Re: need advices for a hy1000 wind turbine please help me
Hi Mertin, welcome to the forum.
For others who may be interested, here is a link to the turbine description, photos etc: http://hyenergy.en.made-in-china.com/product/seCQtDZHAohx/China-1000W-Wind-Turbine-HY-1000L-24V-.html
Now to my answer I wish it could be different
Mertin, I regret to say, I once had a similar turbine with similar blades, and it never ever produced the "rated" power. In fact, the only time it ever produced any useful power here in Nouvelle-Écosse, was when tropical storms came up the East Coast and hit us. During those times the blades would scream like an insane vampire and the turbine, rated for 1000 watts, would actually put out less than 250 watts. With "normal" wind, it would sometimes put out 10 watts, but mostly it just looked pretty, spinning against a clear blue sky. I took it down after 2 years and switched to solar panels, as the turbine was really useless and there was a real fear of the blades self-destructing during a tropical storm and I was afraid the United States would fire a rocket at me when the blades from my turbine entered their air space at very high speed.
All was not lost though, I saved the alternator and have used it with a small water powered turbine for about 5 years. I gave away the blades, tail etc.
Unfortunately small wind turbines are mostly a scam to get our money.
Salut Mertin, bienvenue sur le forum.
Pour d'autres qui pourraient être intéressés, voici un lien vers la description de la turbine, des photos etc: http://hyenergy.en.made-in-china.com/product/seCQtDZHAohx/China-1000W-Wind-Turbine-HY-1000L-24V-.html
Maintenant, pour ma réponse que je souhaite, il pourrait être différente:
Mertin, j'ai le regret de dire, j'ai eu une fois une turbine semblable avec des lames semblables, et il jamais produit le "classé" puissance. En fait, la seule fois où il jamais produit aucune puissance utile ici en Nouvelle-Écosse, a été quand les tempêtes tropicales sont venus de la côte Est et nous ont frappés. Pendant ces périodes les pales auraient crier comme un vampire fou et la turbine, classé depuis 1000 watts, serait effectivement mis sur moins de 250 watts. Avec le vent "normal", il fallait parfois mettre à 10 watts, mais surtout il avait l'air assez juste, la filature contre un ciel bleu clair. Je l'ai pris au bout de 2 ans, et passé à des panneaux solaires, que la turbine était vraiment inutile et il y avait une crainte réelle de l'autodestruction lames au cours d'une tempête tropicale et j'avais peur des États-Unis serait tirer une roquette sur moi lorsque le lames de mon turbine sont entrés dans leur espace aérien à très grande vitesse.
Tout n'était pas perdu cependant, j'ai sauvé l'alternateur et l'ont utilisé avec une petite eau turbine pendant environ 5 ans. J'ai donné les lames, etc queue
Malheureusement petites éoliennes sont la plupart du temps une arnaque pour récupérer notre argent.

Re: Generator on the fritz
Aw c'mon. 300 hp cars for $500. Gas for .19 cents. Homes for $15,000 - much less in rural areas. Halter tops and micro minis. Batteries for $12. Concert tickets for $5. Utility companies were eager to supply power to remote locales.
But yea - solar has improved at least 10 fold.

Re: Designing my off-grid system without starting with load
It's rare but I pretty much disagree with all the advice Mike has given...
Solar panels aren't likely to produce more current than the panel is capable of and are generously rated. You 320 watt panel that generates at STC, little less than 9 amps normally will have a 15 or 20 amp fuse rating. Even in a warm/hot environment they aren't likely to blow unless you have and even that they are protecting you from. I haven't had one blow in the 12 years of using them.
That said, I think I will built my own combiner box next time around with a NEMA box, as I've picked up a couple a section of din rail and use Midnite's or other din rail breakers. THIS WILL NOT MEET CODE! I think NEC code is no touch now, where you can't have exposed electrical anywhere. My previous fuse type combiner box met code in the past, but I believe this has been recently changed so that no exposed connections are allowed in the combiner box.
I've got no problems with suggesting a 48 volt system if you can find a reliable inverter charger in your price range. I, and many others, don't find Aims reliable. You can search the forum here for past problems with Aims inverters.mike95490 said:bluepigfarm said:.... I will buy batteries locally (leaning toward's 8 Trojan 105's in two strings for 24v). ......Then bite the bullet and go to a 48V system Aims makes a 48V , 2Kw inverter charger with 30A transfer switch
I like to recommend the Morningstar inverters for campers, they are good reliable units but have somewhat limited features. Be aware that the Midnite has fans, as do most others from Outback and Schnieder etc, but they have a lot of features that allow the user to start and use loads when they batteries are approaching full and a battery monitor that allows measuring the current actually flowing into and out of the battery.mike95490 said:Midnight Classic has 3 cooling fans, they make a fair amount of noise - Morningstar MPPT-60 is silent
Most systems have a combiner box at the array and a breaker at the power center in front of the charge controller. Once you throw the breaker at the power center, you have no power going through the fuses and can safely remove them or check and replace them.mike95490 said:Combiner box, you really want to use breakers, because the brand midnight sells are switch rated. If you use fuses, you cannot break an energized circuit, you have to wait till sun goes down. first or 2nd fuse that blows, you are in the price range of breakers

I certainly hope we never meet. Never come to SW Arizona in the winter. I'm there. With my lithium batteries and high-grade Black Domina.Horsefly said:I think I'll stay here and know that @OldMan won't be. Sounds like we both will be better for it.

Re: Wildfires are nice for Solar Business
In a sense, state/local are 100% funded. They just have to take your 401k & that's the funding problem solved!

Thanks for the information, he is another Australian, lives on the opposite side of the continent. Looks like he installed his LFP battery in December 2012 about four months before I installed mine. Impressive that he has been off-grid since 1991.

If you went to the outback tech forum and pm gorden Lunbaunm.

Re: Choosing a good generator
My belief is the best generator is no generator other than the solar system. Let ol' Sol do the warming and when it gets cold, move to a warmer location. Only fuel used is the gas to get you to a warmer location. I haven't one single clue why people want to live where it's cold. Masochists, I suppose.
What about a solar system? Gensets are for Tyrannosaurus Rex and its relatives.Ralph Day said:Re: Choosing a good generator
First a question. Why would you need more than you can get from a 2kw inv genset? That's what I'd go for if my 10kw diesel died completely on me.
Natural gas...you can't store it, if supply is interrupted you're somthing out of luck. As you said, Gasoline it is.
What about a larger inv genset, Honda goes up to 5kw for your shop loads and charging.
