The BWC EXCEL was introduced in 1983 and it has been installed at over 1,800 sites around the world. It is a modern 7 meter (23 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 BWC Excel is a ruggedly built turbine that comes with the longest warranty (10 years) in the industry.
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%. Also in July 2009 the warranty on the Excel wind turbine was increased to 10 years – the longest in the industry.
Battery charging BWC EXCEL’s can be supplied with outputs of 24, 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 are 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).
