List of event messages
Event message Description
Grid frequency
The grid frequency at the inverter is less than the minimum permissible value. Due
too low
to legal requirements, the inverter switches automatically off while the error state is
present.
Contact your installer if this error occurs frequently.

Grid frequency
The grid frequency at the inverter is greater than the maximum permissible value. Due
too high
to legal requirements, the inverter switches automatically off while the error state is
present.
Contact your installer if this error occurs frequently.

Grid freq. too
After switching off, the inverter cannot resume feeding because the grid frequency
high for reac-
exceeds the legally prescribed switch-on value.
tivation
Contact your installer if this error occurs frequently.

Grid voltage
The grid voltage at the inverter is less than the minimum permissible value. Due to
too low
legal requirements, the inverter switches automatically off while the error state is
present.
Contact your installer if this error occurs frequently.

Grid voltage
The grid voltage at the inverter is greater than the maximum permissible value. Due
too high to legal requirements, the inverter switches automatically off while the error state is
present.
Contact your installer if this error occurs frequently.

Grid voltage After switching off, the inverter cannot resume feeding because the grid voltage ex-
too high for ceeds the legally prescribed switch-on value.
reactivation
Contact your installer if this error occurs frequently.

Grid voltage Ø The output voltage averaged over the legally prescribed period of time exceeds the
too high
permissible tolerance range. The inverter switches automatically off while the error
state is present.
Contact your installer if this error occurs frequently.

Grid voltage Ø
The output voltage averaged over the legally prescribed period of time exceeds the
too low
permissible tolerance range. The inverter switches automatically off while the error
state is present.
Contact your installer if this error occurs frequently.

Grid current
The DC current portion fed into the grid by the inverter exceeds the maximum permis-
DC Offset too
sible value. Due to legal requirements, the inverter switches automatically off while
high
the error state is present.
Contact your installer.

Resid. curr.
The residual current flowing from the positive or negative inputs to earth via the pho-
too high
tovoltaic modules exceeds the maximum permissible value. Due to legal requirements,
the inverter switches automatically off while the error state is present.
Contact your installer.

L and N swapped The live and neutral conductors are wrongly connected. For safety reasons the invert-
er must not feed into the grid.
Contact your installer.

FE not con-
The protective earth is not connected. For safety reasons the inverter must not feed
nected
into the grid.
Contact your installer.

Isolation er-
The insulation resistance between the positive or negative input and earth is less than
ror
the permissible value. For safety reasons the inverter must not feed into the grid.
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.
Contact your installer.

Device has
Despite power reduction, the maximum permissible temperature has been exceeded.
overheated
The inverter feeds no power into the grid until the maximum 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
The input voltage at the inverter is greater than the maximum permissible value.
high
Switch off the main DC switch at the inverter and contact your installer.
