Grid failure overvoltage L1
Shutdown because the grid voltage on phase
Lx is outside the set limit value (2nd level up to
5th level of grid monitoring). The limit value is
specified by the respective country-specific
standard.
Check grid voltage
at the device termi-
nal Lx. Check setting
values in the param-
eters menu. Has ev-
erything been set
up correctly and is
the voltage within
the set limit values?
Check connection/
cabling!

DC overvoltage 1
PV voltage above permissible limit values.
Re-wire PV mod-
ules. Contact your
authorised electri-
cian.

DC overvoltage 2
PV voltage above permissible limit values.
Re-wire PV mod-
ules. Contact your
authorised electri-

Relay control fault
The enable signal for the relay control is read
back. Shutdown occurs if the level is incorrect.
Notify KACO Ser-
vice!

128
Internal memory error 1
Write or read access to the internal RAM of
the DSP was erroneous. The device only feeds
into the grid again the next day or following a
reset.
Disconnect device
on the DC side and
wait 1 minute, then
switch on again.
B
129
Voltage-dependent power
reduction
Yes, if the function P(U) sets the power level
according to the specified parameters subject
to the AC voltage.
This functionality
may, for example,
be requested by the
grid operator. If
there is no request,
the function can be
deactivated.
B
148
External memory error 1
The device has permanent internal memory
for the purpose of, for example, storing the
hardware used. Operation parameters are de-
duced from this.
Disconnect AC and
DC, wait 1 minute
and switch on again.
B
150
Protective shutdown drop
reference ADC
Internal protective function in order to adhere
to the required measurement accuracy.
Disconnect AC and
DC, wait 1 minute
and switch on again.
