continuously and red
LED is on.(Fault code)
Buzzer beeps once
every second, and red
LED is flashing.
(Warning code)
2.Replace the fan.
Fault code 02
Internal temperature of component
is over 100℃.
1.Check whether the air flow of the unit is blocked or
whether the ambient temperature is too high.
2.Check whether the thermistor plug is loose.
Fault code 03
Battery is over-charged.
Restart the unit, if the error happens again, please
return to repair center.
The battery voltage is too high.
Check if spec and quantity of batteries are meet
requirements.
Warning code 04
The battery voltage/SOC is too low.
1.Measure battery voltage in DC input.
2.Check battery SOC in LCD when use Li battery.
3.Recharge the battery.
Fault code 05
Output short circuited.
Check if wiring is connected well and remove
abnormal load.
Fault code 06/58
Output abnormal (Inverter voltage
is over 150Vac or below 40Vac).
1.Reduce the connected load.
2. Restart the unit, if the error happens again, please
return to repair center.
Fault code 07
The inverter is overload 110% and
time is up.
Reduce the connected load by switching off some
equipment.
Fault code 08
Bus voltage is too high.
1.If you connect to a lithum battery without
communication, check whether the voltage points of
the program 19 and 21 are too high for the lithum
battery.
2. Restart the unit, if the error happens again, please
return to repair center.
Fault code 09/53/57
Internal components failed.
Restart the unit, if the error happens again, please
return to repair center.
Warning code 15
The input status is different in
parallel system.
Check if AC input wires of all inverters are
connected well.
Warning code 16
Input phase is not correct.
Change the input phase S and T wiring.
Warning code 17
The output phase not correct in
parallel.
1.Make sure the parallel setting are the same
system(sigle or paralle; 3P1,3P2,3P3).
2.Make sure all phases inverters are power on.
Warning code 20
Li battery can't communicate to the
inverter.
1.Check whether communication line is correct
connection between inverter and battery.
2.Check whether BMS protocol type is correct setting.
Fault code 51
Over current or surge.
Restart the unit, if the error happens again, please
return to repair center.
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 60
Negative power fault
1.
Check whether the AC output connected to the grid
input.
2.
Check whether Program 8 settings are the same for
all parallel inverters
3.
Check whether the current sharing cables are
connected well in the same parallel phases.
4.
Check whether all neutral wires of all parallel units
are connected together.
5.
If problem still exists, contact repair center.
Fault code 80
CAN fault
1.
Check whether the parallel communication cables
are connected well.
2.
Check whether Program 23 settings are right for the
parallel system.
3.
If problem still exists, contact repair center
Fault code 81
Host loss
Note:
To restart the inverter, all power sources need to be disconnected. After the LCD screen light is off, only use the battery to
restart the inverter.
