Troubleshooting
014
The average grid
voltage exceeds the
permissible range for
over 10 minutes.
Wait for inverter recovery.
If the fault occurs repeatedly, contact
Sungrow.
015
Grid impedance
exceeds inverter’s limit
Check the model of the AC cables.
Wait for inverter recovery.
If the fault occurs repeatedly, contact
Sungrow.
016
AC output overloads
Wait for inverter recovery.
If the fault occurs repeatedly, contact
Sungrow.
017
Grid voltage unbalance
Wait for inverter recovery.
If the fault occurs repeatedly, contact
Sungrow.
019
The transient bus
voltage is high.
Wait for inverter recovery.
If the fault occurs repeatedly, contact
Sungrow.
020
The bus voltage is high.
Wait for inverter recovery.
If the fault occurs repeatedly, contact
Sungrow.
021 PV
input
overcurrent
Check the PV configuration and
connection.
023
PV configuration mode
has changed during
inverter running.
Check the PV configuration;
Restart the inverter.
024
Neutral point deviation
is detected.
Inverter resumes normal operation when
deviation is within the permissible range;
If the fault occurs repeatedly, contact
Sungrow.
025
Transient unbalance of
voltage neutral point
Inverter resumes normal operation when
deviation is within the permissible range;
If the fault occurs repeatedly, contact
Sungrow.
026
Bus voltage fluctuation
This is a short-term fault. Wait for inverter
recovery
If the fault still occurs, contact Sungrow.
036
Module temperature is
too high
Check whether AC output power exceeds
the nominal power.
Check the functionality of the fans. Replace
broken fan if necessary.
Clean air outlet grills.
If the fault still occurs, contact Sungrow.
037
Ambient temperature is
too high.
038 Relay
fault
Wait for inverter recovery.
If the fault still occurs, contact Sungrow.
039
Inverter insulation
resistance fault (ISO-flt)
Wait for inverter recovery.
If the fault still occurs, contact Sungrow.
