Wind Generator Price Grid Connect Controller For Wind Turbine Driven Induction Generator (async Motor)?

Grid connect Controller for wind turbine driven induction generator (async motor)? - wind generator price

We thank you, lots of helpful answers to my questions above, I found a company that sells a product. It should be remembered, was intrigued by this device: http://www.clariantechnologies.com/main/page_home.html. It is a motorized vertical axis wind turbine, which as an asynchronous induction generator, which has a direct connection to an electrical outlet in your house. N investors without batteries. Price about 500 €. With a meter (a free product from our Power Company), which can work in reverse, allows me to significantly reduce my electricity bill, all at a very low cost. To make the price even cheaper, and increase the performance, asynchronous I have my own wind, and with my own. So all I need is the driver.

I have a company that sells such a device: $ http://www.prairieturbines.com for 830th Connects up to 5500 watts wind-driven induction motor directly to the network. No investor without batteries. There used to increase a "life" for the measurement of RPM, which provides about 1 AMP for the motor, their roles, solid-state 50AmpZero cross relay, capacitors, 30Amp or switch box, a disconnect mounted on the outside and mount in the molten voltage control switch. That's it!

So my question is anyone know how to build this driver. This company does not sell plans for them, and $ 830 is too high for me. I'm sure I could build with the components for less than $ 400. If a person of electrical engineering, which can help, it will be a challenge, but it's great to know that someone noticed this and it is for sale.
