Status diagnostics and troubleshooting
Status code dis-
play
The inverter performs a system self-diagnosis that automatically detects many
faults that may occur and shows them on the display. This means you are
promptly made aware of malfunctions in the inverter or the photovoltaic system,
or of any installation or operating faults.
If the system self-diagnosis has detected a specific fault, the associated status
code will be shown on the display.
IMPORTANT! Status codes may sometimes appear briefly as a result of the in-
verter's control response. If the inverter then continues working with no sign of
any problem, this means that there was no fault.
Total failure of
the display
If the display fails to come on some time after sunrise:
-
Check the AC voltage ON the inverter connections:
the AC voltage must be 230 V (+ 10 % / - 5 %)*.
* The mains voltage tolerance depends on the country setup
