400W Wind Turbine is designed and made with people that want to install a wind turbine by themselves at home or a small office that is small enough to fit and generate sums of power. It also works on marines too.

Product Features  

• 400Watt System uses wind to generate power, run your appliances and electronics for house or boat.
• Low wind speed model. This model operates with wind speed as little as 5 mph.
• Portable lightweight design as only 17 pounds, and the dimension of rotor diameter itself as 4 feet.
• Built-in charger controller.
• Over-charge/Over-speed/Over-temperature automatic break protection.
• Connect with 12V battery directly. 
• Power meter and manual break switch included.
• "Do It Yourself" and Maintenance Free.

Specification

*For the 400W turbine that operates on 0-15V output voltage, we highly recommend using 12 AWG wire and maintaining a distance of 20m (66ft) between turbine and the battery. Using inappropriate wire gauge will result in a drastic increase in voltage.

**Please activate the brake manually when the wind speed exceeds 30 MPH (48 KMH).Thesurvival wind speed means the turbine can survive 110 MPH (180 KMH) when the brake is manually activated. Exceeding this stated wind speed will result in wind turbine failure and collapse.
