Hey, i already built it, but after a few months the blades are wiggeling and I tried to unscrew some stuff but it didn't work, and i'm scared that sometime the blades will just fall off while it's spinning very fast or smth like that

Basura con alas 😂

From where i will get low rpm turbine for home use all these data showns Wind Turbines are useless

Gud work

Another china fake..😂

It looked like your simulated wind speed was only 8 mph. The one thing I've learned about wind generators is the biggest challenge especially for home built ones is keeping them together in high winds. They have a tendency to self destruct but also to perform well they do need to be mounted up as high as possible to be in the wind without obstruction. IF not you will achieve low performance no matter how well built.

Thanks for showing this video. I've been a solar enthusiast for years and just recently started getting into wind turbines for my RV. Vevor is selling a 500-watt model on clearance for only $91 so they are not probably selling well. I already know wind doesn't produce much power but just wanted something to augment the system at nighttime. $91 is a cheap way to enter this interesting field.

Son iguales,es un falso mppt

Creative video, keep it up, thanks :)

senza batterie?

chinese are submitted to jews communist liars

LOOK ON THE SMALL SURFACE OF THE ROTOR. THIS IS WHERE THE FORCE OF THE SYSTEM IS GENERATED. IT IS A FAKE.

It must have the 6-diode bridge rectifier built in. The stator looks like a 3-phase wind, but, only two lead wires. Reading the voltage on the meter in DC suggests, the rectifier is built into the alternator. The best way to use this turbine, is with a pulse width modulator, that can load the alternator proportionate to voltage, emulating a pure resistance. The maximum current needs to be limited to 5% of the short circuit current, to allow the voltage to continually increase proportionately to rotor speed. The maximum current available is limited by the field strength of the magnets/stator impedance. The fact that it can produce high voltage at very low RPM means that the current is very limited. Connecting this straight to a battery would limit the current available, and create a minimum wind speed necessary to develop charging current. that current is greatly limited, because of magnetic field strength. A pulse width modulator can allow the voltage to rise, by reducing its duty cycle. That extra voltage times the current becomes wattage, which greatly increases amperage available to charge the battery, no matter what voltage the battery is. Since the maximum output of the alternator is the same, no matter what the battery voltage is, the wattage available from connecting the turbine direct, is exactly proportionate to battery voltage. The current (above a certain wind speed) is exactly the same. Without an electronic controller, don't look for more than~30 watts into a 12 volt battery, or 60 watts into a 24 volt battery.(roughly 1/10 its rated power!)

ราคาเท่าไรรึคับอาจารเอ่ย😮😢😂

Do I have to connect all 3 wires??

Can I use 12 gauge wire to connect the turbine?

I have one of these exact controllers all wired up right just like your vide, but i get flashing error and no charging light + it dont show indicatord from spinning turbine to battery and from battery to load, though i have no load as i have 110amp fuse switch to inverter from battery bank. Running bank of 20 12v 60A cells Is my device defective have i missed something ?

Rated at 400W and produces 100W 🤣🤣🤣🤣🤣

WICHTIG - DAMIT ES LÄUFT (über 100 WATT): ich habe frisch mir 2 stück gekauft von den 5 flügel turbinen ... WICHTIG: 1. der aufstellort ! im garten der läuft selten weil dort wenig wind ist - anders als ich dachte ! vorm haus an der terasse wo ich den anderen nur provisorisch befestigt hatte - der rent wie sau ;) UND ABER ich hatte nen langes kabel ca. 1,5mm2 .. hinter dem wind laderegler ein step up modul und dahinter einen 0815 solar laderegler - macht für mich mehr sinn - UND ABER es kamen bei starkem wind 13-16kmh meist 20 volt aber nur 0,1 bis 1,2 ampere ?! WEIL logisch ... kabel viel zu lang ! bzw. querschnitt viel zu klein ! UND VOR ALLEM diese angebliche BREMSE ?! da steht "unload" ? ob das wirklich eine BREMSE ist ? ;) WEIL ich hatte dann mal DEN AKKU vom SOLAR REGLER runtergenommen UND zack 20 VOLT mit 7 AMPERE !! ALSO nochmal SIEBEN AMPERE mit 20 volt = 140 WATT ;) (bei amazon hatte sich wer beschwert weil NUR 280 watt rauskamen ^^ und nen ingenieur meinte auf englisch die meisten haben die geräte falsch zusammengebaut ^^) ALSO: ich nehme stark an - es ist KEINE BREMSE sondern "überlastungschutz" mit akku gehen nur x ampere rein ! der rest wird "unload" also abgeriegelt ?! und dann müsste man auch MIT LAST TESTEN ! bei z.b. den MPPT solar ladereglern kommt erst richtig leistung UNTER LAST ! beispiel: akku voll oder fast voll und laut laderegler kommen nur 5 watt rein ... weil akku voll und keine last - sobald ich last draufhänge geht der laderegler auch hoch ;) also: KABEL kürzer oder dicker ! optimal: phasenumwandler OHNE wind laderegler ! dazu: step up modul (mind. 10 ampere) und DANN das WATTMETER und dahinter LAST ! nur so kann man "wirklich" testen .. die akkus alleine haben ja schon "begrenzte" ladeströme ... und wie gesagt: OHNE AKKU am solar laderegler kamen bei mir "locker" 140 watt also 20 volt hochgeregelt über das step up modul und dazu diese 7 ampere ... so berichten auch andere leute bei denen die räder laufen - sobald das "gleichstrom" kabel (wechselstrom hat nicht so hohe verluste; die 3 phasen direkt vom windrad !) zu lang ist oder zu dünn, wird es "nichts werden" !!! den fehler hab auch ich gemacht obwohl ich ex elektriker bin etc. pp und es besser wissen müsste .. ps: auf ebay kleinanzeigen unter dem suchbegriff "PTC SOLAR HEIZUNG" hab ich nen experiment eingestellt .. dort kann man gut anzeigen schalten für ERFAHRUNGSAUSTAUSCH !!! einfach mal schauen oder selbst solche anzeigen dort erstellen .. LOHNT SICH !!! man findet gute kontakte und hilfreiche tipps ;)

Which if any of these brands are trustworthy?

Don't buy this or similar like these . All of them made from China, junk.

How is a wind turbine rated for 600 watts going to supply 50 amps ( 600w / 12v = 50a ) down cable rated to 10 amps?

I'm curious - have you try to measure RPM and check power at higher wind speeds as 7-12 m/s? (I was trying very roughly estimate power of this turbine, but with area ~0.3m² I suppose we can't expect more than ~35W range at 10 m/s).

I did gear it 1.4 to1 and seen 4 + amps at 9-11 mph wind. (4-5 m/s.) Put 3 bigger and litter longer blades on it.

Hi just found your videos and will follow Would you recommend this turbine or do you have a recommendation for a small house west of Ireland, thanks 🙏

Larger blades geared to the rpm you need works ever time. Still have to have a braking system. Larger blades more torque for the wind you have. You need 600 rpm at the generator. Want 200 rpm max at blades then gear it to 3.1. The blades will have to be made just for this. You have to match blades to the generator for the wind you have.

Youre doing God's work! Very educational

Another annoying video with horrible music. Come on.

Gracias de nuevo amigo 😊 llegué a dudar con esos aerogeneradores se veían bonitos y parecian eficientes😢

400 Watt 🤔🤔🤔🤔 zeigt und beweist das mit !

Spec plate: 18 m/s wind speed !!! If about 800mm dia at 18 m/s and TSR = 1 that's about 400 RPM. At triple tested RPM it MAY do better. Which would be TSR of about 1200-1500 RPM. AND 18 m/s !!! :-(

Do you really expect honesty and integrity from a Chinese company???????????

It is obvious his is three phase so why only one voltage, one current and what sort of load is he using????

I just got one of these as a test. So far build quality is absolute trash. Can't wait to see how it goes. I'm looking into wind to trickle charge my batteries when I don't have good sun. I wonder if this will even do that.😅

m/s is meaningless, and very confusing.. would be nice to see units that are easily regognozable

Try a motor from a air heat-pump. Your will get dc power both ways and also good voltage and amps.

Vevor contacted me for a review of that 500W wind turbine, luckily you had already tested it so I didn't have to consume my time for that, thanks!

The main problem is all the dishonest sellers from china that operate on ebay/aliexpress/ e.c.t when you find the poducer of these turbines (only on alibaba) you will se watt ratings that are withinn the realm of possibillity like small turbines 12v 100-250w (one have to be carefull there also as other companys will buy the housings blades and set turbines up with very thin wire and tiny magnets,, and they will only produce 30watt ) but there is good turbines to be has for a decent prize, but if you want to have power you got to have size (unless its only to kaap batteries charged not producing for use), i would say no smaller than a swept area of 2,2 diameters and the pma will be heavy over 10kg usually about 20kg ,these turbines is also sold on the other sites for 5x or even 10x the amount the turbine cost from the producer a 1000w 24V turbine will cost about 300 bucks not including shipping or chargecontroller, there is another brand from turkey also istabreeze , they have a very good pma but there is a limitation on the blades for example a 1500w 24V model 2,3 diameter 1600watt max power they will produce about 600-1000w mainly due to blade limitations ,and they are known for water intrution in the housing (easy to fix )but it is still a market where you got to do a good amount of research or get burned ,it is not like solat arrays unfortunately where it is very predictable the amount of power to be had,,,

Buy from Missouri wind and solar cheap , modified car generator . i bought one back in 2010 but they still sell kits and generators ++++

It makes me so angry that those chinese companies keep selling that rubbish! Generators are not low rpm (that's why they are so cheap) and power claims break all physics laws starting with betz law. Vertical axis wind turbines do work but people are prone to think they don't because of all these scam factories. I can name at least three companies that do work : Greef (China), Ecorote (Poland) and Suneo (Colombia). Also it is very important that output voltage matches generator/inverter input voltage in order to get advantage of the full power range curve. I'm sorry to say that but You are going to lose your time installing it, it won't make a single watt unless you´re under a tornado and it will probably break down if that happens. Readers be aware of scams like this one, lantern type, tesup VAWTs and any other offering more than 300W out of a turbine with a swept area below 1 square meter.

yep i really do not understand why people keep buying these vertical turbines , in order for them to work at all they would need a magnet ring the size of a bike wheel due to their low RPM ,i do not even believe a size like this would work with a gearing , and that pma looks like a industrial ceiling fanhousing,, i know of a factory outlet in china that sells decent turbines ,1000watt for about 300 dollars 2,3 meter diameter swept area it would be cool if you tested one of their turbines

If you have 2 wind turbine can you run both off the controller or do they have to be separate?

*All practical tests show that small wind turbines hardly generate any electricity! And only at very high costs!* Because there is hardly any wind close to the ground. It is also extremely gusty, which usually shortens the service life. Only if you need to be self-sufficient from the power grid, you should buy a small wind turbine for the winter. *With solar modules, on the other hand, you can reliably generate green electricity for 25 years at approx. 3-10 cent/kWh!*

You need a resistor to measure power, the low power showed by meter is the power absorbed of the meter itself!! Use a 50W 10 ohm ( banally a 12v car headlamp) resistitor and retry test

question I bought a 650 what turrbine problem with con troller id pumps 22 volts in a 12 volt system homw do i regulate it

😮Expectante ❤❤❤😊
