Running 3 phase VFD with single phase 220

I have to run a 3 phase 230V VFD but I only have single phase available, any suggestions would be greatly appreciated.

I'm doing the same with a Teco VFD (JNEV-101-H1 I believe). It's running a 3,600 RPM / 1.5 HP motor, and so far it has performed flawlessly. I have wired external controls for fwd/stp/rvs as well as a potentiometer. Been running this setup for a little over a year and use it nearly every day. If you go this route, make sure to put it in a safe location, preferably in an IP65 or higher rated job box. The drive itself is Nema1 rated best I can remember. I bought the motor/drive as a package from DealersElectric.com for around $200 delivered. As you can see in the picture, it's running the 3phase/230v motor from a 115v outlet. I have a 20A breaker on this outlet.

Personally, I don't care for that type/variety of VFD..... they generally have lots of problems and issue over time.

I can't speak directly to that particular VFD, but do know that the KBAC controllers require a single phase 110 or 220 input, depending on the VFD model/motor size. I also can tell you that with the KBAC VFDs, 1.5hp is the max you can run on 110/115V.
