Can I get by without having to buy an inverter stye gen. set. I know they are louder but cheaper.
Yes, you can get by with cheaper one. BUT, (JMO

My 2800i Is a bit louder than some, but not offensively loud at all. I face it away from others and mainly only run it to re-charge the Batts. (2 6v Batts and a 3000w, 12v inverter for routin 120v needs)
