Trouble Shooting
When there is no information displaying in the LCD, please check if PV module/battery/grid
connection is correctly connected.
NOTE: The warning and fault information can be recorded by remote monitoring software.
17-1. Fault code reference
When a fault occurs, the icon
will flash as a reminder. See below for fault codes for
reference.
Situation
Solution
Fault Event
01
DC bus voltage exceeds the upper
threshold
Disconnect AC circuit breaker first. Then,
disconnect DC circuit breaker.
Until LCD screen completely shuts down, turn on
DC breaker first. It will show “No Utility” in LCD
screen. Then, turn on AC breaker. After 300
seconds, the system will automatically connect to
the grid.
If the error message still remains, please contact
your installer.
02
DC bus voltage falls below the
lower threshold
03
DC bus voltage soft-start is time-
out
04
Inverter soft-start is time-out
05
An Inverter overcurrent event is
detected
07
An relay failure event is detected
08
DC component in the output
current exceeds the upper
threshold
11
Over-current on PV input is
detected
14
Inverter DC component exceeds
the allowable range
16
Leakage current CT failed
06
Over temperature fault
The internal temperature is higher than specified
temperature.
Leave inverter to cool down to room temperature.
If the error message still remains, please contact
your installer.
09
PV input voltage exceeds the
upper threshold
Check if the open circuit voltage of PV modules is
higher than 500Vdc.
If PV open circuit voltage is less than 500Vdc and
the error message remains, pelase contact your
installer.
10
Auxiliary power* failed
*Auxiliary power means switch
power supply.
Turn off the inverter. Then, restart the inverter. If
the error message still remains, please contact
your installer.
12
Leakage current exceeds the
allowable range
The ground voltage is too high.
Please disconnect AC breaker first and then DC
