I've just bought a Kipor 2000 and whilst it is quiet, as generators go, it is too loud to use around other campers.

1. I'm thinking a baffled box with some sound deadening material in it, to put at the exhaust end.

2. A decent length of some sort of metal braided hose that may absorb the noise if laid on the ground, or perhaps even dunked in a bucket of water (a la outboard motor silencing).

Some of you bright sparks must have solved this problem.

Help, please.

Jim.

My solution has been to simply be far enough away from other campers that it is not an issue. We like places away from others anyway.

Also when with a club group we tend to corral a campsite away from others where possible and then shre the power from one or two gennies during the day so nise is not an issue. We never run gennies after about 6pm.

Just gotta use that uncommon sense Jimbo!! How does using the Kipor compare to your previous Solar setup?

Steve,

Unfortunately some of our favourite spots get quite a crowd and I don't want to upset anyone.

The gennie worked a treat on the weekend. I hook it up to a 17 amp 3 stage charger and brings the battery up very quickly. Whislt I'm doing this I run the fridge off the 240 as well and crank it right up. I also baked loaves of vread in the breadmaker whilst I was doing this.

Very happy with it other than the noise.

Jim.

Yes, I suppose that closer to a bigger city there it would be hard to find a good spot that does not have 10 other people there!

Isnt this the genny you were sprouting about a while ago as the worlds best?

anyway back to camping.get there first, put the genny right out in plain site so nobody can complain, with a big sign I HAVE A GENERATOR AND USE IT...
people will move on then. Best of both worlds :D

Either that or leave it at home.

Hi Jim,

If you luck out with any more details on the sound deadening box that guy made I would be most appreciative if you wouldn't mind sharing the info as I am trying to come up with something similar at present.

Could you please email me at ryjoe@ozemail.com.au if you have any luck?

Thanks.

Baffled box is great Jimbo - I don't know whats used in that box , but you can buy heavy weight sound absorbing part lead sheets at Jaycar.

Also bike shops sell small sheet packs of stuff for re-doing muflers as they burn out over time.

You can however get a significant effect from a short piece of flexible metal pipe which goes over the exhaust end and just diverts sound down close to ground - sort used as a jerry can funnel - this causes the sound to have to be reflected from the ground and majority goes up.
Not as good as box but cost effective. We carry a couple of such devices to put over exhausts on our trail bikes when around others.

Before we bought the Honda, we looked a plans of silencer boxes from people on this and other forums. They all used an extractor fan of one type or another. The guy at the shop where we bought the genny said don't do it - using any sort of box would be too hot and would invalidate the warranty. As it is, some people have problems with the Honda overload tripping when running a caravan air conditioner in very hot weather.

I generally find that my wheel parked on top of a genny makes em pretty quiet :-) LOL

seriously its easy to make up a baffled box like stated, with fans etc powered by gennie, use a combo of reflection and absorbsion with accoustical foams and mass deadening.

I have the perfect solution for dill's like you.

and that is

buy a Honda 2.0i in the first place and you wouldn't have this agro, sleep deprivating problem that will cause Mrs Baz to do unspeakable thinks to you if you happen to fire up the said 'yellow peril' in her vicinity.

If you don't believe me just ask Rock Crawler, Pesty and Truckster as all three have been on the receiving end of her intimate robust and very descriptive prescriptive dialogue.
