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.
Utility/AC input is
available, but the
unit only pulls
energy from the
batteries when in
utility/AC input as
priority source.
Input voltage is
displayed as 0 on the
LCD and green LED is
flashin
g
.
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.
(Utility 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. (UPSÆAppliance)
Green LED is flashing.
You have set “Solar First” 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
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.
Temperature of internal converter
component is over 248
°F (120°C).
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 212
°F (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 meet
requirements.
Fault code 01 Fan fault Replace the fan.
Fault code 06/58
Output abnormal (Inverter voltage
below than 190Vac or is higher
than 260Vac)
1. Reduce the connected
load.
2. Return to repair center
Fault code
08/09/53/57
Internal components failed. Return to repair center.
Fault code 10
Surge
Restart the unit, if the error
happens again, please
return to repair center.
Fault code 12 DC/DC over current or surge.
Fault code 51 Over current or surge.
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.
Fault code 11
Solar input voltage is more than 500V.
Reduce solar input below
500V in all temperatures
