EG4 6500 - Troubleshooting Guide and Codes

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 reversed.
1. Check if batteries and the
wiring are connected
corrected and securly.
2. Re-charge 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 correctly.
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 if
input voltage range setting is
correct. (UPS→Appliance)
Green LED is flashing.
“Solar First” is set as the priority
energy source for loads.
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 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 repair center.
The battery voltage is too high.
Check if spec and quantity
of batteries meet minimum
design requirements.
Fault code 01
Fan fault
Replace the fan.
Fault code 06/58
Output abnormal (Inverter
voltage is below 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 51
Over current or surge.
Check to ensure you are
getting proper PV voltage to
the inverter.
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.
