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 sharing are
connected in all inverters.
For supporting three-phase system, make sure the sharing cables are
connected in the inverters in the same phase, and disconnected in
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 all inverter firmware to the same version.
2. Check the version of each inverter via LCD setting and make sure the
CPU versions are same. If not, please contact your instraller 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 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 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 the same length and
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 breakers
can be turned on AC input 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 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.
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 upporting three-phase system, make sure no “PAL” is set on
#28.
3. If the problem remains, please contact your installer.
