Trouble Shooting
Problem
LCD/LED/Buzzer
Explanation
What to do
Unit shuts down
Automatically during
startup process.
LCD/LEDs and buzzer will
be active for 3 seconds
and then complete off.
The battery voltage is too low .
(<1.91V/Cell)
1.Re-charge battery.
2.Replace battery.
No response after
power on.
No indication.
1.The battery voltage is far too
low. (<1.4V/Cell)
2.Battery polarity is connected
reversed.
1. Check if batteries and the wiring are connected
well.
2.Re-charge battery.
3.Replace battery.
Mains exist but the
unit works in battery
mode.
Input voltage is 0 on the
LCD and green LED is
flashing.
Input protector is tripped.
Check if AC breaker is tripped and AC wiring is
connected well.
Green LED is flashing.
Insufficient quality of AC power.
(Shore or Generator)
1. Check if AC wires are too thin and/or too long.
2. Check if generator (if applied) is working well or if
input voltage range setting is correct.
(UPS→Appliance)
Green LED is flashing.
Set “Battery First” or “Solar First”
as the priority of output source.
Change output source priority to Utility first.
When it’s turned on,
internal relay is
switching on and off
repeatedly.
LCD display and LEDs are
flashing
Battery is disconnected.
Check if battery wires are connected well.
Buzzer beeps
continuously and red
LED is on.(Fault code)
Buzzer beeps once
every second, and red
LED is flashing.
(Warning code)
Fault code 01
Fan fault.
1.Check whether all fans are working properly.
2.Replace the fan.
Fault code 02
Internal temperature of component
is over 100℃.
1.Check whether the air flow of the unit is blocked or
whether the ambient temperature is too high.
2.Check whether the thermistor plug is loose.
Fault code 03
Battery is over-charged.
Restart the unit, if the error happens again, please
return to repair center.
The battery voltage is too high.
Check if spec and quantity of batteries are meet
requirements.
Warning code 04
The battery voltage/SOC is too low.
1.Measure battery voltage in DC input.
2.Check battery SOC in LCD when use Li battery.
3.Recharge the battery.
Fault code 05
Output short circuited.
Check if wiring is connected well and remove
abnormal load.
Fault code 06/58
Output abnormal (Inverter voltage
is higer than 150Vac or less than
40Vac).
1.Reduce the connected load.
2. Restart the unit, if the error happens again, please
return to repair center.
Fault code 07
The inverter is overload 110% and
time is up.
Reduce the connected load by switching off some
equipment.
Fault code 08
Bus voltage is too high.
1.If you connect to a lithum battery without
communication, check whether the voltage points of
the program 19 and 21 are too high for the lithum
battery.
2. Restart the unit, if the error happens again, please
return to repair center.
Fault code 09/53/57
Internal components failed.
Restart the unit, if the error happens again, please
return to repair center.
Warning code 15
The input status is different in
parallel system.
Check if AC input wires of all inverters are
connected well.
Warning code 16
Input phase is not correct.
Change the input phase S and T wiring.
Warning code 17
The output phase not correct in
parallel.
1.Make sure the parallel setting are the same
system(sigle or paralle; 3P1,3P2,3P3).
2.Make sure all phases inverters are power on.
Warning code 20
Li battery can't communicate to the
inverter.
1.Check whether communication line is correct
connection between inverter and battery.
2.Check whether BMS protocol type is correct setting.
