F29
Parallel CAN Bus fault
1.When in parallel mode, check the parallel communication
cableconnection and hybrid inverter communication
address setting.
1.During the parallel system startup period, inverters will
report F29.
when all inverters are in ON status, it will disappear
automatically.
F32
PV to DC over current
1.
Check the PV panels charge to see if there are
too many panels connected to one string. If the
MPPT is overloaded, disconnect the necessary
panels from the inverter or rebuild the connection
of the panels to adjust the MPPT correctly.
2.
Check if there is any other possibility of being
any overcurrent to the MPPT
F34
AC Overcurrent fault
1. Check the backup load connected, make sure it
is in allowed power range.
F35
No AC grid
Please confirm grid is lost or not.
Check the grid connection is good or not.
Check the switch between inverter and grid is on or not.
F41
Parallel system stop
1. Check the hybrid inverter working status. If
there's 1 pcs hybrid inverter is in OFF status,
the other hybrid inverters may report F41
fault in parallel system.
F42
AC line low voltage
1.
Check the AC voltage is in the range of standard
voltage inspecification.
2.
Check whether grid AC cables are firmly and
correctlyconnected.
F47
AC over frequenc
Check the frequency is in the range of specification or not.
Check whether AC cables are firmly and correctly connected.
F48
AC lower frequency
1.
Check the frequency is in the range of specification or not.
2.
Check whether AC cables are firmly and correctly connected.
F56
DC busbar voltage
is too low
1.
Check whether battery voltage is too low.
2.
If the battery voltage is too low, using PV or grid to
charge thebattery.
F58
BMS communication fault
1.
it tells the communication between hybrid
inverter and batteryBMS disconnected
when"BMS_Err-Stop" is active.
2.
if
don’t
want to see this happen, you can
disable"BMS_Err-Stop" item on the LCD.
F59
AC Grid overcurrent
1.
Chech AC current.
2.
If there is no grid check the discharge battery current.
F63
ARC fault
1.
ARC fault detection is only for US market.
2.
Check PV module cable connection and clear the fault.
F64
Heat sink high
temperature
failure
1.
Check whether the work environment temperature is too
high.
2.
Turn off the inverter for 10mins and restart.
9.2
Battery errors
If the error appearing is related to batteries, please check the Battery Manual.
