solution.
3. If the grid frequency is within the
permissible range, contact Sungrow Service
Dept..
0014
The average grid voltage
over 10 minutes is not
within the permissible
range.
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept..
0015
Grid impedance has
exceeded inverter’s limit
1. Check AC cables for appropriate size.
2. Wait a moment for inverter recovery.
3. If the fault occurs repeatedly, contact
Sungrow Service Dept..
0016
The AC output
overloads.
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept..
0017
The inverter has
checked that there is
unbalance between the
three phase voltages.
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept..
0019
The bus voltage is
temporarily high.
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept..
0020 The bus voltage is high.
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept..
0021
Inverter has checked
that there is overcurrent
of PV1 input.
Check the layout and the wiring of PV1 input.
0022
Inverter has checked
that there is overcurrent
of PV2 input.
Check the layout and the wiring of PV2 input.
0023
PV configuration mode
has changed during
inverter running.
Check the PV input configuration mode and
restart the inverter when necessary.
0024
Inverter has checked the
deviation of neutral
point voltage.
1. Inverter will recover if the deviation value
falls below the protective limit.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept..
0025
Inverter has checked out
the unbalance of neutral
point voltage
temporarily.
1. Inverter will recover if the deviation value
falls below the protective limit.
2. If the fault occurs repeatedly, contact
Sungrow Service Dept..
0026
There is high Bus
fluctuation voltage.
1. This is a short-term fault. Wait a moment for
inverter recovery.
2. If the fault still exists, please contact
