BERGEY XL/R 7.5 kw WIND ENERGY SYSTEM (off grid)

Bergey XL/R 7.5 kw Wind Energy System (off grid):
This off grid Bergey XL/R 7.5 kw Wind Energy System is a 6.7 meter (22 ft) diameter three-blade upwind turbine which achieves high reliability through rugged construction and a minimum of moving parts. The EXCEL wind turbine series is nominally rated at 10 kw. In a battery charging application, however, there is an inherent load matching problem between permanent magnet alternators and battery banks. The EXCEL-R is optimized for low wind speed performance, which maximizes energy production. However, providing the best performance in low winds results in some reduction in peak power under high wind conditions. Therefore, the EXCEL-R is rated at 7.5 kw.

Enhanced Corrosion Protection for the EXCEL is provided at no extra charge on all Turbines. Hot-dip galvanizing (in the case of the mainframe, tower adapter, and tail boom), zinc electro-plating, and polyurethane paint systems all provide exceptional protection from corrosive environments. Fiberglass Reinforced Pultruded (FRP) components (such as the blades) are protected by ultraviolet-inhibiting resin additives and sub-surface "scrim cloth" UV barrier. The blades have polyurethane leading edge tape for protection against erosion. The VCS-10 controller, which comes with the EXCEL-R wind turbine, provides controlled rectification through a three-phase semi-converter.

The semi-converter uses phase modulation to control charging voltage and current based upon the battery bank voltage. Safe operation of the EXCEL turbine is independent of the load conditions, allowing the controller to unload the turbine during regulation. No auxiliary load is required. The VCS-10 is fully solid-state and is passively cooled (except for 24 and 48 VDC versions). It incorporates an LCD display of DC bus voltage and status lights to indicate the charging mode of the unit.
