5) Water-pumping Station;

Structure and component parts:

1. Generator Part
It is composed of the patented SCF generator, the nose cone, and the protection cover. Hummer adopts the state-of-the-art SCF supercritcial generator, which is installed in the hub, easy to radiate heat and reduce wind resistance. Made of high-efficiency magnetic materials, special copper alloy, high-strenghth stainless steel and aeronautic aluminum alloys, which is extremely light in weight and small in size, but with higer power producing efficicency.


2. SKF Bearings
Two SKF bearings ensure the reliability the longevity of our generator. Wide temperature ranges: Operation in the high temperature (150-350º C). Long life span, reach up to 60000-100000 hours. User may not change the bearing during the wind turbine using. It can greatly reduce the maintenance costs.

3. Flange & Blades
The flange is made of fine steel, used to fix the blades to the rotor. The blades are made of glass reinforced plastic, efficiently turn the wind energy into the mechanical energy. Every set of the three blades has passed the strict balance test before the shipping. It is important to fix the blades together which belongs to one set to the flange and never mix them up with other blades which belongs to another wind turbine.

4. Furling Mechanism
The mechanism is composed of the 360 degree rotation yaw shaft, the tail rod and the rudder blade, which are made of the manganese stell and aluminum alloy. It combines the high strength and the lightness and is able to react to the gusts rapidly.

5. Multi-function "3 in 1" Inverter Controller

Hummer "3 in 1" inverter as a multi-function controller is made especially for 500W and 1000W systems. It combines the functions such as rectifying AC into DC, charging the batteries, inverting DC to AC to power the electrical instruments, and dumping the extra energy which may overload and burn the system, thus protecting the whole system.

6. Off-grid Inverter & On-grid Inverter
Hummer off-grid inverter adopts SPWM (Sinusoidal Pulse Width Modulation) technology, is able to invert DC with higer efficiency into AC with stable frequency and voltage, filters the noise as well. It is used in the off-grid power system.
Hummer on-grid inverter adopts MPPT (Maximum Power Point Tracking) technology and IGBT (Insulated Gate Bipolar Transistor), is able to invert DC with a high power producing capacity and a wider AC voltage output range. It connects to the public grid and there is no need for any power storage device.

7. Rectifier/Dump Load Controller & Dump Load Box
The controller controls the process of which the alternative current produced by wind turbine into direct current and eventually charges the battery bank with DC. It also controls the switching on and off of the dump load to protect the system against the risk of being overloaded with too much power.
Metal box design of the dump load radiates the heat of the resistance inside quickly via the air convection. So there is no need for an extra fan.
