10.1 ERROR CODE
If there is any failure,the LCD screen will display an alarm message. In this case,the inverter may stop feeding energy into
the grid. The alarm description and their corresponding alarm messages are listed Table 10.1.
Error code Description Ongrid - Three Phase
F01 DC input polarity reverse fault Check the PV input polarity.
F03 DC leakage current fault Hardly appear the code. Never ever happened so far.
F07 GFDI blown fuse Hardly appear the code. Never ever happened so far.
F11 AC main contactor errors Hardly appear the code. Never ever happened so far.
F12 AC auxiliary contactor errors Hardly appear the code. Never ever happened so far.
&ϭϰ
DC firmware over current Hardly appear the code. Never ever happened so far.
F08 GFDI grounding touch failure Hardly appear the code. Never ever happened so far.
F02
DC insulation impedance
permanent fault
Check the grounding cable of inverter.
F04
Ground fault GFDI Check the solar panel output connection.
&ϭϳ
Hardly appear the code. Never ever happened so far.
F09
IGBT damaged by excessive drop
voltage
Hardly appear the code. Never ever happened so far.
F10
Auxiliary switch power supply
failure
F05 Read the memory error
Failure in reading memory (EEPROM). Restart the inverter if the
fault still exists, contact your installer or Deye service.
F06 Write the memory error
Failure in writing memory (EEPROM). Restart the inverter if the
fault still exists, contact your installer or Deye service.
1. It tells the DC 12V is not existed.
2. Restart the inverter, if the fault still exists, please contact
your installer.
&ϭϯ
Working mode changed/Grid
mode changed
1. Lost of one phase or AC voltage detection circuit or relays not
closed (old inverter not have relays detection function).
2. Restart the inverter, if the error still exists, please contact your
installer or Deye service.
&ϭϱ
AC firmware over current
1. The internal AC sensor or detection circuit on control board
or connection wire may loose.
2. Restart the inverter, if the error still exists, please contact
your installer or Deye service.
&ϭϴ
AC over current fault of hardware
1. Check AC sensor or detection circuit on control board or
connection wire.
2. Restart the inverter or factory reset, if the error still exists,
please contact your installer or Deye service.
&ϭϲ
GFCI(RCD) Ac leakage current
fault
1. This fault means the average leakage current is over 300mA.
Check whether DC power supply or solar panels is ok, then
check 'Test data'-> 'diL'value is about 40; Then check the
leakage current sensor or circuit (the following picture).
Checking test data needs using big LCD.
2. Restart the inverter, if the error still exists, please contact your
installer or Deye service.
Three phase current,
over-current fault
