Wind turbine 500W

Model: H2.7-500W
Hummer 500W wind turbine is designed for off-grid system which uses battery bank to store the power. It can drive resistive loads within 500W or 370W water pump etc inductive loads. 

Features: 
 
1. SCF Supercritical generator
Hummer wind generator adopts SCF supercritical technology which won a gold award in the 37th Salon Eureka in Brussels. This technology significantly reduces generator’s weight and size down to 25% to 30% of the traditional one, and the production efficiency is 25% to 30% higher. This ensures that the generator functions perfectly in small wind condition.  
 
 
 
2. SKF bearings
Hummer wind turbine adopts two SKF (Svenska Kullager Fabriken) bearings which are produced by the largest bearing manufacturer in the world, with the perfect internal geometric structure, known for its life-time endurance and reliable quality. Ordinary bearings need to be changed every two or three years, while SKF bearings can greatly reduce the maintenance costs on this matter.  
 
 
3. Low noise
The design of the rotor blade of Hummer wind turbine absorbs the highlights of the small aircraft’s airfoil, which is compliance with the aerodynamic standards. It provides a more aesthetic look and a higher efficiency and reduces the noise production as much as possible.
 
 
4. Double braking protection
Hummer 500W wind turbine adopts double braking protection system, which are the yawing mechanism and electromagnetic braking system to regulate the rotation of the wind turbine. It is safe and convenient to shut down the whole system both manually and automatically.
