Model: H4.**3kW 

Hummer 3kW wind turbine can be applied in both on-grid and off-grid systems. It outputs single-phase or three-phase AC and can drive a load below 3kW. 

1. SCF Supercritical generator 

Hummer's wind generator adopts SCF supercritical technology which won a gold award in the *7th Salon Eureka in Brussels. This technology significantly reduces generator's weight and size down to *0% to *0% of the traditional one, and the production efficiency is *0% to *0% 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. PLC integrated with Siemens module 

Hummer wind turbine's controlling system adopts the smart touch-screen PLC (Programmable Logic Controller) which is integrated with Siemens controlling unit. The PLC will alarm and adjust the abnormal running status of the wind turbine automatically both timely and efficiently. Siemens module offers high reliability to our PLC and its customers worldwide can testify for that. 

4. 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. 

5. Triple braking protection 

Hummer wind turbine generally adopts the yawing system and the electromagnetic braking system to regulate the rotation of the wind turbine. Besides, customer can order the hydraulic braking system as well as a third protection. It is easy and convenient to shut down the whole system both manually and automatically.
