Error description
Solution
100035
INV_OTP
1.
Try to lower the ambient temperature.
2.
Make sure that the inverter is installed according
to the manual and there is no shelter around the
inverter.
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.
100036
INV_OVP
The effective value of grid voltage exceeds the
maximum protection value of national standard
voltage.
100037
INV_UVP
1.
Whether the off grid output terminal is short
circuited or has impact load.
2.
Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
100038
Output_DC_
over_current
Restart the inverter to see if the fault still exists. If
it still exists, please call the service center.
100039
INV_OCP
1.
Check whether the off grid output terminal is
overloaded, short circuited or has impact load.
2.
Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
100040
INV_HW_OCP
Restart the inverter to see if the fault still exists. If it
still exists, please call the service center.
100041
Output_DC_
over_voltage
100042
Output_short
1.
Use a multimeter to test the impedance of the off
grid output. If it is small, check whether the wiring
is correct.
2.
Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
100043
Output_overload
1.
Check whether the load exceeds the rated power.
2.
Restart the inverter to see if the fault still exists. If
it still exists, please call the service center.
110000
Bat over-voltage alarm
Check that the actual battery voltage is 10V higher
than the battery charging cut-off voltage
110001
Bat under-voltage alarm
Check that the actual battery voltage is 10V higher
than the battery discharging cut-off voltage
110002
output_overload_alarm
Check whether the load exceeds 0.95 of the rated
power
110003
abnormal_temperature_
sensor
Restart the inverter to see if the fault still exists. If
it still exists, please call the service center.
110004
dc_power_alarm
1.
Check whether the total power of the battery
and PV is less than the load power.
2.
Restart the inverter to see if the fault still exists.
If it still exists, please call the service center.
