3000W Chinese Gensets Info.

Where you been? Good to see a post from you. We have recently mentioned spark arrestors (screens). Did you try the muffler/screen S3 and did it lower the db by 3/5? I know for sure the screen on my Champion does lower the noise level when inserted by some amount. Now I'm beginning to understand ? the story of some that post not being able to start a A/C with underpowered Inverters.
So there is a advantage of using these old clunky heavy flywheel gensets. Reading these different threads is like taking a 101 class in Power Generation. I miss MrWizard giving his take. He once gave his idea that the AVR suffers and possibly fails from the spikes. Mostly due to a shut down with a load. Me thinks the AVR has a weak sister somewhere in a component, I understand even most Capacitors are rated from a mfg for only so many starts, like maybe 2000 on a compressor. So interesting when posters pass along what they have discovered. Now, will you kindly give more info' on the surge protector you reference. The only concern for me is over voltage. From what we are learning, the possibility of this happening from our portable genny is low. But, better to be safe than sorry. I do believe Prof95 will soon lead us in the right direction. My gut feeling is, he is deep into the project.

I got the S5 with resonator and yes it lowered the db level by at least that much maybe more. I have not had a chance to chenck it in depth yet.

I am currently building an enclosure that has made a huge difference so far but am not ready to post the pics or results yet. I will say that I have quieted it down by 15 db so far. I started at about 87 db and am down to 72 db at 10 ft. My yard is pretty small so I am limited by that to the distance I can measure.

Outside of my yard I can hardly hear it since there is a block wall. I have one neighbor that can hear it pretty well due to the design of our houses and the way they sit so I still need more work.

In their back yard noise level is at about 65 db. They can carry on a normal conversation but it is annoying after awhile. I don't want them to listen to it for long. The generator is within 7 ft of my block wall and it seems to reflect into their yard.

I read this and other threads almost always once a day or more.

EDIT:

Powermate closed down production for good? That may be why I got my 5700 continuous generator for $400. Not good news for me but I still got a great deal on the gen.
