26 / 30
F-104
Inverter grid-connected
relay fault
Contact Customer service.
F-105
Grid frequency fault
1. If power grid frequency returns to normal, the inverter
will restore the grid connection automatically.
2. If error message still exists, contact Customer service.
F-106
Grid voltage fault
1. Turn off DC switch, remove AC connector, measure the
voltage between fire line and the zero line, then check if it
is consistent with the grid-connected specification of
inverter.
2. Inconsistent, check the grid layout.
3. Consistent, connect the AC connector, turn on DC
Switch, inverter will restore the grid connection
automatically.
4. If error message still exists, contact Customer service.
F-107
DC component over
range
1. Restart inverter.
2. If error message still exists, contact Customer service.
F-108
Current sensor fault
1. Wait until inverter restores normal work.
2. If error message still exists, contact Customer service.
F-110
Leakage current
detection unit fault
1. Check if there is any PV cable breakage.
2. Check if the PV modules grounding improperly.
3. Restart inverter.
4. If error message still exists, contact Customer service.
F-111
Leakage current fault
1. Check if PV strings grounding properly.
2. If error message still exists, contact Customer service.
F-112
DC insulation fault
1. Check if inverter grounding properly.
2. Check if the positive and negative poles of PV modules
are short out to the PE cable.
3. Wait until inverter restores normal work.
4. If error message still exists, contact Customer service.
F-113
Leakage current
detection consistency
error (Major)
1. Restart the inverter.
2. If error message still exists, contact Customer service.
F-114
Frequency detection
consistency error (Major)
1. Restart the inverter.
2. If error message still exists, contact Customer service.
F-115

detection consistency
error (Major)
F-116
Leakage current
detection consistency
error (Minor)
F-117
Frequency detection
consistency error (Minor)
