Event message Description Type
Power reduction due to
temperature
The inverter reduces it output power because the
maximum permissible temperature has been
reached.
1. Check whether the installation conditions are ful-
filled.
2. Contact your installer if this error occurs fre-
quently.
PV current too high
The input current at the inverter exceeds the per-
missible value. The inverter limits the current to the
permissible value.
u Contact your installer if this alarm occurs fre-
quently.
PV voltage too high
The input voltage applied on the inverter exceeds
the permissible value.
u Switch off the DC load-break switch of the
inverter and notify your installer.
Reading CountryCode
failed
The inverter could not correctly read out the
country setting from the memory.
u Notify your installer.
Residual current too high
The fault current that flows from the plus or minus
input via the PV generators exceeds the permissible
value. Pursuant to statutory regulations, the
inverter switches off automatically as long as this
fault is pending.
u Notify your installer.
RS485 Gateway activated
No communication with the inverter possible via
the RS485 interface.
u Disconnect the inverter from the grid and reset it
(AC reset).
u Have your installer carry out this operation.
Self test failed
An error occurred during the self-test, the self-test
has been aborted.
u Notify your installer if
n the self-test has been aborted repeatedly at dif-
ferent times a day due to an error and
n grid voltage and frequency were definitely within
the limit values of the country setting.
