Review of Home Wind Turbine Generator 5-Blade 500W Max/12V - Low Wind Model

I purchased this WindMax system several months ago so I have had time to see how it works. When there is enough wind it works GREAT BUT in low wind conditions it actually drains power from the batteries. When it is at a stand still it does not drain the power. For instance, my solar panels had my batteries full and it was dumping into the loader when a slow wind came up and immediatly stopped the dumping. Within four hours my batteries had lost all the gains made by the solar panels and then some! I'm not sure if the diodes are bad or if it is a design flaw or what but it isn't a good thing. I'm not sure how to fix this or even if it can be fixed. I have brought this to the attention of the company with no response. So if you have a constant wind that is strong enough to keep it at its' cut in speed or above I would recomend it. Also the tail fin fights with the blades for control so I added an extention (more surface area) to it and solved the problem. It now has no problem with staying faced into the wind.

Product Description:
Advantages of 5-blade wind turbines over 3-blade wind turbines1) 5-blade wind turbines will greatly improve annual energy production in low wind conditions. For areas with average wind speeds of 11 MPH (5m/s). If you compare annual energy output to conventional 3-blade wind turbine, there is an increase of annual energy output of more than 60%.2) 5-blade wind turbines will dramatically improve the reliability and safety in high speed wind conditions. The blade rotation speed of a 5-blade turbine is 60% of the rotational speed for a 3-blade wind turbine. 5-blade wind turbines will greatly reduce chance of overspeed control malfunction. This will ensure operational reliability from a long term perspective.3) The lower blade rotation speed of 5-blade wind turbine will lower wind turbine noise and make 5-blade wind turbines more community friendly than 3-blade wind turbines.Nylon-Fiber Glass High Efficiency blades is aerodynamically designed to regulate themselves, slowing automatically in high winds. 1. Strong Neodymium magnet PMA, the unique winding and multi pole design reduces the start-up torque of the alternator that assures generator to generate electricity at low wind speed. 4.5 mph start up wind speed.2. Electric over-speed control, no more problematic mechanical furling.3. Innovative low maintenance two-moving-part system design.4. Easy to Install, Light Weight and highly reliable.5. Generator: The generator is built using high-performance rare earth neodymium permanent magnets, so the alternator is compact and light weight with a high power generating efficiency. It is designed for various working conditions such as severe climate, sand and salt corrosive environments and marine usage.Number of Blades: 5Blade Diameter: 4.6 FeetRated 400W @26 mphMore Energy Output at low wind than 3-blade modelsMax Wind Output: 500W
