Bergey Wind Turbines

The BWC EXCEL is a modern 6.7 meter (22 ft) diameter, 10,000W wind turbine designed for high reliability,
low maintenance, and automatic operation in adverse weather conditions. It is available in two
configurations: battery charging and grid-connected (the pumping version is not currently available). The
BWC Excel is a ruggedly built turbine that comes with the longest warranty (5 years) in the industry.
Battery charging BWC EXCEL's can be supplied with outputs of 48, 120 or 240 VDC. They are well suited for
large rural homes, remote villages and facilities, eco-tourism resorts, and larger telecommunications sites.
Connected to the grid, the BWC EXCEL can provide most of the electricity for an average total electric
home at moderate wind sites. The all new GridTek 10 power processor (inverter) is the most advanced in
the industry and it carries a full UL certification to the latest utility standards.
The BWC EXCEL is most often installed on a guyed lattice tower, which is available in heights of 18 m (60 ft.)
to 43 m (140 ft.). 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 37 m (120 ft).
The BWC EXCEL was introduced in 1983 and it has been installed at over 900 sites around the world.
