Wind Solar Hybrid Off-Grid System
1. System Introduction Nowadays in modern society, electric power is an essential resource to our life. However, due to various reasons and conditions, there are still quite a lot places in the world have electric problem. In this case, this wind solar hybrid off-grid system can effectively solve this problem of electric shortage, and also with unique advantages.
2. System Theory Wind turbine and solar panels generate electric, charge into battery group through controller, the system supplies power through inverter in AC for lights, home appliances, electric tools and other load.
3. Applied RangeVillage, farm, island with electric shortage problem.

6. System Advantage
- High efficiency, more profit!
- High performance Off-Grid controller and inverte
- Safety, steady, long service life!
- Low Working Noise!
- Easy installation!
- Easy maintainence!
6.1. High efficiency, more profit!
This system has our patented Pitch-Controlled wind turbine, which can output 30% more electricity than normal wind turbine. Pitch-Controlled wind turbine has the following advantages,
(1) Lower start up wind speed!
Pitch controlled wind turbine blades have the best start up angle, can be started up with 2.5m/s wind speed. Best wind power availability when the wind speed is lower then rated wind speed.
(2) Stable running when wind speed is higher than rated wind speed
When then wind speed is higher than rated wind speed, secondary regulation starts up to make sure system have a stable output power.
Lower start up wind speed, then increase the rotating speed, then have a stable output power with a higher wind speed to make sure there is a 30% more electricity output.
6.2. High performance On-Grid controller and inverter
After years research and practice, we have developed high performance On-Grid controller and inverter, which are more suitable with the Pitch-Controlled wind turbine. Each unit of the system can work perfectly, so the system could output more power, and has a longer service life.
6.3. Safety, steady, long service life!
(1) Leading centrifugal pitch controlled technology world-wide.
Exactly regulation: Information input source of pitch controlled mechanism is wind rotor rotating speed. System regulation is more stable, reliable and quick response and so on.
Softness regulation: Impact caused by wind speed becoming will be decreased through the pitch controlled mechanism. Regulation soft, failure rate low
Longer service life: System adopts mechanical part, floating connection, smaller fraction losses, less failure sources, better environment adaptability, Longer Service life.
(2) ASP System (Automatic safety protection system)
ASP system, our patent product is unique protection system in China. It can control the wind turbine to run or stop by testing the environment wind speed and system working voltage. When the environment wind speed or system voltage is over the set value, it will shut up the wind turbine. When the wind speed is lower than 25m/s, it will release the brake system, wind turbine restart to work. ASP makes nobody guard come true
6.4. Low Working Noise!
Excellent permanent magnet power technology and aerodynamic characteristics of the blades, lower the noise level of the wind turbine. The noise level is less than 65dB.
6.5. Easy installation!
(1) Easy to installation without any heavy equipment likes crane, save installation cost.
(2) Carry and installation are not limited by landform, especially for mountain area and island
(3) Tilt-up tower, easy to install and maintenance.
6.6. Easy maintainence!
(1) Remote monitoring and control service is available, you can learn real-time running status of the wind turbine and read the output power data effectively. The remote monitoring APP for mobile phone can be available soon.
(2) Tilt-up tower, easy to install and maintenance.
