Zephyr Airdolphin Mark-Zero 24 VDC 1000-watt charger

Zephyr combines advanced wind turbine technology with Japan's world-renowned manufacturing craftsmanship, to successfully develop the Airdolphin wind turbine - a next-generation, lowmass
wind turbine which instantly adapts to changing wind conditions, from slight to stormy.

- The core rotor has three ultra-light carbon fibre blades, embossed to dramatically reduce air flow noise.
- Programmed to automatically rotate 10 seconds per minute in low wind 
conditions, to kick-start rotation.
- The robust body and power generation unit can produce power at up to 50m/s 
wind speed, which is more than double speed of other existing systems.

The total weight of the Airdolphin is 17.5 kg (38.5 lbs). Unlike larger turbines, the Airdolphin’s low mass allows it to be mounted on existing structures like remote telecommunication towers, transmission line pylons and billboards, as well as near roads, railways and airports. Even factory and urban rooftops can become cost effective locations for producing usable electrical power.

The blades of each Airdolphin are created with Zephyr’s patented SD blade technology (noise reduction ridges). Their designers were inspired by the feather patterns of owl wings, which allow owls to ly in silence. This technology applies a series of thin ridges to the surface of each blade, creating micro vortices to keep the airlow attached to the airfoil longer than conventional blades, thus reducing decibel count.

By realizing constant blade rotation speed, operation of the wind turbine has been made much more silent and secure. Their original and patented technology maintains uniform rotor spinning speeds
while encountering turbulent gusts found in cities or raging winds at remote locations. These attributes are crucial for small wind turbines because they are often installed in cities where turbulence is caused by tall buildings. When the wind speed increases beyond 20 m/s (44.7 mph), the Airdolphin continues delivering output power at a reduced rpm eliminating the need for cut-out entirely. The intelligent power management system inside the turbine achieves its outstanding performance by software driven microprocessors including control irmware, an internal battery charge controller monitoring voltage and charging rates in a variety of climatic conditions, a web interface, and data logging functions.

All units come with a 5-year warranty.

24-volt and 48-volt battery charging models have built in charge controllers. The grid-tie GTO has a 250 VDC output and requires a separate grid tie inverter. Zephyr recommends using an SMA 3000US  or 4000US inverter for grid ti applications. All turbines mount on a 1.5 inch Schedule 40 pipe. Maximum pipe diameter is 1-15/16 inches.
