A counter for recording self-consumption per S0 can be connected directly to the inverter
(Fronius Galvo and Fronius Symo only).
IMPORTANT! An S0 counter is connected to the switchable multifunctional current inter-
face of the inverter. Connecting an S0 counter to the inverter may require an inverter firm-
ware update.
Requirements for the S0 counter:
- Must meet standard IEC 62053-31 Class B
- Max. voltage: 15 V DC
- Max. current when ON: 15 mA
- Min. current when ON: 2 mA
- Max. current when OFF: 0.15 mA
Recommended max. impulse rate of S0 counter:
