Error description
Solution
100000
Grid_OVP
1.
Check whether Grid is abnormal.
2.
Confirm whether the grid cable connection is
normal.
3.
Restart inverter and ensure whether the fault
is existing.

Grid_UFP
100004
Phase_locked_fault
100005
BUS_OVP1
1.
Check whether the input voltage of PV1 and
PV2 ex-ceeds 550V.
2.
If the first one does not exist, restart the
inverter to see if the fault still exists. If it still
exists, please call the service center.
100007
Insulation_fault
1.
If the power on time fails in the morning, it
may be caused by wet weather.
2.
Use a multi-meter to test the impedance of
the ground to the housing. If the impedance is
not close to 0, confirm that there is a connection
problem between the ground wire and the
housing.
3.
Test the impedance of ground to PV+ / PV- /
BAT+ / BAT- with a multi-meter. If the imped-
ance is less than 25 Kῼ, check whether the
connection of each port is correct.
4.
Confirm to install the inverter according to the
manual.
5.
Restart the inverter to see if the fault still
exists. If it still exists, contact customer service.
100008
GFCI_fault
Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
100009
Leakage current test failure
100010
Grid relay fault
1.
Confirm to install the inverter according to the
manual.
2.
Restart the inverter to see if the fault still exists.
If it still exists,please call the service center.
100011
Over_Temperature
1.
Try to lower the ambient temperature.
2.
Confirm to install the inverter according to the
manual.
3.
After the inverter is powered off and waiting for
30 minutes, then restart it. If the fault still exists,
please call the service center.
100012
PV_Reverse
Check whether the battery connection
is reversed.
100013
BAT_Reverse
Check whether the battery connection is reversed.
