S0 interface
Temperature and irradiance
sensor
IPE 030 - 033 CN 05
To do this, if a system has a Schüco inverter then the CAN bridge can be directly
integrated into the inverter, over which a 24 V DC power supply unit can be supplied
with electricity.
The S0 pulse output enables, for example, the connection of a large display (Schüco
display) for displaying the momentary output, the energy yields and the CO
tion.
You can use the S0 interface on the master if you want to transmit the entire line
yields as a sum to a large display.
The S0 interface is adjusted via the display on the inverter. Go to Settings - Networ-
king - Interfaces.
NOTE
x 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 fol-
lowing formula:
Pulse rate [pulses/kWh] = 50,000 / system size [kWp]
x The pulse rate must be set on your inverter and on the large display.
The optional addition of an irradiance sensor (model Si-01TC-K from Ingenieurbüro
Mencke & Tegtmeyer) with an integrated PT-100 temperature sensor for tempera-
ture 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 failure of solar cells, can be
detected.
The sensor is activated via the display. In the menu Settings - Network - Interfaces
you can select the sensor type in the Irrad. and Temp. field.
