Code Fault Event Description
60
Current feedback into
the inverter is detected.
1. Restart the inverter.
2. Check if L1/L2/N cables are phased properly in all inverters.
3. For parallel system in split phase, make sure the red/black current
sharing cables are connected well (with screws) to all inverters.
4. If the problem remains, please contact your installer.
71
The firmware version of
each inverter is not the
same.
1.
2.
Update all inverter firmware to the same version.
Check the version of each inverter via LCD settings and make sure the
CPU versions are th same. If not, please contact your installer/retailer
to provide the 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 sharing cables are connected properly 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 retailer installer.
81 Host data loss
82
Synchronization data
loss
83
The battery voltage of
each inverter is not the
same.
1.
2.
Make sure all inverters share same the same battery bank
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 the same length and same material
type. Otherwise, please contact your installer/retailer to provide SOP to
calibrate battery voltage of each inverter.
3. If the problem still remains, please contact your retailer or installer.
84
AC input voltage and
frequency are
different.
1.
2.
Check the utility wiring conncetion and restart the inverter.
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 powered on at one time . A main breaker or disconnect is required
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 load information from LCD of
inverters. If the values are different, please check if AC input and output
cables are in the same length and material type.
3. If the problem remains, please contact your installer.
