Leading Edge Wind Chargers

Back to Top

Leading Edge LE-300 Wind generator

The LE-300 features a fully integrated 3-phase Permanent Magnet Generator (PMG) that uses the latest, most powerful neodymium iron boron magnet technology. This gives the LE-300 a very low cut-in speed allowing the turbine to generate power at low windspeeds, as well as delivering over 300w at higher windspeeds.

Designed and manufactured in the UK, the turbine blades are incredibly quiet, UV resistant and extremely tough. Of equal importance, is the LE300’s ability to run at high output during ‘big’ winds for prolonged periods as it is designed to run through even the highest winds.

  • Weight 5.5kg
  • 85watts @ 8m/s (18mph)
  • 250 watts at 28 MPH
  • 2 year warranty
  • 12v, 24v versions available

Comes complete with charge regulator DL300 and run/stop switch LE300

Rutland 914i wind charger

The well known Rutland Windcharger has undergone a power output uplift through the use of latest electronics technology.  The new style Rutland 914i  is the next generation of 910mm (3ft) diameter turbines from Marlec with an increase in power output of over 30% from the same compact blade size. 10knots the 914i produces over 17% more power than the 913 model and at 15knots this rises to a 38% increase in expected annual energy output.

Rutland FM910-4 furlmatic wind charger

The Furlmatic 910-4 shares the same power performance as the Rutland 913 but incorporates a "furling" tail system designed to orient the turbine at 90Degrees to the prevailing wind in wind speeds above 35mph (15m/s). This allows the turbine to slow down, continuing to produce power whilst reducing wear on the unit. Use in applications where windspeeds are frequently high and sustained over long periods.
