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, contact service.
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, contact service.
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 ex-
ists, contact service.
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, contact service.
110005
battery_stops_
running_alarm
1. If the battery is not connected, use a multimeter to meas-
ure whether there is voltage at the battery terminal.
2. Restart the inverter to see if the fault still exists. If it still
exists, contact service.
110006
over_temperature_alarm
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 machine.
3. After the inverter is powered off and waiting for 30
minutes, then restart it. If the fault still exists, contact ser-
vice.
