A: The hybrid wind generator system uses hybrid charge controller to consolidate both wind and solar together to charge the same bank of batteries. So the key equipment of the hybrid system is the hybrid charge controller. Besides of this, there is nothing different. So if you have a wind system or a solar system, you can purchase a hybrid charge controller to easily convert your system to a hybrid system instead of purchasing a hybrid system on the market which does not give you the power they claimed. You can also configure your system by purchasing a wind system from a trustworthy source and a hybrid charge controller together to make a powerful hybrid system instead of  purchasing a so called 500W hybrid system which only gives you 200W wind power. CMS Magnetics provide 2 KW hybrid charge controller to our customers. Please contact us for details. Q: Is the hybrid system on the market really generating the power they claimed? The wind power generated by the system is to the power of 3 of the blade sizes. The current hybrid systems we saw have very small blade size which at most can generate 200 W or even lower around 18mph range. Considering the wind speed in most locations is much lower than the rated wind speed, you can only get about 100 W. So this kind of system is so far just a toy instead of a wind power system. Q: How the blade size is related to the wind power? This is very good question and the answer to it will help you to screen out the untrustworthy vendors. We have known the wind power is to the power of 3 of the blade size. Unlike power curve which can be easily compromised by the unfaithful dealer but difficult to be verified by the normal users, the blade size is very easy to measure and verify. The following is a reference between the wind power and the blade size for the wind speed of 18mph. 500 W, the blade diameter needs to be 8.2 feet or up. 1000 W, the blade diameter needs to be 8.9 feet or up. 2000 W, the blade diameter needs to be 10.5 feet or up So for a hybrid system has a diameter of 4.6 feet, you can only get about 200W of wind power at 18mph. But since most of places has a wind speed slower than 11 mph, you might only get 100 W or even lower. So how this kind of system is useful to you? How the dealer claim it as "500W Wind Generator System" and saying they are trustworthy? But you may argue that you have high wind speed like 28 mph. You need be even more careful since that small system may not be able to handle that kind of power at all.  The system either stops before reaching that speed or burn itself up after contiguous running for hours at that speed.  Q: How to decide if a system good for me or not? There are several factors to consider in choosing a right wind system. The first thing is to find out the average wind speed in your area. If your wind speed is lower than 4 meter per second (8.9mph), there is no need to look further since there is no system so far can generate fair amount of power at that wind speed. But if you wind speed is over 4 meter per second, you still need to ask a copy of the power curve of the system from the vendor. The power curve shows how much power the system will generate at various wind speed. So based on the average wind speed in your area, you will be able to know how much power the system will generate. There is a quite of bit systems or companies on the market do not provide the power curves or their nominal wind speeds which cause a big pitfall in the small wind market. Don't be fooled by the rated power provided by vendors but be sure to ask the rated wind speed for that power.  Q: Is braking system for speed control more reliable than the tail furling? The most reliable and cost effective speed control system for small wind is still tail furling since there is no electronic system involved in the controlling mechanism. The braking system normally is used for 3KW system or above. Using brake to control the systems under 3KW is rarely seen on the market since it's not cost effective. On the other hand, if a small system uses the braking system and selling price is low, you should have something to worry about since there is no justification between the low cost and high reliability for this complex braking system. The simpler the better is always right in designing products. So is the wind system. Q: Why the PowerMax products are right for me? The PowerMax wind generators are proven to work great for years. The system design is very effective. The systems have been installed in Europe, China for years. They are also appearing in the North American market since last year. Place a Bid!
