Wind energy can be used as kinetic energy to provide rotation of the wind turbine blades generating electrical current. This electrical current is referred to as variable 3-phase alternating current (a/c). This variable a/c is converted to direct current (d/c) by using various rectifiers. It is fed back into a grid-tie inverter converting it into a/c single-phase electrical power. It is then synchronized with the incoming grid (incoming electricity from power company) as the power is being used in a residential or commercial facility. The wind turbine/wind mill system can be used with battery charging banks for back-up power for homes. Some also use wind turbines to boost the performance of solar systems. Clean energy from the wind eliminates pollution and the by-product of these systems is spinning the utility meter backwards (reducing kilowatt usage and saving the customer money).

CWE-FRE -- FEATURES

1. The controller includes a dump load rated for twice the kw capacity and uses the latest technology (PWM) Pulse Width Modulation.
2. Generator uses Neodymium (iron-boron) permanent magnets.
3. Generator incorporates slip-ring technology with replaceable 15-20-year life brushes, eliminating the problem of cable twisting.
4. Units have 3-braking systems.  Plus additional manual brake on 10kw & 20kw units
5. Blades are special reinforced fiber glass with dense fill of poly-urethane and are designed for low noise.
6. All parts are electrostatic powder coated and hardware is stainless steel.

Competition (moving parts that can fail):

• Servos that can fail due to high torque imposed on them, trying to furl in high winds.
• Use dog-vane and anemometers that are inexpensive (plastic) and can cause Failure.
• Controller circuit boards are non-adjustable and are prone to Failure.
• Only one braking system (dump load). Should it fail the blades would over spin causing complete destruction of the unit.
