Event code Causes Recommended measures
Leakage current error The insulation resistance to earth
on the input side decreases during
inverter operation, resulting in too
high a residual current.
Check the insulation resistance to earth for the PV
strings. If a short circuit has occurred, correct the
error.
If the insulation resistance to earth in a rainy
environment is less than the default value, set the
insulation resistance protection to SE Touch.
Weak PV irradiation PV strings have been covered for
a long time.
PV strings deteriorate.
Check whether the PV string is covered.
If the PV string is clean and not covered, check if
the PV modules are ageing or if the performance
has deteriorated.
PV string error The cables of the PV strings were
connected the wrong way round
during inverter installation.
Check that the PV string cables are correctly
connected. If they are connected the wrong way
round, connect the cables correctly.
BUS undervoltage An unusual internal imbalance in
relation to the energy control was
caused by the PV strings, which
triggered a major change in work-
ing conditions in the grid.
If the alarm occurs occasionally, the inverter can
automatically return to normal operation after the
fault has been corrected.
If the alarm occurs repeatedly, contact your sup-
port team for technical assistance.
BUS overvoltage
Reverse polarity strings
DC booster error
EEPROM error EEPROM component damaged Please contact your support team. Replace the
monitoring card.
Zero power generation and yellow
alarm light, which lights up in the
remote monitoring system
Communication failure If a data logger is being used, modern or other-
wise, please restart the data logger. If the error still
occurs, contact your support team.
Remote monitoring system indi-
cates zero power generation
Communication failure If a data logger is being used, modern or other-
wise, please restart the data logger.
If the error still occurs, contact your support team.
Remote monitoring system shows
no output voltage
DC switch to OFF Check if the DC switch is damaged, and if not, turn
it ON.
If the error still occurs, contact your support team.
Grid error Fault in the power supply system Wait until power is restored.
DC switch to OFF Turn the DC switch to ON. If the DC switch trips
frequently, contact your support.
Master connection lost Connection between slave and
master inverter is interrupted.
Check whether the communication line to the mas-
ter inverter has been interrupted.
If the error still occurs, contact your support team.
Check the communication settings in the KOSTAL
PIKO CI app.
