RE: 3000W Chinese Gensets Info.
Hey Professor! Any plans for carving up the dashboard? It looks really basic 18 wheel. What kind of goodies can you stuff in there?

RE: 3000W Chinese Gensets Info.
Question for Professor 95......
.........I have a crackerbox welder(225AmpAC\170Amp DC) that I'D like too power from a Chonda genset ; My question : what KW size of generator would I need to purchase too Power a crackerbox welder ? I was thinking 10kw , but an electrician friend said 10kw won't be big enough ! So , can you do a little mathematics and calculate the size giny I'd need to accomplish this ? , thanks , jf
Although I am not Randy (professor95), I feel I can answer your question somewhat.
I have tried to run a "crackerbox" 225 Lincoln with several size generators. What I have found is that a 6KW will run the welder, but not correctly. The arc seems weak and the penetration is less. Turning the amp knob to a higher setting has no effect. The same results happened with a 10KW generator, but to a lesser extent.
A 14KW generator ran the welder perfectly, I could tell no difference between it and grid power as far as laying the bead goes.
I suspect this has to do with the fact that welder transformers are known to have an extremely low power factor rating.
Makes me wonder if a 10KW gen will power the welder if a bank of hard start caps are installed. It sure makes my 3500 genny breath easier when my coach A/C starts up. One would think that the initial strike of the arc would be the same type power draw as a compressor rotor.

WoW! I posted this on June 13th of this year. Talk about digging in the archives! LOL!!!
I wondered where it came from. It was in the posting from Old & Slow on 11-10-09. I made the mistake of "assuming" it was very recent.
Guess Floyd has a good reason to use the screen name "Old & Slow" :)
Floyd is a good guy. No biggie!

RE: 3000W Chinese Gensets Info.
I gotta agree on running propane in a genset that is not designed for that fuel. I know several RV and aircraft guys who have done conversions and the exhaust really stings to high heaven. Almost a rotten egg smell Must be the corbon monoxide or other pollutants that are not good for your health. Far from the exhause generated from a properly made propane engine such as on a forklift.
I have been running two generators on propane for over four years. They were not initially designed for propane. Never a smell from the exhaust as you describe. IMHO, it is a perfect fuel. No storage problems, no gum, no water, no trash. Just clean ready to go fuel. Power from the generators appears to be equal to gasoline fueled.
Safe? What would be more dangerous in the system than gasoline and a leaky fuel bowl needle and seat? LPG is basically a closed system with no fumes. With the electric fuel line solenoid and vacuum actuated zero pressure regulator leakage of LPG is less of a risk than in a gasoline system.
The only down side is having to use multiple Bar-B-Q tanks for an extended camping stay.
At home the 300 gallon in-ground LPG tank connected to the Champion 13 HP engine negates having to refuel the gas tank for an extended power outage.
BTW - engine oil is exceptionally clean at recommended oil change intervals, not black like with gasoline. I have not sent any oil off for testing, but I strongly suspect changing oil at 50 hours is not needed with LPG.
Remember, I own and use two LPG fueled generators. This is first hand experience, not what somebody else has told me.

RE: 3000W Chinese Gensets Info.
Sorry to say but if this guy wants to take the chance of injury to himself or family, that's his business.
He is the one who WILL pay the price.
Pressurizing the fuel in a chinese genset is crazy. When something goes wrong in the middle of the night and the family is in the coach,.....................Someone is going to die!
Don't be stupid dude!!!!

Concerning the useable wattage of the 3500 watt sets that are out there now, I gotta agree that the best you will get is 2400 to 2800 useable watts of power. Remember that 2400 watts is a solid 20
amp circuit at 120 volts. Usually enough to run the A/C in a coach or trailer along with running a few other items to make you comfortable.
Right now my genset is sitting in a hanger because I purchased an old Cessna 172. No power in the hanger. It's enough to run a few lights and power tools while I work on the aircraft. That little 100 pounder with the Honda knock-off sure comes in handy! The aircraft flies very well and is certified for flight. I'm just working on the cosmetics as in buffing out the paint and cleaning up the interior. Not much I can do not being a certified aircraft mechanic. But I can get her looking as good as she flies. :)
Don't worry, I still own the Jayco 2300 and love it! Still running great after 30 years but she is getting really long in the tooth on the interior. Lots of great family time inside that coach!
Long time since I have been here! Still looks the same.
