Problem LCD/LED/Buzzer Explanation / Possible cause 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
displayed as 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
check if input voltage range
setting is correct
(Appliance
→
Wide)
When the unit is
turned on, internal
relay is switched on
and off repeatedly. LCD display and LEDs
are flashing.
Battery is disconnected.
Check if battery wires are

Fault code 07
Overload error. The inverter is
overload 110% and time is up. Reduce the connected load by
switching off some equipment.
Fault code 05
Output short circuited.
Check if wiring is connected
well and remove abnormal
load.
Internal temperature of inverter
component is over 90 ℃.
Check whether the air flow of
the unit is blocked or whether
the ambient temperature is too
high.
Fault code 02
Fault code 03
Battery is over charged. Return to repair center.
The battery voltage is too high.
Check if spec and quantity of
batteries are meet
requirements.
Fault code 01 Fan fault Replace the fan.
Fault code 06/58
Output abnormal (Inverter
voltage below than 202Vac or is
higher than 253Vac)
1. Reduce the connected load.
2. Return to repair center
Fault code
08/09/53/57
Internal components failed. Return to repair center.
Fault code 51 Over current or surge.
Restart the unit, if the error
happens again, please return to
repair center.
Fault code 52 Bus voltage is too low.
Fault code 55 Output voltage is unbalanced.
Fault code 56
Battery is not connected well or
fuse is burnt.
If the battery is connected well,
