cannot be detected.
064
INV over-voltage fault in the
off-grid mode.
Wait 5 minutes for inverter recovery
or restart the system.
065
INV under-frequency fault in the
off-grid mode.
(default value: 47 Hz)
066
INV over-frequency fault in the
off-grid mode.
(default value: 52 Hz)
067
Temporary grid over-voltage in
the off-grid mode.
(default value: 500 V)
083 Fan2 abnormal speed warning.
1. Check if the fan is blocked.
2. Restart the system.
084
Warning for reverse cable
connection of the Sungrow
Meter.
1. Check whether the power cable
connections are correct.
2. For Sungrow single-phase meter,
check whether the CT clamp of the
1-phase sensor is correctly placed.
Refer to “7.4.1 Meter Installation
and Connection”.
100
INV hardware over-current fault.
The AC current exceeds the
protective value.
Wait 5 minutes for inverter recovery
or restart the system.
101
Grid over-frequency.
(default value: 52 Hz)
Check the grid frequency.
102
Grid under-frequency.
(default value: 47 Hz)
106
Earth fault.
Neither the PE terminal on the
AC connection block nor the
second PE terminal on the
enclosure is reliably connected.
1. Check whether there is a reliable
grounding connection.
2. If there is access to the ground,
and the fault still exists, please
contact SUNGROW for a solution.
3. Check whether the L-line and
N-line are connected correctly.
107
DC injection over-voltage fault in
the off-grid mode.
The DC injection of INV voltage
exceeds the upper limit.
The inverter will recover once the
DC injection voltage falls below the
recovery value.
200
Bus hardware over-voltage fault.
The bus voltage exceeds the
protection value.
Wait 5 minutes for inverter recovery
or restart the system.
201 Bus under-voltage fault.
202
PV hardware over-current fault.
The PV1 or PV2 current exceeds
the protective value.
