I have an accurately rated 3000w Chinese turbine and it weighs well over 200lbs. weight is a good way to judge the ratings of all these different wind generators.
Yes, absolutely. I ordered a 800W turbine from a more reputable supplier and the difference in weight is very noticable. The 800 is about twice as heavy as this supposed "1.2kW".
2 years back i purchased a 48v 3500w wind generator and was suspect regarding the cable size from the generator so i test benched it to fined it was a 48v 35w only 3465w short i demanded my money back and after showing them the test i got it nothing but garbage i do not recommend any Chinese wind turbines . and the market is flooded with them
There was another guy here on CZcams (John Daniels) touting about how great some of these Chinese made wind turbines work. It's interesting to see his in action and producing such good results. I don't know if there was some other forces at work here hyping the outcome, but it certainly is a head-scratcher seeing the differences in the results. Anyway, I have been advised by a retailer of wind and solar products NOT to invest in any of the 'imported' wind turbines, but if you really want to go the wind route to add to your solar array, then you'll need to spend thousands. Just my thoughts. Great video debunking falsehoods.
I have bought one of these that John Daniel mentioned, and after a year in use I can say it's exaxtly what it says it is. I got the 500w chinese turbine, and I ve seen 600w on 28 mph winds. Totally happy with it. It goes around 350 dollars these days on aliexpress.
I bought one from the seller that John had bought off the turbine doesn't make any power i sent the seller a couple of videos he wasn't interested and in helping me find a solution very frustrating 😑
Nice to have someone like you out there doing tests on these turbines , you will save a lot of us money getting scammed I'd like to hear what you think us that inverter there?
You were more than kind in you review of this product. Most would have roasted them because of their blatant lies. Anyhow we tend to have had the luxury of UL & CSA testing all of the products that we buy to alleviate scamming like this.
I used to think wind energy, especially VAWT. After seeing many turbines turning, I wanted to really know how much they produce. And eventually I found the company flower turbines publishing scatter plots of their turbines. It was an eye opening experience, as they just told the truth: the small ones really don't produce a lot of energy. A spinning turbine doesn't mean power, the plots show it has to get windy to get any ROI on it. And that's what they say: first test your environment and always augment with other means. Another thing they showed is that you need a cluster of VAWTs to get more out of it. But yeah, wind turbines usually are disappointing.
@@williamwofford4919 I've just purchased a 2kw istabreeze, really wondering how good that grid tie inverter is you have there? it's looking like options are limited and I've seen complaints about it, however yours seems to be working ok. are you using it with your istabreeze and would you recommend?
@@williamwofford4919 It's very easy to 'hack' this blue inverter. If you open it up, you will see that the very first component is a 3 phase bridge rectifier. You'll see that the positive output of the rectifier is connected to one of the dump load outputs. (so this means you have a positive terminal) If you connect a (substantial) cable up to the other (negative) terminal on the rectifier and feed that out of the box, then you can connect some PV panels and use the inverter to produce useful power on non-windy days. The thing to remember is that the maximum input voltage is 90V so only two panels in series (most panels are 40V or less). I have this exact box and a 500W max turbine and I connect 6 PV panels (3 parallel pairs of 2 panels wired in series). There's no problem having the turbine and the panels working at the same time- just put a couple of PV diodes to prevent the turbine feeding back to the PV array. Can send info if you like.
Is it necessary to bypass the rectifier? surley it would sort out the polarity of current coming in, I tried it with one of my 3phase inverters just connected the two leads to two of the inputs and it worked fine but was a bit nervous and only used it till a new solar inverter arrived.
That’s the first time I’ve seen one of those turbines rated at 2000 watts. Normally they call them 400 watts, which is still over rated. I wish there was standard wind speed for turbine ratings. Your turbine probably has a 1 meter rotor. I have a new turbine coming that is also rated at 2000 watts. It’s rotor has a 4 meter diameter. It will produce 2000 watts in a 23.5 mph wind.
very impressive testing, thank you for that, I have grown to accept 50% efficiency from [ahem] over seas manufacturers however anything below that is very disappointing indeed
If the stator coils were air core, then the output would continue climbing even though the blades would have flown off at the higher revs. So this is an iron-cored stator to make the most of the PM's at low speed. The original idea was for slow and steady wind turbines, no iron means no cogging and can use our UK low wind speed average on a short tower. We expect too much, it's just a little bit of standby power or small well-water pump thing. 2kW is a serious pylon 4 metre blade installation.
I have a ista breeze i 2000 and it has 2.2 metre blade span, iron cored, quite bad cogging compared to my home built air cored turbine which starts in almost no wind. The ista breeze takes quite a bit more wind to start but I have seen 1700 watts from it, wouldnt want it go much faster than that, the most I have seen from my home made is about 900 watts with a similar blade size also home made but far less efficient I think. Maybe one day I will swap blades but ballancing would be really difficult on a machine that cogs I think. I use the same gridtie inverter type, one rated at 1 kw and the other at 2kw
The Chinese manufacturers don't lie, they are rating the turbines on the American regime of instantaneous power. IE shorting the turbine at rated rpm and recording the shorted amperage by the rated voltage or sometimes by the open circuit voltage. The EU adopted the BS standard years ago which is a continuous output at 10.5 M.S.
In fact it is a 500 W one selled as a 2000 one. But if people pay only 200 to 400 euros for this turbine it is a very good bargain in fact. just buy 4 of them and voilà, you pays a lot of times less than a real 2 KW European one.
I can tell you for sure! This is definitely not a 2000W product. 2000W products cannot be so small! Chinese people are always selling fake products on e-commerce sites! You should buy direct from the manufacturer.
Thanks William i am in the process of waiting for one to turn up if its not going to perform as rated i can ask eBay to step in as false advertising is selling by deception and ethically they are breaking the law so i will be conducting tests which i assume will probably yield similar to your own findings .
I have been flying our 2kw Yenzhou Shenzhou wind turbiesince 2008 Replaced bearings after 2 years an downrated it to 1.5w with smaller blades. Touch wood.
*All practical tests show that small wind turbines hardly generate any electricity. And only at costs above 1$/kWh!* There is hardly any wind near the ground. And it is also very gusty, which extremely reduces the service life of the systems. *With solar systems, you can reliably generate electricity for about 8-12 cents/kWh over a period of 25 years!*
did you checked open circuit voltage at 1500rpm? this turbine is solid 500W on Chinese market. I did import them as such. AC voltage was abt 70-90V. For me they were ok as 12/24VDC systems( occasionally controller can blow off if battery weren't connected). try to do test with resistive load. like 5ohm?
Falsely rated as many are, obviously as genuine 2kw turbines are far bigger and heavier and cost alot more, ebay contiuosly allows false advertising , weve all been scammed
I can tell you right off the hop, that is not a 2000 W turbine. Lol it might have 2000 W before it blows up at 65 m/s wind or 150 miles an hour. In my opinion a 2000 W wind turbine should have a blade diameter close to 3.2 m or 10.5 feet. This was my guess one minute and 30 seconds into your video. Lol, when I finish the video, I wasn't surprised that you got maybe a 300 W Turbine. I do like your set up for testing. What would be more interesting is what would the wind speed need to be to even get 500 W.
The mentioned product was once obtained but it has not been able to work, the input DC indicators are correct, the output AC output showed a little at first, but at the moment the reading is practically zero?
I think a lot of these Chinese retailers really don't know anything about the products they sell. If you compare that one to others of a similar size I think it is a 400 watt unit.
Good test sir So it is true that chinese wind turbine has a fake rated Like the cheap chinese inverter welding machine It says that the inverter welding machine is 400A But it is only 200A It is not bad to tell the true rate of a product If the price is right But telling a lie about the product is a scam and bad idea If the product has a good quality but the rate of the product is not true The product becomes a bad product Salute to you sir Hope that your channel Will grow
I had the same problem with solar panel fro China rated at 300 watt and out of two different Supplers of panel the best I got was 100watt no were near the 300 watt they are sold as. We wourned.
Yes the Chinese do use these crazy numbers, this is maybe a 300w turbine, Interesting to see it go that RPM , probably would never see those RPM in real life, I have 3 Chinese turbines they weigh between 10kg & 15kg, its the best way to tell, a 1kw turbine might be over 30KG etc. There is plenty of junk out there and its good to expose it ! .
poor dude, most Chinese Watt labels are HIGHLY exaggerated (be it on wind turbines or inveters and converters or powers supplies) ista breeze! the only one that is kind of producing as much as labeled is the (also China) produced ista-breeze series :D but thanks for testing that crap! X-D preventing hopefully from precious resources to be wasted. have you found a good solar + wind + battery charge controller? :D (there are SOOOO MANY X-D and the Chinese support is crap and most do not have vendors in Europe... so everyone sooner or later spends the extra money and goes back to Victron)
Thanks bro super nice video . By the way I live in Tarfia Spain maybe one of the best places to use wind as a energy source . Which is your recommendation?
Typical rubish from Ali,Wish etc. Actualy for this price is only housing value 😀 I last time buy this aslo and for 1000W has a 300W on wall. So i fu*k off the original chinese generator from turbine inside and change for 1000W AC servo Daikin. Now working without problem.
Good video In my opinion any generator if it does not exceed at least 1000 rpm will always have a lower than average efficiency, to make this possible you need to mount larger blades and a speed multiplier. To have a lot of strength we will lose a few laps but we would have more torque immediately. It is necessary to use a multiple even greater than 6. What do you think, engineer? Let's think of the old windmills ..
Great video , keep up the good work . I am planning to move to Sevastopol and I believe the average wind there is about 11MPH and I want to set up a 24V system , do you know of any decent 24V windmills that would produce a useful amount of power (=> 250 W ) at 11MPH ?
I know the company in India which makes wind turbine, 1800 watt, low rpm of 50 or 60 , 48 v, 50-60 hertz Single phase Owner email id is jaykumarpatel05@gmail.com
@@tujuprojects No Biden signed a law into effect making it illegal for Americans to spend money in Russia so I have changed my destination to Bishkek , I am very close to being ready to move , it should be within the next 6 months.
Its probably a 200w device with a typo or just purposely added a zero. Happens a lot but to be honest not sure how much you can trust the power rating of that transformer
The 'vertical lantern style' are advertised at between 400 to 4000 watts are lucky to output 40 watt at 25 knots of wind. It is a scam, not a faulty device.
Did you ever buy the atlas cause I just got mine today. There’s a guy named DL who has some videos About the atlas. He’s on his second one.didn’t see his final result though
Thank you very much, but what I didn't get is how to convert the RPM into wind-speed needed for this RPM of the rotor. I found also exact this Grid-tied Inverter, and looking for about 500 to max 1000 Watt getting from wind, as then in the night my basic usage might be covered. My expected wind-speed as of nearby Lampuhn (Thailand) Airport in 10 Meter high (I install at 12 meter) is average most 2 (4 months with 4 m/s).
"You pays your money, an' you takes your choice". I rarely trust and Chinese electronics unless qualified by someone I trust. I paid a lot more for a 1Kw turbine built by FuturEnergy which is a UK company, all castings, bearings and wiring manufactured also by UK companies for them. It's worked beautifully for years in the wilds of the Cumbrian fells, and has weathered many a squall reliably. And the customer service is second-to-none. Sick of Chinese manufactured rubbish.
I would have thought it was the wind turbine the little ones are generally 500W but the wattage gets exagerated to win the sale. Try it on an Ista-Breeze 2000W we know they can reach it.
Hoping the Non Wind inverters hold up? mine is running 1500 watts with 20 100w Panels, hearing they crap out after 2 years and that the LCD don't hold up!
dam I bought one a year ago and haven't hooked it up they suck... Mine is 230 volt been trying to figure out a way I can lower it I live in Florida I don't want to be climbing up on the roof every time there is a warning of a hurricane. I saw one one time that split in half and bent over. probably don't have to worry about blowing anything up.
That is the 400W model. It is sold as a 400W by credible sellers. You probably bought it from a dodgy seller who labelled it 2000W . A 1,000W generator (let alone a 2,000W one) is a gigantic thing.
But ...the output of the inverter should be connectrd to loads...thrn only input power will increase....in solar inverter if iam not losding thr output ..thr dc voltage snd low current will show.....upon hiving load...more current it will draw from solar panel
@@williamwofford4919 Thanks for your reply..there are 2 points to suspect ..did u find the output from the wind generator itself is low(even the rpm is increased) or the disability of the grid tie inverter?
Great video. What is your oppinion on the inverter that you used in the test? Did you have to modify the dump load that came with it? I've seen some other videos where the same inverter would not allow the turbine to spool because it was always diverting power to the dump load circuit sort of like putting on the brakes all the time.
you need to add more to the dumpload, a metre of nichromewire AWG20 works pretty well, wind it round a bit something non flamable and insulating like some plaster board, reduce the dumpload voltage to about 65 and it should be fine. Its charging up capacitors that puts a drag on it starting. Also once its triggered the over voltage it stays on for a few minutes to lower the voltage then you hear a click as the relay opens again and it will spin up again, unplugging it will speed things up a bit but whenever they start up they have to charge capacitors first and that slows them down. If that didnt happen it would just go straight into over voltage again. The system cant cope with a lot of power coming in quickly like a strong gust of wind.
I'm going to build my wind turbine soon because I don't trust the one from the Chinese. The equipment will produce 2400 watts at 10 meters per second, diameter 3.6 meters, maximum revolution 260 RPM with variable pitch control by centrifugal force, I will use a 24 volt 100 A bus alternator and a speed multiplier of 14 to 1.
Any decent machine shop should be able to make up an adapter for you :) I would go down this route otherwise any imbalance might cause extra strain on the bearings!
@@williamwofford4919 people bash mw&s windturbine but I've be using the single core for 3 years plus and the output is excellent it putting out over 1300watts
if its the same price as a 500w its probably a 500w. same size as a alternator 2oo0 walts come on. people got to research befor you buy not after. buying on aliexpress hello
Brilliant...I was not expecting to see such a professional testing setup ..
I have an accurately rated 3000w Chinese turbine and it weighs well over 200lbs. weight is a good way to judge the ratings of all these different wind generators.
Provide link to it
Yes, absolutely. I ordered a 800W turbine from a more reputable supplier and the difference in weight is very noticable. The 800 is about twice as heavy as this supposed "1.2kW".
What’s the link
Let’s see the test 🤔😂
That's right,,more weight is more reliable
2 years back i purchased a 48v 3500w wind generator and was suspect regarding the cable size
from the generator so i test benched it to fined it was a 48v 35w only 3465w short
i demanded my money back and after showing them the test i got it
nothing but garbage i do not recommend any Chinese wind turbines .
and the market is flooded with them

haha look at the size of the unit, there's no way that's supposed to be a 2k. It's just a 400 with a fake listing rating.

You were more than kind in you review of this product. Most would have roasted them because of their blatant lies. Anyhow we tend to have had the luxury of UL & CSA testing all of the products that we buy to alleviate scamming like this.
I've bought one that looks the same. Said to be 800W. It produces 30W.
Ohh😮😮,, they simply put labels of different wattage
On the wind turbine website they state 4000w is over a 24 hour period Max output. Not the actual output. I got caught as well.

with solar panels and wind turbines you have to calculate that throughout the day
So at that curve and some bar math, to reach its rated power you would need windspeeds of 1875m/s. or about 27 times the highest recorded on earth.
Thank you sir .... you made my day...
I can tell you for sure! This is definitely not a 2000W product. 2000W products cannot be so small! Chinese people are always selling fake products on e-commerce sites! You should buy direct from the manufacturer.
The voltage is not increasing during increasing the rpm. It's still freeze around 65 volt. Normaly voltage and rpm still correlate...

Good test sir
So it is true that chinese wind turbine has a fake rated
Like the cheap chinese inverter welding machine
It says that the inverter welding machine is 400A
But it is only 200A
It is not bad to tell the true rate of a product
If the price is right

Will grow

@@leafenvironment3712 Thank you but I have committed to a 30V nominal electrical system because I can dispense with electrical safety equipment.
Are you still going to Sevastopol?
@@tujuprojects No Biden signed a law into effect making it illegal for Americans to spend money in Russia so I have changed my destination to Bishkek , I am very close to being ready to move , it should be within the next 6 months.
@@robertlackey7212 they occupied it 2014 already, maybe you missed that.
Its probably a 200w device with a typo or just purposely added a zero. Happens a lot but to be honest not sure how much you can trust the power rating of that transformer
The 'vertical lantern style' are advertised at between 400 to 4000 watts are lucky to output 40 watt at 25 knots of wind.
It is a scam, not a faulty device.
Yes Chinese crap but people want cheap shit then get stung
Thanks for the vid 👍🏻👍🏻👍🏻✌🏻
Thanks man !!! For telling us that .
Subscribed. We need more people like you doing this. Nice setup. Where are you based? as I'm about to buy the Tesup ATLAS2.0 Wind Turbine.
Did you ever buy the atlas cause I just got mine today. There’s a guy named DL who has some videos About the atlas. He’s on his second one.didn’t see his final result though
Thank you! using the kit at work for these tests makes things like this possible. Based in Worcestershire UK
Tesup is just a bigger scam than Chinse products !
Thank you very much, but what I didn't get is how to convert the RPM into wind-speed needed for this RPM of the rotor.
I found also exact this Grid-tied Inverter, and looking for about 500 to max 1000 Watt getting from wind, as then in the night my basic usage might be covered.
My expected wind-speed as of nearby Lampuhn (Thailand) Airport in 10 Meter high (I install at 12 meter) is average most 2 (4 months with 4 m/s).
NIce test !!!!!!
Any recent vertical wind turbines tested?
good tests. Thanks for saving me some money. Can you recommend a good starting point to set up a wind turbine?
I have had good success with the ISTABreeze 2kw turbine, seems to be rated correctly!
the "windsafe" 2wk istabreeze would be even better.
Awesome test
Thank you!
"You pays your money, an' you takes your choice". I rarely trust and Chinese electronics unless qualified by someone I trust. I paid a lot more for a 1Kw turbine built by FuturEnergy which is a UK company, all castings, bearings and wiring manufactured also by UK companies for them. It's worked beautifully for years in the wilds of the Cumbrian fells, and has weathered many a squall reliably. And the customer service is second-to-none. Sick of Chinese manufactured rubbish.
I would have thought it was the wind turbine the little ones are generally 500W but the wattage gets exagerated to win the sale. Try it on an Ista-Breeze 2000W we know they can reach it.
yep i went to an istabreeze with much better success!
Hoping the Non Wind inverters hold up? mine is running 1500 watts with 20 100w Panels, hearing they crap out after 2 years and that the LCD don't hold up!
dam I bought one a year ago and haven't hooked it up they suck... Mine is 230 volt been trying to figure out a way I can lower it I live in Florida I don't want to be climbing up on the roof every time there is a warning of a hurricane. I saw one one time that split in half and bent over. probably don't have to worry about blowing anything up.
Thank you
merci pour cette belle video , c est que du reves toutes ses eolienne domestique
Excellent Engineering. Did you ever test one (Turbin) that works and you recommend?
Thank you!
The most rpms in about 20 mph is about 400 to 500 rpms so maybe 100 watts.sad right.15 mph about 40 watts.
Yep its pretty pants. probably ok for near shore or remote islands ect but solar wins every time.
That is the 400W model. It is sold as a 400W by credible sellers. You probably bought it from a dodgy seller who labelled it 2000W . A 1,000W generator (let alone a 2,000W one) is a gigantic thing.
Hello William.
How successful has this inverter been for you. I see bad reviews / experiences with them.
Thanks in advance
But ...the output of the inverter should be connectrd to loads...thrn only input power will increase....in solar inverter if iam not losding thr output ..thr dc voltage snd low current will show.....upon hiving load...more current it will draw from solar panel
No - the output was grid tie so it can push as much power as it gets from the wind turbine. the grid is the load
@@williamwofford4919 Thanks for your reply..there are 2 points to suspect ..did u find the output from the wind generator itself is low(even the rpm is increased) or the disability of the grid tie inverter?
wind generator was low output - the inverter has done 2kw since i changed to a different brand. @@prabhu6330
Great video. What is your oppinion on the inverter that you used in the test? Did you have to modify the dump load that came with it? I've seen some other videos where the same inverter would not allow the turbine to spool because it was always diverting power to the dump load circuit sort of like putting on the brakes all the time.
I found it worked really well, once the dump load was changed. it doesnt dump until it the voltage was getting high from excessive windage
you need to add more to the dumpload, a metre of nichromewire AWG20 works pretty well, wind it round a bit something non flamable and insulating like some plaster board, reduce the dumpload voltage to about 65 and it should be fine. Its charging up capacitors that puts a drag on it starting. Also once its triggered the over voltage it stays on for a few minutes to lower the voltage then you hear a click as the relay opens again and it will spin up again, unplugging it will speed things up a bit but whenever they start up they have to charge capacitors first and that slows them down. If that didnt happen it would just go straight into over voltage again. The system cant cope with a lot of power coming in quickly like a strong gust of wind.
What's your verdict on on the inverter that you are using as the power display. Would you say that is ok for the UK grid?
I'm going to build my wind turbine soon because I don't trust the one from the Chinese. The equipment will produce 2400 watts at 10 meters per second, diameter 3.6 meters, maximum revolution 260 RPM with variable pitch control by centrifugal force, I will use a 24 volt 100 A bus alternator and a speed multiplier of 14 to 1.
Cost? For what's usually marketed as a 300 or 400w unit, that's actually pretty ok.
if it was marketed at this then maybe... but you'd be pretty annoyed if you paid for a 400hp car and it turned out to be 40!
@@williamwofford4919 but you didn't answer the question of cost.
@@thedavesofourlives1from memory it was couple hundred pounds, the proper istabreeze one was 400 so hardly that far out
Mine hits 1200 will be doing a test later will let you know I have a insta- breeze i 1600!
Istabreeze are good! :D
this is still relevant, just divide by ten what ever they claim.
Great job, thx;)
Here we call it "false advertisement" worthy of a lawsuit !
I have the same problem but the Chinese company name is(Foshan Mars Solar Technology Co.,Ltd)
Hi. I would kindly ask you, What i the best way to connect the alternador axis to homw made (VAWT) wind turbine? any suggetion??
Thanks
Any decent machine shop should be able to make up an adapter for you :) I would go down this route otherwise any imbalance might cause extra strain on the bearings!
have you try to rewind one of the chinese made wind turbine to increase the output?
Can you test a good quality altenator as well and compare.
What is the rated output of the turbine you are using?
Sorry. I thought you were testing the inverter.
Thank u
This mounted in the roof have max power 200W
Max rpm with wind 3blade is around 600 chek power with 600rpm ? Best regards
we checked at 1000RPM, which was already too low.
This one is a 400watts,2000 watts is big
that tiny windturbine is certainly never is able to produce 2000 watt , yust because the inverter is rated 2000 watt , the turbine is not
Maybe 2000 wpd (24h)
😢it looks like a 250 Watt generator 😮😮
Just by the size of that turbine you should have known u cant get 2000watt it's the same size of most 400watt turbines
possibly. difficult to see the size when a first time buyer!
Did u get a refund
@@fadajuiceful partial refund. Then sold it correctly listed as a 400w, so didn't loose too much
@@williamwofford4919 people bash mw&s windturbine but I've be using the single core for 3 years plus and the output is excellent it putting out over 1300watts
Where are British Standards on Imported Goods
if its the same price as a 500w its probably a 500w. same size as a alternator 2oo0 walts come on. people got to research befor you buy not after. buying on aliexpress hello
