TheCuriousOne AC transmission won't help unless a transformer is used to boost voltage, but not worth it for such a pathetic output and likely is china broken or just not meeting spec. It's likely the latter, they are crooks. Five blades means rpm are lower, this means the low speed genset is expensive and large. Doesn't look big enough. Look for 3 blade if you got 10m/s 22mph wind. btw, I'm an bsee.
Dmitry Nechaev no you actully See that there is little loss as 25 volts reach the point of measurement. you might loose voltage but you never loose current!
You can only find it by measuring resistance of the line or the voltage on the generator and consumer, right? As I saw there was only one measurement, which I remembered as on the consumer, so what voltage is on the generator is unknown. It might be 40 volts. It is the same as Chinese 12v charger can give you all 20, assuming you'll get around 12 under average loading.
With that style of blade,the return is minimal due to rotational torque needed to transmit power. A Savonius turbine is about 40% effective. Transporting power like than,your'e better off controlling,storing,then inverting to AC power,as it "Travels" better. DC drops a crapload over a short span,where 110vac loses very little unless the wire is tiny. I put my panels in the yard,instead of on the roof,and had to seriously think whether to invert across the yard and travel the 110vac,versus 40 feet of #2 copper. We went copper.
I have been experimenting with wind turbines for the last year ,and i will say i thought my turbine was no more than a wind chime until i changed the really cheap charge controller for a high quality hybrid and right now my computer which i am on and the rest of the house is running on only 8 panels and the wind generator,and so my guess is you need a quality charge controller and then you will have no problems. Its easy to get off grid 12x 2 volt batteries 8 panels and a wind generator im loving it no bill!!!
I am using an unbranded hybrid charge controller which will handle up to 600 watts of input from the wind generator side but importantly it is an MPPT controller . My first controller was a solid state controller just like the one in this clip on the floor at 105 ,and now my opinion of these solid state controllers is that they make good fishing sinkers, I will make a clip soon of my vertical axis turbine and controller cheers
WOW now that is a good test i almost bought one of these.. i did not expect it to work that bad this is rediculous! Thanks a lot this is some gold info man.
The only electronic u should buy from AliExpress is mobile Phone cases. By the way how can you expect 400watts from blades that size.? Besides, the cost of installing wind turbine generator of capacity 1kw or lower, isn't justifiable enough to even exist except for experiments and hobby. Wind turbines doesn't scale up linearly, but exponentially with increase in diameter.
400 watts probably in a 40mph wind. Keep in mind the power available in the wind goes up the square of the wind speed. 3mph is 9x and 5mph is 25x and 10mph is 100x
Force goes up by the the square of the speed. Power goes up by the third power. With such a small wind turbine you'll get 100W max at 10 m/s if it is very efficient. Higher wind speeds can lower the efficiency.
Power delivered by wind turbine is a function of speed squared so a slightly faster wind might yield more power. Turbulences from the tree could cause losses. All that being said, windfarms yield an average 30% of installed capacity (maintenance, no or low wind).
Well one reason the generator performs the way it does could be the feed cable length or foulty windings. He does have the basic parts now and with a bit of work might make it perform better
highkicker11 judging from how far away the turbine is to the house, it might well bee the wiring, having said that, 400watt is in the best of conditions very optimistic for this turbine
Glenn Littleford True, I see tons of these wind turbines near the coast of my home town. They are used to power the LED street light. From the light intensity of the street light, I figure is at 50 W ball park. So, There is no way to squeeze out 400W from a generator with this size and I don't care how you tweak it. I will say, the 400W claim shall be 40W. The problem of some seller on Ali express or alibaba is, they themself have no ideal what their product capable off...
What were you using for a load? If you were charging a 24 volt battery that wasn't completely dead, that low amperage might be possible. I'd load it with a resistive load until the voltage dropped to 22 or 23 to really see what it can do. Besides, there will be a lot of turbulence up in that tree that might reduce the effectiveness of your 10 meter/sec wind velocity. I think that the power increases as the cube of the wind speed, so going from a 10m/sec wind speed to 12m/sec would make a huge difference in power.
Nelson Bomber , I like that you are testing these import products. But I would not recommend putting a turbine in front of any object, be it a tree or a building or to close to the ground would never product good results because of air turbulence. This is why large wind turbines make more power out at sea than on land. Not as much turbulence in the airflow. 12m/s and above is the point to aim for in wind, anything below the generator will just not turn quick enough. That blade design is for whats call clean air, take it as fair away from any object as possible will create better results like high up in a pole on a ridge line for example. I am not say this will solve your issue, maybe have a read up on air flow over turbine blades and vertical vs horizontal. Coming from a engineering researcher who lives in the windiest county in Europe, wind turbines are only good if you have the right place to put them. Other wise they are totally useless waste of money. In my case a 1kw turbine in mind of a field with no tree line produces more than it advertised and it was a cheap Chinese product. The only fault I found if the generator quality is bad so it would not last long. Wish you all the best to get it working.
Air turbulence was not a problem, I ended up spinning the generator with an electric motor to see if I could get more out of it, it peaked at around 60 watts, still only 10% of the advertised output
Here's the link, www.aliexpress.com/snapshot/7306407399.html?orderId=72734064884289&productId=32284759136 would expect all those cheap chinese turbines to have similar output, I've heard similar stories about turbines from other suppliers and a confession from one supplier saying these smaller chinese turbines are just toys, better off getting a few solar panels
The output in watt is typically on a par with musical watts from cheapo products: divide by ten, you have reall watts. Nothing new! Sail on; buy ten of those and you'll have 400Watts.
*1) All small wind turbines actually achieve only 5-15% of the advertised power.* *2) 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 3-10 cents/kWh over a period of 25 years!*
Maybe they used chinese units in power. Try to convert them to SI units (simply divide by 10) :) Chinese 400 = global 40. Just like in every other products and measurement units. 20Mpixel chinese camera = 2MPixel real. etc... :)
I know this is a very late comment, I just wanted to point out that resistance increases over distance. I longer the run between generator and charger, the greater the resistance. Also, thinner wires have more resistance than thicker wires.
Yeah a basic mental calculation is that IF a pedestal fan can "screw" through a cylinder of air, giving X volume (swept area) by Y velocity, using volts x amperes = watts, then then to reverse it with say 20 or 30% losses, then 4 skinny little blades, being pushed around by a wind, through a wind tunnel, kind of like, even in ball park figures - sort of guesstimating, a BIG 60cm / 2' diameter pedestal fan will use say 50W..... to blow a strong breeze, then if I was to put that wind turbine in that air stream, I reckon it would be lucky to get 15W of that back out as power.... however if you bolted it to the front of a jet aircraft doing 900Kmh at 12,000 meters, SURE no doubt that you would get 400W out of it then....
I have the same wind turbine on my sailboat and its output daily is around 270 up to 378 watts, my cables are only 30 feet long going into a mppt controller.....
It’s actually highly variable. I’ve bought plenty of stuff off AliExpress that was completely within the spec. It just depends. Here’s a trick though: I’ve been able to get stuff free by using their own dishonesty against them. Order something that you know will be what you want even though it’s listed as being 10x what you want. Then demand a refund.
@@michaelmayfield4304 It's an interesting point. My reasoning though is that it's about changing the culture on Aliexpress so that they are not rewarded for lying. When I've done this, it's only been on items worth a few bucks. Its not the money it's the principle.
That's not typical for wind turbines unless they have bad blade configurations or pitch. It was an AliExpress purchase so that doesn't shock me. How far is the tree from the house? You could be losing voltage from distance and size of cables as well as if it's a DC turbine or ac turbine. Just some ideas. It's disappointing to see that you didn't get good performance though but that's not indicative of wind turbines :-/
I m building 1from the motor of the hoberboard ,and a 12meter antena structure tower ,😁 please sorri my inglés i'm learning , saludos cordiales desde Tijuana BC México @ju∆
A 24V battery requires that the regulator outputs ~28 VDC @ 14,3A to generate ~400 Watts. The total resistance in the wires and load should be the equivalent of 1.96 ohms to dissipate 400 Watts at 28 Volts. If you use 2 x 20 meter gauge 17 (1.04mm^2) Copper wires between the regulator and the load, you introduce an extra 0,64 ohm resistance to the system that will steal 130Watts of the total 400Watts, leaving only 270 Watts for the actual load (32.5% loss of power in the wires). The cables would also drop the voltage by ~9Volts, leaving only ~19 Volts to reach the destination (i.e. a flat 24V battery). Such a setup would be less than optimal. The moral is use short cable runs using copper wire with a big cross section.
I love your answer brother But what is the best way to set this up to realize the best bang for you buck when going with this product if I decided I want to do it my self?
@@95TurboCivic Place the turbine up and free of obstacles where the wind speed is the highest. Use short cable runs using copper wire with a big cross section. Tighten cable terminals well. That is to reduce power loss in the cables.
These were Chinese watts. Multimeter from ali express would show all of them. Besides jokes, divide all promises by 10 when buying from Chinese producer
the indicated power is almost every time for a wind's speed of 50 Km/h = 13,9 m/s. it is enormous. People don't realize. This speed is the maximum speed of your turbine, if bigger, the controler regulate turbine's speed, (brake function) if not, it's electrical annihilation of your setup, it's overcharge. I believe than if wind's speed double, his power is 4 times more, it's not proportional. these informations need to be confirmed.
Yup, DC does not like to travel, the inverter should be as close to the source as possible (in the tree?). In any case, this turbine is better suited for experimenting than actually depending on it.
Plenty thick enough. Generator output is so low, cable thickness is irrelevant. I have tested generator output at the windings on the bench with same results.
If you need 400 watts to charge your batteries, you would need to buy at least the 3,000 watts Chinese turbine.. then you got what you want. Don't be scared of over charging, as long as you buy the right voltage.. don't be scared of the price either.. 😆
Right across the street from my house, the backyards of those homes have a pretty good moving stream running through them. Boy, would I love to tap all that wasted energy..
Things you buy from aliexpress, tend to be rated in Chinese watts... 400/32=12.5, so one regular watt, equals 12.5 Chinese watts, now you know for future reference.
It might because of the wiring. Leave in 3 phase all the way up to the battery bank then convert it from 3 phase to D.C. I'll bet that's what the problem is. It's a common mistake. Remember rectify at the battery bank.
How much power does a 400 watt wind turbine produce? How much power does a 400w wind turbine produce per day? Is it safe to install it on the tree? Does the tree cuts the wind? Did you solve the low current output problem? How much was it? How big of a wind turbine is needed to power a house?
It would take 15years just to break even the cost of 250$ of the fan at 32.5W constant output in my country where electricity costs 0.06$/KW,assuming the turbine would still work at 100% efficiency on first day of powering. So i think it aint worth it and wont consider it cheap 😂
The 1.3A @ 25V are the DC output for charging a battery, right? But - - you still have the 3-phase AC from the turbine. Did you connect anything there, aside from the battery charger? You'd probably get extra power from there.
It Looks like you were tricked. When I saw the Generator i guessed you will get 40W at max. Speed. Maybe I am wrong, but I guess a 400W Generator would become very hot and would have been as big as an equal electric-motor. This Windmill Looks too tiny in my opinion. Just my thoughts of it. But congrats to buy Things from Aliexpress. Fake Things, not reliable Things, but at all very cheap. LOL
So much rubbish being sold. 10% of advertised output is just laughable. I hope it was very cheap. I bought an LED light panel with an advertised output of 100w - actual output was 55w. Based on your 10%, I did pretty well. Lol.
the same happened to me with a 500 watt 24vdc it is really disappointing and frustrating web market should make sure product they place on their webpages have a true output, I bought a Happy wind turbine and requested to be refunded I have a piece of junk with no use, I will keep searching for a working one, the worst is that they even place false review on their product line.
The wind turbine/regulator combo seems to be the "Morning Group" model S2-400W at aliexpress. It is stated in the specs (graph) that the system should generate 400W at wind speeds above ~10.8 m/s. The regulator's nominal voltage is selectable 12 or 24 VDC. It seems that you have not put enough load on the DC output from the regulator. If you did, the voltage should have dropped way below 25 VDC, which is actually a higher voltage than the max nominal 24V output. Next time try connecting a battery that is not close to fully charged :D You could try to connect a 2 ohm power resistor and then measure the voltage drop across the load while measuring the amperage going through the wires at the same time.
You said what I wanted to say, way better. I commented about the batteries having low load current too. lol. If the voltage is up then it's a problem with the load.
Measuring the distance between tips of the blads is not enough to ensure balance. You have to Balance the blades After they're setup correctly with correct distances. that means hanging the assembled blade with a string in the middle of the blade axis and check to see if the blade leans on either side ..then if that is the case you have to add some plumb and stick to the opposite side ..there is a video online that shows how it's done ...I've forgot the link.
Wire diameter to be used for the advertised??? 20A with a length of 20 meters of cable must be at least 5.73mm2, so we prefer to choose 6mm2. The calculated wire resistance at 20 meters of cable of 6mm2 is then only 0.115Ω. I prefer solar panels to.
mine lasted about 20 months then noise then ZERO output, now i have NAWS turbines.... Like You I didnt do any research or i would have never wasted my cash and time...
It's chinee junk!! All their stuff isn't worth taking a crap on! Better off building a small homemade turbine using a GM alternator. It's self exciting and reliable.
@@MartyT I bought the 24v wind turbine on Aliexpress in November, and they have already sent me 3 controllers, and with the test, none of them goes beyond 10v. The next thing I'm going to try is to put a bridge of diodes (I don't know if in English it says like this ...) Like this: es.aliexpress.com/item/32915224743.html?spm=a2g0o.detail.1000014.25.65f14774QGwayT&gps-id=pcDetailBottomMoreOtherSeller&scm=1007.13338.128125.0&scm_id=1007.13338.128125.0&scm-url=1007.13338.128125.0&pvid=ae7d0105-7d2d-4ef7-84f0-3ca6fb09c1b0
Ive watched quite a few of these wind generator videos and not a single one of them has ever approached 20% of the manufacturers rated output and when you add in the loss due to wiring,distance etc Ive concluded that they're really not worth the money or effort to procure and install... Solar panel foe the win unless one has a good stream that can be dammed up and a sluice added to spin a water generator that would make juice 24/7...
It s korrekt 400W per day not per hour! If you say these Tubin makes between 30-40 W per hour so you have 720W per day you need 4-5 Turbins for your Energy
use the parts but replace with washer motor like you did with hydro, retrofit and make a REAL turbine, seen a few people get these and find they are NO WHERE close to the rated output one man put on front of his truck to get a constant speed and it still did NOT reach close to the rated output
I usually pass these videos by. I read 30 years ago that any wind generator will never, in it's mechanical life span, ever generate enough power to pay back what it costs to build them. LOL
I purchased a 3kw wind + 2kw solar panels. Hybrid system. the solar panels outperform the wind all the time (we are 30 deg south near the coast west Australia) The 3 blades were not balanced and destroyed the bearings, Tanfon, the Chinese manufacturers would not believe that at least the 3 blades should all be the same weight!
If they put a bit more time and effort into their design they could make a very good product, I would love to give a good review on this turbine but it is hopelessly under powered
You were measuring the I (current) output, doesn't matter the distance where you take the measure, the current is the same at any section of the connection. E.g. Doubling the length of the cable make double the resistance so halves the whole current. Also how you were consuming the electricity produced?
maybe yu missed the fine print...lol.. you might need 12 if these to generate 400w... thats how some of their solar panels are sold... 300watts panel ( could well be 3 x 100 watts panel). Not all of them are fooling people but lot of them are.
I like how you made use of the instructions, not to be read but to keep the stuff off the deck. I think a lot of us are alike! Appreciate the video.

If you said this like Yoda its the best comment on here lol
Wood is renewable energy, I supplement my heating, with a wood furnace/boiler.
oh no he trimmed a tree......
He sacrificed Clean Air the tree makes and Shade just for 32 watts what a fool
So you need a constant hurricane for that thing to power the light bulb in your refrigerator???
Pretty much yep
I have the same wind turbine on my sailboat and its output daily is around 270 up to 378 watts, my cables are only 30 feet long going into a mppt controller.....
Yeah, expect ANYTHING from Aliexpress to be 1/10th what it advertises. But hey, at least it works. It's not WISH after all.
It’s actually highly variable. I’ve bought plenty of stuff off AliExpress that was completely within the spec. It just depends.
Here’s a trick though: I’ve been able to get stuff free by using their own dishonesty against them. Order something that you know will be what you want even though it’s listed as being 10x what you want. Then demand a refund.
@@michaelmayfield4304 It's an interesting point. My reasoning though is that it's about changing the culture on Aliexpress so that they are not rewarded for lying. When I've done this, it's only been on items worth a few bucks. Its not the money it's the principle.
That's not typical for wind turbines unless they have bad blade configurations or pitch. It was an AliExpress purchase so that doesn't shock me. How far is the tree from the house? You could be losing voltage from distance and size of cables as well as if it's a DC turbine or ac turbine. Just some ideas. It's disappointing to see that you didn't get good performance though but that's not indicative of wind turbines :-/
Sedated By life he needs to covert from 3 phase at the battery bank to D.C. That's why it's such a low read out.
Also he didn't show how did he measured the current.. :/
He says in other comments that he measured at the coils before the wire run.
Are the fan blades made of metal or something else?
and I was about to buy one of these. thanks
What load you have used? I see that the rpms picked up massively! What was the actual voltage when you had 1A?
Exactly! If you're trying to charge a full battery the controller will shut it right down
I m building 1from the motor of the hoberboard ,and a 12meter antena structure tower ,😁 please sorri my inglés i'm learning , saludos cordiales desde Tijuana BC México @ju∆

Hi Marty T can you recommend an alternative home wind turbine? Thanks for the video btw.
No sorry I don't know of any good ones, solar panels are so cheap these days that would be my recommendation
@@MartyT That's cool thanks man :)
A 24V battery requires that the regulator outputs ~28 VDC @ 14,3A to generate ~400 Watts. The total resistance in the wires and load should be the equivalent of 1.96 ohms to dissipate 400 Watts at 28 Volts. If you use 2 x 20 meter gauge 17 (1.04mm^2) Copper wires between the regulator and the load, you introduce an extra 0,64 ohm resistance to the system that will steal 130Watts of the total 400Watts, leaving only 270 Watts for the actual load (32.5% loss of power in the wires). The cables would also drop the voltage by ~9Volts, leaving only ~19 Volts to reach the destination (i.e. a flat 24V battery). Such a setup would be less than optimal.
The moral is use short cable runs using copper wire with a big cross section.
I love your answer brother
But what is the best way to set this up to realize the best bang for you buck when going with this product if I decided I want to do it my self?
@@95TurboCivic Place the turbine up and free of obstacles where the wind speed is the highest. Use short cable runs using copper wire with a big cross section. Tighten cable terminals well. That is to reduce power loss in the cables.
These were Chinese watts. Multimeter from ali express would show all of them. Besides jokes, divide all promises by 10 when buying from Chinese producer
Haha, that sounds about right
Marty, I hope you work on “your generator” to this tree top propeller and record it for us? BTW, great idea putting the propeller in a tree!!!!
the indicated power is almost every time for a wind's speed of 50 Km/h = 13,9 m/s. it is enormous. People don't realize.
This speed is the maximum speed of your turbine, if bigger, the controler regulate turbine's speed, (brake function) if not, it's electrical annihilation of your setup, it's overcharge.
I believe than if wind's speed double, his power is 4 times more, it's not proportional.
these informations need to be confirmed.
People doing videos doing feet yuck at least put some socks on
How long and thick was your conductor wire? could create considderable losses
DKTAz00 pric
Yup, DC does not like to travel, the inverter should be as close to the source as possible (in the tree?). In any case, this turbine is better suited for experimenting than actually depending on it.
Plenty thick enough. Generator output is so low, cable thickness is irrelevant. I have tested generator output at the windings on the bench with same results.
you're an idiot
“Long and thick” 😂😂😂
I was about to buy one of those but I won’t be now thanks for the video but I do need one hope you find a good one
I bought four of these for my Tesla and it won't stop running. I drove all the way to Australia, whoo.
fernarias for a car?
abdelmoumen bouhaouche yeah he put 4 of that on his car at last the car turn to be an aeroplane
U r high on meth or heroin?
Hi is it still working ?
If you need 400 watts to charge your batteries, you would need to buy at least the 3,000 watts Chinese turbine.. then you got what you want. Don't be scared of over charging, as long as you buy the right voltage.. don't be scared of the price either.. 😆
Right across the street from my house, the backyards of those homes have a pretty good moving stream running through them. Boy, would I love to tap all that wasted energy..
Yeah hydro is the way to go if you have access to a stream, power 24/7 means less expense on storage batteries
Things you buy from aliexpress, tend to be rated in Chinese watts... 400/32=12.5, so one regular watt, equals 12.5 Chinese watts, now you know for future reference.
Just a general thanks for going to the trouble to save people form getting conned.
It might because of the wiring. Leave in 3 phase all the way up to the battery bank then convert it from 3 phase to D.C. I'll bet that's what the problem is. It's a common mistake. Remember rectify at the battery bank.
rec/reg Controller is at the battery bank
How much power does a 400 watt wind turbine produce? How much power does a 400w wind turbine produce per day? Is it safe to install it on the tree? Does the tree cuts the wind? Did you solve the low current output problem? How much was it? How big of a wind turbine is needed to power a house?
It would take 15years just to break even the cost of 250$ of the fan at 32.5W constant output in my country where electricity costs 0.06$/KW,assuming the turbine would still work at 100% efficiency on first day of powering. So i think it aint worth it and wont consider it cheap 😂
The 1.3A @ 25V are the DC output for charging a battery, right? But - - you still have the 3-phase AC from the turbine. Did you connect anything there, aside from the battery charger? You'd probably get extra power from there.
I thought you were going to takeoff at 3:29 Nelson. Great video. Thinking of buying myself these turbines.
you should buy it, install it in the right way and it will work...
It Looks like you were tricked. When I saw the Generator i guessed you will get 40W at max. Speed. Maybe I am wrong, but I guess a 400W Generator would become very hot and would have been as big as an equal electric-motor. This Windmill Looks too tiny in my opinion. Just my thoughts of it. But congrats to buy Things from Aliexpress. Fake Things, not reliable Things, but at all very cheap. LOL
So much rubbish being sold. 10% of advertised output is just laughable. I hope it was very cheap.
I bought an LED light panel with an advertised output of 100w - actual output was 55w. Based on your 10%, I did pretty well. Lol.
the same happened to me with a 500 watt 24vdc it is really disappointing and frustrating web market should make sure product they place on their webpages have a true output, I bought a Happy wind turbine and requested to be refunded I have a piece of junk with no use, I will keep searching for a working one, the worst is that they even place false review on their product line.
The wind turbine/regulator combo seems to be the "Morning Group" model S2-400W at aliexpress. It is stated in the specs (graph) that the system should generate 400W at wind speeds above ~10.8 m/s. The regulator's nominal voltage is selectable 12 or 24 VDC. It seems that you have not put enough load on the DC output from the regulator. If you did, the voltage should have dropped way below 25 VDC, which is actually a higher voltage than the max nominal 24V output.
Next time try connecting a battery that is not close to fully charged :D
You could try to connect a 2 ohm power resistor and then measure the voltage drop across the load while measuring the amperage going through the wires at the same time.
You said what I wanted to say, way better. I commented about the batteries having low load current too. lol. If the voltage is up then it's a problem with the load.
Measuring the distance between tips of the blads is not enough to ensure balance. You have to Balance the blades After they're setup correctly with correct distances. that means hanging the assembled blade with a string in the middle of the blade axis and check to see if the blade leans on either side ..then if that is the case you have to add some plumb and stick to the opposite side ..there is a video online that shows how it's done ...I've forgot the link.
please for your own safety, wear some shoes!
Wire diameter to be used for the advertised??? 20A with a length of 20 meters of cable must be at least 5.73mm2, so we prefer to choose 6mm2. The calculated wire resistance at 20 meters of cable of 6mm2 is then only 0.115Ω. I prefer solar panels to.
CCC = Cheap Chinese Crap. Along with 100AH power banks, 20,000 lumen torches, 2TB MicroSD cards and counterfeit phones.
mine lasted about 20 months then noise then ZERO output, now i have NAWS turbines.... Like You I didnt do any research or i would have never wasted my cash and time...
It's chinee junk!! All their stuff isn't worth taking a crap on!
Better off building a small homemade turbine using a GM alternator.
It's self exciting and reliable.
Chinese controllers dont usually work properly. Measure the output voltage on the controller without connecting it to the batteries.
Yes I tried that, still low output but ac instead of dc
@@MartyT I bought the 24v wind turbine on Aliexpress in November, and they have already sent me 3 controllers, and with the test, none of them goes beyond 10v. The next thing I'm going to try is to put a bridge of diodes (I don't know if in English it says like this ...)
Like this: es.aliexpress.com/item/32915224743.html?spm=a2g0o.detail.1000014.25.65f14774QGwayT&gps-id=pcDetailBottomMoreOtherSeller&scm=1007.13338.128125.0&scm_id=1007.13338.128125.0&scm-url=1007.13338.128125.0&pvid=ae7d0105-7d2d-4ef7-84f0-3ca6fb09c1b0
Ive watched quite a few of these wind generator videos and not a single one of them has ever approached 20% of the manufacturers rated output and when you add in the loss due to wiring,distance etc Ive concluded that they're really not worth the money or effort to procure and install... Solar panel foe the win unless one has a good stream that can be dammed up and a sluice added to spin a water generator that would make juice 24/7...
I like the point where you said tree can be used as poles. Thank you for sharing this information
Looks cool, nice video. I loved your idea of pruning the trees and putting it between, very stealthy.
Yeah no council DA required
Many street lamps in china have this wind turbines. They all broke down after a few weeks
It s korrekt 400W per day not per hour! If you say these Tubin makes between 30-40 W per hour so you have 720W per day you need 4-5 Turbins for your Energy
use the parts but replace with washer motor like you did with hydro, retrofit and make a REAL turbine, seen a few people get these and find they are NO WHERE close to the rated output
one man put on front of his truck to get a constant speed and it still did NOT reach close to the rated output
How long was the power cable? You lose a significant amount of power over long distances.
I usually pass these videos by. I read 30 years ago that any wind generator will never, in it's mechanical life span, ever generate enough power to pay back what it costs to build them. LOL
Sounds about right, better off with solar these days
The distance from wind turbine to house should be about 100m.then the cable should be ticker.try again.good luck
The problem with wind turbines is you need u=11 m/s for 75% of the time and clean air flows. Forests are unsuitable
I haven’t watched all the video yet, but based on comments, your device success rate has improved over the years. Less new crap, better results.
I purchased a 3kw wind + 2kw solar panels. Hybrid system. the solar panels outperform the wind all the time (we are 30 deg south near the coast west Australia) The 3 blades were not balanced and destroyed the bearings, Tanfon, the Chinese manufacturers would not believe that at least the 3 blades should all be the same weight!
If they put a bit more time and effort into their design they could make a very good product, I would love to give a good review on this turbine but it is hopelessly under powered
you could throw it in the creek and use it as water driven turbine for a minute
Iske price kitne hai
How much is it? Thinking of just buying it for the blades and the pivot mechanisme and installing it on a washing machine motor
Is the capacity the same as the announcement manufacturer?
No only around 10% of advertised output
even an idiot would have understood before buying that those plastic shitty tiny weak blades could not generate 400W
Long cables = Resistance = Voltage drop + Current (Ohms Law)
Read video description, cable loss was calculated less than 5%
Nooooooooo el árbol!!!
your setup was wrong. I don't think you can have a very long wire for dc setup.
The output was measured at the turbine before wiring, the output was so low there was very little cable loss
Nelson Bomber that really terrible lol. I doubt it ever spin that fast where I live. Good to know that you measured it at the source
You were measuring the I (current) output, doesn't matter the distance where you take the measure, the current is the same at any section of the connection. E.g. Doubling the length of the cable make double the resistance so halves the whole current. Also how you were consuming the electricity produced?
Cost??? Indian Rs-???
@@rnamma Agreed. He never states the load resistance. The current draw is directly dependant on the LOAD resistance.
Tree as Tower?! It bends (you loss energy with the swinging), block your Wind and generate turbulence around...
how do u block/generate turbulence?
exactly... better to put in the living room and blow with the whole family... 😂🙈
maybe yu missed the fine print...lol.. you might need 12 if these to generate 400w... thats how some of their solar panels are sold... 300watts panel ( could well be 3 x 100 watts panel). Not all of them are fooling people but lot of them are.
Pretty white blades,not your fault bro. Just shitty products, I'd demand a refund
So ive seen many of these turbines bearings fail due to excessive wind, is there a clutch of some sort for this situation?
