Hi Todd,
Do you need three-phase? Depending on where you are, you may have a hard
time talking your PoCo into running three-phase to a private residence.
If
you have a lot of three-phase gear, might be
better to rent some old
industrial space or something ;) You also have the option of phase
converters and MG sets like the home machine shop folks but those can get
pricey.
Rotary converters are effective but pricy. Solid state variable frequency
motor controllers (basic ones) are a lot more economical. They will do for
a few kW of 3-phase power. They will also serve if you need a different
frequency ? not usually a consideration but it matters if you have an old
Cyber, or possibly some military surplus gear.
