Problem LCD/LED/Buzzer Explanation / Possible cause What to do
Unit shuts down
automatically during
the startup process
LCD/LEDs and buzzer
turn on for about
3 seconds before
completely shutting 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. The battery polarity is
reversed
1. Check if batteries and
the wiring are connected
correctly, matching the polarity
of the terminals
2. Re-charge battery.
3. Replace the battery.
Despite AC input is
available, the unit
continues to operate
in in battery mode
Input voltage is
displayed as 0 on the
LCD and the green LED
is flashing
Input protector is tripped
Check if the AC breaker is
tripped and if the AC wiring is
connected well
Green LED is flashing
The quality of AC power is poor
(shore or generator)
1. Check if AC wires are too
thin and/or too long
2. Check if generator (if
applies) is working well or if
the input voltage range setting
is correct (UPS
→ appliance)
The output source priority is set
to
Solar first

Battery is disconnected.
Check if battery wires are
properly connected
Buzzer beeps
continuously and red
LED is on
Fault code 07
The inverter is overloaded ≥
110% for more than the allowed
duration
Reduce the connected load by
switching off some equipment
Fault code 05
Output short circuited.
Check if the wiring is correctly
connected and remove
abnormal load
Temperature of internal
converter component is over
120°C. (Only available for
1-3KVA models)
Check whether the air flow of
the unit is blocked or whether
the ambient temperature is too
high
Fault code 02
Internal temperature of inverter
component is over 100°C
Fault code 03
Battery is over-charged. Return to service center
The battery voltage is too high
Check whether the type and
quantity of batteries specified
are met
Fault code 01 Fan fault Replace the fan
Fault code 06/58
Output abnormal (inverter
voltage is either below 190VAC
or over 260VAC)
1. Reduce the number of
connected loads
2. Return to service center
Fault code
08/09/53/57
Internal components failed Return to service center
