- Installing a wind generator for the off-grid ham shack.
Hello Operators.
In todays episode of OH8STN Ham Radio we are talking about generating off-grid power with a vertical axis wind turbine. The goal is a hybrid system using both a wind generator and solar panels to power an off grid ham radio station and Winlink RMS Gateway from my home. The Vertical Axis Wind Turbine or micro wind generator is part of the Winlink RMS Gateway project you may have read about on oh8stn.org .
The VAWT project will be combined with the solar panels already up on the tower, and the diy Ammo can 576wh LiFePO4 battery storage system we built on the channel last year.
Combining the Wind Turbine, solar panels and Lithium battery storage help create a hybrid Wind/Solar off grid power system, which should easily keep the Winlink Gateway powered up, when there is no sun.

I have been looking for someone to explain turbines. I live on the coast, see all the sailboats with wind and solar, and wonder how it was configured. I am sure there are marine electronics that know this stuff. Thanks again!!
Ultimately these turbines are just AC generators, with a DC converter on the output. The higher the voltage of the system you're trying to power, The higher voltage motor your turbine needs to have. The mistake I made with this system was using a twelve volt motor when I should have had a twenty four volt motor. That's what i've written much more usable energy at low speeds.
@@OH8STN I have heard that from another youtube.... Use a 24 volt becouse it statrs spinning at lower wind speeds.
Thanks for the reply
Thanks! Looking forward to adding wind power to my setup.
Thank you 🙏
I alwys watching ur vedio here from phillipines sir.
Thank you 🙏
@@OH8STN sir i have a question,about installing 12v windturbine off grid?
I have 12v windturbine 300w sir,then i use PWM solar charge controller for 12v windturbine off grid,my question sir it is compatible PWM controller for 12v windturbine sir?.my controller rated 50a 12v/24 volts.
terrific video Julian 73 from kb2uew
Thank you. Now I'm trying to find a reasonable charge controller so I can make part 2. We've had some pretty bad weather since it went up. Handling it like a boss so far.
What a great idea. thanks.
Missouri wind and solar. A long ways from you but they know their stuff.
Northern Arizona Wind and Sun rock as well. As do the folks at Sunelec Miami, and Midnite Solar.
OMG the Savonious Rotor was the first research I did back in the late 80's super cool how far they have come while never changing :-)

Yes, very happy to have earned about this one. There certainly are better options, but this one is hopefully a learning tool.

You are right! We do need to set up more infrastructure for all of grid folks! Great video! Thanks!
Absolutely. City, county and states need to revisit their building codes for new home builds to allow each home to have back up battery power and off grid applications for emergency power for when the local power grid goes down, especially during disaster events. Meaning, allowing homeowners to have solar panels, micro wind turbines and battery banks.
Example, our island’s power plants burns fuel oil and coal to generate electricity. Next year, the coal power plant will be taken offline and dismantled, leaving us with two power plants also.
At the moment, HECO, our local power supplier, is offering free batteries for back up for those that have roof top solar that is connected to the grid. There seems to be a real power grid concern after February of next year but to what extent is currently unknown. Possible power surges and brownouts maybe?
I never thought of wind power for EmComm. Thanks for sharing!
Thanks for the comment. I think it's something we really have to consider with fixed repeaters and RMS gateways.

Maybe someday I'll upgrade to Extra Class, but I'm not a rag chewer and there's plenty of DX if I want to chase it.
Thank you for all you do !
I have An idea that might help with the turbine during the winter months. Use that small form factor pc that you're going to use to be able to toggle on/off a miniature heating element to defrost the turbine if it gets frozen. That way you have a way to defrost it in the middle of winter without having to risk climbing up the tower. Toggle it on for a while to get it spinning again and then toggle it off.
It's a good idea. I'm not sure though how much heat would have to be generated in the winter temperatures here. It can get down to - 35 to - 40 in the worst of times. Average is between -10 and -20. I was thinking about running some voltage back up to the wind turbine to spin it like an electric motor. This might be more efficient than the energy required to heat an element. I'm not sure and hopefully it won't get frozen.
Hi Julian this was a great video and that’s a very interesting wind turbine. To have solar power and wind turbine, That is a great use of power for the amateur radio.

Thanks Steve. It seems to be the only way to stay powered up, all year round. Two extremes really. Either too much sin, or too little. Wind is the only "reliable" alternative the other half of the year. Hopefully it works. The idea is sound, my implementation might need help though.

After the power issue in Texas USA last year, I will be interested in seeing how this system works during the winter months when the biggest enemy will be freezing winds.
Excellent point.
Also my biggest concern is snow and ice. It will be a no-go if maintenance is required weekly to get it moving again. 65N is definitely this VAWTs worst nightmare in winter.
Won't be holding anything back. We'll see if it performs.

Naah... I'm going to take a trip over the border here a bit northeast of you to retrieve an old soviet RTG. Cheap, no moving parts, it keeps you warm in the shelter and it emits a cozy blueish glow in the dark - and as a bonus you get a nice suntan when sitting holed up within a 10 meter radius. Probably environment friendly too - my friend at the Nerpa shipyard guarantee it! 🤓😁
If you're interested, I can fit two of those in the back of my 6x6 Volvo off-road truck. We split the customs "fees" 50/50!
Lol! I'd like to see that one :D
Great information! 🙏
Thanks but it isn't there yet. Lots of work and measurements to do from next week,
Always good to hear from you.

This is an excellent idea. Here in southern Canada we're only at 44.29 N Lat.and so have somewhat more winter sun than you do. We have 16 solar panels on our roof and a substantial LiFePo battery pack to store all that juice. All the same in the dark days between December and February getting enough input from solar is a challenge. We've consider a wind turbine but have always been put off by cost and the technical problems with getting it high enough to produce usable amount of power. Very recently we erected an 11 meter tower for 2 meter antenna's This really is not tall enough to get a wind turbine at a decent height. Even so, I suspect that it might still be worth doing because we also get lots of wind and turbulence or not I think a VAWT might do well on our tower. You've certainly given me food for thought. 73
Nice tower
Thanks, it has been quite the workhorse

There are even better Vawt. They have sails that can shrink in strong winds. They start working at a wind of 2 meters per second, and when the sails are assembled they can also work in a storm.
Thanks for the info. Can you name a particular brand? I only chose this one because it was well-built and seems as if it will survive the winter.
@@OH8STN In the last 14 years, a dozen manufacturers have made a prototype ready for production, but then gave up production for unknown reasons. Some of these specimens can be seen in this list. ruclips.net/video/IX27qvPlHsI/видео.html
Thank you for this video, Julian. I am in the U.S. I just googled VAWT and a bunch of them came up, but not the one you have. Would you mind posting the make/model information? I really need to look into this. Thank you and 73 de K4VIN.
There are a couple or few Chinese MPPT controllers for wind (I saw one years ago and you have that one in the video) but I am not sure how good they are. There is the American made MidNite Solar solar, wind or hydro MPPT controller series good for 150V, 200V or 250V DC max input voltage. You program a curve of output power (current actually) vs. input voltage. This setting, if properly programmed will allow the turbine to speed up when the wind speeds up as to keep the tip to speed ration more or less constant. But that's for a HAWT. For a VAWT I would imagine the curve would be more of a straight line ?
Not sure if MPPT for wind would help much with a smaller turbine but if your VAWT gets really good wind, it might help keep your battery charged better than not. DIdn't quite catch how much power and energy output you have gotten with that HAWT so far ?
K7IQ
I'll have a look at the midnite solar. That one keep popping up in my searches.
thanks

Cool stuff. Would be nice to catch up in person one of these days after many years, DE OH8GDV
It would be nice. I'm a little older, a little grumpier, ... 😂
Biggest issue with wind power is noise. I don't know what you have in that regard so far but am curious. Having a wind genny on the boat was perfect and never was without power but it also made sure that any place I pulled into I ended up at the farthest reaches of the mooring field. Even if I told them it was shut down and will remain so it still made noise sitting still in big wind.
I have been interested in the Icewind www.icewindusa.com/ but again no very much info on noise levels past some people saying its very quiet. I know savonius rotors like to howl so give us some video of it running with sound please. You might just be raising an Air raid siren.
👍👍
Thank you

This is Assume, I do think the combo of wind and sun is the trick. How did I miss this 4 mo ago?
Thanks. The only issue with the wind turbine is the maintenance during winter. Sometimes it freezes up and needs to be released. Other than that, it's been a pretty good combination.
ElvWIS does not ship to the United States. Can you recommend an alternate VAWT supplier?
Does this wind turbine have a gear box for when the wind gets too fast?
It doesn't. It has a breaking system via dumpload.
nice setup you have there :). i do have a question though; what would be bare minimum for mobile vhf/uhf and HF setup? right now im in process of making mobile ham station, but must be small enough to fit into 65 liters backpack or small motorbike trailer (my preferred method is still MX bike).
This is a trick question which most of the RUclips channels disagree with me on. You can take a radio like the Yaesu ft-857d which is a preparedness favorite. It will do VHF UHF and HF in a relatively small package. It's the same with Yaesu ft-891. The problem with these radios is the current consumption. Just sitting there on receive date require at least 1A all the time, even when they're doing nothing. This means your radio equipment will be small enough for your backpack, but the battery to power your radio equipment for any length of time will be ridiculously large. Now if you remove UHF from your requirements, lots of opportunities open up. Take a look at my video Icom ic-705 and Microsoft Surface. Never mind the data modes, just watch the entire video. I use a qrp radios and external amplifier because the current consumption is ridiculously low. Now I don't have to carry a 30 lb battery for my 1 pound radio. Check out that video please oh, it will answer lots of questions.
who made the wind turbine and what are the spec for it looks interesting thanks Kj6pyv David
how about one of these Pikasola Wind Turbine Charge Controller Mini Wind Turbine Generator Controller?
Let me check it out. Thanks for this, i'm really at a loss.

Would like more data on the wind turbine itself. Is it a repurposed generator, or something commercial off-the-shelf?

@@OH8STN vielen dank!
Could you share your tower wind loading calculations? I'm a bit concerned about that.
I agree, especially with the batteries he wants to use. Plus, raise the turbine three times the height comes with it’s own set of problems. Vertical wind generators don’t require as much height to be effective, especially the model he has. Plus it doesn’t hurt to use the trees as a form of protection for the turbine. Less chance of freezing up in the winter months and getting less snow on the blades and a lot less climbing of that tower in the long run. Raise that turbine only 10-15 feet is maybe where it will be most effective to attract land deflection winds. Only my opinion…
I forgot to mention one of the main reasons I prefer golf cart batteries over all other batteries available. Main reason, they are cheap and very forgiving. You can charge them all the up, drain them down to nothing and then charge them back up again without any damage. Since I use a combination 6 volt and 8 volt golf cart batteries in a series and parallel circuit to give me just a little over 14 volts, a benefit for all my radios for EmComm. The last reason why I use golf cart batteries may surprise you.
A 12 volt system usual sits around 12.8 volts at full charge. I also forgot to mention that I use DC to AC modified and pure sine wave inverters since I use four all together, with the pure sine wave for my living areas where all the computers and TV’s are also located.
So on a 12 volt system, the inverters will usually alarm out between 10.8 and 11.8 volts depending on manufacture standards. So that gives me one volt of leeway or about six hours of power before the alarms but on a 14 volt system, I have between 20 and 24 hours of leeway depending on the load. During those hours, the sun comes back up again, the solar panels start charging again and the wind starts blowing again during temperature changes.
So forget about those fancy batteries, use what is going to be readily available when the SHTF. Same thing with solar panels, the shipping costs for the big solar panels is just not worth it. I usually get free shipping on 100 watt panels, especially if you order two at a time.
Also on those golf cart batteries, I don’t use water, I buy battery electrolytes which only costs me $11.99 for 6 quarts at any auto parts store and only have to add to the batteries every other year. Golf carts batteries require a much higher current to start gassing and since I don’t a regular golf cart charger or a standard battery charger from Walmart or Sears, the way I charge is safer to use in the long run. Safety first…
@@digitaldreamer5481 good point, but Lifepo an use all the amperage not onlyv50% before damage, have continuous amperage distribution and don't drop on heavy load and the most important thing for me it's charge with minimum amperage and really fast (maybe 3 time faster then old technology battery like golfcart)... Ps don't forget now Julian live in (really northern) Europe and golf is not so popular sport even like "pelotas "... We must always contextualize. What do you use according to your needs and availability Where do you live!
Thanks Todd
The LiFePO4 battery storage I build isn't fancy ;) It is lightweight, requires zero maintenance, doesn't vent, won't catch on fire, doesn't suffer from Peukert's law ,and most importantly is also man portable. It can be moved between my home station or deployed portable in a day pack if need be. The cycle life is very favorable as well.
I have seen commsprepper with in some respects a similar setup as you mentioned. I don't doubt the golf cart battery effectiveness, but the price will never bring down the size and weight to something which can be easily redeployed
The "fancy" bits of my system are the wireless shunt for battery monitoring. It was important to monitor and log incoming and outgoing stats. How much current to system is using or generating, voltage drop over time, capacity drop over time, heat during load, ... The battery part of it is very simple. It is the battery and power monitoring which is somewhat more complex. It could be made simpler, but I would loss out on the logging.
Question. "especially with the batteries he wants to use."
Why would the type of battery chosen make any difference for this project?
Sure Jack, if I find the planning documentation from two decades ago.
I may not have shown it in the video but there are actually two towers, one inside the other. I will never lift the inside tower, so loading is the combined strength of both. Moreover, additional reinforcement and guy points will be added where the turbine is mounted. I didn't mention that in the video.
Sorry to be a party pooper…. But…. Speaking from Wisconsin winters…. On the shore of Lake Michigan ….how is this going to do with wet sleet that freezes the turbine? Once it’s locked with ice it’ll be that way for most of the winter. I’m not seeing how this would be a dependable augmentation to a winter system unless there’s a way to thaw it intermittently.
That's not being a party pooper! It may end up exactly as you said. The thing is, we don't know unless we actually test it. It's one thing to believe it won't work. It's another thing to test throughout the winter, then study the results. I'm at 65°N on the sea. Have exactly the same concerns. Let's see!
How did you manage to get approval for such a tall tower in that residential area?
Living in a free country helps (No HOA in OH). Also having former military as neighbors on all sides. The thing which put it over the top was the tower being a lightning magnet for the rest of the neighborhood.
73
Julian oh8stn
Are you also former military?
Your terminology and lexicon suggest it.
@@OH8STN Nice idea - if the lightning hits poor Julian, it won't hit us - I should sell this to my neighbors the same way too. 😂😂

i suppose i will need to get another battery as well... this gets expensive quick, so i slowly build my system over time....
is that a telescopic aluma tower ?
It is 👍
@@OH8STN wow ! that is some serious stuff you got there... it's a dream to have such a tower here but out of budget being in Canada unfortunately... the tower itself is not that expensive but the shipping, exchange rate and costoms hit hard here... you lucky you... how have you been able to import it to findland ??
Please don’t fall off the damn tower.
I've got excellent safety equipment, and the military taught me how to use it. The tower is in good shape and I wont take any risks. SO it should be fine.

Wind performance is going to be poor unless you can get 10 meters or so above the tree line. The tree tops slow the wind significantly. The slower wind plus the abysmal efficiency of a VAWT means this isn't an optimal solution. Sorry man...you'd be much better off flying a 400 W marine HAWT on top of the tower.
Yes, that ws mentioned in the video. Hopefully it will be at the 10 meter mark or even a little higher. My concern is the twisting forces put on the tower in heavy winds. I chose a VAWT in part because more can be added if performance isn't adequate with a single VAWT. A HAWT is a no-go on top of the tower for maintenance reasons, and the potential loading it puts at the weakest point on the tower.
Thanks for the feedback. Lots of testing and measurements after the lift.

Julian oh8stn
@@OH8STN Maintenance has to happen regardless of the axis. if the device meets your mission needs, it's a win, especially since you already have the sunk cost.
My wind is about 400W and made from a washing machine motor. I planned to replace it with a Piggott axial flow HAWT, but with PV under 31 cents a Watt, it doesn't make sense for me to grow the wind collector. 73
