Review: Vertical axis wind turbine that is shy to produce more than 185 mA - Hello, I got this vertical axis wind turbine as a present from my better half. I have just tested it half-assembled, without blades attached; but I did attach the three radial arms for the ease of rotating the shaft by hand, and measured voltage and amperage produced. Here is what I discovered. It does actually generate some tens of volts easily, once I even managed to spin it so quickly that my multimeter registered 101.5 V on the MAX setting. Before that I got normal 12 V by rotating the shaft slowly with my fingers, and was kinda pleasantly surprised. However, don't get too excited about the high voltage yet, because there is one BIG CATCH - the supplied M10 three-phase alternator (motor-generator) which presumably is capable of producing 100W of power (max rating I suppose), appeared shy to produce more than 0.185 A (i.e. only 185 miliampers!), irrespective of how fast the shaft is rotated. In fact, I got 150-170 mA again easily at virtually any rate of rotation, but to reach the max registered 185.5 mA I had to work hard (as hard as for 101.5 V)... The moral is, this wind-turbine only looks powerful by the kinda "impressive" voltage figures but is very much powerless in all actuality, because electrical power (Watts) and, for that reason, energy (Watt-hours) is measured as the product of Volts and Ampers (in this case miliampers), i.e. in this case maximum we get is something like 100V*0.2A = 20 W, and this is *at best*. - Well, having my educational background in physics, I have all the reasons to doubt that it can produce max voltage at max current; the physics (electromagnetism and induction laws) simply won't allow this to happen - for a practical test, one can easily check that it's much more difficult to rotate the generator's shaft under any appreciable load demanding current (i.e. not just a voltmeter). Overall, I conclude that this wind-turbine must have been produced as a toy, may-be good for educational purposes (although considering its size I would doubt its usefulness even for that). It is a shame that the manufacturer advertises it as a proper "green energy" solution, claiming that this micro-turbine starts producing "power" in low wind. It only produces mostly useless voltage in any wind conditions, and it's only usable, perhaps, for occasional LED applications (in strong enough winds), where current must be well controlled and kept low. Forget about charging any serious battery or its contributing to a solar-battery array! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079QFYBB6 | | Customer Reviews | 2.0 2.0 out of 5 stars (1) | | Date First Available | 9 Feb. 2018 | | Item display height | 130 centimetres | | Item display length | 85 centimetres | | Item display weight | 12 Kilograms | | Item display width | 80 centimetres | | Item model number | SMART WIND | | Part number | SMART WIND | | Product Dimensions | 85 x 80 x 130 cm; 12 kg | ## Images ![Domestic mini micro vertical axis wind turbine generator SMART WIND 300/400 / 500 W savonius multi blades for home garden roof - Image 1](https://m.media-amazon.com/images/I/417+9oFLueL.jpg) ![Domestic mini micro vertical axis wind turbine generator SMART WIND 300/400 / 500 W savonius multi blades for home garden roof - Image 2](https://m.media-amazon.com/images/I/41g0Otmm1vL.jpg) ![Domestic mini micro vertical axis wind turbine generator SMART WIND 300/400 / 500 W savonius multi blades for home garden roof - Image 3](https://m.media-amazon.com/images/I/41nTsgnsscL.jpg) ![Domestic mini micro vertical axis wind turbine generator SMART WIND 300/400 / 500 W savonius multi blades for home garden roof - Image 4](https://m.media-amazon.com/images/I/41xad5VEY5L.jpg) ![Domestic mini micro vertical axis wind turbine generator SMART WIND 300/400 / 500 W savonius multi blades for home garden roof - Image 5](https://m.media-amazon.com/images/I/51-sDG-rFuL.jpg) ## Questions & Answers **Q: Why do you nead a bridge rectifier with this wind turbine** A: Below is the answer, but I would not bother about this so-called 'Smart wind' turbine as it produces no power at all (no more than 185 mA) - see my review. This is a 3 phase AC 'generator' so it produces alternating voltage/current (shifted in time) in the three wires sticking out of the motor. The AC should be converted to DC (constant voltage, direct current), whence the rectifier bridge, but beware - the provided diode bridge does not quite rectify to DC, it only combines the three AC waves to produce pulses of the same polarity. So one still needs to smooth the ripples with a filter, or at least a large capacitor. **Q: Would this be able to power a house in the UK?** A: No, house need 3KW **Q: Can this be used with a hybrid solar and wind hybrid controller (3 cables)** A: yes (check input voltage) **Q: What would be my best option for my house in Spain? Is it possible to go on the grid here etc .** A: You can buy option you need ## Customer Reviews ### ⭐⭐ Vertical axis wind turbine that is shy to produce more than 185 mA *by A***B on 18 November 2019* Hello, I got this vertical axis wind turbine as a present from my better half.
