Re: 3000W Chinese Gensets Info.
I looked around for a while trying to find the electric heads for my brothers Wen, and my PowerWise. Never did find anything reasonably priced to make it worth while. Let me know if you find anything. Teamjd wrote: I have been happily reading along here for years enjoying my WEN Pro 3500 Watt generator. The generator head finally gave up the ghost and started spitting out plastic pieces and died Sunday night (midnight of course) froze my but off the rest of the night. I was using it to power an electric heater in the pop-up. Is it worth replacing the generator head? Or keep the unit for spare parts and get another one. I am quite capable of doing the repair. The unit only has 250-300 hours on it in 6 years of use. Not complaining about the longevity, just if it's worth repairing.438Views0likes0CommentsRe: 3000W Chinese Gensets Info.

While higher power is available, it cannot be depended upon for sustained output in high temperatures without increasing the probability of AVR or other component failure. Just to add a little tuba to the prof's trumpet. (at least in the earlier 3000+ w listed ratings) I have 2 dead gen's in my garage, One is the 'PowerWise3500' purchased back on page 1 of this thread. The stator has a sticker on it "2.8kw 60hz 120v" I also have my brothers "Wen" brand 3500w. The stator on that one is ingraved with a bunch of numbers to include something like: 28kw120v240v60hz (followed by a few more numbers) For the record, both are dead with bad rotors. One has an open winding, the other has a winding shorted to ground somewhere. I was going to hand rewind them just for fun, until I counted turns and measured and realized it was going to be at least $50 for a roll of copper wire to do it.353Views0likes0CommentsRe: 3000W Chinese Gensets Info.
Test conditions: My back yard. 23' measured distance. Ambient noise <50 dba (lowest meter went). Radio shack digital db meter. Meter mounted level on tripod about 5' high, facing generators. Dead grass yard (snow just melted last week). I took the lowest 'steady' reading since birds were chirping, dogs were barking and kids were yelling in the neighborhood. All 4 sides were measured. Using the honda as example, standing over it looking down, side A 0deg was the elect panel, B 90deg would be right side were recoil handle comes out, etc. All were measured with this rotation (A side was recoil side of crankshaft). The etq800 has had the panels removed and a couple cans of undercoating applied to the inside of the case which droped by a couple db on my last test. The AllPower also has undercoat inside, and still has a plastic case rattle on top. So would prob be a little quieter if I can get rid of the rattle. FME, champ, honda, etq1800 are all stock out of the box. The FME is the one that's also sold under Magna, Lifan, Ramsond, Powerhouse. (Fully enclosed, electric/remote start.) *EDIT* Just some more notes. -I was tempted to add the Champ 2k inv to the test, found one at pawn shop for $449, but as it stands now, I have 3 gensets to sell, didn't want to make that 4 lol -the 500w load was a single halogen lamp that measured about 525w on house outlet -etq800 not tested at 500w load because it would trip overload from the inrush surge -the LOW labeling, is ECON mode ON, or low rpm. High would be with that ECO off, high rpm -you can see the etq1800 and FME 3300 were pretty close in results, but the 3.3kwh 'sounds' much better.. lower rpm deep tone. The etq had a 'tinny' sound to the exh note. On a similar note, the etq800 has low numbers, but is much more 'annoying' because of the tone and rpm. -the (fact spec) column is the db numbers I found listed on the boxes or factory webpage. And yes, I did find 3 different numbers on the etq website. For the record, I'll probably be keeping the FME 3.3kw for use with the trailer AC, and anytime lugging the large gen around isn't an issue. And I'll keep the etq1800 for when I need something smaller with no need to run AC. It think I'm going to do the undercoating on the inside of the etq shell since it worked good on the smaller one. I might try some of the sticky mat instead though, like is used in auto sound systems.309Views0likes0CommentsRe: 3000W Chinese Gensets Info.
A little off the recent topics, but still belongs in this thread I do belive. I seem to have aquired some more gensets (all inverters), either buying myself or borrow (the honda) for some sound testing. Still too much snow in back yard to do test in open like I want, will do that soon I hope, and will post results. For now, tested each gen with eco mode on (low rpm), no load, at about 21'. Had buildings on either side of where the db meter was located, so I'm sure I got some reflection and higher results than will be normal in open field. Just tested on one side (the side where the elec panel is on the honda) Honda 2000i 54db ETQ in1800i 58db ETQ in800i 57db FME 3.3kw 60db AllPower 2kw 63db The champ open frame is still snowed in, so when I get the full test done, I'll post results.211Views0likes0CommentsRe: 3000W Chinese Gensets Info.
I planned on leaving the new AP2kw alone till I could do some more db tests, but the rattle got the best of me and I tore it apart and picked up a couple cans of ruberized undercoating. Here's a peak inside. http://flic.kr/p/9nP5CE http://flic.kr/p/9nP61u316Views0likes0CommentsRe: 3000W Chinese Gensets Info.
Did some more testing tonight Dan. -The AC outlet appears to be a standard style duplex (both outlets in paral) -I loaded down the AllPower with a ceramic heater, couple halogen lamps, and another 100w light. Measured voltage/hz/wt via KillAWatt -With a 400-500w load it actually sounds like it's running lower rpm's than with no load. -around 1600w didn't seem to be a problem, altho I didn't leave it run very long at that, it is 20deg or so here yet. -I turned everything on, at about 1800w my KillAWatt started flashing, but gen kept producing AC and no overload led. (on a side note, the ceramic heater didn't act like a instant 1500w resistive load I thought it would, it would start at lower wattage like 900 then kept increasing) So with everything I had plugged in, turned on, I watched the wattage increase with the heater on. At around 1900w the Red over load led would light, and right around 2kw it would shut down the output. After about 5 seconds, it reset itself and everything would power back up. Noise level def louder than the little ETQ800. Most of the noise from the AP is from the plastic case and gets really bad at certian RPM's. Seems the worst area is right around the gas tank neck, the case might be hitting here so I may open up that hole a bit. Otherwise the noise seems to be coming from the seam of the 2 case sides.418Views0likes0CommentsRe: 3000W Chinese Gensets Info.
Just a small update: Put the AP 2k inv back together last night after cleaning up the valdez slick. My prior ETQ tests were in the open in the back yard, with gen sitting on grass. with a low of 58db. Last night with the ETQ on concrete and snowbanks around the driveway, I saw 63-64db. The AllPower was 67-68db under the same conditions and same side (panel opis of exh) I was still hearing a loud plastic rattle, seems to be coming from fuel filler neck to case junction. I was out in the cold alone so didn't have anyone to stop the rattle while I steped away and read the db meter. If I have some time this weekend I'll try some more tests, maybe with bigger load, and also check the output with the kill-a-watt and on the o-scope.406Views0likes0CommentsRe: 3000W Chinese Gensets Info.
Well I cleaned up the oil mess a bit, filled with oil and gas and gave it a try. Took a dozen or two pulls before it fired up (unlike my champion, etq, and powerwise that all started the first time with 2 or 3 pulls). Pushed the choke back in and it settled into a pretty low idle. I plugged in a 500 light, the rpm surged up for second and then idled back down again to what seemed close to the no load rpm. So it would appear it has smart throttle on all the time. Actual noise measuring might have to wait until the snow melts so I can take it out in the back yard with a db meter, but it was pretty quiet with no load and 500w load. The plastic case was making some nasty vibration noises though which were louder than the gen itself. when I shut it down and moved it there was a puddle of gas under it, so I'll have to pull the case apart to find where it's leaking gas too. ..update.. I fired up the AP along side my running ETQ in800i. The AP sounds louder to my ear (maybe the rattles), but also seems to be running lower rpm with no load, and has a deeper 'throatier' tone like V8 vrs 4cyl. I think I posted in this thread, results about my sound measurements on the ETQ, but basically at no load the quietest side was 58db, loudest was 64. My gut says this AP is probably close to the stated 59db (on the quietest side, with no load) When I was testing the ETQ months ago, I was able to quiet it down by about 3db on all sides by spraying the insides of the plastic panels with a couple coats of automotive undercoating. I think the all power might benifit from the same treatment based on what I heard so far. The etq had no extra space in the case, which is why I used spray on undercoat, I didn't want to block any airflow in it. The AP looks like it might have more room (without restricting airflow) that I might be able to use some thicker stick on sound deading material too. yes, Dan I did get it from ebay, came across it one day listed and I like playing with gen's almost as much as the prof, so figured I'd try this one out too. I was one of the shall we say 'early adopters' in this thread, and bought my first "powerwise 3.5kw" about the same time I think the Prof got his. (within a few pages of this topic starting) I haven't said much in this thread since, because that Powerwise just kept on humming at the race track for years for me. The motor is still running, but the gen unit bit the dust. I dont think it was any fault of the gen. My brother had a WEN brand that died on him, and I swapped AVR's trying to figure out what was wrong with his, but within hours of me doing the swap, my Powerwise died with similar symptoms as his WEN did, so I think I killed it buy swaping parts.268Views0likes0Comments
