012
Leakage current
over-current.
The leakage current
exceeds inverter
allowable upper limit.
1. Check the PV strings for ground fault.
2. If the fault occurs repeatedly, contact
SUNGROW.
014
10-minute grid
over-voltage.
The average grid
voltage in 10 minutes
exceeds the
permissible range.
1. Check whether the selected country code
is correct.
2. Wait a moment for inverter recovery.
3. Check the voltage of the grid. If the grid
voltage exceeds the permissible range of
inverter protection parameters, ask utility
grid company for solution.
4. If the fault occurs repeatedly, contact
SUNGROW.
015
Grid over-voltage
The grid voltage
exceeds the protective
value, which is higher
than the protective
value of error 002.
(stage II)
1. Check the model of the AC cables.
2. Wait a moment for inverter recovery.
3. If the grid voltage exceeds the
permissible range, ask utility grid company
for solution.
4. If the fault occurs repeatedly, contact
SUNGROW.
016
The bus voltage or
power is high.
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
SUNGROW.
019
Bus transient
over-voltage.
The transient bus
voltage exceeds
inverter allowable
upper limit.
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
SUNGROW.
020
Bus over-voltage.
The bus voltage
exceeds inverter
allowable upper limit.
1. Wait a moment for inverter recovery.
2. If the fault occurs repeatedly, contact
SUNGROW.
021
PV1 input over-current.
Check the layout and the wiring of PV1
input.
022
PV2 input over-current.
Check the layout and the wiring of PV2
input.
028
PV1 reverse
connection.
Check the cable connections of PV1.
029
PV2 reverse
connection.
Check the cable connections of PV2.
036
The temperature of
radiator is too high.
1. Check whether the ambient temperature
shown on the screen is too high. Wait a
