Tab. 3: Event codes
If the inverter enters shutdown mode due to an event shown above, the Warning/Alarm LED will light
up. The Troubleshooting table describes actions to be taken for the most common events.
Troubleshooting
Event code Causes Recommended measures
Grid overvoltage The grid voltage exceeds its
permissible range or the grid is not
available.
If the alarm occurs occasionally, there may be a
fault in the power supply system. No additional
measures are required.
If the alarm occurs repeatedly, contact your local
power company. If the fault is not due to the grid,
check the grid settings of the inverter using the
KOSTAL PIKO CI app.
If the alarm persists for a long time, check whether
the AC line circuit breaker / AC terminals are dis-
connected or the grid power supply has failed.
Grid undervoltage
Grid missing
Grid overfrequency
Grid underfrequency
Grid error
PV overvoltage The input voltage of the PV
modules exceeds the permissible
range of the inverter.
Check the number of PV modules and adjust them
if necessary.
PV undervoltage The input voltage of PV modules
is below the preset protection
value of the inverter.
When the intensity of the sunlight is low, the
voltage of the PV modules drops. No action is
required.
If the intensity of sunlight is high, check for short
circuits, open circuits, etc. in the PV strings.
PV insulation fault There is a short circuit between
PV strings and protective earth.
PV strings are installed in a persis-
tently humid environment.
If the alarm occurs accidentally, the external circuits
(PV strings) will supply irregular values. The inverter
automatically returns to normal operation after the
fault has been corrected.
If the alarm occurs repeatedly or lasts for a long
time, check whether the insulation resistance of the
PV strings to earth is too low.
