90006
Grid overvoltage At least one grid phase exceeds the configured
overvoltage limit value for the configured du -
ration.
▸ Measure the voltage of all three phases
with REFUset and a True-RMS meter.
▸ Check the configured voltage limit and the
configured nominal voltage.
90007
Grid undervoltage At least one grid phase falls below the config -
ured undervoltage limit value for the config -
ured duration.
90008
Overfrequency The grid frequency exceeds the configured
limit value for the configured duration.
▸ Measure the voltage of all three phases
with REFUset and a True-RMS meter.
▸ Check the configured frequency limit and
the configured nominal frequency.
90009
Underfrequency The grid frequency falls below the configured
limit value for the configured duration.
9000B
DC link 1 The device has disconnected from the grid due
to an imbalance in the internal DC voltage and
is switched on again briefly.
▸ If this error occurs more than once, contact
REFU Service.
90011
DC link 6 The device has disconnected from the grid due
to a DC overvoltage in the input of the inverter.
As soon as the measured open-circuit voltage
is below the permitted limit value, the device
switches on again automatically.
▸ Check the DC voltage of the solar genera -
tor. The voltage must be below 1 000 VDC
for connection. The maximum DC open cir -
cuit voltage must not exceed 1 100 VDC.
90013
RCD Fail The all-current sensitive residual current
measurement has measured a relative or ab -
solute exceedance of the set limit value.
▸ Check measured value or limit value in RE -
FUset.
▸ Check the installation of the inverter.
▸ Check PE connection.
▸ Check for faulty cables (e.g. damaged insu -
lation).
▸ Check solar generator installation.
