Faults occur at the beginning and end of the Solar Net ring or between the con-
nected inverters – the primary inverter stops sending the signal, and secondary
inverters switch off with status 710.
Description of
The "Fronius Solar Net" LED is on:
the "Fronius Sol-
the power supply for data communication within the Fronius Solar Net / inter-
ar Net" LED
face protocol is OK
The "Fronius Solar Net" LED flashes briefly every 5 seconds:
data communication error in the Fronius Solar Net
-
-
After cutting out because of overcurrent or undervoltage, the inverter attempts
to restore the power supply in the Fronius Solar Net every 5 seconds while the
fault is still present.
Once the fault is rectified, power to the Fronius Solar Net will be restored within
5 seconds.

Overcurrent (current flow > 3 A, e.g. resulting from a short circuit in the
Fronius Solar Net ring)
Undervoltage (not a short circuit, voltage in Fronius Solar Net < 6.5 V, e.g. if
there are too many DATCOM components on the Fronius Solar Net and not
enough electrical power is available)
In this case, power for the Fronius DATCOM components must be supplied
by connecting an additional power supply (43,0001,1194) to one of the
Fronius DATCOM components.
To detect the presence of an undervoltage, check some of the other Fronius
DATCOM components for faults as required.
