Off Grid 2 KW Axial Flux Wind Turbine And MPPT Dump Load Controler Build
Вставка
- Опубліковано 5 лис 2022
- For the last 6 months on and off I have been building a new wind turbine. My old one was not design for the voltages I run and was made with limited tools and knowledge. now I have a workshop and a much better understanding of wind power I built a new one. it turned out exactly as planned and is working great. once I get some stronger winds I will do an update video of the output.
Thanks to wind power and more for the idea for the controller. you can find his channel here
/ @windpowerandmore6310
The idea for the controller came from another UA-cam channel. The clip I had crediting the channel had bad sound and got cut out. But visit wind power and more to see other versions of this controller and some great content. ua-cam.com/channels/pHl5wAaAYKhWvkDHaRXjlA.html
Make a set of blades man you can make them lightweight out of stainless steel, and instead of having the excess go into the dump wasted, can't you have like a fridge freezer instead ie fridge freezer gets powered by ordinary set up then once ordinary set up cuts out due to overpowering and switched to dump can't the power going into the dump power the fridge instead until things go back to normal so nothing is being wasted etc ? Man if that was me I'd experiment so much I'd probably blow the lot etc I Just can't stop but it's the only way you learn but anyway back to the fridge being powered by the dump after it takes over seems good no? And get those blades made man seriously for the wind turbine I know you can make a banging set of blades ? Try 5 ? Smaller but just as potent etc then the pole won't be taking as much flack, anyway brilliant job and I tell you what once I go electric VERY SOON you'll be making my stator and turbine and blades AND fitting it all too seriously your only A 2 to 3 hour drive from me so all good I'll give you the sizes they have to be and you work your magic with NO TIME RESTRAINT at all plus I'll pay you up front if need be 50/50 anyway apart from my rant good job brilliant stuff and I hope we meet one day so I can have a go at you about something the only thing your good with ? so take care of em mate seriously I know we're not fairies but mate ? take care of em as YOU DO everything else ok 🤗

I have had great success using Polyethylene (PE) on anything I do not want to be bonded with epoxy. One of the cheapest is plastic packing tape, it must have the marking PE on it, if it does it will work. Just tape the surface and the epoxy won't stick.
Because the wind is gusting from different directions did you consider a vertical wind turbine?
What ever project your working on is interesting to me . I’m impressed
Have to say Kris, as an electrical engineer myself your work is very impressive. Nice job!
I agree. Also an electrical engineer and I'm quite impressed how he builds everything himself. Even down to winding the coils. Good old fashioned engineering.
@@redcrow2006 indeed. Good stator and rotor build. Nice 4 pole 3 phase generator design. Happy days.
I too second this
@@sachin.c1211 I three third it.......... and my mate Paddy tree turds it.....
is it wired star or delta for higher voltage? maybe i also missed him explaining that
I've been enjoying your amazing videos for years Kris. As time goes by, I find myself continually blown away by the projects you take on and the breadth of your abilities to complete them. Then to top if off, you film it all and share it with the world, inspiring countless people to go for it and try a project of their own. People like you make the world an amazing place!
Just like me.. Except these projects eventually end. Mine are eternal
@@SLYdevil I m already a fully paid lifetime member of that same club 😂
@@SLYdevil Yea, my buddy says I'm excellent at starting projects.
@@SLYdevil Know & share the feeling..❗🙇♂️🤔
Tired of rebuilding Houses etc., just to vacate or relocate every time i think its done and comfortable..❗
In my retirement now at 77, as a Prof' Consultant i just want to continue with my Hobby in Bladesmithing and thats about it..⁉️🤔
Kris. Please don't feel embarrassed when I say, and know others feel the same, that you are inspirational. Well done and thanks as always for sharing your knowledge and journey.
I find myself so fascinated by every aspect of your journey (since you first walked your land) that it does not matter what project you are on. Your thought processes as you tackle each new challenge and the way you build what you need from scrap are well worth every moment!
Would you ever have thought when you were first building the roundhouse that you'd be at the point where you're making more energy than you need? Absolutely amazing, I love all the power content, and I simply can't wait for more building videos!
Now Kris @Kris Harbour Natural Building just needs to use the excess power to pump water up the hill, for DIY *pumped hydro energy storage.* :-)
@@YodaWhat Kris Harbour Natural Energy Harvesting
Yes, I think he had a vision at the start. & It's Good to see the thing come to gather to achieve it. I was born of grid no mains power or water much like him in 1952. but we lived in a of grid cottage. my first windmill I built was, by the use of a 6-volt Dynamo & the regulates & controllers of a ford popular. later & progress to a wood gasifier. That power my battery charging set' which was a engine driving a dynamo back then in my day the set's were army surplus. used by the army. now days there isn't a army surplus shop to be hade. LOL Later we migrated to a 12-volt dynamo. & to day it alternators that we use to charge the batteries. Our dump load was the cow shed light's & the second Bratty bank. We Never wasted an opatunity to generate Power. We stored all we could. No such thin as Soler panels. Things have come on a lot & yes, I think his work as done well. We get some people that often get the opatunity to deliver & contribute. Kris as been one such person. When so often as in my day we got them that would say it won't work, Or your just waiting your time. Or you need to be a qualified Electrical engineer to do that, Like him if I had listened to them, We would have had Nothing, in my opinion he Deserves an MBE. [ & i Nominate him for one] He as blazed a trail for others to follow . & opened up opportunity to power one's house of the grid on the cheap. Today but that debate i suggest is for another Day. Available to be had.
@@YodaWhat Use the excess energy to heat a big insulated water tank and then pump that to his various buildings to supplement heating. Then recover the heat from a steam engine or wood gasifier so that you're heating and charging batteries at the same time in the dead of winter. The rest of the year you can use solar heat.
You are one hell of an engineer !!. Thanks. Dave
The shot of the filings marching around the stator was fascinating
Yes, really fascinating!
Holy cow! Pouring resin over the hours you spent on the windings must've been a crazy intense moment. Way to commit, dude.
What a project! love the longer videos.
I always thought an interesting/useful dump load in the UK climate would be a buried, insulated tank of water that is used to heat a greenhouse through radiant underfloor heating pipes. I've never sat down and done the sums on it but the idea has always been with me... especially as temperatures dip and I wonder what could be grown in a heated greenhouse in winter.
check out some vlogs of all year round greenhouses in the north usa, they use big pipes buried circulating the air, sunken like gruber huts, citrus trees etc. grown in them, the north side is usually a bank of soil
Sand if the way to store heat . An insulated water tank full of sand and run water pipes through the sand as well as heater elements. see this video for an explanation ua-cam.com/video/kzj1PCA_jxA/v-deo.html
I too like dumpload idea, and underground water tank I know a scientist that has a very large tank that he just paints black lol. The problem with wind were i live is many nights there is very little wind. I would be tempted to heat with solar and use wind to run half the waterpumps.
A full hour! What a treat!
We love the variety on your channel. Hoping we do still see more of this kind of work. The building is awesome but also like to see all the aspects your have to offer. Great job.
I love videos like this because they make me confident that I could reverse engineer some level of technology if I were ever stuck in a time travel situation
A jigsaw or oscillating tool with no blade would vibrate the air bubbles right out of any future pours. Splendid work as usual, thanks for bringing me along.
Snow and -2°c here in B.C. this morning. Roaring fire lit and and a full hour from you👌 Thnx for making my Sunday Kris.
Another awesome and well presented video,,your engineering prowess just blows me away. Love how far you've come from sandbagging to a beautiful off grid homestead.
Longer the video the better, your channel is truly one of a kind. Thanks for sharing your life, creations, and innovations with us.
I am very envious and wish I had the no fear growing skills that you have, Kris. I have been paying attention to the detail you put into everything you touch and the quality. Also, the 4x4 you fixed is crazy cool! You are a master at just about everything. Thanks for the video!
Kris. Have you thought about dumping the excess power into a water heater rather than waste it to atmosphere? Or use both! i.e. when the water is up to temperature it switches over to the 'air' heater.
That is a fantastic idea !
There is only one Harbour in a storm ! You are the definition of the UK backyard boffin. Seriously impressive skills from design through fabrication to assembly - always comes together!
The things I learned today watching you work, just blows my mind. Nice work sir!
Hi Kris, yet another amazing video, extremely informative. Never apologise for videos being long, anyone not interested can walk away or turn off. From my perspective, if you filmed all day, I'd get nothing else done because I'd be glued to UA-cam. Looking forward to the next one 😃. Great work, well done.
I've been watching your videos for over 5 years now Chris and come to the conclusion that when you put your mind to it you can build anything with your knowledge and materials at hand. Another great video. Well done Sir 👏
Kris, brilliantly constructed in every aspect, design, build, test and production of physical and video. love watching. Keep going bud.
Hi Kris, you should know that when SSR's fail, they usually fail closed, so that part would be inherently safe as well!
Awesome stuff!
Really nice! The reason you point the blade axis skywards slightly is to give you a little more leeway for blade deflection towards the tower. Prevents the blades from hitting in high winds / bad conditions.
Just a thought. Also the force vector from such a tilt pushes the wind turbine nacelle downwards, instead of upwards. So mechanically less issues with the nacelle flying off ones tower?
@@LAZASASIf I remember rightly Hugh Piggot reckoned it also helps turning when the wind veers
Hi Chris, 32:20 the reason why the blades are tilted back at a 5 degree angle is because on bigger wind turbines blades flex and would end up smashing against the main upright pillar and destroy itself.
Great stuff as always Kris! I had always envisioned a dump load on a wind turbine as a heat and/or water heating element and use it to heat a body of water within my green house, which will then slowly be radiated out to prevent frost. I bet your workshop will warm up nicely from on ocassion.
Really did enjoy this long episode Kris (kind thoughts to Dot), so interesting to see you making the winds and constructing the wind turbine. Great stuff. I do agree with your concern about the tube at the top of the pole being a likely fracture point - but a stout bit of sleeving should do the trick. All great stuff! And building to look forward to as well !
Thrilled to see you even wound your own coils
I wind my own guitar pickups, 5000 turns of 42 Awg wire so that was cool to watch 😊
Great job on piecing together a very interesting video Kris. Always amazes me how much of a renaissance man you really are. Need power? ...build me a hydro, solar and wind system... need a workshop? build me an earthbag workshop. need some lumber? ... fabricate a sawmill. Simply amazing!
Loved the video! It's the 1st of your videos I've watched and found it to be quite inspiring. I think I'm going to pursue some more DIY projects myself because of it. I can't help but feel more and more these days like our time in the world today having all these luxuries and conveniences is limited and will soon come to an end leaving all of is who arent prepared doomed to an unpleasant demise. Being prepared and having the ability to survive on my own is becoming a top priority and having people like you around to help me establish a plan is priceless. Thank you for taking the time to share this information.
I love watching you build wind turbines. I've watched you carving the blades probably 10 times now, your craft is amazing.
Same goes for James Biggar. He made his Reaper turbine and posted a video here on YT. It's jaw dropping as well.
Well done Kris, always something interesting, look forward to seeing more of your plans come to fruition.
Put a "Lamp Test" button on the elements to check they are operating ok. A light comes on and you don't have to do a lot of double checking.. Realy enjoyed these video's pf yours and will look forward to the next phase in the homestead growth. Keep up the good work :)
Thanks Kris for sharing your knowledge with us. You really give me a sense of belongings to my engineering field and looking forward for your new videos
First time seeing one of your videos…, Wow! I could watch these videos all day. How satisfying it must be to provide all of that for your family.
Great work as always Kris... i can't fault your initiative, technical know-how and sheer tenacity on all your endeavours. Power to ya'mate!!!
Awesome job Kris! You do beautiful work and love how you explain things as you go. Thanks to Dot for the drone footage.
Hi Kris, looking forward to your future 'venture' ------ building the barn.
You've proved yourself to be a man of all trades & this windmill upgrade video is more proof that gas/coal/nuclear power sources have real competition.
From round house to power house you have been a source of imformation to the young & environmentally conscientious & hope to the older folk like myself.
Thanks for the upload, RGDS, P.h.
Very nice work!
Another tip, if you make the coils slightly trapezoidal you can pack more copper in the windings.
Only the radial sections of the wires generate electricity as they pass through the magnetic field.
Personally, I decided my interest level by clicking on the link that sent me here, good sir! 😊 Wonderfully done, Kris! I have no plans to do any of that for myself but I sure do enjoy watching you do it 👍 Excellent work! Thank you!
Excellent content Kris, very enjoyable watching. Must say looking forward to the barn build, excited to see what master piece you'll conjure up this time. Slow & steady, as always.
Fantastic work Kris, firstly the effort putting this full system (hydro, solar and wind) together put for also filming it all and sharing. Thank you very much and all the best to you and dot
It was very helpful you explained each step so clearly. Thank you for respecting how some of us really wish to understand your process. The hook up to your batteries and heater through logic panels were especially good ex planations for us unschooled folk. The range of skills you are mstering is impressive. I love these vids!
About the twists in the cables - either a chain (to stop excessive twisting) or a spring which returns the turbine to it's starting position might be worth considering (similar to springs on gates to close them). This may take a while to source but could solve the problem. If you don't sort this and the cables are going to be stretched, although this doesn't happen very often, having them as a standard serviceable part that you can unplug and replace might be worth thinking about for future designs.
Trouble with this is you could end up throwing power away when the wind turbine is prevented from fully turning into the wind, and this situation could last a significant length of time until it resolves. Also it could prevent the turbine from furling in strong winds which could be catastrophic. Just another unfortunate trade-off in a system with no slip rings.
Thank you Kris for sharing all of the details of this build! Great work and a fantastic video!
Thanks Kris, very interesting.
I have to arrange a load dump for my off-grid Solar into a hot water tank, so you've given my lots of useful ideas.
Thanks again.
Kris - This is such a fantastic video! Thank you and your wife for posting! You have definitely helped me to explain this type of set up to my wife. Blessings to you!
Excellent job of not only going thru the fabrication and construction of your wind turbine, but your knowledge and explanation of how it functions is at the level we can understand.
Kris, you're a rock star. Honestly, I cant keep up with how many things you're teaching yourself. Extraordinary. I am VERY much looking forward to the barn build, perhaps you can feed us some teasers like a picture, and or material you're going to use in the creation of the barn. Strawbale? Board and Batten? Cheers mate.
Doubt I'll ever get to doing something like this on such a scale, but it's honestly a new dream I feel like I could pursue somewhat after watching this. So, thank you so much, this was an amazing video and good luck in whatever projects you tackle next.

Hey Chris, a barn build will be superb!! Though the power generation videos are interesting, I do prefer your building constructions. That said, I appreciate that you are sharing a documentary view of your life, and the thing about real life is that it does tend to dictate the direction of travel so I am absolutely not asking you to tailor your content to appeal to my preferences. I think my fascination with this channel is continuing admiration for your choice to escape the rat race, and deep respect for the hard work you continue to invest in realising your ambitions. This isn't a soap opera where the plot is contrived to hold the attention of the largest possible number of viewers, and thank goodness for that, soups are aweful! Far above any trivial observation over my preferred content, I'd like to say thank you for sharing your interesting and exciting journey with us, long may it continue!!! Thanks mate!!
Just something you built in your spare time? Impressive!
Absolutely love your channel Kris. You are an extremely intelligent young man. Able to use what you have to do what you need. Love watching you and your wife’s journeys. Thank you for sharing brother.
Thank you! I wish my Dad was still around to share this with, he would have been fascinated and also might have had “interesting” insights. He was an electrical engineer back when high voltage lines were being built across the UK.
Incredible. Just keeps on improving year on year. remarkable. Looking forward to seeing some kids on the channel to pass on all that wisdom too! Thank you for sharing. 👍👍
Very impressive! I recently watched some Living Energy Farm videos on DC small scale electric systems using nickel iron batteries. They also have solar DC to power their shop, interesting stuff. Love the step by step approach here, reminds me of physics lab back in college (wrapping copper wire, anyway).
Just built a large off good farm and house off grid using victron kit love to work with kris on a water turbine
If you flash your resin with a torch it helps release a lot of air bubbles. Great work!
You should have a medal! Thanks for your thorough way of explaining: Thanks for taking your time to record and put all this here together. You are a champ and a hero. Thanks a lot.
The free education I get from this channel is awesome! Thank you for lighting the way.
Kris I find this stuff quite fascinating. I love watching you at work with all your High-Tech machinery. I always look forward to your presentations... I must admit some of the power stuff is a bit beyond me but I learn as you go. You have come such a long way with your property... and lets not forget your cat!
Excellent video. Your multi talent knows no bounds. You have developed 3 complementary systems and the best I have seen. I look forward to new projects.
Really impressive, Kris.
Look forward to the barn build videos too. Keep doing what you're doing.
I just took a quick glance at your channel and it's gonna be one of the ones I can't stop watching until all is processed and understood! This is how YT should be utilized IMHO. Just getting started. Excellent work 👍.
Impressive skills! Always look forward to your vlogs.
Great video Kris.
It literally makes me physically sick how difficult it is for average Joe Public to put up a usable wind turbine in this country. Planning permission... Lack of companies who offer turbines... and lack of small scale (domestic) wind energy expertise.
Love seeing this kind of thing.
it's as if someone would want to intentionally stifle the development of green energy.
Kris you're living my dream. Great work. Now I have to go and get parts for my own wind turbine. Thanks for sharing this.
I’m never not blown away by your mind! Your brain is in computer mode all the time and it’s fascinating to witness really. I’ve been watching since you first showed us this land, what you’ve done since is incredible. Love the content and look forward to seeing all your creations and genius at work.
Your well researched, well experienced applications of power have been the most rewarding in terms of spending a little of my life quietly observing yours. Inspiring of you to consider where to dump a potential of excess energy. A heater is brilliant in your corner of the world! Perhaps as integral to a real world application of sand battery heat storage...whoops! There I go gushing on again for all the enjoyment you continue to provide in this well presented power video . I'm sure you know we all worried for your shoulder on the lift...but I'll bet Dot let you know that already. Thanks for another great one!
Use quick passes from a blow torch to eliminate the bubbles. On melamine, there are release agents (wax) that make it real easy. If you use wood again, you can use wax paper between the two. The resin won't stick to it.
Yes on the blow torch or heat gun .Misting with denatured alcohol also works .That's how the epoxy artists get rid of bubbles
Most excellent Kris. Length was no problem. I enjoy watching you create your projects. Keep them comming.
As an engineer, I really enjoy watching you work through this, problems and all.
I've been waiting for this video ever since you mentioned it in a video a while back. Sounds like this will make a bonkers amount of power for you too.
It's really cool to see the effort you've put into various small or not so small improvements culminate to a really bitchin setup
My takeaway from this video is that your expertise in power generating is amazing. I understood very little of the details at the end but it was fascinating. Your next project for power should be extracting the lithium from the ground at your place to expand your battery array!
Brilliant video again Kris. This is where I will come when I want to build my own wind turbine. I guess this is all a big learning curve for you and it is great that you are sharing it with us.
Brilliant, well played, love you showing us all what you are up too. All the best as usual. Many thanks.
Excellent work, this is the best I have seen on this topic. I can't wait to see what you work on next.
Excellent Kris, I wouldn't worry about the SSR. It's into a purely resistive load and they tend to fail short anyway. Really interesting video💪
Feels great when a long term project comes together.
Congratulations.
Very Cool video on Upgrading/Rebuilding your wind turbine, looks very well built ! Thanx for sharing another great build, Kris !
I'm very impressed of your skills.
Lots of inspiration for me! 🙂
I'm also using a dump load approach - but for a solar-thermal system.
In my case this is a 4.5kW radiator, which consumes any heat I can't store.
Since I installed that, the wear on my system significantly decreased.
Fantastic job Kris :) All of your projects are really exciting to follow :)
love your channel Kris. Insanely inspiring! Can't wait to get onto some land and start our journey. Love all your vids but the power ones especially. Thanks for sharing.
Thanks for the update Kris, I enjoy watching whatever you're doing, so just keep on keeping on. 🙂
Impressive stuff! Thanks for taking the time to film and share it.
Really love everything your doing amd have done. Constantly learning and improving. Watched all your videos and you've come a very long way, from when you were making bowls and your first vertical wind turbine.
Look forward to what you do next with the barn.
Well done Kris 👏
I been watching for years...amazing. Most of the time I know what you are talking about so it’s all been enjoyable.And now the barn...very enjoyable.
Only just discovered this video, though I've seen several others of yours. Brilliant content and presentation - thanks for sharing your ideas and work.
You could use a voltage sensing relay to trigger aux 1 if for some reason the voltage on the turbine gets to high due to the a malfunction of the ssr as you mentioned. Sad to see less energy projects in the future, however I'm always pleased to see your other videos as well:)
It seems SSR:s usually fail in ON position so less worries.
Great progress. Being a pessimist, I might be tempted to put a voltage monitor across phase wires ultimately feeding an alarm, just in case the rectifier fails and allows the wind turbine to run without load. You have a switch to short out the phases but it requires manual intervention.
I just enjoy watching anything you make and reasons behind them. All makes sense to me.
Every video is better than the rest. I know the basics and have a small solar setup myself but to actually build an electric generator is very impressive ,well done.
Nice work mate, always interesting and informative, love it. My only point is copper grease isn't a lubricant it's an anti seize, it will wear the bearings out really quick as the copper is abrasive. Just sayin, would hate for you to get it mounted only to have to take it down fore a bearing failure.
Yeah I know its not ideal but its not a wheel bearing. its only going to turn very slowly and not produce any heat at all. I will change it next time its down. The bearings were old anyway. they had come out of my Land Rover when they needed changing.
You can use a blowtorch to quickly remove bubbles from resin. This project is a bit big, but you could also use a vacuum chamber to draw them out
The bubbles were trapped under fiber glass. thats why I had problems getting them out. you can see in the video I had to snip the fibre glass to let a bubble out. im sure a vacuum would work though.
@@KrisHarbour Ah makes sense. If you're going to do much resin work, building your own vacuum chamber would be an awesome project!
@@KrisHarbour though useful, you don't need to mess about with vacuum chambers: if you wet the mat out with resin before putting it on it'll help stop air bubbles, so will agitating the mold when you've poured resin into it - block of softwood in a recip saw or something similar will make the bubbles rise out. (You may have done this anyway, apologies if so. I know how armchair UA-cam comments annoy you!)
Hi. First time watching Kris’s videos. My first observation is he has an amazingly well equipped shop.
Nice job! A solid state relay usually fails short. This is often a problem but if I understood you correctly this is what you would want to happen in this scenario. Still, I'd quadruple the rating and buy from a reliable source.
For future castings like this, a vacuum chamber will be your friend to get rid of air bubbles and ensure full resin penetration of the coils. You will also want to gel coat the mold so the resin can't stick to it.
A practical alternative to a vacuum chamber would be a vacuum pump and bagging. See Mad's video on the Sail Life channel where he makes a new rudder for his yacht.
@@poruatokin most people who do resin just jiggle the mold with a sander
Bloody epic!! In awe of your engineering abilities just stunning work. Really enjoy watching your videos
Watching this with a mate from Vestas and he is quite simply astonished. Magic.
Good work Kris, fascinating as ever so keep them coming. It would be good to see a vertical axis version to address the changeable wind (we have a lot of that here in Wellington, NZ) and more urban/suburban installations will get inconsistent, buffeting wind.
Shame you have to dump the excess energy - any thoughts on domestic scale thermal energy storage?
