Bergey BWC Excel

The BWC EXCEL was introduced in 1983 and it has been installed at over 1,800 sites around the world.

In October 2008 the Excel-S was upgraded to a more efficient Powersync II inverter. In July 2009 the Excel turbine was upgraded with a more powerful alternator and longer blades. Performance has been improved by an average of 25%.

Recommened for:

• Large rural homes.
• Remote villages and facilities.
• Eco-tourism resorts.
• Larger telecommunication sites.

Connected to the grid, the BWC EXCEL can provide most of the electricity for an average total electric home at moderate wind sites.

Inverter

The all new Powersync II power processor (inverter) is the most advanced in the industry and it carries a full UL certification to the latest utility standards.

Installation

The BWC Excel is most often installed on a guyed lattice tower, which is available in heights of 60ft to 140ft.

Tilt up versions of these towers are available for sites without crane access.

Non-guyed lattice type towers and monopoles (tapered tubular) towers are also available to heights of 120 ft.
