SAFETY INSTRUCTIONS

WARNING: This chapter contains important safety and operating instructions. Read and
keep this manual for future reference.

1.Beforeusingtheunit,readallinstructionsandcautionarymarkingsontheunit,thebatteries
andallappropriatesectionsofthismanual.
2.CAUTION‐‐Toreduceriskofinjury,chargeonlydeep‐cycleleadacidtyperechargeablebatteries.
Othertypesofbatteriesmayburst,causingpersonalinjuryanddamage.
3.Donotdisassembletheunit.Takeittoaqualifiedservicecenterwhenserviceorrepairis
required.
4.Toreduceriskofelectricshock,disconnectallwiringsbeforeattemptinganymaintenanceor
cleaning.
Turningofftheunitwillnotreducethisrisk.
5.Warning!!Onlyqualifiedservicepersonsareabletoservicethisdevice.Iferrorsstillpersist
afterfollowingtroubleshootingtable,pleasesendthisinverter/chargerbacktolocaldealeror

TROUBLE SHOOTING
Problem
LCD/LED/Buzzer Possible cause What to do
Unit shuts down
automatically
during startup
process
LCD/LEDs and
buzzer will be
active then
complete off
The battery voltage is too
low
1. Re-charge battery.
2. Replace battery
No response after
power on
No indication 1. The battery voltage is
far too low.
2. Internal fuse tripped
1. Contact repair center for
replacing the fuse.
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.
LED is flashing Insufficient quality of AC power 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. (UPS Appliance)
Change output source priority
to Utility first
When the unit is
turned on, internal
relay is switched on
and off repeatedly
LCD display and
LED sare flashing
Battery is disconnected
Check if battery wires are
connected well
Buzzer beeps
continuously and
red LED is on.
Fault code 01
Fan fault Replace the fan
Fault code 02 Internal temperature of
inverter component is over
100°C.
Check whether the air flow of
the unit is blocked or whether
the ambient temperature is
too high.
Fault code 03
The battery voltage is too
high
Check if spec and quantity of
batteries are meet
requirements
Battery is over-charged. Return to repair center
Fault code 05 Output short circuited.
Check if wiring is connected
well and remove abnormal
load.
Fault code 07
Overload error. The
inverter is overload 110%
and time is up.
Reduce the connected load by
switching off some
equipment.
If PV input voltage is
higher than specification,
the output power will be
derated. At this time, if
connected loads is higher
than derated output
power, it will cause
overload.
Reduce the number of PV
modules in series or the
connected load.

Buzzer beeps
continuously and
red LED is on.
Fault code 06/15
Output abnormal (Inverter
voltage below than 190Vac
or is higher than 260Vac)
1. Reduce the connected
load.
2. Return to repair center
Fault code
08/09/12/14
Internal components failed
Return to repair center
Fault code 10
Over current or surge.
Restart the unit, if the error
happens again, please return
to repair center
Fault code 11
Bus voltage is too low.
Fault code 13
Output voltage is
unbalanced.
Fault code 16
PV input voltage is beyond
the specification. Reduce the number of PV
