Error code
Description
Ongrid - Three Phase
F36
AC grid phase error
Hardly appear the code. Never ever happened so far.
F40
DC over current
Hardly appear the code. Never ever happened so far.
F39
AC over current(one cycle)
1. Check AC current sensor and its circuit.
2. Restart the inverter, if the fault still exists, contact your
installer or Deye service.
F41
AC Line W,U over voltage
Check the AC voltage protection setting. And Check if the AC
cable is too thin.Check the voltage difference between LCD and
meter.
F37
AC three-phase voltage unbalance
failure
Hardly appear the code. Never ever happened so far.
F38
AC three-phase current unbalance
failure
Hardly appear the code. Never ever happened so far.
F55
DC busbar voltage is too high
1. Check PV voltage and Ubus voltage and its detection circuit.
If the PV input voltage exceeds the limit, please reduce the
number of solar panels in series.
2. For Ubus voltage, please check the LCD display.
F43
AC Line V,W over voltage
Check the AC voltage protection setting.And Check if the AC
cable is too thin.Check the voltage difference between LCD and
meter.
F45
AC Line U,V over voltage
Check the AC voltage protection setting.And Check if the AC
cable is too thin.Check the voltage difference between LCD and
meter.
F42
AC Line W,U low voltage
Check the AC voltage protection setting. Check the voltage
difference between LCD and meter. Also need to check whether
AC cables are all firmly and correctly connected.
F44
AC Line V,W low voltage
Check the AC voltage protection setting. Check the voltage
difference between LCD and meter. Also need to check whether
AC cables are all firmly and correctly connected.
F46
AC Line U,V low voltage
Check the AC voltage protection setting.
F47
AC Over frequency
Check the frequency protection setting.
F48
AC lower frequency
Check the frequency protection setting.
F49
U phase grid current DC
component over current
