a/c rods are sold just about any where,and for the common man a/c will do fine,as for generator purposes.. most small miller,hobart,lincoln's are rated at 10-12000 watts on the generator side which will run a small place,but be sure of your consumption/amps needs,onee other sugestion would be to look for r/v gen sets, i have a onan 6.5 that i'm rigging up, for a JIC.
