battery voltage. Then 52fault will occur
9 53 fault
Fig.7 53fault
Testing method:
Just connect the inverter to battery system, Switch on the inverter, if 53fault still occurs, it means DC-AC
circuit has the trouble. When AC output voltage reaches less than 230V and lasts for 20s. It will have the
error.
Solution:
For usual client, suggest replacing mainboard
For professional client, suggest deliverying some IGBT or Optocouplers to them and try to repair it.
M alfunction Reason:
Most of time, it is caused by DC-AC circuit, including IGBT, Driving circuit etc.
Repairing Method:
a. please kindly turn to diode position on multimeter.
