Error code
Description
Ongrid - Single Phase
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
.
F14
DC firmware over current
Hardly appear the code. Never ever happened so far.
F17
Hardly appear the code. Never ever happened so far.
F10
Auxiliary switch power supply
failure
Hardly appear the code. Never ever happened so far.
F13
Working mode changed/Grid
mode changed
Hardly appear the code. Never ever happened so far.
F20
DC over current fault of the
hardware
Not avaiable.
F15
AC firmware over current
1. The internal AC sensor or detec�on circuit on control board
or connec�on wire may loose.
2. Restart the inverter, if the error s�ll exists, please contact
your installer or Deye service.
F18
AC over current fault of hardware
1. Check AC sensor or detec�on circuit on control board or
connec�on wire.
2. Restart the inverter or factory reset, if the error s�ll exists,
please contact your installer or Deye service.
F16
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 120; 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 s�ll exists, please contact your
installer or Deye service.
Three phase current,
over-current fault
F22
Contact your installer for help.
Crash stop (if there is a stop
bu�on)
F19
1. When inverter is running, wifi plug plugin,will occur F19.
2. Restart the inverter or factory reset, if the error s�ll exists,
please contact your installer or Deye service.
All hardware failure synthesis
F21
Hardly appear the code. Never ever happened so far.
DC leakage flow fault
F25
DC feedback fault
Hardly appear the code. Never ever happened so far
.
F26
The DC busbar is unbalanced
Hardly appear the code. Never ever happened so far.
F23
AC leakage current is transient
over current
1. This fault means the leakage current is above 30mA suddenly.
Check whether DC power supply or solar panels is ok, then
check 'Test data'-> 'diL'value is about 120; Then check the
leakage current sensor or circuit. Check test data needs
using big LCD.
2.
Restart the inverter, if the fault s�ll exists, contact your installer
or Deye service.
F24
DC insula�on impedance failure
1. Check Vpe resistance on main board or detec�on on control
board. Check PV panels is OK. Many �mes this issue is the PV
problem.
2. Check whether the PV panel (aluminum frame) is grounded
well and inverter is grounded well. Open the cover of inverter
and then check the inside ground cable is fixed well on the shell.
3. Check if the AC/DC cable, terminal block are shorted to ground
or the insula�on is damaged.
4.
Restart the inverter, if the fault s�ll exists, contact your installer
or Deye service.
