ARI Wind Generators – reliable wind muscle
ARI Renewable Energy Company makes the most advanced hybrid solar-wind generator in an easy package. We have partnered with an American University to design and improve small wind energy technology. And our goal is to make the least expensive and highest quality solar-wind energy generator. We have developed industry leading technology for quietness, high performance, durability, and more efficient turbine blades for our generators. Our innovative wind energy technology is patent-pending for “Quietness and High Performance Turbine Design”.
Quiet Hybrid Energy Turbines
ARI energy turbines feature CPU controlled magneto generators for over-speed protection and higher efficiency at all wind speeds with simultaneously lower blade speeds, making it known as the quietest hybrid energy turbine among its competitors. This advanced technology for wind generators is the same as that used for regenerative braking on modern electric cars. Wind energy turbine generators provide power to a hybrid solar-wind charge controller with 12, 24, and 48 volt auto-regulating states to ensure optimal charging power of solar-wind and to protect battery bank from over charging. These technologies offer outstanding performance and efficiency that is the least expensive on the market with products of 500 watt, 750 watt, and others under development.
Customers report that the ARI system still operates at – 5.8°F and under severe icing conditions, while its competitors have frozen up and stopped generating power. Customers attest that our wind power generators do not create irritating howling or moaning noises or blade vibration due to high winds, as can be found with other turbines. Its unique design helps to create a beautiful skyline while providing clean energy on sunny or windy days.
Since solar power and wind power can complement each other as energy sources, a hybrid solar-wind power system will optimize the use of these two natural energy resources for needed power supply. Manufacturing costs of hybrid systems can be reduced because the same battery banks and inverter can be used for both the solar and the wind generators.
Advanced Over-Speed Protection System
As the technology of small wind generators has advanced in past decades, so has the industry. However, the reliability of small wind generator continues to plague the industry. Due to cost considerations, manufacturers tend to use mechanical controllers, which are based on simple principles of aerodynamics, for wind power control, in lieu of the more technologically advanced and more expensive hydraulic pressure controller. While it could pass wind turbine tests, a mechanical controller, which has movable parts, does not work well in the field due to the complexity and rapidity of change in wind speed and wind direction. The
movable mechanical parts invariably wear out in extreme weather conditions, resulting in a break down of the system.
Since fewer movable parts give less chance for a breakdown, high-quality wind generators today typically have only three movable parts:
Main body of wind turbine
ARI’s wind turbine blades are made of fiberglass reinforced composite and are shaped through a high-precision casting process. Fiberglass is an extremely strong material that also has the advantage of stability and quiet operation. Fiberglass can endure severe weather and environments, such as storms and exposure to salt water and heat. Fiberglass itself is heat resistant and corrosion resistant. The material is used in the ship industry in boat frames, in Olympic sports as pool material, in the construction industry as support pillars for mansions, and as high-quality blades for wind turbines. Due to its high intensity strength, heat resistance, and corrosion resistance, fiberglass is a good choice for propeller materials for the hybrid solar wind generator system. ARI rotor blades are meticulously designed by experts in aerodynamics to have very low startup and incision points and very high wind energy utilizing ratio. Because of the aerodynamic quality of the blades, propeller racing can be avoided in all circumstances.
The ARI wind alternator is made with high quality, high strength permanent magnetic materials. It is lightweight and compact with high power generating capacity. Our wind alternator experts have used unique electromagnetic technology that results in very little starting resistance, thus effectively guaranteeing the easy startup of the ARI wind turbine even with gentle breezes. And ARI alternator is designed to provide efficient DC power with an electronic control system. The power capacity and startup performance have made this alternator one of the best alternators in the world.
The ARI turbine’s main body is made of high-quality die cast aluminum alloy from a precision casting process and from stainless steel components. Thus it is lightweight yet extremely strong and has high reliability. Because of the precision casting process, ARI wind turbine has a perfect shape. Moreover, the die cast aluminum alloy can work as a cooling system for the turbine, because it transfers heat into wind passing through the turbine. Furthermore, the ARI wind turbine is easy to install and maintenance-free. Its unique design will help create a beautiful skyline while providing clean energy for you in sunny or windy weather.
– Over-speed protection system
The first two movable parts are indispensable because they compose the core of the wind turbine. In order to increase reliability, we must turn our attention to the over-speed protection system.
All wind turbines are designed with some kind of over-speed protection system. In case of strong wind, it is necessary to waste part of the excess energy of the wind in order to avoid damaging the wind turbine.
There are two different ways to design an over-speed protection system on modern wind turbines.
A pitch-controlled wind turbine that turns blades out of the wind when the wind output becomes too high and turns them back into the wind when the wind speed drops.
A stall-controlled wind turbine that has blades bolted onto the hub at a fixed angle. When the wind speed becomes too high, it creates turbulence on the side of the blades that is not facing the wind. This stall prevents the lifting force of the rotor blade from acting on the rotor.
However, both approaches have technical problems. Wind flow is a complex phenomenon. Not only is turbulence a constant occurrence, but the change of wind speed and direction is instantaneous and frequent. No mechanical apparatus can react swiftly enough to match the instant change in wind flow. As a result, the heavy wear and tear often causes the breakdown of the wind turbine.
ARI Renewable Energy Company has developed a brand new electromagnetic brake for ARI wind turbines. The new technology incorporates an entirely new magnetoelectricity regulator that functions as a brake.
This brand-new regulating protection idea has discarded the mechanical regulation structure and has fundamentally solved the reliable operational problem associated with the hybrid solar-wind generator.
This advanced over-speed protection system has following advantages:
It has discarded the mechanical regulating structure and the wind turbine, and therefore it only retains two moving parts. This greatly enhances the structural stability and reliability of the ARI wind turbine.
The design of the main body of the wind turbine now has more artistic and diverse choices when the mechanical regulating structure is limited.
The advanced over-speed protection system also gives different levels of charge control according to the wind speed scope, which greatly increases the reliability of the ARI wind turbines.
– Charge Controller
The surface of the ARI solar wind charge controller is made through a precision casting process with high quality and die cast oxidized-processed aluminum alloy plate. On the outside of the controller is a digital monitor that visually displays the process of charging and discharging the battery. A solar charging LED and a wind charging LED are displayed separately on the monitor. When solar power is charging the battery banks, the solar LED lights up, and when the wind power is charging the battery banks, the wind charging LED lights up.
The ARI charge controller is designed with the feature of over-speed protection to give the ARI wind turbine maximum safety and reliability. Moreover, the charge controller has a circuit breaker installed to avoid accidental short circuit of the battery. Furthermore, the ARI charge controller is also designed with a voltage regulator that monitors and regulates the battery voltage. When the battery voltage rises above the set point, the CPU automatically shuts off the turbine and the rotor blades stop rotating. As a result, the wind turbine stops generating power. When the CPU senses a voltage drop, the wind turbine resumes rotating and begins normal charging of the battery.
