Table10.1 Error codes and their solu�ons
Error code
Description
Ongrid - Single Phase
F55
DC busbar voltage is too high
1. Check PV voltage and Ubus voltage and its detec�on 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.
F64
IGBT heat sink high temperature
1. Check temperature sensor. Check if firmware is suitable for
the hardware. Check if the inverter is its right model.
2. Restart the inverter, if the fault s�ll exists, contact your
installer or Deye service.
F56
DC busbar voltage is too low
1. It tells the PV input voltage is low and it always happens in the
early morning.
2. Check PV voltage and Ubus voltage. When inverter is running,
then showing F56, maybe Loss of driver or need update
firmware.
3. Restart the inverter, if the fault s�ll exists, contact your
installer or Deye service.
F57
AC reverse irriga�on
AC reverse irriga�on.
F58
AC grid U over current
Hardly appear the code. Never ever happened so far.
F59
AC grid V over current
Hardly appear the code. Never ever happened so far.
F60
AC grid W over current
Hardly appear the code. Never ever happened so far.
F61
Reactor A phase over current
Hardly appear the code. Never ever happened so far.
F62
ARC fault
Reactor B phase over current
Hardly appear the code. Never ever happened so far.
1. Check PV module cable connec�on and clear the fault;
2. Seek help from us, if can not go back to normal state.
