You need to go really big to make it reliable in an off grid situation.
its not about peak power but what you get at 8-10 MPH, which is usually not a lot. Unless you live in a good wind area, solar is cheaper and more reliable. The only upside to wind is possible night time production.
They have some serious drawbacks. Basically lightning rods and they require a significant upfront additional cost to make them work efficiently.
A direct to battery hook up with a dump load is only viable at 48 volts, maybe 24 volts if its small wind turbine but that kind of defeats the purpose. Even in three phase the low voltage would mean very expensive and thick wire and the dump loads would not match up to the wind turbine perfectly, so you end up with micro cycling. Only a handful of MPPT controllers support wind, I only know of one, the midnite classic and all require some sort of voltage sensing brake that switches the three phase over to a resistor bank to slow it down if the voltage gets to high, such as entering float in a wind storm. Midnite makes a clipper for that but its over 1200 dollars. So nearly 2 grand to make it charge the batteries correctly and efficiently. Doesn't make much sense for the common sub 600 dollar wind turbine with a 6 ft diameter turbine. Usually rated at some ridiculous speed and wattage you will never see.
The way I see it the only way to do wind in a way thats reliable and will charge your batteries is go big. Either a bergey wind turbine or a DIY wind turbine with a 10-12 ft blade diameter. You can make a more than half decent one out old truck parts. Brakes, rotors etc. Scorag Wind has a book on it. Pretty well thought out that includes how to make an axial flux pma. Something well suited for the low rpm.
Personally I would go with a LOT of blades. While it lowers the high speed performance, it helps in low speeds as long as the PMA is wired to take advantage of the extra torque. An example would be old style water windmills. Terrible at making power, which is true but in low speeds you will find more consistent performance. Something you might value over a high once a year output. A high torque windmill. A actual mechanical speed governor is a must. Relying on dump loads or electrical resistance along is a bad time.
Any one form of control or stopping is not enough. Just my .00002 adjusted for inflation. This is based off a lot of research, I do not own a windmill or wind turbine and probably never will. Solar is just so cheap.
