These are hardly over-the-counter inverters.
I would love to see you lift a 700kg panel loaded with custom bullt
circuitry and transfromers up to a counter. These are all custom built to
order units.
Again:
Show us one.

In a VFD or Variable Frequency Drive the AC is rectified to DC, then
inverted back to three phases of variable frequency AC to control the
speed of electric motors.

Just take a Trip the southern end of the Bonneville Power DC Powerline
that runs from The Dalles Oregon, to somewhere in California. the one
there is a lot bigger than 200,000 watts....

The ABB 200KW VFDs are small enough to hang on the wall. Don't take a
Trip to see them, ABB just had a shooting.

Geeeshh. Consult your own information links and read the literature.
I want to see you even lift a 200HP inverter used in the the panel.

Now you are just a sore loser.
But since you asked, this is what I have at home to lift and position
moderately heavy stuff:

It -should- be obvious that the wheels are normally on the ground.
They are much larger than the original wheels, for use off pavement. I
use it to line up structural steel to weld it, and to work on engines
at a convenient standing height.
A better view of a similar model:

With it one man can mount heavy stuff on the wall, like I did when I
was an industrial electrician.
This shop crane lifts up to a ton:

The tongue jack I welded on and the extra wheels on the far end are to
tow it around with the tractor whose tires are visible.
A 2000 Lb trolley on my sawmill log storage shed:

A larger, less portable version of this can pick up 3 tons, for
example pull out stumps. This one lifts 1500 Lbs.

Satisfied?
