Excellent information. Thanks. To make things better it would be nice to have some of the model numbers and their corresponding sources (you have 1 listed). You could even set up an Amazon store - I'd buy through your store.
I have yet to see one of these make significant power, at best the value of one solar panel. I understand this would be working in the middle of a windy night, but I feel we'd need a shitload of them to really benefit.
Great video mate You do excellent explanations Also these pictures looks exactly like the two I bought for 500aud each. (300usd) roughly Just gotta check if they are round tail or rectangle. See if I got ripped off or not Also as you suggested, I need to run them on a drill and measure the output voltage is 48v as in told they are
Great info as always. I was looking at Chinese wind turbines and was just ovewhelmed with the number and options. So many also had negative comments about being bad. It would really help if you could present some schematics about how to wire these up to a solar mppt hybrid inverter and also some links to some Alibaba sellers. Alternatively some specs written down so that we can track the wind turbines ourselves. Looking forward to your next videos.
I can’t believe you don’t have more viewers. I’ve learnt a lot from you this afternoon. Thank you. Will this and the previous 3.2 metre wing span work with my system that is tied to the grid. I sell the my power at rip off rates:) IE can I sell them any power generated by these turbines? Many thanks
if you have solar inverter you can use controller to cheat mppt into "thinking" it's pv panel. deming is making this kind of controllers but they are quite expensive. we are producing them too but now quantities are so small it's only for our systems. in April we are starting production in China so this should be cheap and widely available. I asked many chinese companies for this product but it comes to our production at the end. Strange since concept is rather simple🤷♂️ an we are making them in Poland for 15yrs.
Hello. Another great video. It´s easy to see that you know your stuff. Could you make a video about wind charge controllers? Looks like lots of people in your channel are interested in, including me. I think that the expensive ones are usefull to charge batteries. They come with boost and buck, mppt, mct, internal circuit brakers, manual brake, very good dump loads, wind turbine rpm control, adjustable battery setting, wind turbine power curve track etc Thanks
Another great video. I find this really interesting. I must have looked at hundred of articles and videos on this subject and I haven't found a single instance where anyone is taking turbine rectified output directly into a PWM solar controller so I'm intrigued to see this work for real. ( hybrid controller maybe, but not yet basic PWM controllers ). Connecting the rectified output to a PWM solar controller is an interesting approach. Most nominally 48v turbines create output voltages in the range of 0-200v. So I wonder how the average PWM solar controller ( e.g. EcoWorthy/Victron ) deals with such a high input voltage approaching 200v? when it typically receives 25 to 36v from panels ? Also, the PWM controller will reduce it's PWM duty cycle towards zero as the battery bank becomes full which would gradually unload the turbine causing excessive RPM andd over-voltage so there would have to be a "loading system" running in parallel such that when the battery bank becomes full the turbine is automatically loaded with suitable resistors. You mentioned before that the parameters on a typical PWM solar controller for connect/disconnect voltage limits could be used to achieve this and that this is simple, however it would be good to see a live working example of this scheme in action.
victron is no good. its too restrictive and brakes turbine. 48V wind turbine shouldn't go higher than 100V. also many controllers has 80V input restriction. if you have dump load connected to solar controller it is not a problem. unless dump load is water heater and is disconnected by thermal regulator in boiler🤷♂️
@@nhikoid To be honest, I am still looking. I checked this channel just to find more details on an inline DC solution using rectifier to feed into my spare MPPT port on the inverter. But given that you - apparently - need another PWM controller, and that this DIY solution is untested and lacks a dumpload, I am now back to what is easiest: AC coupling. But mind you: this cannot be used in pure off-grid situation, because AC coupling is done on grid-side (before the meter). So if there is no grid, then there is no AC to send the WT power to the solar inverter. In most western countries that's not a problem because grid is always there. The main advantage of this is simplicity, plus you can use off-the-shelve WT controllers. From what I can gather the VESDAS 2000W controller seem to satisfy lots of people. You can get them from AliExpress for around €400 including the dumpload. I am leaning to this one right now.
@@BeertjeRulezI wonder...could the WT rectified output just go directly to a battery bank shared with an ac coupled inverter charger like the Sofar ME3000sp. Then in the event if the grid going down, a feed from the batteries could go to a cheap non grid tied inverter to to feed a separate circuit of "green" sockets. Just so interesting. If funds allowed, it be fun experimenting!
Good video thanks. How can I add a small wind turbine to my current solar system as a (fake solar input)? I have two MPPT Solis 4.6KW inverters with two different input lines from panels.
Can you please provide some links to sellers of these NOT FAKE RIP OFFS of turbines, and also some hybrid inverters that can divert power to loads on voltage setting?
Hi thanks for this very informative video. I want to get a wind turbine for my home with nothing less than 3kw/hr preferably 4kw/hr. The lowest wind speed average for where I live is 6mph and average 7.9mph. What can you please recommend ? I have a 30kwh LFP backup. My hourly home consumption is about 3kwh without water heaters.
Firstly, I want to thank you for the TESUP video because I was thinking about buying 2 of them. Secondly, I have 16 solar panels on my roof and would like a little wind support. Obviously in winter there isn’t a lot of energy produced by the solar panels. I am thinking of 2 wind turbines. What would you recommend to support my solar and is there anything I need to be aware when I connect the wind turbines to the already set up solar network?
Any questions in comments welcome?!?!?! How can I find details about torque and voltage at different winspeeds for these generators If I am desinging blades to be used with them? Do you have any information on RMP, voltage, and torque you could share at 3, 6, 9, 12m/s? I am eager for tons of data if you have, or if you know from experience.
Hi have you tried paralleling many wind turbines together? . using cheap orange wind turbine controller, dc out ...... into a bus bar (because they have a diodes) ? 40A /48v . ? so logic turbines are 600w / 48v = 12.5 A each x 4 = 50 A at the bus bar... (or 3 to be under 40 A)

I would buy real 2kw(3.2m diameter) 48V turbine and connect it through rectifier and cheap 48V PWM controller directly to battery. its cheapest and safest way
Hi. Very good explained to me. I would like a little support for my computers which is running 24/7.

*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 a wind turbine as large as possible on a high tower 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!*
