Off grid shop,if I did it,I would use a diesil motor,something cheap and long lived like a Perkins 3cyl tractor engine.
I would have a alternator(10,000 watt)for lights and small tools only and use hydraulic pumps and motors to run the big tools.
I had it figured once to plumb the shop with 1-1/4" black iron pipe,1 pressure,1 return for the mains and reduce down to 1/2 or 3/4 for the branches,run the system at 900-1000 psi and about 30gpm.
Hydrualic motors can be had for $100 -125 these days and many of those can deliver hp in the 5-7-1/2 range.
Plus you also have foward/reverse and variable speed with the right valving.
