3. Identification

Each BWC XL.1-24 wind turbine has a serial
number decal located on the support structure
inside the nacelle. Since this label is only accessi-
ble by removing the nacelle it has been noted on
the Warranty Registration form. We recommend
writing it here as well.
BWC XL.1-24 Serial No.:
Each PowerCenter has a serial number decal af-
fixed to its side casing. This number has been
noted on the Warranty Registration form. We
recommend writing it here as well.
BWC PC.1-24 Serial No.:

4. System Description

XL.1 Wind Turbine Components
The major components of the XL.1 wind turbine
are shown in Figure 2.
A. Blades / Rotor System
The rotor system consists of three fiberglass
blades. Acting like aircraft wings, the blades con-
vert the energy of the wind into rotational forces
that can drive a generator. The airfoil on the XL.1
is the new SH3045 developed specifically for the
XL.1 by Bergey Windpower. The fiberglass
blades are exceptionally strong because they are
densely packed with glass reinforcing fibers that
run the full length of the blade. The rotor has three
blades because three blades will run much
smoother than rotors with two blades.

B. Alternator
The alternator converts the rotational energy of
the rotor into electricity. The alternator utilizes
permanent magnets and has an inverted configu-
ration in that the outside housing (magnet can)
rotates, while the internal windings and central
shaft are stationary. The alternator was specially
designed for the XL.1 and produces power at low
speeds, eliminating the need for a speed-
increasing gearbox.
The output from the alternator is three-phase al-
ternating current (AC), but it is rectified to direct
current inside the nacelle. Since it uses perma-
nent magnets, the alternator is generating voltage
whenever the rotor is turning.
Warning
The output wiring of the BWC XL.1-
24 presents a low voltage shock haz-
ard whenever the rotor is turning.
Caution must be exercised at all
times to avoid electrical shock.
