- Ive watched them drop from over $1000nz to $299nz in 10 years, with definite improvements in design and quality. This particular model is now Series 3. all the defects that I knew of from the last decade are fixed.
*The plastic prop hub is now cast alloy. blade attachment has improved
*The twin bearings that flogged out the housing are now replaced with one larger double race bearing.
*The Brushes and slip rings now far larger and thus should not get too hot.
*General quality of the alternator, fittings and blades are also vastly improved over earlier and far more expensive examples.

I purchased this one for $299nz us$160. from another company that is not currently listing them- www.trademe.co...
In up coming videos I'll improve the moisture sealing, paint finish durability and brushes will be improved before I mount it and test it for a week or so before starting upgrade mods in future videos.
Very informative video. Thank you! All the best from. Dublin City. Republic of Ireland.
The brand new wind generator looks very nice. Thank you for sharing
Great video! I just pulled the trigger on a 400 watt 24 volt unit to supplement my 800 watt solar array. We have no shortage of wind here in the Adirondack mountains of NY (US). Guess we'll see how long it holds up, $200 amazon special.
That is awesome! great price. just keep an ear out for a howly chinese bearing and change it before it self destructs
Supposedly it has a extra wide bearing for improved longevity but I'll keep an eye on it
@@chad2886 how is your turbine doing?
I got the 24 volts, 600 watts model. I already had 1600 watts of solar panels. I've had it since March 7 th. I only have it 16 feet high because there's a lot of lightning ⚡ here. My battery bank is made from twenty big marine batteries from Autozone. There was an 87 mph wind storm in May, and it survived. I used grade 8 bolts instead of the ones they sent. It was making over a thousand watts for about twenty minutes until the wind let up. It's made similar to yours but the part with the bearing is thicker. I put some Armor All spray on the blades, (3) , and the crack where it's put together. I used a 1 1/2 ID pipe that's fastened to a piece of angle iron that's lag bolted to the barn. There's only five feet of it past the ridge of the barn. I made the base with a three foot piece of bigger pipe protruding from the concrete so that I can raise the pole another three feet if I wanted to. It would get cleaner air, but probably hit by lightning ⚡. I live on the side of a hill not too far from the top. So I have it chained to the base at the moment. It is almost 7 a.m., the battery bank is showing 25.1 volts, things will be charging again in a few minutes. Full charge is 25.6. The batteries are pretty much charged by ten a.m. usually. I have my wind generator hooked up to the battery bank with a 250 amp rectifier. It works pretty well that way. It can't make enough to overcharge them, enough to damage anything, I just turn something on like the hotplate if the voltage gets a little bit too high. I paid $433 for the wind generator. It's holding up okay so far. It was funny when I got it. I had already ordered it, and my uncle came to check out my power system. He said, well you've got a pretty good system, except you need a windmill. About two days later it shows up. I wish I could have taken a picture of his face. It was pretty funny.
That's a great write up! All done in a shoe string budget. Like things should be 😁 mine is 24feet high. But in the shadow of my big Oak tree. Over winter when the leaves are off the tree, it belts out the power. Often charging at 10-12 amps. I need to get an update video done
It works better without controller, use 3phase bridge rectifier only.
Yea the weather is bad Im off grid on solar and winter is a bad time for me
have to start the genny with the price of gas wow
cant wait for next vid
I just pulled mine down. No more for me I was loosing power with the turbine. As soon as I disconnected power to it. The power went up . When there’s no sun for solar I use battery charger to boost power on very dull days. Espialy overnight.
Great video...now Im hoping I can duplucate what you do by studying the video! I dont have an electrical background. Hopefully my common sense will prevail😁 Very dry at my home in central PA. Conserving water....we could use some of your extra rain please.
WOW! When you pulled the rotor out the Magnets are sooo tiny! No wonder these cannot achieve much power... Also the wire windings are ultra thin, Loose and short. Yeah I'm gonna stick to building my own.
Very good, thanks!
Would recommend you use a top over video stand looking down on the item you're demonstrating so the back of your head doesn't keep covering up what you're trying to display. Otherwise, very helpful video!
Thanks for the tip!
If you look at the various turbines you will actually see that the only thing different between the 300w and the 600w is the sweep of the blades.
Now that's interesting
@@t.h.o.r. BTW? Despite your opinion, Child labor is outlawed in China today. And they have the fastest growing middle class in history because wages have tripled over the last 12 years.
Oh thats awesome - There are two channels that I watch for China news Serpentenza and ADV China- neither of them have mentioned a rising middle class. I remember 30 years ago--when China was making satellites and cell phones but for some reason when you bought an 8mm tap and die it was 8.47mm@@davefroman4700
Interesting I'm thinking of doing the same but using a solar controller with a 3 phase diode with heat sink to see if it fixes surging there's many ways very good.
Yes- I really doubt that these controllers are true MPPT. My current home made turbine uses a bridge rectifier and a PWM solar controller. Its worked faultlessly for 10 years on a micro(60 watt) turbine. The low speed assist feature will be one thing that Im testing. My old DIY turbine has a mechanical system that allows 355 degrees of run up rotation before the drive connects and it starts turning the alternator.
@@t.h.o.r. Nice that sounds the go I've got rid of all 240 volt appliances and gone 12 volt everything and try not to run a power inverter I have a small set up using AGM batteries for now have you used lithium batteries on your set up I've heard the lithium ion batteries are not very stable lithium phosphate one's but I haven't ran low on power for a while the wind blows very hard where I am it's like a waste not using it have you ever taken apart a bigger chines wind generator I was looking at the 8000 watt one but if it's only the magnets that change it might be worth trying what you are doing.
@Trypanosoma Cruzi=Myocarditis. I saw the 600w and the magnets were twice as thick. So Im just going to add magnets in two stages with output tests in between.
Thank you for the information,these turbines have gotten so inexpensive that I (oops) bought three. Project moving forward B.
Awesome Bruce- mine's going so well. I modified it adding extra magnets and it pulled 4 amps in the big 30mph winds today. Best unmodified amps was 2 amps but that was in 20mph winds. its now 1030 pm and its still cranking out power. I must get more batteries to fill up :)
At what voltage level & which mppt did you used also the braking mechanism ??@@t.h.o.r.
Are you planning on mounting the rectifier on the pole and sending down 2 wires (- +)? Or, are you planning on sending down the 3 wires 3 phase AC, placing the rectifier where the battery is?
Thee phase down the pole - all the gubbinses are in the battery box
Some funny sound/video alignment issues going on there, but otherwise very interesting.
I'm on grid and urban, but have always wanted a turbine to supplement my solar generation at night and wet winter days.
My 60watt home made one is all Ive been running off for the last 4 days. Filthy weather here.
Re the sound- I tried speeding up the vid by 20% to make it snappier- the sync was thrown out and I tried fixing it segment by segment- then lost interest when it jumbled its self up again!
Instead of gluing magnets on, why not just go to a machine shop and have them machine you a new rotor? You can have them design the magnet holder gaps exactly the way you want. I believe this will work a lot better.
In an airline pilot's world maybe- But the focus of my channel is doing great things without spending money. have a look at some of the other thing that Ive achieved without paying other people
Those would be great to have. I wonder if it could be made from a truck’s alternator
Is there any update to this wind turbine output
Would love to see a ELI5 on build your own super capacitor bank. You say there is a separate video showing how it was made, but a search for 'capacitor' doesnt return it :(
Coming soon!
Video is up now!
Bet this got a workout last night
Its not going up till the weather gets nicer- we had way more rain than wind here. slips and flooding in all the usual places....
Good video. I want to improve my supply and think Wind might be the answer. I am on 48 volt system and looking for a 48 turbine. Do you have a recommendation? Thanks.
Sorry Russell Ive not looked at commercial 48v turbines.
But Im in the same position as you- The weather has decimated my panels output and Im relying on this one small generator. coming soon Ill be building a ducted VAWT for the edge of an exposed shed. Ive spun up a treadmill motor to 300rpm and im getting 90vdc= Ill put that through a MPPT controller and . should get a good 6 amps
It will be interesting to see how well it performs before and after your modifications? I went to watch your capacitor battery video and I couldn't find it. So I'd appreciate it if you could please supply a link or video name so that I can check it out.
haha- thats the one Inm working on right now- check back tomorrow
In the last 8 months they have progressed by extreme leaps and bounds.
Tell us- what is new?
Any thoughts on 3 vs 5 blades on these types of wind turbines?
Yes Morris- for low wind areas = my old 7 blade performed better in behind my trees than this new 5 blade.3 bladers seem to work well on marine or coastal applications. they spin faster but make more noise. - I never hear mine unless its ridiculously windy
@@t.h.o.r. Thanks for your input. Your videos are excellent and are helping me make informed decisions on small wind generator options. There is lots of wind where I’m living but can be gusty at times. I just need a little boost to the battery to help my solar panel in a small off grid setup.
where can I get one of those?
They are all over Trade Me, Amazon, Ebay and Ali express from about $199 upwards
$299.00 Zealand dollar is about $3.50 AUD, LOL sorry
😆😉🍻🍻
@@t.h.o.r.sorry mate. I got Maori friends, I don't know if they find it funny or just humour me.
@@t.h.o.r. U should know that know funny we have between us.
How noisy are they? this causes problems for urban installations, (where most people live).
This one only makes a noise that can hear inside a few times in the last year. a surge of Pfffffffft when the wind really gets going. Its just as it accelerates. In constant wind you dont hear it.
Magnets are the same as my so called 1000 8 blade wind turbine absolute junk waste of time and money
thats so true watts and kg and psi work difirent in china as here in cape town...not a saporter of china
400 Watts in 85 mph of winds
hahahaha- thats pretty much what Im expecting- But I like to play. Wait until Ive hot rodded it! You will see the smoke from your house!
where did you buy that from?
On Trade Me www.trademe.co.nz/a/search?member_listing=5033878&bof=9zEosvTr
dont buy those 400 watt vawts 0 power wont spin fast enough to charge took it apart found the prouble they only got little 1/2 '' button magnets in them now with that tiny alternator . i short tested the three wires toghter to test for cogging strenth you can easely spin the shaft with your fingers there should be some cogging but doesnt seem to have any no amps with a amp meter comming off the rectafier either couldnt even get it to do 6 volts spinning by hand it was the 12-24volt machine i wanted 24volt not even close didnt waist my time installing it it went to the dump because i would never sell this to someone else . so i would differ they just got worst .
Yup _ I totally agree. Thats why in the next video I double the magnets and get 8amps out of it! czcams.com/video/eJWGosce6m0/video.html
about 5-6 years ago i bought the china 700 watt hawt modle it came with the 36'' 3 fiber plastic blades that one would only get 3 amps at 24v not very good untill i made a 5 alluminum blades to fit a 5 blade hub i bought a 3 foot sheet mattel roller i made each blade from 1/8'' thick x 9'' wide x 32'' long i clamped all the blades toghter after i cut them to size . i ground them all toghter at the same time so they would come out exactly the same size than i rolled them the base or root had a 2.5'' or 3'' lift cant quite remember and the tips had a small angle from being narrow 2.5'' wide the next wind storm i got 20 plus amps out of that one because that allternator at the time had a strong cogging so the alluminum 5 blades did the trick it has been working good since dont know why i wanted to waist my time with a vawt but they did look good in the add and vidoes . so about 5 years ago they made the magnets a little to strong for the 3 plastic blades thats why it would stall out when it reached charging voltage the 5 homemade blades made a world of difference but i did also had to made the tail bigger aluminum again 1/8'' thick . even with the bigger blades the electronic break a 220 30 amp twist plug and outlet and a dummy plug wires all shorted toghter for stopping it it still able to stop the blades but any bigger it woudnt so its peaked out at 20+ amps at storms .
