Product Details
Place of Origin: | Anhui, China | Brand Name: | Hummer | Model Number: | H9.0-20kW |
Type: | Wind Power Generator |
Product Description
1. SCF Supercritical generator
Hummer 20kW wind turbine 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 20% to 30% of the traditional one, and the production efficiency is 10% to 30% higher. This ensures that the generator functions perfectly in small wind condition.
Hummer 20kW wind turbine generator 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 control
Hummer 20kW wind turbine generator 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 20kW wind turbine generator 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. High reliability
Hummer 20kW wind turbine generator 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.

HUMMER's scientific researching team is composed of experts who have got special government approval support. With SCF (the technology won Gold Award in the 37th World Invention Exposition in Brussels Eureka) supercritical generator technology as its technical core, we have researched and developed our own HUMMER brand wind power generators, including 7 patents and independent intellectual property rights as well as light weight structure,small size and high efficiency.
Not only we devote ourselves to the research of generator technology, but to the improvement of the whole system’s stability, safety and reliability. Siemens CPU is adopted for control system,and metal dumping resistor for unloading system.Some high-performance materials and parts are adopted, such as SKF bearings. We strictly follow the ISO9001 quality management system. HUMMER wind energy turbine system has passed European CE certificate and Hummer generator has passed American UL certificate.

Q: What are your advantages?
A: Hummer has its own scientific research team which is composed of experts who have got special government allowance support. With SCF generator supercritical technology as the core, we have developed Hummer wind turbines, and got sixteen patents. We adopt Siemens PLC and touch screen for Hummer control system, as well as SKF bearings for high quality Hummer wind turbines.
Q: Do you have any certificates?
A: Hummer company has passed ISO:9001 Certification while wind turbine system has passed CE and UL certificate.
Q: How many types of the wind turbines do we have?
A: Hummer wind turbine generators ranges from 500w to 100kw including 400w,500w,600w,1kw,2kw,3kw,5kw,10kw,20kw,30kw,40kw,50kw,60kw,100kw. We now have Off-Grid wind turbine and Grid-Tied wind turbine system together with the controller, inverter,rectifier,dumping load and tower etc.
Q: What types of tower's do you offer?
A: Hummer offers Guyed Wire, Free standing tower, and hydraulic tower.
Q: What type of warranty comes with a Hummer wind turbine?
A: All Hummer wind turbine come with a standard 2 Year Limited Warranty for generator system and all other parts 1 Year Limited Warranty.
Q: How reliable are wind turbines? Will I have to perform much maintenance?
A: Most small turbines have very few moving parts and do not require any regular maintenance. They are designed for a long life (up to 20 years) and operate completely automatically.
Q: Don't I have to take wind measurements for a year or more?
A: For most residential systems the cost of taking wind measurements is not justified. Wind resource data published by the U.S. Department of Energy is sufficient for an experienced evaluator to predict wind turbine performance. In very hilly or mountainous areas, however, it may be best to collect wind data before purchasing a system to ensure that your site is not in a sheltered area.
Q: What shall we do if there are some problems that clients can’t deal with?
A: Our 20kw/30kw/40kw/50kw/60kw/100kw wind turbines have PLC controller, we have Siemens PLC control system with the touch screen control system which allow for remote monitoring and solving the problems.
Q: How would I have a wind turbine installed at my home?
A:Hummer offers a complete Turn-Key (ready-to-operate) system. We have licensed and qualified technicians who will complete the install for you.
Q: What type of generator does Hummer manufacture?
A: All Hummer wind generators are three-phase, permanent-magnetic alternators with slip-ring.
Q: Can you explain the high power yields and efficiency of your turbines versus your competitors?
A: Hummer small wind turbines are permanent magnetic generators located in the hub of the turbine, forward of the blades. Our turbines have large wind swept areas and are direct drive, not gear driven. Our turbine generators operate at 80% to 85% efficiency and the engineering and design of our turbine technology is state of the art.
Q: How quiet are the Hummer wind turbines?
A: Hummer wind turbines are very quiet. The Noise db(A) range from the 500 Watt to the 20kW is 29 db(A) to 34 db(A).
Q: What benefits do your SCF Generators provide and how does that differentiate your turbine technology from others?
Q: Do the Hummer wind turbines use any type of braking system?
A: Yes. When the wind turbine needs to shut down manually for maintenance or the controller senses a problem (such as extreme wind speed), the wind turbine is rotated parallel to the wind to bring the blades to a very slow spin. The PLC controller then causes an automatic circuit override which uses the permanent magnets within the generator to bring the blades to a complete stop.
Q: Can your small wind turbines be remotely monitored?
A: Yes. Our Grid-Tied turbines come with PC software that can be monitored from anywhere around the globe as long as there is an internet connection available.
Q: Do you have an irrigation system available for your turbines?
A: Yes. Hummer turbines can be set up as an Off Grid system to power water irrigation systems.
Q: Are your turbines solar compatible?
A: Yes. Hummer developed wind solar hybrid system fulfill wind-solar applications.
Q: What type of maintenance do you recommend on your turbines?
A: On sizes 500W to 2kW, there is no maintenance required on the turbine itself. On the 3kW and higher we recommend lubing the yaw shaft acme screw once per year. We recommend on all models to check the guy wires (guyed towers) or connection bolts (freestanding towers and hydraulic towers) once a year to make sure they remain tight.
Q: On your Grid Tied system, if the power grid goes down, do you have any protection built into your system?
A: Yes, we have a built in unloading system that cuts off power to the grid and is fully automated.
Q: What type of protection do your wind turbines have for high wind speed?
A: When the Anemometer measures a wind speed in excess of 65 mph, the controls will turn the wind turbine 30° out of the wind to regulate speed. If the blades are still rotating too fast the controls will turn the wind turbine a full 90° and shut down. It will then monitor wind speed every 10 minutes and decide if it is ok to start back up or stay shut down.
Q: Can Hummer wind turbines be setup with a back up diesel generator in an Off Grid set up?
A: Yes. Using an ATS (automatic transfer switch) a diesel generator can be set up to automatically switch on when the wind turbine is not producing enough electricity.
Q: Are your turbines harmful to the environment and birds or other wildlife?
A: Our turbines are not harmful to the environment, in fact they greatly help to reduce dependent on other forms of energy that are harmful to the environment such as fossil fuels. There is less of a chance of a bird being harmed by a wind turbine than that of a fossil fuel burning jet liner taking off on a runway.
