Champion 5500 Watt (6750 surge) 11 HP generator...got this on Craigslist for $150...nice thing about it is that it has a 25amp/3000 watt 110v RV plug, Total 110/220V amp ratting is 40/30 amps, so I could also run a second cord and run up to another 15 amps on 110....only problem is it is loud at 74 db.
Has anyone actually used a Plastic Pet Dog-House for a Generator Cover for soundproofing? I have a 31" wide x 37" long by 31" tall Petnation Dog House my pup does not use or like...picked it up on Craigslist for $15 (Last time I looked there were at least a dozen on there for sale!)...for the heck of it I took off the wheels on my Champion Generator and sat the generator down inside the bottom of the house (house like these easily split into) Pulled the starter cord and then installed the top portion of the doghouse and it cut the noise in half and with out any noise insulation/sound proofing...had the exhaust pointing out the doggy entry side
I did try placing a stock Harley Davidson XL1200 stock muffler over the exhaust port but it really didn't make that much difference...(it's got a pretty quiet muffler) just slight reduction in noise. Most of the noise is coming from the intake air side where the pull cord is!!!
I figure if I install some insulation and redirect the exhaust out a bit further with a pipe and install some ducting on the output of the generator cooling duct to the front as well (to keep any of this intermixing with the cool intake) it should run cool and quiet with out spending a ton of money on this project...nice thing about the dog house is as I said it splits into at the middle and you can place the top side inside the bottom half...and this can sit over the top of the generator in the back of my pickup!
If you have a smaller generator you could use a Med size dog house.
Any other suggestions are welcome!
