43
Buzzer beeps
continuously and red
LED is on. (Fault
code)
Buzzer beeps once
every second, and
red LED is flashing.
(Warning code)
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.
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. If the battery is connected well, restart the
unit. If the error happens again, 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 boot.
