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 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 invert-
er: The DC voltage must exceed 120 V.
Status codes –
Class 1 Class 1 status codes generally only arise momentarily and are caused by the pub-
lic 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 subsequently checked during the stipulated monitoring period. If no further
problem has been detected by the end of this period, then the inverter will re-
sume 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 continu-
ously increased in line with the national guidelines.
Code Description Behaviour Remedy
102 AC voltage too high
Following careful testing
and when the grid condi-
tions are within the per-
missible range again, the
inverter will resume feed-
ing energy into the grid.
Check grid connections;
if this status code keeps
recurring, contact your
