9. Troubleshooting
If the device fails to function as expected, check the list of common faults below before consulting the service
center.
Situation
Solution
Fault
Code
Fault Event Description
60
Current feedback into
the inverter is
detected.
1.
Restart the inverter.
2.
Check if L/N cables are not connected reversely in all inverters.
3.
For parallel system in single phase, make sure the current sharing cables
are connected to all inverters.
For supporting three-phase system, make sure the current sharing
cables are connected to the inverters in the same phase, and
disconnected to the inverters in different phases.
4.
If the problem remains, please contact your installer.
71
The firmware version
of each inverter is not
the same.
1.
Update the firmware of all inverter to the same version.
2.
Check the version of each inverter via LCD setting and make sure the
CPU versions are the same. If not, please contact your installer to
provide the latest firmware to update.
3.
After updating, if the problem still remains, please contact your installer.
72
The output current of
each inverter is
different.
1.
Check if shared cables are connected well and restart the inverter.
2.
If the problem remains, please contact your installer.
80
CAN data loss
1.
Check if communication cables are connected well and restart the
inverter.
2.
If the problem remains, please contact your installer.
81
Host data loss
82
Synchronization data
loss
83
The battery voltage of
each inverter is not the
same.
1.
Make sure all inverters share the same groups of batteries together.
2.
Remove all loads and disconnect AC input and PV input. Then, check
battery voltage of all inverters. If the values from all inverters are close,
please check if all battery cables are in the same length and in the same
material type. Otherwise, please contact your installer to provide SOP to
calibrate battery voltage of each inverter.
3.
If the problem still remains, please contact your installer.
84
AC input voltage and
frequency are detected
different.
1.
Check the utility wiring conncetion and restart the inverter.
2.
Make sure utility starts up at same time. If there are breakers installed
between utility and inverters, please be sure all AC input breakers can be
turned on at same time.
3.
If the problem remains, please contact your installer.
85
AC output current
unbalance
1.
Restart the inverter.
2.
Remove some excessive loads and re-check the load information from
LCD of the inverters. If the values are different, please check if AC input
and output cables are in the same length and in the same material type.
3.
If the problem remains, please contact your installer.
86
AC output mode
setting is different.
1.
Switch off the inverter and check LCD setting #28.
2.
For parallel system in single phase, make sure no 3P1, 3P2 or 3P3 is set
on #28.
For supporting three-phase system, make sure no “PAL” is set on #28.
3.
If the problem remains, please contact your installer.
