Event message Description Type
Grid
current DC
offset too
high
The DC current portion fed into the grid by the inverter exceeds the max-
imum permissible value. Due to legal requirements, the inverter switches
automatically off while the error state is present.
u
Contact your installer.
Residual
current too
high
The residual current flowing from the positive or negative inputs to earth
via the solar modules exceeds the maximum permissible value. Due to
legal requirements, the inverter switches automatically off while the error
state is present.
u
Contact your installer.
L and N
swapped
The live and neutral conductors are wrongly connected. For safety rea-
sons, the inverter must not feed into the grid.
u
Contact your installer.
FE not con-
nected
The protective earth is not connected. For safety reasons the inverter
must not feed into the grid.
u
Contact your installer.
Insulation
error
The insulation resistance between the positive or negative input and
earth is less than the permissible value.
For safety reasons the inverter
must not feed into the grid.
u Contact your installer.
Fan faulty
The internal fan of the inverter is faulty. In certain situations the inverter
will feed less power into the grid.
u
Contact your installer.
Device
overheated
Despite power reduction, the maximum permissible temperature has
been exceeded. The inverter feeds no power into the grid until the max-
imum permissible temperature is no longer exceeded.
1. Check that the installation conditions are satisfied.
2. Contact your installer if this message occurs frequently.
PV voltage
too high
The input voltage at the inverter exceeds the permissible value.
uSwitch off the DC circuit breaker at the inverter and contact your
installer.
PV current
too high
The input current at the inverter exceeds the permissible value. The
inverter limits the current to the permissible value.
u
Contact your installer if this message occurs frequently.
Grid
islanding
detected
There is no grid voltage present (inverter running independently). For
safety reasons the inverter must not feed into the grid.
The inverter
switches off while the error is present (dark display).
u Contact your installer if this error occurs frequently.
Time/date
lost
The inverter has lost the time settings because it was disconnected from
the grid for too long. Yields cannot be stored and event messages will
have the wrong date.
u
Correct the time under Settings ▶ Time/date.
