    5 tips for using 1-phase 220V to 3-phase 380V VFD

    1. The power at the input of the variable frequency drive must be sufficient, otherwise the operation will jump under voltage fault can not be normal operation.
    2. Single phase 220v to three phase 380v VFD belongs to the boost circuit step-up, for the load side of the maximum for the light-load site below 30hp (22kW), in terms of selection, the light-load motor use a large level of VFD, heavy-load site use a large two-level VFD.
    3. 1-phase to 3-phase VFD can only be used for motor class inductive load, can not be used as other load power supply.
    4. The VFD is not suitable for the need to quickly start and stop the site, and the occasion of the bit energy load.
    5. Part of the equipment motor can be used by changing the motor connection three-phase 220V electricity (such as motor star connection state is three-phase 380V motor, can be changed to delta connection can use three-phase 220V, the specific can consult the motor manufacturer), at this time can buy ATO single-phase 220V to three-phase 220V VFD to solve the problem of phase change.

    This video is about how to use buttons to run single-phase VFD of three-phase motors.

    The video shows the parameter setting methods for the V/F control mode and vector control mode of single-phase to three-phase VFD.

    This video provides insights into the wiring process for converting single-phase to three-phase VFD, specifically from 220V to 380V.

    Existing reviews of 3 hp VFD, 1-Phase 220V to 3-Phase 380V VFD
    VFD related information
    Please, I bought an ATO VFD to reduce the speed of my electric motor to 1800rpm from 3450 rpm.
    The manual that came with it says solar inverter. I tried to follow the steps in setting it up and I could get it to work.
    Please, I would appreciate it if someone could create the time to take me through setting up this VFD / electric motor project.
    Find attached photos showing the VFD and my electric motor.

    Sorry to have bothered you.
    This model of VFD is customized by solar inverter. It can achieve single-phase 120V input and three-phase 220V output.
    About using, VFD red line and green line connection input 120V. U, V, W connect to the power line of your three-phase motor, parameter setting please note that FE-00=0, (PV function is turned off), you can refer to the attached document for a quick setting guide.
    The best 3hp VFD
    To run a 3hp 3ph motor of single phase do you need a 3 hp vfd or one that is overrated?

    ATO Responded
    It based on motor rated current. Please send us your motor rated voltage and current. And what is your available supply voltage (VFD input)? So can recommend you the most suited drive.
