Any VFD gurus' out there?

Overboard?, perhaps. I was perhaps a little concerned with starting two large-ish motors in parallel off a single VFD - gonna be a chunk of amps there. But overspending the VFD may well help a bunch there. The motor plates add up to about 1.5HP which is around 1100W, so a 2.2kW VFD is not stupidly large.

I totally agree a larger vfd as an easier life if it’s only running at say 30to50% max capacity. And let’s face it the Chinese do dream about on there specs
I would arrange it so that both motors are not started at the same time as on start up the amps draw is a lot more than when in run mode
Maybe 2 or 3 seconds before motor 2 is started
