I'm off grid, running my house and a small workshop in the basement. Using a 4.5kW PV array with storage in a forklift battery 24x2v cells. Island grid created by a Victron Multiplus 5000 inverter charger. This puts the energy into the battery pack and supplies house with the demand. Have a diesel generator for backup and when solar is low, such as from Nov to Feb. (In Inverness, Scotland). Rest of the year solar is sufficent. Wind turbine in basement waiting to be put up which will complement the solar.
If running planer/thick for more than just the odd pass, if not a good solar day, then I might run the genny while the machines are on, otherwise just run on sunlight. The victron gives very clean power, pure sine wave, better than grid! It also allows for power assist, where it will supply battery power in addition to genny power if high loads demanded.
Any questions ask away...
