Single phase induction motor has specific wiring requirements in connecting with GoHz single phase VFD, to enable your single phase motor running properly, please follow below instructions step by step:
Wiring instruction of removing motor capacitor
Remove capacitor of the single phase motor, connect the common terminal Z2/U2 (single phase motor has two windings) to the VFD's V phase, connect the other two windings U1/V1 & Z1 to the U & W phase of the VFD output terminals.
Power on the VFD, set P9-13=0, run the VFD and observe the current. If the current is too high, stop the VFD, set P0-15=10, P1-02=160, and run again. If the current still too high, stop the VFD and switch the motor connection of U & W phase.

Wiring instruction of keeping motor capacitor
Connect single phase motor input lines (L, N) to the VFD's (V, U).
Power on the VFD, set P9-13=0, run the VFD and observe the current. If the current is too high, stop the VFD, set P0-15=10, P1-02=160, and run again. If the current still too high, stop the VFD and switch the VFD's U phase to W phase.

Setting up the VFD was straightforward, thanks to the keypad control and the ability to easily adjust the frequency using the digital settings. I also appreciate the built-in PID control, which helps keep everything in sync and makes my process management smoother.

Inconsistent Performance and Overheating Issues
While it claims to support both L-N-G motors and split-phase, I found the performance to be inconsistent, especially at lower speeds. The VFD tends to overheat despite the fan, which isn’t ideal for extended usage.

Very comfortable with the price
I am very comfortable with the price of this 2 hp inverter, which provides very powerful output capability and flexible speed control, and especially excels in machining and mechanical equipment.

Yes, our VFD infeed can be received as L1, L2 (Not L1, N), and Split phase 240VAC , just connect L1, L2, To drive 2 lines which is correct.

My infeed is L1, L2 (Not L1, N). Split phase 240VAC, can it be used with your 1-phase drive?

Versatile Performance and Quiet Operation
One of the standout features of this VFD is its versatility. It allows me to easily adjust the motor speed according to my needs, which has significantly improved the efficiency of my equipment. The build quality is solid, and it operates quietly without any noticeable vibrations or noise.

Ok, that is fine, just for this bowl feeder (which is composed by 3 coils that electromagnetically produced vibrations into mechanical vibrations), it pulls high inrush/surge current, so we recommend using 10kVA Converter, Not 5kVA one.
Based on your specs, recommended frequency converter model: HZ-50-1110, 10kVA power capacity, input: 1ph, 120V (+/- 10%), 50/60Hz and output: 1ph (L,N,G), adjustable (0-300V), adjustable (40-120Hz).

We would likle To convert 1-phase, 120V, 60Hz supply To 1-phase, 220V, 50Hz To run a bowl feeder. The peak current is 5.2A. The bowl feeder is composed by 3 coils that electromagnetically produced vibrations into mechanical vibrations. What do you recommend to use, please?
