A reliable off grid system will have consist of wind, solar and petrol/diesel generator to guarantee year round production. It's a pity nobody is told this from the start. Living with both ready made and DIY wind turbines, our experience is that the wind turbines realistically function as a scavenging back up generator compared to solar production. Very informative video, I'll keep an eye out for any clips of our vids in your future productions 👍😎
Nice presentation. I have an off grid PV of 5kW that charge a battery cell made of 8 batteries. The system powers up a mountain cabin and sometimes during the winter i have to use a diesel generator to charge the batteries and power the cabin as in winter is less sun and less day light. I think that if i buy and install this turbine and also add 4 or 8 more batteries it will cover the needs and i would never use the dirty diesel generator again. So i will ask Jessica about the order. Thanks alot.
check out lifepo4 prices now. it's cheaper than lead acid now. prices starting at 40$ per 1kWh. so you can have rly sturdy power year round! good luck with your project
hi. at some point on your other channel you mentioned about your own setup on a house rooftop. I am really interested in seeing your exact live and realistic example. Can you please share? how exactly is it made? how much higher the turbine is lifted from the rooftop? how exactly the wires holding the mast are tied? well, basically anything about your exact setup. can you please create such a video? just shoot it with a phone, no need in awesome quality or fancy images - just live and realistic example. please please please?
I have two istabreeze i1500 turbines. Excellent machines. Up two years, no problems. The only other ones that look good are from Bayoung brand which look exactly like the one you show on this video. Are your turbines Bayoung? ....also thanks for BEST VIDEO ON youtube for small wind. Just subscribed!
thank you! as far as L2 turbines there are 3 factories but 50 brands for this type 😁. they are exceptional for power to price ratio and high voltage versions. since PV is very popular high voltage versions can operate with standard pv inverters. which decreases cost of whole system.
Hello. Great video as always! Can you tell me where is the calculator to calculate the wind energy on the mast? I am not sure my mast is ok. It is 4 meters tall (on the roof) 76mm in diameter, 3mm thick and the wind turbine is like the one you are showing in the video but 1KW only. 2.5m wind wheel. Thanks
Hello. These are great videos. Thank you for your insights. I would like to install that turbine on a hydraulic tilt tower ( 9 meters high, cylindric pipe, split in 3 segments) for home use. Based on your experience, can you please advice on what would be the most suitable dimensions of the pipe (e.g. diameter, thickness, the segments of the pipe should be conic or straight, etc.)? Thanks in advance for your support and looking forward to your future posts. Best regards.
Hi, great video! Is this still the best value for a domestic wind turbine generating between 1 and 2kW? We live in a very windy locatio on a Scottish island in the North Sea and are looking to install a turbine. Ideally with a battery.
So as far as I understand there's 2 ways to use wind turbines in combination with solar: 1. Have the wind turbine controller charge the same 48V batteries that the solar hybrid inverter is 2. Have some sort of wind turbine controller that can then be fed to the solar hybrid inverter solar panel input. In my opinion 2 is better because then you have just one charger of the batteries and you can inject the extra energy into the grid in a much easier way. The only thing which I didn't understand is where you can get the needed controller to link this turbine to the solar hybrid inverter and also how exactly you connect it. I suppose for some inverters that have 2 inputs you can use one of them for wind and one for the solar panels.
Thanks so much for this video, the pictures you have of the generator at time stamp 1:12 is the same generator I just mounted on a 14 meter pole in NZ. Its 1500 watts, 48 volts. Do you know why the tail swings off to the side as soon as the wind starts to blow and then slows down and swings around away from the wind? I haven't hooked it up to the charge controller or the battery bank yet, will that make a difference? Thanks🙂
there is 1400 blade version 1,5kW. is your tail is pointing a little bit down? if yes this is possible it is mounted backwards. tail suppose to turn whole turbine at 50mph out of wind. maybe now if it's working without load it behaves strangely but it is possible you need to rearrange tail
Thanks 4nrgy Tech for the info, I'll have a closer look at the tail position, maybe it can be mounted differently but it looks exactly like the one you have pictured in the video at 1:13 and the tail swings off just like the picture. Maybe that's the way its suppose to work>👍Thanks again @@4nrgyTech
Very interested to hear that you can send rectified output from the wind turbine to a PWM solar controller. I had thought of doing this but didnt expect it to be successul so I didnt go down that route. Because, with solar panels, the PWM controller will stop charging and effectively "block" the solar panels, by taking the PWM duty cycle towards 0% when the battery voltage limit is reached. But when taking power from the wind turbine, the excess power must be dumped from the battery bank using a suitable voltage sensor, high current relay and resistor/heater load. ( otherwise the turbine would blow up the controller/battery bank ?? ). From looking at small wind power technology over the last few years it seems that most small wind turbine users take rectified ouput directly to their battery bank and then use off the shelf products such as the Tristar TS45/TS60 in diversion mode to get rid of excess power ( I've made my own solid state relay system which does a similar job ). But I am intrigued at the idea of taking the output straight into a PWM controller. Would really like to see some sort of diagram to see how you get this to work. You mentioned in some comments that you can attach a dump load to the solar controller load terminals...but would'nt that just drain down the batteries ? Thanks for a great youtube channel!!!
check solar controller manual for output load : in all of them you have turn on voltage and turn off voltage. you put turn on 15.5v*how many batteries you have in serial turn off 15.4V and you good to go. Its not that complicated and works
@4nrgyTech Okay.. I understand now. You just interpret the "turn load on/off" parameters to mean start/stop dumping. That should work well. I must have looked at 100s maybe 000s of posts on TH-cam and green forums and no one else has suggested this idea. Sometimes the simple best solutions are in plain sight! . Maybe you'll do a video on this in the future?. Probably a superior method of control compared to simple dumping through a basic volt sensing relay which is what nearly everyone else including me , seems to be doing at present. Only concern is that the controller load on/off relay needs to be solid state to survive long term frequent operation. Maybe need to divert the coil signal to operate a high current SSR instead.
it is always mosfet transistor for connecting disconnecting. same as in ev motor controllers these can stand millions of connection/disconnection cycles so there is no big problem. only thing is inductive loads they can cause voltage peaks while disconnecting but we are talking about low voltages here
@@4nrgyTech You are extremely knowledgeable in this subject and should put out some training setup illustrations, I know what you speak of, but not sure where to put the bridge rectifier. I don't subscribe to many channels, but I'm subscribing to yours. Thank you for the info, it was very helpful.
great video. i want one. but first i have two i bought from china for $500 aud each. they are 500w 48v ac. but i cant find a decent priced and good quality controller for this. im off grid on a sail boat with 20kw/hr of lifepo4 to charge. i jhave 800w of solar but this only gives me 4 to 5 kw/hrs a day in sunny conditions. i want to double that and winter proof my charging. can you do a video on charge controllers pelase for my 48v battery bank. thanks
first check real voltage of your turbines. disconnect load and controller and measure AC on average wind. you need at least 50V(AC between any of three wires) then connect rectifier and simple solar 48V controller.
it's ft2000. for offgrid I would use 48V version with cheapest solar charge controller, chinese 48V hybrid inverter and forklift battery. if you do not want to spend too much on battery use 4pcs car batteries. same Ah best if same brand.
*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. *With solar modules, on the other hand, you can reliably generate green electricity for 25 years at approx. 3-10 cent/kWh!
if you can't this is true: you can't. it is not that this is impossible. it's just you can't. go windy com put your address and check wind at any hight you want. I have first hand experience of situations where production was higher than 1MWh fron each 1kW of installed turbine power. so sorry but it's just your opinion.
