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.

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
