LE 300W (12V or 24V) Wind Turbine
The LE-300 Extreme is small direct drive microturbine
designed for use in many difficult and
demanding applications. Its aesthetic low profile
design, coupled with its unparalleled low wind
regime performance and low rotor acoustics make
this turbine the ideal choice - whatever your
application - from electric fencing to C02
abatement or off-grid homes.
The LE-300 Extreme features a fully integrated 3-
phase Permanent Magnet Generator (PMG) that
takes advantage of the latest, most powerful
neodymium iron boron magnet technology. This
configuration gives the PMG excellent low RPM
characteristics with a very low cut-in speed allowing
the turbine to spend more time generating power.
The uniquely designed and manufactured turbine
blades work in harmony with the PMG to allow the
turbine to operate at low wind speeds, low RPM
and with low acoustic emissions. Of equal
importance, is the lE300's ability to run at high
output during 'big' winds for prolonged periods - it
is protected by a high-speed thermal cut-out which
prevents the turbine over-heating in constant, very
high winds.
This means that a LE-300 Extreme will generate
more kWhs in an averagewind regime -compared to
competitor products that are 'rated' at an
unrealistic 12m/s (27mph). In optimum conditions,
with an averagewind speed of just 5 m/s (l1mph), a
single LE-300 Extreme could generate as much as
40kWh per month of free and clean renewable
energy. That represents a C02 abatement of 18kgs
per month.
The innovative and versatile micro-turbine designed
for superior performance at low wind speeds.
LE-300 Extreme features:
- low TSR rotor blades with excellent low wind speed performance, and exceptionally low acoustic emissions.
- Rotor blades are injection moulded for excellent consistency.
- Rated at just 8m/s for superb low wind speed performance.
- Proprietary low inertia axial flux generator using Neodymium Iron Boron magnets.
- Our unique iron less generator design has no 'cogging', which allows effortless start up in low winds and reduces 'generator hum'.
- The 3-phase output from the generator is rectified onboard for a DC output.
- CNC machined components throughout.
- Constructed from powder coated / anodized aluminium and stainless steel.
- Aesthetically pleasing and low visibility profile.
- Oversized tail fin for excellent response to turbulent wind conditions.
- Designed to run through severe weather conditions.
- Unique bearing configuration resulting in low friction, low bearing noise.
- All bearings a lubricated and sealed for life.
- Anti-vibration fixings used throughout.
- All-up weight of just 5.5kg.
