Max output of a 400 watt wind turbine generator

Here I tell you how to find the Max amount of watts that any wind turbine generator will produce before you purchase one. I purchased a 400 watt wind turbine. Before I bought this I already knew that this model would only output 240 watts Max on a great windy day Nowhere near the 400 watts that they say it would produce. The total cost for me to install this will end up being somewhere between $350.00 and $400.00. Do not fall for the listings where they say that a wind generator will produce 1200 up to 3000 watts because it's complete BS.
