LCD/LED/Buzzer
The battery voltage is too low
(<1.91V/Cell)
1. The battery voltage is far too
low. (<1.4V/Cell)
2. Internal fuse tripped.
Input protector is tripped
Insufficient quality of AC power.
(Shore or Generator)
Set "Solar First" as the priority of
output source.
Battery is disconnected.
Overload error. The inverter is
overload 110% and time is up.
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.
Output short circuited.
Temperature of internal converter
component is over 120°C.
Internal temperature of inverter
component is over 100°C.
Battery is over-charged.
The battery voltage is too high.
Fan fault
Output abnormal (Inverter voltage
below than 190Vac or is higher
than 260Vac)
Internal components failed.
Over current or surge.
Bus voltage is too low.
Output voltage is unbalanced.

FlinFuzion Solar Hybrid Inverter
What to do
1. Re-charge battery.
2. Replace battery.
1. Contact repair center for
replacing the fuse.
2. Re-charge battery.
3. Replace battery.
Check if AC breaker is tripped
and AC wiring is connected
well.
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.
Check if battery wires are
connected well.
Reduce the connected load by
switching off some
equipment.
Reduce the number of PV
modules in series or the
connected load.
Check if wiring is connected
well and remove abnormal
load.
Check whether the air flow of
the unit is blocked or whether
the ambient temperature is
too high.
Return to repair center.
Check if spec and quantity of
batteries are meet
requirements.
Replace the fan.
1. Reduce the connected
load.
2. Return to repair center
Return to repair center.
Restart the unit, if the error
happens again, please return
to repair center.
