hi graham
i had the same issue with three phase. the company wanted over 12 grand to supply me.
so i went to DrivesDirect and got great service and a reasonable price. i think i paid under £3k.
but unlike small inverters which are “one per machine” this one supplied the entire workshop.
and the xyz is basically a 110v machine so all the controls, the cnc servos work from a 13amp plug top.
