Connecting accessories
Connection through S0 output
If the S0 output is used, only the current feed-in power can be transmitted in the form of a pulse sequence.
The display has to calculate the power output and total yield by itself.
Wiring for a contact-controlled S0 output
Example: RiCo Electronic
The wiring consists of a 2-pin shielded cable (2x0.6 mm)
(max. length 100 m) and terminal block connector.

6 S0+
Further information about the connection can be obtained from the manufacturer of the display.
Pulse factor
In the standard setting, Solar-Log™ sends 1000 pulses/kWh over the S0 output. The pulse factor must be
configured according to the size of the plant (kWp) in the Configuration | Devices | Definition | External
Display menu.
Pulse factor / plant size
Plant size kWp Pulse factor
30 kWp 2000
60 kWp 1000
100 kWp 600
150 kWp 400
300 kWp 200
600 kWp 100
Note
The impulse factor in the Solar-Log™ and the connected device has to be identical.
