[115] Voltage too high of DC bus line
Check if voltage of power supply is
normal
Check if wire of electric box is correct
Measure if DC bus line voltage
between P and N of module is
over 644V
Circuit of DC bus line voltage
on inverter control board
abnormal, replace inverter
control board
Improve power supply circuit
Correct the wiring due to
diagram
Check rectifier, reactor,
electrolytic capacitor in
inverter main circuit
