Because the voltage of the drive motor of the inverter contains abundant high-frequency components.The voltage waveform of the inverter-driven motor is not a sine-wave voltage, but a pulse-width modulation (PWM) voltage.

The application of solar energy is more and more widespread, effective energy saving, and power supply in places where electricity cannot reach, bringing great convenience to irrigation

If the frequency converter has over temperature fault, the corresponding processing methods are
