Yet I felt confused again and had to do a little reading to clarify what I thought I knew…of which I know little about the subject and still have a fair bit to learn. But what the website says and what you are saying is incongruent, so I wanted to reply to see if I’m missing something here and not understanding what I think it is that I am reading about. Or, if what I think I know, about what I am reading, is accurate.
1 - The webpages on the different types of cores offered, say this…
[i]Use these powerful permanent magnet alternators (PMA/PMG's) to make cheap
more blades has been shown to consistently produce more power throughout the year.
I could still learn quite a bit more about the number of blades, but here’s my simple basic understanding of it.…”which may be wrong?” More blades produce more energy in low average winds, and they rotate slower so there is less chance of sending a surge of energy through the core and frying it. Less blades allow for higher rpm, and they also work better in higher wind speed areas. For low average winds, more blades has been shown to consistently produce more power throughout the year.
I don’t see any mention anywhere of the turbine being designed for category 4-5 winds? But, it does say that it is designed for low/medium wind speeds. The 340 watts at 13mph seems like an accurate prediction, which is great for me, my PV array is only 600w….off grid. I know they advertise the peak wattage, as all the different small turbines I’ve seen seem to do the same, so I know that it’s only going to produce a fraction of that in the average winds of my area.
If I’m far from understanding what I think I know, then please illuminate my path and show me something better. I’ve looked at the whisper 200 in the past as was mentioned above, it has a couple of things that I like about it more, built in tilt and variable voltage output, but at nearly 3 times the cost?? Is it really that much better? If I’m going to put in the time, effort, and money, then I want it to last, so I’m open to learning.
