Fault
Code
Description Troubleshooting
040
AC or DC overcurrent
fault, or DC overvoltage
fault Wait for inverter recovery.
If the fault occurs repeatedly, contact
Sungrow.
041
Current leakage
sampling channel
failure
Wait for inverter recovery.
If the fault still occurs, contact Sungrow.
042 Current imbalance.
If the fault occurs repeatedly, contact
Sungrow.
043
ambient temperature
falls below -25
o
C
Disconnect and stop the inverter. Wait for
ambient temperature to rise within the
permissible range and then restart inverter.
044
DC/AC inversion circuit
fault Wait for inverter recovery.
If the fault still occurs, contact Sungrow.
045 PV boost circuit fault
Wait for inverter recovery.
If the fault still occurs, contact Sungrow.
047
PV configuration mode
set on the display is not
in accordance with the
reality.
Disconnect the inverter.
Re-select PV configuration mode and
re-connect PV strings. For more detailed
information please refer to “6.3 PV Array
Connection”.
048
Phase-R current
sampling channel fault.
Wait for inverter recovery.
If the fault occurs repeatedly, contact
Sungrow.
049
Phase-S current
sampling channel fault.
050
Phase-T current
sampling channel fault.
051
Hardware Overvoltage/
Overcurrent protection
Wait for inverter recovery.
If the fault occurs repeatedly, contact
Sungrow.
070 Fans failure
Stop inverter, disconnect the power supply
and remove the broken fan
071 AC side SPD fault Replace SPD if necessary;
Contact Sungrow.
072 DC side SPD fault
073 Fuse has blown out
Stop inverter, disconnect the power supply
and replace the fuse;
Contact Sungrow.
074
LCD communication
fault
A fault has occurred in the internal
communication of the inverter. However,
the inverter continues feeding into the
grid.
Contact Sungrow.
075
Solar irradiation is not
sufficient for inverter
operation.
Wait for sufficient irradiation.
If this fault recurs when irradiation is
sufficient, check the PV system design and
adjust the connection of PV inputs.
076 PV overload
Check the PV system design and adjust the
connection of PV inputs.
