Just bought a 5.5kw VFD from ECOGOO. 220 to 380v version. 5.5kw giving me a bit of headroom for 3.9kw motors.

Will see what I get charged for vat and duty etc. £185 so far.

I'll bypass all the brake and startup contactors, mount the VFD on the machine with a remote start stop switch on magnets so I can put it where ever I am working.
