The Leading Edge Wind Turbine LE-450 is the most powerful
compact wind turbine with a 1m rotor diameter and designed to provide
meaningful power levels at everyday wind speeds of 5-8m/s (11-18mph) while
tough and robust enough to withstand storm force winds. The Leading Edge
LE-450 wind turbine is a quiet, powerful and lightweight 450W wind turbine for
battery charging and grid connected applications. Fully optimised for marine
conditions, the LE-450 is ideal for supplementing the power supply on-board a
sailboat or yacht and provide energy when solar PV panels are unable to
operate effectively such as during winter or overnight.
Manufactured in the Britain to a high standard, the LE-450 wind
turbine is extremely easy to integrate with solar panels to create small scale
off-grid renewable energy systems for powering security, telecommunications,
lighting, signage, telemetry and off-shore applications. Available in 12V, 24V
and 48V for battery charging applications the LE-450 wind turbine can also be
grid connected.

Powerful in every day winds
The LE-450 generates the same power output as other small wind
turbines with blades up to 1.2m long, making it the most powerful wind turbine
for its size. The turbine is designed around a unique low inertia axial flux
generator which uses Neodymium rare earth magnetic materials. This alternator
has zero ‘cogging’ allowing the turbine to spin in the lightest of breezes and
to react quickly to gusts.
Its excellent power production stems from an exceptionally low
start-up wind speed and superior transfer of power from the wind in every day
winds of 5-8m/s (11-18mph). This is achieved using 5 blades and by fine
tuning the alternator to extract the right amount of torque, at the right RPM.
Small & lightweight
The LE-450 wind turbine has a uniquely designed aluminium alloy
chassis that not only gives an overall turbine weight of just 8kg, but ensures
responsive reaction to gusty winds. The turbine’s small operating envelope at
just 1043mm enables the turbine to be installed in locations where space is at
a premium – on yachts, telecoms towers and CCTV stations. The wind generator
is fitted with integrated yaw slip-rings that allow it to swivel 360 degrees
in order to follow the changing direction of the wind.
Rugged & reliable
The LE-450 wind turbine is designed and manufactured to be as
rugged as possible giving a predicted design life of 20 years – with little
maintenance required during that period! The LE-450 survives destructive high
winds by means of a simple passive aerodynamic design that limits turbine RPM
and power output at wind speeds of 20m/s (45mph).
The LE-450 wind turbine is manufactured from high
quality aluminium alloys and stainless steel which has been laser processed,
CNC machined, hard anodized and powder coated to ensure that the turbine
withstands the harsh effects of the marine environments. The fixings are
manufactured from A4 stainless steel that can survive the harshest of
environments. The Timkin bearings are contain low temperature grease for
optimum performance down to -40degC.
