Unfortunately, i bought 500 watt chinese turbines from Anhui Hummer..
i have to tell you that their Technical Parameters are completly fictional..
They claim their 500 watt turbine can produce up to 1000 watt .. But in reality it is not.. Maksimum power i can see was 600 watt with 15 m/sec wind speed.
They claim their noise level is good. But,It is the noisiest turbine in the world.
They claim the design life is 20 years.. But their blades are broken within 2 months. They told me that they change their blade suppliers, so i ordered new blades. But Now their generator is burnt

company is telling me that, my average wind speed is to high. (it is only 7m/sec yearly) .
i want to sue Anhui Hummer Wind Turbine because of making wind turbines that can not withstand avarega wind speed of 7 m/sec !!.
is it possible to sue them in China?
are they still in business? i search for wind turbine forums.. There were a lot of problems reported worldwide... Does anybody else that cheated like me in this forum..
