If you need auxilary power for your home or business to keep the freezers or furnaces or the milking machine in the barn going, buy a cheap, loud generator.
I have 3 generators and each has it's place.
My 45,000 watt Katolight will run everything on the farm. It's powered by a 90 hp John Deere tractor.
My 6,500 watt Coleman/Honda 13 hp I bought because it was cheap. I can't use it around people because it is to loud. I would guess a Generac is comparable db.
My EU3000 Honda is the one to buy. Spend a little extra and go with it. Buy 2 if need to. They hold their value.
Remember, every 10 db is double the noise.60db is twice as loud as 50; 70 db is 4X as loud as 50 db, etc.
Good Luck! Roger
