Displaying status
codes 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 and 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.
Total failure of the
display The display can be supplied with power in three different ways. The display will only remain
dark if all three methods fail. In this case:
-
Check the AC voltage on the inverter connection sockets:
The AC voltage must be 220/230 V (+10% / -5%) or 380/400 V (+10% / -5%).
- Check the DC voltage of the solar modules on the connection sockets of the inverter:
The DC voltage must exceed 180 V.
- Check the DC voltage of the battery on the connection sockets of the inverter: The DC
voltage must exceed 120 V.
Class 1 status
codes Class 1 status codes generally only arise momentarily and are caused by the public grid.
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 subse-
quently checked during the stipulated monitoring period. If no further problem has been de-
tected 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 in-
creased in line with the national guidelines.
Status codes –
Class 3 Class 3 includes status codes that may occur while feeding energy into the grid, but gen-
erally do not cause the process to be interrupted for any length of time.
IMPORTANT! Status codes may sometimes appear briefly as a result of the inverter's con-
trol response. If the inverter then continues working with no sign of any problem, this
means that there was no fault.
Code Description Behaviour Remedy
102 AC voltage too high
Following careful testing and
when the grid conditions are
within the permissible range
again, the inverter will resume
feeding energy into the grid.
