That said, why not try one, set it down 110V and use a dummy load and measure what it outputs.
VFDs vary voltage according to frequency, so at below motor rated speed, they're reducing voltage anyway, it's just that I'm not sure it'll be as simple as changing a single parameter.
If I had a standard VFD surplus, I would try it and see, but I've not just now.
