The first problem is that many gensets have a limited run life, they are designed for emergency backup not regular use. The second problem is that a lot of machinery from China is junk--gensets included. Some run loud, some hot, many with small fuel tanks will also run so hot in normal use that you CANNOT refuel them until they've cooled down.
I'd rather buy a cheap parachute than a cheap Chinese genset--or anything else with moving parts.
Then there are exhaust and monoxide problems as well. Great backup for occassional use--not so great for regular use.
I'd look around for a 90-100 amp rated genset (that's all you can run on one v-belt anyway) or look for one wind charger.
