how to install vertical arbor wind turbines (wind generators) www.carbonfreeenergy.cn
Silent Wind Turbine . The Vertical Axis Wind-Power Turbine ( VAWT ) is a new product designed . We started the research on VAWT 15 years ago. Now many of the famous experts the world wide have accepted such new technology and this technology will definitely lead the development of the small and middle size wind-power turbines. Following are the detail features of such VAWT: Safe in operation: Due to the usage of the vertical blade and the force support is of triangle form, the wind force will mainly press on the wheel. So the blades will not be able to fall down, to be broken or to be thrown far away. Noise: The way of the turning of the blades is of horizontal and the design of the blade is of the scheme of the wing of the air-plane, so in operation the VAWT will not make any noise. Capacity of wind resistance: Due to the advantage of the design of the VAWT, the press force the turbine suffered is minimized and as the result such VAWT can stand on the extra strong typhoon of 45 m/s. Space requirement: It needs much smaller working space than other kinds of wind-power turbines. Thus not only saves the space, but also aises the working efficiency. Power curve: It needs lower wind speed for its starting and the increasing of the power is slow and stable. So its production capacity is 10-30% higher than other kinds of turbines. Scope of the wind power needed: Due to the adoption of the new control system, this VAWT is suitable to be used in the wind speed scope from 2.0 25 m ...

Solar Chargers For a Bright Future
Solar energy is a form of renewable resources to feed our energy consumption. Energy from the sun is derived through radioactivity on the sun's surface that reaches the earth. The sun's energy is used to do a lot of things in our modern world. The common use of solar energy is to convert it to thermal energy for the purpose of heating such as water heating for homes, buildings, swimming pools or Jacuzzis. Thermal energy is also used for heating spaces like the inside of a greenhouse, homes as well as buildings- commercial or residential.
Apart from heating, solar energy is also used to be converted into electricity through solar chargers such as photovoltaic devices. These devices convert sunlight directly into electricity and are often used in areas that are not accessible to the electric grid. Solar energy can be changed into electricity through solar power plants. These solar chargers indirectly generate electricity from solar thermal collectors.
Solar chargers are built centered around maximizing the potential of the sun's energy and thus, it serves a multitude of benefits to both the consumer and the environment. As a household unit, you can do your part in saving God's green earth by reducing your green house emissions by installing solar water heaters. Not only do you reduce green house gases, you also reduce your monthly electricity bills.
Solar water heaters offer low cost heating and are also low in maintenance costs. Hot water is generated 24 hours per day and is designed to operate in a wide range of weather conditions. So even if it's a cold or cloudy weather, these applications can extract heat energy. Solar water heaters reduce carbon dioxide emissions by generating hot water from the ambient air (as low as -10°C) and can heat water to +70°C.
When solar lighting is used at home, not only is it energy efficient, is also requires minimum installation and minimum wiring is needed- this is what makes solar lighting have a low cost on installation. Solar lighting also gives you big savings from State and Federal taxes and is of course, environmentally friendly.
When talking about solar energy and solar products, think long term in not just reducing cost. Solar energy also increases a certain aspect of your home- the real estate value. By installing solar devices and gadgets, you increase the value of your home and it is also a good investment for you towards a sustainable future. Not only that, you gain energy independence- no more relying on local power supply incase it breaks down or if there is a shortage. Solar chargers are not only found in home appliances, but in smaller capacities such as watches, batteries, calculators, fans as well as cooking appliances and cameras, mobile phones and iPods, even cars. With solar charges becoming increasingly popular, you will find, in no time, practically everyone and every industry will start using these devices as more people find out the importance of saving the environment, conserving energy and saving the planet.

Ensupra grid tie power inverter can obtain the solar energy from solar panel, and can tie to the grid through its output cable with no extra equipment. The installation is Do-It-Your Self (DIY).When the sun shines, the PV panel will produces DC voltage, and the grid tie inverter will change the DC voltage to AC voltage and puts out power to the home grid, saving electricity. INSTALLATION: 1, Connect the Solar Panel or Wind Turbine s DC supply cables to the DC input terminal of the inverter, be sure that the polarity is correct. Recommended DC input cable size for maximum output is 12AWG or cables that can handle more than 15A. Optimal length would be less than 8m, longer cables will experience higher voltage drop. The range of output power of Solar Panel or Wind Turbine is 50W~600W. 2, Connect the supplied AC power cord to the inverter and plug it to a home wall socket. 3, The green LED indicators will glow when the grid and DC supply is detected. This indicates the inverter is operating under normal condition. The red LED will be on, the inverter will not put out power, this is called Island Protection.Please follow local regulatory electrical codes for installation. If in doubt, consult appropriate licensed contractor.Electrical Specifications: Maximum AC Output Power: 550W AC Output Voltage Range: 120V ±10% AC Output Frequency Range: 60±3Hz Total Harmonic Distortion(THD): <5% Power Factor: 0.96+ DC Input Voltage Range: 25-46VdcPeak Inverter Efficiency : 90% Standby Power consumption: <0.5W Output Current Waveform: Pure Sine-wave Over Current Protection: Yes Over Temperature Protection: Yes Reverse Polarity Protection: Yes Island Protection: Yes Stackable : YesWARRANTY: 1 YEAR----IMPORTANT NOTE: OUR SHIPMENT TIME FOR THIS TYPE OF INVERTER IS TWO WEEKS.
