The spray foam kits don't need any power. They come in pressurized containers(2 parts) with hoses, gun, and mixing nozzles.
If you were to go with the spray foam kits, keep in mind that the tanks have to be very warm for them to work properly. The directions on them will tell you the temp that the tanks need to be at for installation.
With a house that large, it could get rather expensive with the spray foam kit.
You might want to consider someone with a mobile unit come out and spray it, if you choose the spray foam.
With that size of house, I would go with the foam board(pink stuff) that you can get at any home building center. Cut the foam a little larger to make a nice tight fit between the studs. This comes in many different thicknesses, so you can choose the R-value that you want for the house, and cost that will fit your budget.
Good luck, and have fun with it.
