CVGC works on 120V on my EU3000 just fine (though only at 45A output).Also as far as I know the new V2 Chargeverter cannot work on 120V.

No...All the noise from an internal combustion engine is "mechanical" and that’s what mufflers are built to suppress.
Cut the muffler off a car and you’ll definitely hear a difference.
Take that same muffler off a car and put it on that generator and find out if its as quiet as the car...All the noise from an internal combustion engine is "mechanical" and that’s what mufflers are built to suppress.

Run a generator off a car engine with a muffler and see if it makes it louder.Take that same muffler off a car and put it on that generator and find out if its as quiet as the car...
Not sure what you are suggesting here.Run a generator off a car engine with a muffler and see if it makes it louder.
A had a VW with an air cooled engine and it wasn’t very loud until the muffler fell off.No...
The exhaust noise from an air cooled motor is about 1/3 the noise of the setup.
Yes, you can silence the exhaust tone with a large well designed muffler, but you will drasticly reduce the horsepower of the motor if you do.
A large reflective design resonator can help though.
a lot of the sound is coming from the moving parts through the casing. If slapping a big muffler on would quiet them down to a level like a quiet fully enclosed inverter generator then we wouldn't be having this conversation.I've never tried one but there are add on mufflers for generators. They get decent reviews.
I'd recommend that if you try one you should mount it with vibration dampening pads and washers.
Some even incorporate extension pipes with through wall mounts.

Heh, thw vw putter sound is unmistakable... but that motor is in a faurly well insulated engine compartment...A had a VW with an air cooled engine and it wasn’t very loud until the muffler fell off.
Not every day - just as emergency backup. Part of this is I'm just annoyed at how bad noise mitigation turned out with shed! so I want to continue to experiment.That is kind of like my setup in case a SHTF type situation comes along.
I have two Honda EU-3000is and one Chargeverter along with another Meanwell charger that will put out 2500W.
I like having the redundancy in case one Charger dies or one Generator fails, but your case is different!
Based on your statements I assume this will be used every day?
If you still have the shed, pull off all the indoor drywall, have batts of rockwool installed tight, and mount the generator to the floor with rubber pads.Not every day - just as emergency backup.

I'm going to try the dual GenMax 4600 wtih parallel kit. I can compare this with my existing Champion and will report back eventually.
Thanks for the encouragement but the shed was a DISASTER. Overrun with exhaust (Co2 Monitor >200/beeping), too hot (>110F in summer) inside the shed, and what really did it was my DIY exhaust thimble caused a fire in the wall which reached 100lb propane bottles which cascaded to venting/blowtorching - horrible!. Not going to risk any of that again. From my point of view, just a bad, bad, bad design/experience all for a modest reduction in terms of noise abatement.If you still have the shed, pull off all the indoor drywall, have batts of rockwool installed tight, and mount the generator to the floor with rubber pads.
Use a metal thimble to safely vent the exhaust.
we have some of those out here at work ... yeah -- going to be allot more noise than he is looking for ....sounds like a huge lawnmower runningHow about the DuroMax 9000 inverter generator.
Please do!Could I use that disclaimer on my post?
Rebuild with concrete blocks, fill all the cavities with concrete. Then figure out the roof and door insulationThanks for the encouragement but as I said at the beginning - the shed was a DISASTER. Overrun with exhaust (Co2 Monitor >200/beeping), too hot. and exahust thimble caused a fire greatly enhanced once it reached the 100lb propane bottles which caused venting/blowtorch affect. Not going to risk that approach again - just a bad, bad, bad design/experience all for nothing in terms of noise abatement.

Yes sir - Thinking about a cannot-possibly-burn shed enclosure *outside* in the front of the shed. I have been thinking Unistrut framework and left over metal roofing and rockwool but I could also do concrete block retaining wall 'walls' - just stack some blocks and maybe attach some rockwool. I'm thinking about focusing on directing sound away from the west and south (neighbors) toward the north (100ft to street) and east (60ft to our house).Rebuild with concrete blocks, fill all the cavities with concrete.

If I could get it down to <60dbA at the property line (instead of my previous 70dBA) this would be approaching success in my mind.
First up - I'm going to compare 2 x paralleled smaller / quieter units based on @robby comments instead of going with another 8000-10,000w unit and compare with the 8000w Champion and establish some data.
That would be cool.I think i could build a shed to get the generator noise below 50db
...
I have a lot of generators, i will make some plans up, and build something this fall...
Exactly.On thing to keep in mind on these 6kw and larger generators were running is a LARGE part of the noise and I mean a LARRRRRGE part of the noise is not coming out the exhaust pipe like on a car. Its coming from the motor casing ITSELF. No muffler is going to silence one of these completely.
Whatever you use for an enclosure is going to make the biggest difference for serious noise reduction.
The old iron block generators didn't have these problems. My friend has a 20kw water cooled generac and even with the muffler removed from it the thing sounds like a honda compared to my 12kw pulsar generator.
