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 🤔😂

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.

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.

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 😑

I have had good success with the ISTABreeze 2kw turbine, seems to be rated correctly!

the "windsafe" 2wk istabreeze would be even better.

Thank you!

Thanks! Glad it helped your buying decision! I went with an istabreeze which was miles better.

​@@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.

@BMW R1200GS Adventure leave it there crap. Better ones rutland 504 very reliable airx wind also good.

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

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!

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

@@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?

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 !

we checked at 1000RPM, which was already too low.

Very interesting. A little like rating a speaker at PMPO rather than RMS.

Sorry. I thought you were testing the inverter.

No, I havent needed to, just change the dump load for something better like a 110v 3kw immersion heater

I was also thinking that maybe varying the power curve in the inverter could make a difference? But not 100% sure I know enough about this yet.

nope - only needed if you want to cap the export to grid - its not worth it for my set up

yep i went to an istabreeze with much better success!

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

is a 15kw motor but variable controlled. You need both volts and amps for power, both go hand in hand.

@@williamwofford4919 you can have high amps and low voltage or high voltage and low amps or an even amount of each or a variable amount of each

@@grahamflowers correct

@@williamwofford4919 15 kw is s 20 hp motor a bit over the top

@@grahamflowers not for alternator testing - we made some very high power stuff. plus we need power at lower rpms

Istabreeze are good! :D

Yes Chinese crap but people want cheap shit then get stung

that depends on the circumference of your wheel, for each revolution you travel the circumference in linear distance

also you need to divide RPM by 60 to get revs per second first

Yep its pretty pants. probably ok for near shore or remote islands ect but solar wins every time.

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
