This is a commonly available turbine that you can see all over your favorite websites. I got this one off eBay and it was literally the cheapest one.
If you have any questions about this setup please feel free to ask, and if you have any suggestions I would love to hear them. Thanks!
Thank you sooo much, I just bought a cheap discounted 400w wind turbine that I got at the end for 50 USD, down from 230 ! I plan to spend one full year, winter included, in North artic circle in Norway... and have the wind turbine recharging my lithium battery for the lightning inside the van...
Main heating inside van from LPG (water boiler & kitchen) and diesel (air heater).
After 10 months how is the 400 watt turbine doing
The blades twisted opposite way towards the end. Is to help deal with adverse vortices generated along the length of the wing. This is incorporated in aircraft propellers and aircraft wings of certain designs
I'm still on and off about getting a small turbine. I have a "DIY-ish" renewable system, the heart of it is a Bluetti AC200Max, though, I'm just going to Heath Robinson up a bunch of cheap flex panels eventually, and probably store the excess in ordinary LiFePo4 batteries, not Bluetti's own ones (which cost almost as much as buying a second unit!). Might try it, now!
Hello. the 700w turbine seems to work well. Have you the name or a link to this turbine ?
Question, you mention you are using romex wire from the turbine, are you using solid conductor or stranded? Watched another youtuber video and he said solid doesn't work well, but if that is what you are using it seems to work fine.Thanks
How about a two-year review on this set up?
Hi thank you for your content, can you recommend a good Chinese wind turbine aboutb1000 watts that is quite And rely able.
Regards Martin steele
Good Information --- THANKS
I have one like this with the propeller no current and when i took of the propeler working good i try it in the garage wit the brass
Please help to recommend with aliexpress link
Thanks so much for this video. In your setup of three turbines, one of them went over 1000W, wouldn't that damage the 1000w inverter since the total power produced is way over 1000w? How do I know my inverter could handle the power the turbines will give?
Hi Noodler! Thanks for watching! Every watch and every sub really helps me out right now! The batteries are where the excess wattage comes into play. That's why I have them. The batteries are like shock absorbers or rubber bands. Whenever the turbines producing more than the inverters can use, the batteries take that load. It is important to remember, though, that I'm not nice to my batteries...doing it this way, if you want your batteries to last a long time, you will need to use something called a dump load controller which will essentially shut your turbine down, or brake it, when it starts producing more power than is being used. The inverters are never going to suck up more wattage than they can process. It's easier to think of them as someone standing above a cup and drinking from it with a straw. Even if gallons and gallons are dumping into a 7/11 Big Gulp, you're only going to suck up what you want. The only way the inverters can really be damaged is if they're hit with a large voltage spike...that sometimes messes them up.
@@ToysforWattsThanks for the clear explanation. I'll include a dump load controller in my system for safety, and probably use a grid tie inverter with a limiter as well.
@@bluestweaks77 water heaters make for a good dump load also
Is that the delta wing blade 630mm ? If so are they any good compared to standard
I didn't measure them specifically but the rotor diameter was roughly 48 inches (1.25m). That style of blades is FAR superior to the standard blades found on most Chinese turbines. The only issue I had with them were they had a slightly poorer slow speed startup...it took a little more wind to make them go, but while they were working they made more power and ran quieter.
The wiring at the base of the turbine.... does it matter what is hooked up where? Trying to figure out which one is the ground.
There is no ground. It's three phase AC current. All three phases will need to go to a bridge rectifier (unless you have charge controller or inverter that accepts three phase input.
I want a good starter turbine starts in low wind that won't break the bank . Sujestions?
what are your goals for the turbine? The iSta Breeze i1500 is easily the best cost per watt ratio out there in terms of wind turbines. It'll cost you roughly $400 USD and is a solid workhorse.
Are you putting 40+ volts directly into your 12 volt batteries? Does that damage them? Or do you have some type of voltage regulator like cars use?
I haven't watched this video in quite some time, I don't think this turbine would have had the power to kick voltage up to 40vdc on a 12v battery...at any rate it was a 24v turbine. It "might" have managed to get up to 40v on a 24v bank but only briefly. In general, though, I'm very mean to my batteries for the sake of testing and demonstrating the peak potentials of the turbines I work with. Always use a charge controller appropriate for your own application :D
OK so I hear the complaints about this little 400W turbine. Your video shows it actually puts out juice when it spins. Show me a little 47" turbine alternative that performs better. I want to know.
The scoop on the blade is built in over speed protection to push the blades out of the wind
In low wind conditions hacking off the blade tips might help haha. Someone should make a 3d printed aftermarket blade design with differing geometries depending on your wind speed ave and max.
I just bought one of these wind generator for my sailboat. So far everything out of the box is great. EXCEPT the instructions. Three white wires? Coming out of generator? What is what? Red, black and three green wires coming out of the controller. What are the green wires?
Hi Howard! Thanks for watching! Every watch and every sub really helps me out! The instructions are meant to be thrown away...they don't think anyone reads them. The turbines produce three phase AC current so all three of the leads coming from the turbine itself are all paralleled outputs. There's no polarity or anything. The three green wires on your controller are the inputs...they connect to the three white wires from the turbine. It doesn't matter what order they're in, but all three legs are required. There's a rectifier inside the controller that will turn the three phase AC current into DC current (your red and black wires).
@@ToysforWatts Thank you very much! That explains it. I do not expect expect a lot out of this generator. But when it windy and cloudy. Hope to get the batteries charged in the boat.
hows it working? Im a live aboard looking too! TY
how long is your wiring from the turbine to the controller? mine just produces 25 to 50 watts.. not sure if its because the wires are too long (almost 50feet)
For this particular turbine the wiring is less than 20ft. Can you post a link for which turbine you're running? What is the battery arrangement you're hooking up to?
@@ToysforWatts here is the link
a.aliexpress.com/_dWbmyJr
I reduced the wire length to 20ft.. the output is still between 20 to 30watts.. I tried using a 24v battery as well as a 12v battery.. but will the battery matter?
I am Saikat from India . I need a Chinese wind turbine. But It not available in India. Please help me
Thank you for actually documenting the power output of the mill. I’ve seen a lot of these videos that doesn’t do that.
After reading a lot of bad reviews for this type of “China-mills”, I’m rather surprised this one can produce the wattages they claim it can do. however, I guess you are having a minor storm to get >400W? - but still it’ll all sums up. The "Ista Breeze i-1500" you recommend looks like a pretty good wind mill to go for.
Thanks for watching! Some of the chinese turbines can be pretty decent but it can be a real chore to find the goods ones from the bad. This particular little 400w turbine was a gem. I saw close to 1000w (peak) from it on a few occasions.
The iSta Breeze i1500 and i2000 turbines are easily the best watt/dollar ratios you can get right now.
Running wind turbines with no load can damage them. People who buy a cheapie (probably the first one they ever bought), take it outside and watch it spin around in their hands with nothing connected, so no wonder it doesn't work properly after that.
Also I saw a video where somebody mounted it in a tree, as in, among all the branches and leaves. They lived on the coast and had really strong wind, too. If they set up a few decent small turbines they could probably produce a lot.
Hi, What is the model number of the 700w? Thanks
Most of the generic Chinese turbines don't really have model numbers, you have to go by general looks. I'm pretty sure this is the same turbine: www.aliexpress.com/item/32865133395.html?spm=a2g0o.search0302.0.0.6f9f4573lRYBha&algo_pvid=f07f5212-9fa8-4985-bb6f-9155bc964777&algo_expid=f07f5212-9fa8-4985-bb6f-9155bc964777-4&btsid=0b0a555a16152581665286525ed868&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_
For the price, though, I strongly suggest you look at the iSta Breeze i1500 instead. It's only slightly more money and tremendously more performance. If you really want the 700, though, mine is for sale.
Hi , why my wind turbine wont spin on low wind speed ? Barely i can spin it with my hand is that normal ?? Thanks
Hi Alberto! It's going to be one of two things: There is a short in the output wiring causing the turbine to brake OR the battery bank or inverter or load you've connected the turbine to is too heavy for the turbine (battery voltage too low, inverter demand too high, something like that). What kind of turbine is it and what do you have it connected to?
Toys for Watts thanks !!its the same like your video it cost me $ 100 on ebay but i see only spin on very high speed wind not on low speed wind .
Can you post a link to the turbine you bought? What do you have it hooked up to? Mine does require a pretty hefty breeze to get it going. It makes very good power once the wind is up to 15mph or so, but it's not even going to start turning below 10mph.
I have a question. Can a Wind turbine still produce electricity even when the wires aren't hooked up?
That's a surprisingly complicated question! If there's a magnetic flux passing over the coils, they'll move electrons. Resistance is important here. The more resistance there is between the three phases, the faster the turbine will spin. The lower the resistance, the more drag on the turbine. In essence here if the leads aren't connected to anything then there's infinite resistance between the phases...you're still producing electricity but if it doesn't have anywhere to go then it doesn't go anywhere....and your turbine spins out of control.
@@ToysforWatts The reason why I asked is because I am into windmills and I would like to get one of these turbines but just have it spin like a regular windmill. Is there anyway I could disconnect the generator to have it do that?
@@randalnelson7094 🙆did you buy it or made it yourself?
Underground bunkers that want no solar or wind to attract people to you... you could take one of these turbines and hook it up to the back tire of a mounted bicycle and have your entire family take turns Pedaling.. allowing you to get daily excersize and power for your family. TEAM WORK! 🙂
The problem is that these altenators require around 3k RPMs to produce usable power. Unless gearing is used to speed up to the required RPM which will increase the load to the pedaler, a good work out!
That types of Windturbines where much better than vertikal axis turbines. Thanks for Upload. Best Regards from Germany.
Yes. This is the third one I've done and I consider it a success. Seller rated it at 400 watts at 12.5m/s and it exceeded that rating slightly, and significantly over in higher wind. I have another one rate for 500 watts that I consider a failure...it has never exceeded 280 watts in extreme wind...but it still manages to produce usable power...just not as much as the seller claimed.
I may try another vertical axis turbine in the future but that last one has diminished my interest. They way they're made I just don't see how they can put enough copper and magnet in them to make them perform decently.
when it says 400 watts, the 10% is the correct wattage. Just remove the end zero. That's the max==40 watts max. If 500 w rated, its 50 watts logically. That's my observation with wind turbines and some advertised solar chargers.
Not with this turbine, it performed very well and peaked nearly three times it's rated output. There's good cheap turbines out there, the problem is that finding them is a bit of a crapshoot because they all look identical.
I got something similar advertised as 800W. It produces 30W.
I saw somebody who bought a 100w solar panel, which was tiny and actually made 30w. I bought a couple of 30w ones to charge a small sogen, the ones I actually got are 10w. Even when I was expecting to be scammed I still got scammed! Had 8w reliably out of them in very-far-from-ideal conditions, though, so at least they produce!
I think my cheap chinese wind turbine needs a very strong wind
Or typhoon to spin the blades😂
So i decide to keep it and use my wind turbine
When there is a typhoon coming😂
if I had so much noise around my windmills, the neighbors would shoot me without a sentence.🤣
super
If you have rubber between your pole and metal brackets/wood, it'll cut down on noise.
Hi from istabreeze company. And I have one question. Can your test the heli 2 generator fron my company ?
Hello Erkan! I would love to discuss this with you. Please email me at makenzie71@gmail.com
@@ToysforWatts we will contact you my mail
@Erkan I am looking forward to it.
Just following up! I'm still very interested!
@@ToysforWatts just send mail
Did you use those long bolts for heat sinks.
I don't know which long bolts you are referring to...BUT there was no attempt made at additional heat dissipation. This little turbine has not really needed any kind of heat control even when it's being pushed really hard. I think it's a damn shame it's no longer available because it's one of the more solid models I've dealt with.
Toys for Watts the ones holding your wires that stick through the plywood.
Oh okay no that was just a quick, easy way to get tie in points where I could make all my connections. It was cheaper and more robust than terminal strips, a lot neater than wire nuts and crimps, and more convenient than soldering all the connections.
I have just got one myself and it is not turning.
That sucks, what kind of turbine is it? Tell me about the system...charge controller, batteries, wire, etc
Hi good day want to purchase a turbine is the ista breeze 500, 700w any good or the eBay 400 w is better can you please send me a link ty
I don't know about the smaller iSta Breeze models. This i1500 is so far the only iSta Breeze I'm played with. What's best is going to depend on what you're trying to do with it. What are you wanting to run with your turbine?
@@ToysforWatts ty its backup for my 24v solar can you recommend any of the smaller ebay ones
Link to but this one ?
This one unfortunately has not been available since I bought it. I would like to have a few more of them myself.
@@ToysforWatts can you recommend a good one that will start and run in low wind speed ?
Your cable runs should be made with thicker welding cable
I'll admit I would like them to be a bit heavier, and I'm sure they're costing me a little output, but every turbine so far has hit rated wattage with the exception of the iSta Breeze (10w shy) with the wire I'm using despite that possible loss. So, unless you're willing to pay for the wire, I'll probably continue to use the same wire. If I have to choose between reviewing another turbine or buying #6 wire...well, it's not much of a choice.
You need to change out the 12-2 your using and use a standard wire. You will see a major improvement in power output.
It already produces more than double the advertised rating...I don't think it could handle doing more :D
Plus the run for this one is only 20ft or so...if that...it should be more than adequate for what's going on here. My bigger turbines definitely need larger wire, but when I can afford wire or turbines choices must be made lol
Toys for Watts Ok but stranded wire is really what’s supposed to be put on instead of solid. Mark my word a good extension cord would give you better results. That’s why the 3 wires coming out of the turbine are stranded. Looks like a decent setup..
I love when they sell 9000,8000,6000... rated power turbines for 100-150$ and reality are around 200wat !! If I buy that I will ask half money back because of fake/wrong power rating!!after all who the fak will pay thousands of $ for (weaker) solar panels if you can get for 100$ turbine which can manage power for 2-3 houses/apartments
There seems to be 2 differing weights of them I wondered if is 2 types ? What power do they give 1kw may be ok but only a front bearing is Very weedy, a would take slip rings out and extend shaft to a rear bearingay . can get larger blades but is windings large enough for say2kw ?
This is a perfect example of who you should not be buying from regardless of getting it free of charge thats disgusting please be for the people not these scamming junk companies
Watts doesnt matter if ur batteries are charging fully reasonable with ur consumption, wattage is just the measure of volts over a period of time
This is why I’m so concerned about Chinese products. It’s about the buck, and not the quality.
Rubbish blade design, seriously CRAP 💥
