I found diy soap kit shops sell good quality KOH. You actually need just KOH and water. Buy a few lithium AA batteries (primaries) for metallic lithium. React it with distilled water to get clean LiOH. You need 1-2% in your 20-30% KOH solution. And it's not mandatory. I actually run on LiFePO4 now but I have some 1950-1960 NiFe cells and some NiCd ones. I wanted to get my house running on ukrainean NiFe (the old ones, pre 1995) but that shit happened just as I was negotiating with sellers... Damn, like 30-40€/kwh... NiFe are immiortal. The electrolyte isn't. Make sure the vents never let air in as KOH will scrub CO2 from air and become KCO3 wich will flower up the cell and degrade performance. They need constant care, yearly washes and refills but that's all.. I can send you a link of my Romanian site I bought KOH pellets. But I do recommend getting yourself some LiFePO4. They are just so cheap now, ~30¢/wh. They are sensitive to temperatures, unlike Ni cells but carefree for their usable life. No refills, no washing, no topping... I don't think you need to know this from be but for anyone else, all types of rechargeable batteries contain nasty chemicals that can burn, blind, disable, mame and kill. Not to be toyed with. None of them.
Dont know if your sorted but here is a link : bizpressions.com/products/potassium-hydroxide-flakes-lye?variant=39687987888192¤cy=USD&srsltid=AfmBOoquvFe5EB55ljdStXRZePezMve5J7fJedILZTLFueeGXMPmGccMeQU
Hello sir, I have a wind turbine and my microwave and washing machine are making a high pitch sound. Do you know why? I have 218-222V but I wanna mention that I don't have the ground installed yet. Thank you
I have three wind turbines 300w 700w on a 12v battery and a 2000w on a 48v 14.4kwh spells kit, the dump load for the 12v battery is a 300w 48v scooter charger ad the dump load for the 48v battery is going to be a sand battery with hot water pipe through feeding a instant gas boiler up to 70degree and another sand battery (to stop water steaming off) in the shed. Thanks for reading
Istabreeze i700 getting 450watts on a 40-60mph 200watts on a 30-40mph, yes 30-35mph will make more power than 25-40mph, unless three or more wind turbines are positioned 30m+ apart flattening the charge current, when 25mph 75w is being generated on one 40mph 250w is being generated on another and so on telling the bms it has a steady charge,
I don't know if it can help, but in France there is a seller who sells these batteries (he imports them from China). He also provides the electrolyte. Maybe he can send it to Portugal. The name of the company: Permabatteries.
What kind of connecting wire did you use to connect the three red leads from the generator down to the three blue controller leads? How did you connect them?
I have a PIKA T701 now for ~8 years. Rated at 1,500 watts @ ~25 MPH and yes it does it. 10’ diameter blades really works well. Wish I could post some pics for you.
depends on your wind location and the wind turbines characteristics, some can make good power in fairly light winds typically large heavy turbines that rotate much slower then you have smaller turbines that need higher winds and high rpms. many genuine 2 and 3 kw turbines can make 1000watts in under 15 mph winds. small micro windturbines are just a help otherwise just go nuts with solar panels and batteries so even in crap weather your atleast making some power.
Absolutely! We are not in an ideal place for wind power generation. I am learning now we would be better going higher or bigger to combat the turbulence issue.
This would be a dream for me.... I envision it as a man-cave cabin 15' x 15' with efficiency kitchenette/living room/sleeping area and screened in porch with a view upstairs, workshop area downstairs. A turbine rated for 500w probably (definitely) isn't going to be enough, so.... twice the rotor diameter please. What about having a companion tower 25' high with solar panels stacked vertically and this tower could be used to help raise or lower the main tower for maintenance. At the top of the shorter tower could be a domestic water reservoir (a big plastic barrel) to have water pressure for the cabin.... ok I'm daydreaming
We attached the turbine to the pole first when it was laying down, as well as the 4 supporting cables and then between 3 of us, we raised it vertically and anchored the cables to the ground. It was pretty straightforward in the end. The cables have adjustable tensioners, so we got it spot on verticle.
If you refresh the electrolyte, add some lithium hydroxide. Its a dopant they use to extend the life of the electrolyte and improve efficiency. The Chinese cut back on them according to the original literature (of the cells i tore down). 80 grams is what they originally used and they cut back down to 40 grams a liter. I was not impressed by the chinese cells. A lot of expensive for them to cut corners, especially since those corners saved a few dollars, nothing major. Good luck!
My dude, check John Daniel´s youtube channel ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QSfWnIscDTM.htmlsi=lYT6R3czaNbAiiWN The guy shows how to achieve the max rated power from the turbines. His knowledge is gold. I made my 600W turbine, to produce 700W from his methods. Stop using those controllers, they are limiting your turbines. I created a controller using an arduino. My turbine now is capable of producing more wattage than what is advertised from the manufaturer. You need electrical consumption to get to those numbers, of course, otherwise it will be wasted on the dump load resistors.
my panels don’t see sun for 3 months a year. the rest of the year i have more than enough sun i can’t use power fast enough. my house uses 6kwh a day. 100w over a day is 2.4 kwh. over a week 16.8 kwh that would allow me to run a generator 1 time a week instead of 2 times. the add more panels isn’t always the best answer
Do your homework :) I have learn't bigger definitely seems to be better and positioned in a way you get minimal turbulence, so as high as possible and away from anything that disturbs the wind flow.
Mine have been working great for 12 years. I have not changed the electrolyte yet(But that is on the list to do) Also I run about 1/8 to 1/4 inch of mineral oil on top of the electrolyte.
A wind turbine seems to be a very poor investment compared to solar. I don't know what your total costs were after building the tower, and wiring? Wouldn't an additional 300 watt or so solar panel cost less and return more power? I am currently in my homebuilt solar powered RV in the Mojave desert in California. I recently looked once again at wind turbines to supplement my solar system to see if they had gotten better lately. It still seems that the retun on the dollar is just terrible compared to solar panels. Solar panels also last for 25 - 30 years. How long do these turbines last?
@@Warrior-Heart They always seem to promise a lot more than they deliver. I would love to see them improve, but they don't seem very practical yet unless it is really windy where you live.
Hello, can you please help me. I have bought an Instabreeze 2kw 48v and I have a chinese Hybrid Controller 2kw 48v but it seems that it doesn't charge at all. When i connect only two wires it starts spinning and It shows that is charging but when i connect all 3 it slows down (no brake) and only charge up to 50w when outside are strong winds, no matter how strong they are the turbine is not spinning fast enough. The brake works fine and I had winds where it came active. I've tried to disconnect two wires, it starts spinning very fast when i connect the other two it still charging good for another minute then it slows down again for no reason, no break active. Thank you in advance. I have struggling for 1 month and still can't fix the issue.
I live off grid, in middle of america, flatest land on earth, we have a wind farm north of us that has around a 150 huge wind turbines. We have a huricane windpower turbine, vector 1500 watt, and its a beast, on average we see around 600 watts constantly, on not so windy days we see around 200 watts, ive seen our turbine put out as high as 2300 watts durning a storm, i love to sit and watch it, its kinda memorizing.
If you live on the side of a mountain that is going to cause turbulence and decrease power generation. We live on the top of a ~60' hill and our 2KW turbine is on an 85' Rohn tower. It does quite well. On days where we get 35~45 MPH winds it will produce 3.6KW. The tower gets it out of the majority of the turbulence so production is reasonably steady. I had a small 200 watt Winco about 45 years ago on a 25' tower and it would be searching for the wind almost constantly. That is a sure indication that the machine is in turbulence. It would race to maybe 10~15A then search back and forth while power generation dropped to just about zero. I put it on a 55' tower and it quit searching and stayed in one direction, hardly ever panning at all. Now it would pin the meter at 200+W and stay there. Probably 10X the power production as on the shorter tower. Back then our trees were about 10~15' tall.
Hmmm I’ve spent a small fortune on a fairly large set of these. $10,000aud. Can’t get them to charge properly for the past year. Just changed the inverter, another $5000aud thinking it was inverter now have same issue. Electricians doing the installation can’t seem to work it out. Never topped up in over a year as haven’t lost any liquids. Any suggestions?
you dont need to totally exchange the electrolyte its likely its either dried up or worse case air got in and CO2 caused carbonates to form which is reversible if you just crank up the voltage and add more water till eventually it will recondition itself.Not the most efficient way to do it but quite the nice bushfix.
Higher wind can also cause more turbulent airflow (mountain waves) I’m looking into getting a small turbine in a suburban location to backup solar and battery system. Thanks for your feedback 👍🏻👍🏻
One big problem with wind turbines is they will continue to send a charge to your battery after it's fully charged, unlike solar. Overcharging batteries can damage them and even cause fires, depending on the battery chemistry.
No, that's a problem with the DESIGN of the individual system. Anyone worth their salt, doesn't direct connect their wind genny to a battery bank. Like solar, wind should be put through a (reliable) charge controller. Where most people fail, is choosing a controller without a dump load. Dump loads allow the excess power generated, to be used to generate heat, inside say... a hot water tank. Less "wasted" energy, by using the waste to do something, like heat water. Danger only exists for the stupid and uneducated. ;)
Buenas tardes. Ese vaso que te falla esta en corto. Un separador se rompio. Se puede reparar. Pero te toca abrirla. Las otras se te han barnizado por la sobre carga. Posiblemente la potasa se incrusto. Piensa que evaporastes agua como loco la potasa tiene que ir algun sitio. Si estas en portugal España se puede comprar. Buscalo como koh o potasa caustica. Prueba a lavar los vasos con agua destilada varias veces. Saludos
It's a supplement to PV & hydro. If off grid it means that on windy night you may have the option of running appliances that you normally wouldn't, or that you get to still use essential stuff when weather is bad for a few days, not to be relied on for everyday living but a luxury item than may improve some miserable days.
Thank you for information ! Ilive in Latvija not far from the sea , and we have wind almost always something wind , but often very strong and impetuous. We have not so expensive electricity like you , but and income in proportion 😝 I study question about solar panels and wind turbines After your film , I know little more about this Thank you one more
Wind turbines need to be big to have any efficiency/economy of scale. Like 30+ storeys big. You just have to look at the market since 2020, all the major projects are massive. Wind is a centralizing technology whereas solar is decentralizing.

Mark 1.15 15 And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel. 2 Peter 3:9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance. Hebrews 11:6 6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him. Jesus
I live on a western shore of one of the great lakes, Unfortunately the wind blows from west to east, None the less I think im gonna try one maybe the new screw shaped one
*All practical tests show that small wind turbines hardly generate any electricity - and only at costs very significantly above 1€/kWh!* There is hardly any wind near the ground, and it is also very gusty, which extremely reduces the service life of the systems. *With solar systems, you can reliably generate electricity for about 3-10 cents/kWh over a period of 25 years!* // Alle Praxistest zeigen, dass Kleinwindanlagen kaum Strom erzeugen - und nur zu Kosten sehr deutlich über 1€/kWh! Denn bodennah weht kaum Wind, zudem extrem böig, was die Lebensdauer der Anlagen extrem verringert. Mit Solaranlagen hingegen erzeugt man zuverlässig über 25 Jahre Strom zu ca. 3-10 Cent/kWh!
