Thanks for sharing. I learned that ratchet straps may help. May need to hinge on some concrete anchor.
This looks like a job for one of those cheap Chinese pipe benders. If you put an identical bend in all 3 pipes, just below the blade length, you could splay them out in 3 directions and create a more stable triangular base. Then, you weld cross pieces at the bottom between the legs. If you drill holes in all 3 legs in parallel and put 2 of them through 2 of the legs, you can use them as a hinge to raise it. You can also pull it by the top leg when it is at a low angle. This is how large radio towers are designed.
Thanks for the advice, much appreciated. Working on a solution this week.
I have a 32ft mast which is 2" scaffold. I built a gin pole and use a electric winch both make this very easy to raise and lower the turbine when needed. I think I 'd up the cable as well if that's an i1500 at 24v it can deliver 55amp.
Good luck and have fun
Nice setup, would love an electric winch. Thanks for sharing and the advice, planning on upgrading the cable at the first maintenance take down.
I was thinking of the following solution. I might use it at some stage for myself, but never tried. Currently, your centre of rotation is the ground level. So, the wait has to be lifted, with a centre of rotation at around 6 m away. The related force is proportional to the weight * 6 m --> quite high value. To reduce the issue, I was thinking of putting the centre of rotation 1.5 m or 2 m away from the ground level. that way, you reduce the force to let say something proportional to 4 m and you can use the 2 m on the other side with some weight (cement, stone, body weight etc.) to counter balance the force. The rotation should be quite easier. To use such solution, you will have to build a small wood structure to lift the centre of rotation up. Good luck!
Exactly what I was thinking. Use a counterweight. You are 100% correct. Now Have to get more steel to build it and figure out the design. Coincidentally the tower with generator weighs 75kg, roughly the same weight as a person 😉
*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 (as here ....).
Only if you need to be self-sufficient from the power grid, you should have the largest possible wind turbine for the winter on a high mast.
*With solar modules, on the other hand, you can reliably generate green electricity for 25 years at approx. 3-10 cent/kWh!*
Thanks for the sales pitch there Michael, if you're a genuine viewer you will be able to see from our other vids that we also use solar and are well informed in both solar and wind technology. Thanks
I think the hinge is too narrow, should be about a 250mm wide. Keep going, very entertaining video.
Mine was almost as bad ; I ordered a 24 volts model but they sent a 12v. instead. So I'm using it anyways on half the battery bank. I ordered five more blades too, and a hub, for a different one. Mine has been up twelve days.
Sorry to hear they sent you the wrong one, that's a pain. How's it performing for you?
We have ours up now, and will have a video about it coming out on Friday.
Hi,
related to the potential water issue inside the turbine (Many video referencing the issue). I have contacted support to ask if a hole needed to be drilled to evacuate the water. This is the answer they gave me: 'it's important to note that the video you provided is from 5 years ago and does not represent the current version of our turbines.
We take the issue of water resistance seriously, especially considering the climate in Ireland.Also, our turbines do include aluminum in their construction as well. Rest assured that we have made significant improvements in our latest turbine models to address any previous water-related concerns. Our new turbines are designed to withstand various weather conditions, including rain, ensuring reliable performance in the Irish climate.
There is no need to drill a hole to evacuate potential water inside the turbine'
Related to the dump load been a bit small for the turbine power: I have put a smaller copper wire with higher resistance. The power dissipated by the wire is R * I * I. So, when the wind is average high, no major loses because the intensity is not that high. For huge storm (P > 1500 W), I is very high and I square very very high. Hopefully the high resistance cable will dissipate the extra power for P > 1500 W. (And the cable is much less expensive)

Hello Jean Paul. Thank you for posting the results of your enquiry, interesting to hear istabreezes response. Let's hope the current models are updated as they say. The first takedown for maintenance will reveal all and I plan on publishing a vid on this when the time comes.
In regards to the dump load:
Originally I had planned on including one in the system however, after the storm force 10 winds we had a few weeks ago which took down a few turbines across the UK, I discovered that it's safer to apply the brake and not allow the turbine to spin up in extreme conditions. As the blades spin fast it presents the entire area of the rotating circle to the wind effectively like a giant sail putting enormous strain on the turbine collar and mast. With the brake applied only the narrow area of each blade is presented allowing extreme winds to simply pass through causing no damage at all. The downside is no generation during these periods, the upside is increasing the life span of the device and reducing maintenance requirements.
Might be worth considering with your turbine.
In regard to the thinner wire, I'm curious about heat dissipation and fire risk and eventual failure of the wire as this would act like a fuse and eventually break under severe load. Are you using a heat sink to dissipate the heat or what way have you got it set up?
Put a gin pole at the bottom for leverage. Will make this far easier. I have a customer that bought a 100' pole tower that comes with a gin pole from Bergey. It goes up without any trouble with a small boat type worm gear drive winch powered by an electric drill.
Also, the pole you have is on is way too short already. The turbine will be plagued by turbulence which robs the turbine of the ability to make power out of scattered winds.
He needs more than just a gin pole ...
Gin pole is missing
Yes, a gin pole is one way to counter balance the load however we have got it up now with an alternative to a gin pole. Tune in Friday to see how we did it.
If You get 40A on cpc, the 2.5mm2 earthing of the cable, it will overheat
The cables are 6mm2.
Im regisyered sparky. You should use 4x3 or 6x3 cable or 3 single core 6mm2 min.
@@robertoleszek8361 thanks, the 6mm2 twin and earth is rated for 50amps.
Ok you will learn hard way
@@robertoleszek8361 24v at 1600w =66amps. The turbine may never produce that. If it ever does then I can switch the wiring from the solar panels which is 10mm2 twin and earth. Run the solar on the 6mm2 and the turbine on the 10mm2. As a mechanic and former BMW technician I'm fairly up to speed on the wiring side of things. Thanks for your suggestions all the same, much appreciated 👍
I felt your pain!
Yep, lots of language had to be left out of that vid 🤣🤣🤣
You don't need 5 blade setup for anything. It is worse than 3 blades in any way and cost more.
Sorry but that's totally incorrect. 3 blades are only efficient at large heights (100ft) or more where there is more consistant single directional airflow. 5blades works better here because the mast is lower and winds are squally and change direction quickly. Perhaps a bit of research into different setups and the different environments they're suited to would be of benefit to you.
5lopat w ista nie daje zbyt duzo.tyle ze turbina startuje wcześniej.moc produkowana tez drastycznie spada bo wolniej sie kreci.
?
Translation result
5 shovels in ista doesn't give much. It's just that the turbine starts earlier. The power produced also drastically because it spins more slowly.
(Google translate)?
@@ourkilkennyhomestead2006 you bought an iste with 5 propellers. 5 the propeller turns slower and the power of this turbine drops drastically.
@@RaddiM3 thanks for translating and thanks for watching the vid. Yes we went for the 5 blade model as the perform better in lower windspeeds. We have made more videos on its performance which might interest you.
How many quid is a sandwich
I see what you did there 😁
i saw your video i am from istabreeze tell me what you need i will give you a spare part for free.
Thank you for your kind offer but the replacement parts have already arrived.
Never buy chinese stuff! Be inteligent!
Believe it or not Sam, Chinese parts are in many non Chinese products, particularly electronics.
