Event message
Description
Type
Data acceptance
failed
One setting, e.g. during commissioning, has failed,
as it was not correctly transmitted.
Repeat the setting.
Inform your installation company if the fault
persists.
Grid
islanding
detected
There is no grid voltage present (inverter running
independently). For safety reasons, the inverter
must not feed into the grid and switches off while
the error is present (dark display).
Contact your installer if this error occurs fre-
quently.
PE not
connected
The protective earth is not connected. For safety
reasons, the inverter must not feed into the grid.
Contact your installer.
Residual cur-
rent too high
The residual current flowing from the plus or minus
inputs to the earth via the photovoltaic modules ex-
ceeds the maximum permissible value. Due to legal
requirements, the inverter switches off automati-
cally for as long as the error state exists.
Contact your installer.
Faulty function of
boost converter
An internal component of your inverter is faulty. The
inverter does not feed or feeds with reduced power
into the mains network.
Contact your installer.
Device over-
heated
Despite derating, the maximum permissible tem-
perature 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 satis-
fied.
2. Contact your installer if the message occurs
frequently.
Boost converter
has wrong HW
version.
The inverter cannot recognise an internal component
or is not compatible with the other components. The
inverter cannot feed into the mains network.
Contact your installer.
Boost converter
not connected
The connection to the internal components is inter-
rupted. The inverter does not feed into the mains
network.
Contact your installer
Boost converter
defective
The boost converter is defective; the inverter is not
feeding into the grid or is feeding at reduced power.
Contact your installer.
Boost converter
not detected
Contact your installer.
Internal Info
Contact your installer if the message occurs
frequently.
Internal
warning
Contact your installer if the message occurs
frequently.
Internal Error
Contact your installer if the message occurs
frequently..
Insulation
error
The insulation resistance between the plus or minus
inputs and earth is less than the permissible value.
For safety reasons, the inverter must not feed into
the grid.
Contact your installer.
No branding
The inverter has wrong or faulty device data. It can
therefore not feed into the mains network.
Contact your installer.
L and N swapped
The live and neutral conductors are wrongly con-
nected. For safety reasons, the inverter must not
feed into the grid.
Contact your installer.
Faulty country
setting
An inconsistency exists between the selected country
settings and those stored in memory.
Contact your installer.
Country param-
eter invalid
The inverter cannot feed into the mains network
because it does not have valid parameters.
Contact your installer.
Reduced perfor-
mance due to
temperature
The power inverter is reducing its output, as the maxi-
mum permitted temperature has been reached.
1. Check that the installation conditions are satis-
fied.
2. Contact your installer if the message occurs
frequently.
Reading of the
country setting
faulty
The inverter could not correctly read the country
selected from memory.
Contact your installer
Fan faulty
The internal fan of the inverter is faulty. In certain situ-
ations the inverter will feed less power into the grid.
Contact your installer.
Event message
Description
Type
Grid frequency
too high for
reactivation
After switching off, the inverter cannot resume
feeding because the grid frequency exceeds the
legally prescribed switch-on value.
Contact your installer if this error occurs frequently.
Grid frequency
too low for re-
activation
After switching off, the inverter cannot resume
feeding because the grid frequency exceeds the
legally prescribed switch-on value.
Contact your installer if this error occurs frequently.
Grid frequency
too high
The grid frequency at the inverter is greater than
the maximum permissible value. Due to legal re-
quirements, the inverter switches off automatically
for as long as the error state exists.
Contact your installer if this error occurs frequently.
Grid frequency
too low
The grid frequency at the inverter is less than the
minimum permissible value. Due to legal require-
ments, the inverter switches off automatically for as
long as the error state exists.
Contact your installer if this error occurs frequently.
Network relay
defective
The inverter has detected that a network relay is faulty
and therefore does not feed into the mains network.
Contact your installer.
Grid voltage
too low for re-
activation
After switching off, the inverter cannot resume
feeding because the grid voltage exceeds the
legally prescribed switch-on value.
Contact your installer if this error occurs frequently.
Grid voltage Ø
too high
The output voltage averaged over the legally
prescribed period of time exceeds the permissible
tolerance range. The inverter switches off automati-
cally for as long as the error state exists.
Contact your installer if this error occurs frequently.
Grid voltage Ø
too low
The output voltage averaged over the legally pre-
scribed period of time exceeds the permissible toler-
ance range. The inverter switches off automatically for
as long as the error state exists.
Contact your installer if this error occurs frequently.
Grid voltage
too high
The grid voltage at the inverter is greater than the
maximum permissible value. Due to legal require-
ments, the inverter switches off automatically for as
long as the error state exists.
Contact your installer if this error occurs frequently.
Grid voltage
too high for
reactivation
After switching off, the inverter cannot resume
feeding because the grid voltage exceeds the
legally prescribed switch-on value.
Contact your installer if this error occurs frequently.
BCONV over-tem-
perature
The maximum permissible boost converter tem-
perature 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 satis-
fied.
2. Contact your installer if the message 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.
Correct the time under
Settings/Time/
Date
.
No connection to
the energy meter
There is no or no correct communication link between
the inverter and the energy meter (or the PowerStor-
age system).
Inform your installation company to have the
connection checked.
No connection to
PowerStorage
There is no or no correct communication link between
the inverter and the energy meter (or the PowerStor-
age system).
Inform your installation company to have the
connection checked.
