximum pulse rate may not be greater than 15 pulses/
sec. Calculate the pulse rate depending on the size of the solar system using
the following formula:
Pulse rate [pulses/kWh] = 50,000 / system size [kWp]
The pulse rate must be set on your Solar Inverter and on the large display.
Temperature and irradiance
sensor
The optional addition of an irradiance sensor (model Si-01TC-K from Ingenieur-
büro Mencke & Tegtmeyer) with an integrated PT-100 temperature sensor for
temperature measurement enables the acquisition of irradiation data and the
corresponding module temperature and storage in the internal data memory as
a 5-minute mean value. This additional measuring unit helps analyse the system
output. Based on the values, any errors on the PV generator, e.g. shading or fai-
lure of solar cells, can be detected.
The sensor is activated via the display. In the menu Settings - Network - Inter-
faces you can select the sensor type in the Irrad. and Temp. field.
