Switching Variant 1: Signal Contact for Overvoltage Protection
The DC OVP Typ 2 (overvoltage protection) option issues a warning or error on the display,
depending on the setting in the basic menu. More detailed information on the DC OVP Typ
2 option can be found in the installation instructions.
Switching Variant 2: S0 Counter
A counter for recording self-consumption per S0 can be connected directly to the inverter.
This S0 counter can be placed at the feed-in point or in the consumption branch. A dynamic
power reduction can be set under the menu subitem UC Editor in the settings on the Fro-
nius Datamanager website (see Fronius Datamanager operating instructions at
www.fronius.com/QR-link/4204260173DE).
IMPORTANT! Connecting an S0 counter to the inverter may require an inverter firmware
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:
"Solar Net" LED
Description "Solar Net" LED Lights Up:
Power supply for data communication within the Fronius Solar Net/Interface Protocol is
OK.
"Solar Net" LED Flashes Briefly Every 5 Seconds:
Data communication error in Fronius Solar Net:
-
Overcurrent (current flow > 3 A, e.g., due to a short circuit in Fronius Solar Net Ring)
- Undervoltage (not a short circuit, voltage in Fronius Solar Net < 6.5 V, e.g., when too
many DATCOM components are connected to Fronius Solar Net and electrical supply
is insufficient)
In this case an additional energy supply to one of the DATCOM components via an
external power supply is required.
