If they don't have the out put level you want they will tell you where you can get it. I know Duke power has installed units if that's what you're looking for.
They have a range of portable ones from about 1200-8000 watt generators. If you're looking for installed ones they go up to 22,000 watt
I doubt lowes will have that high wattage. Rental places have large mobile units. Herc, Sunbelt, United rentals, etc.
