Thank you so much for the help John. I have contacted HOLIP in China and they were unfortunatley not exactly helpful, they just reiterated that the HLP-SH110 is a 3 phase only unit and nothing more. You're correct this doesn't sound like DIY electrical plus there is also the issue of not being able to obtain any of the settings in fregard to the VFD set up due to the original supplier no longer existing.

Ideally a plug and play solution would be best and that is what I thought the Digital converter would do, as in power the VFD but now it all sounds like an expensive risk.
