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)
Re-charge battery.
Replace battery.
No response after
power on.
No indication.
The battery voltage is far too
low. (<1.4V/Cell)
Battery polarity is connected
reversed.
Check if batteries and the wiring are connected
well.
Re-charge battery.
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)
Check if AC wires are too thin and/or too long.
Check if generator (if applied) is working well
or if input voltage range setting is correct.
(UPS Appliance)
Green LED is flashing. Set “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.

Internal temperature of
component is over 100°C.
Check if the air flow is blocked or the ambient
temperature is too high.
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 05 Output short circuited
Check if wiring is connected well and remove
abnormal load.
Fault code 06/58
Output abnormal (Inverter
voltage below than 190Vac or
is higher than 260Vac)
Reduce the connected load.
Return to repair center
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
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, please return
to repair center.
