Bergey BWC XL.1

With a rotor diameter of 8.2 ft and a peak output of approximately 1,300 watts the XL.1 is intended for the off-grid home market in the U.S., telecommunication sites, and for rural electrification programs in developing countries. It is also a perfect upgrade system for current owners of solar-only off-grid systems.

Very quiet operation is achieved with advanced rotor design and an oversized alternator that reduces the rotor operating speed.

The BWC XL.1 is currently available only as a 24 VDC battery-charging system.

Recommended for:

  • Off grid sites
  • Telecom sites.
  • Rural elecrification programs.

The XL.1 is often used in conjunction with solar to provide more reliable year-round energy supply.

Installation

The XL.1 is offered with a tubular Tilt-up tower in heights from 60 ft to 100 ft.  These kits are easy to install and offer customers a complete "ready to install" kit.

Wind Speed Performance

Low wind speed performance is greatly enhanced by a low-end-boost circuit that optimally loads the wind turbine down to wind speeds as low as 5.6 mph (2.5 m/s). 

Combined with the new blade system, this circuitry allows the XL.1 to produce useful power more than 6,000 hours a year at a typical site. 

For reference, a typical solar system produces power 3,500 hours a year at a typical site.
