Status diagnostics and troubleshooting

Status code dis- The inverter performs a system self-diagnosis that automatically detects many faults that
play 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 inverter'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 If the display fails to come on some time after sunrise:
the display -

Class 1 status Class 1 status codes generally only arise momentarily and are caused by the public grid.
codes
Example: The grid frequency is too high and the inverter may not feed any energy into
the grid owing to a standard. There is nothing wrong with the device.
The initial response of the inverter is to disconnect itself from the grid. The grid is sub-
sequently checked during the stipulated monitoring period. If no further problem has
been detected by the end of this period, then the inverter will resume feeding energy into
the grid.
The GPIS SoftStart function is activated according to the country setup:
After cutting out due to an AC error, the output power of the inverter is continuously
increased in line with the national guidelines.

Class 3 status Class 3 includes status codes that may occur while feeding energy into the grid, but gen-
codes erally do not cause the process to be interrupted for any length of time.
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
Behaviour
Following careful testing and
when the grid conditions are

again, the inverter will resume
feeding energy into the grid.
