TROUBLE SHOOTING
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
(UPSAppliance)
Green LED is flashing.
Set Solar power as the priority of
output source
Change output source priority
to Utility first.
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
connected well.
Buzzer beeps
continuously and
red LED is on.
Fault code 07.
Overload error. The inverter is
loaded with more than 110% load
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.
Temperature of internal converter
component is over 120°C.
Check whether the air flow of
the unit is blocked or whether
the ambient temperature is
too high.
Fault code 02.
Internal Inverter component over
100°C
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.
Output abnormal (Inverter voltage
below than 190Vac or is higher
than 260Vac)
1. Reduce the connected
load.
2. Return to repair center
Fault code 08.
Internal components failed.
Return to repair center
Fault code 09.
