I thought about a knock off brand generator but I decided to spend a little more and get something of quality. I recently bought an 8000 watt NorthStar generator with a real Honda engine and it uses a brushless generator head. I hook that up to a 6 circuit transfer switch. Works great. Runs 90% of my first floor lights, outlets, fridge, and TV's. It will not run the stove or our heat/ac pumps. It will run some space heaters and we have a propane fireplace.
This unit puts out so called clean power, so my smart TV's and computer work fine. I have $1900 into the generator and transfer switch from Lowes. This is for my house here in NC. I just made sure we'll never lose power again

I think it's cheaper in the long run to buy a better unit to begin with.
