Light :
Hummer-the smallest bird in the world, the heaviest of which weighs 20g and the lightest 2g.
Humme-350W Wind Generator Weights only 5kg, 15kg for 1KW, and 25kg for 2KW (including blades, hub and nose cone).
Small :
Humme-as small as a wasp, is the smallest bird in the world.
Hummer Generator-small in size: motors are all covered by nose cone.Low energy consumption, low noise, low rated wind speed(6.5m/s for 350W)
Hummer-Small-sized Wind Generator System is commended as generator-invisible system.
Swift :
Hummer-flutters its wings 50 to 200times/s, it is the most swift fluttering of wings for all birds in the world.
Hummer-Swift Start-up: Hummer Small-sized Wind Generator can start as swift as a bird. With wind speed at 2m/s, it will start surely. While conventional wind generator is waiting for higher wind to start up,Our Hummer has been working already, tranfoming wind power to electricity.
Hummer-Swift rotation, high effieciency and low resistant-torque, Hummer Generator runs 1.5 to 3 times faster than other types of generators under coequal condition. So the energy transformed rate is high, and can produce more power.
Hummer-Swift charge: Due to high efficiency and low wind start-up, Hummer's running time will be longer, of cause it can charge battery faster than other wind generators.
Stable :
Hummer-is a flying expert,it can freely fly, hover, suddenly stop or turn.
Hummer-Small-sized Wind Generator System is compact and light; its blades adopt end joint and can fly stably.
Hummer-Small-sized Wind Generator System provide perfect protection for overcharging, overdischarging, short circuit, overloading, over heating, etc.; its charging, inverting and unloading,etc.
Hummer-LED display, as to be easily read. And buzzing alarm has enhanced the system's stability and reliability. ----------------
