List of event messages
Event message Description Type
Grid freq. too
low
The mains frequency at the inverter is less than the minimum permissible
value. Due 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
high
The mains frequency at the inverter is greater than the maximum permis-
sible value. Due to legal requirements, the inverter switches automatically
off while the error state is present.

Contact your installer if this error occurs frequently.
Grid frequency
too high (2)
After switching off the inverter cannot resume feeding because the grid
frequency exceeds the legally prescribed switch-on value of 50.05 Hz.

Contact your installer if this error occurs frequently.
Grid volt. too
low
The mains voltage at the inverter is less than the minimum permissible
value for a short period of time. Due to legal requirements, the inverter
switches automatically off while the error state is present.

Contact your installer if this error occurs frequently.
Grid volt. too
high
The mains voltage at the inverter is greater than the maximum permis-
sible value for a short period of time. Due to legal requirements, the
inverter switches automatically off while the error state is present.

Contact your installer if this error occurs frequently.
Grid volt.
(10min) too
high
The output voltage averaged over 10 minutes lies outside the permissible
tolerance range. Due to legal requirements, the inverter switches auto-
matically off while the error state is present.

Contact your installer if this error occurs frequently.
Grid DC offset
too high
The DC current portion fed into the grid by the inverter exceeds the maxi-
mum permissible value. Due to legal requirements, the inverter switches
automatically off while the error state is present.

Contact your installer.
Resid. curr.
too high
The residual current flowing from the positive or negative inputs to earth
via the photovoltaic 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 phase and neutral conductors are wrongly connected. For safety
reasons, the inverter must not feed into the grid.

Contact your installer.
FE not con-
nected
The functional earthing conductor is not connected. For safety reasons
the inverter must not feed into the grid.

Contact your installer.
Isolation er-
ror
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.

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 (derating).

Contact your installer.
Device over-
heated
Despite derating, the maximum permissible temperature has been
exceeded. 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 volt. too
high
The DC input voltage at the inverter is greater than the maximum permis-
sible value.

Switch off the main DC switch at the inverter and contact your in-
staller.
PV current too
high
The input current at the inverter exceeds the permissible value. The in-
verter limits the current to the permissible value.

Contact your installer if this message occurs frequently.
