Channel 1 current differs from
the others
Channel 2 current differs from
the others
Channel 3 current differs from
the others
Channel 4 current differs from
the others
Channel 5 current differs from
the others
Difference between the output
of the insolation sensor and the
output of the inverter is too
large
Deviation in the insolation sen-
sor is too large
Insolation sensor does not out-
put any values or outputs un-
authorised values
Missing archive values
No connection to Fronius So-
lar.web
Difference in the kWh value for
the inverters (depending on the
settings in Fronius Solar.web)
Remedy
1. See device -> Info menu:

Check archive values, shad-
ing, string fuse and check for
faulty modules
Check whether the insolation
sensor is dirty, shaded or faulty
Check insolation sensor wiring
Check archive values in Froni-
us Solar.web server or Data-
logger
1. Check LED status on the
Datalogger
2. Restart Datalogger
3. Check internet connection
4. Check whether the customer
has a timer for switching off the
internet connection and check
that the time interval setting is
not too short
Check the system manage-
ment settings in Fronius So-
lar.web (actual Wpeak for each
inverter and threshold value)
and check shading
