Q: Are you manufacturer or trading company of wind energy generators?
A: Factory. Anhui Hummer Dynamo Co., Ltd. is a famous high and new tech enterprise which is specialized in R&D and the production of wind turbines. With 11 million RMB registered capital,the company covers an area of 7.5 acres, a cradle for independent research, development, production and sales.
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 control system, as well as SKF bearings for high quality Hummer wind turbines.Hummer wind turbines are direct-drive permanet magent synchronized alternator(outer rotor),no gearbox,users can choose remote control & monitoring touch-screen,hydraulic brake system,as well as ultrasonic dogvane/anemometer.
Q: How many types of the wind turbines do we have?
A: We now produce off-grid inverter wind turbine and grid-tied inverter wind turbine.Our wind turbines include 500w,1kw,2kw,3kw,5kw,10kw,20kw,30kw,40kw,50kw,60kw,100kw,200kw together with the controller,inverter and tower etc.We also have wind-solar hybrid energy system,including 400w,600w streetlight system.
Q: What types of tower's do you offer?
A: Hummer offers guyed tower, freestanding 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: Do 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: 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: What shall we do if there are some problems that clients can’t deal with?
A: Our 5kw/10kw/20kw/30kw/40kw/50kw/60kw/100kw/200kw wind turbines have PLC control system, which can remote monitor to solve the problems.
Q: How do wind turbines perform as an investment?
A:The wind system will usually recoup its investment through utility savings within six to 15 years and after that the electricity it produces will be virtually free. Over the long term, a wind turbine is a good investment because a well-sited wind system increases property value, similar to any other home improvement. Many people buy wind systems in preparation for their retirement because they don't want to be subject to unpredictable increases in utility rates.
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: 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.
