The Rutland 503 Windcharger
Free and abundant wind power keeps your batteries topped up and ready to start….

Rutland Windchargers simply convert the free and abundant power in the wind to power stored in your batteries. The 12V power is ready to use for engine starting, lights, coolers, essential navigation equipment and other low energy appliances. With a Rutland 503 installed on board weekend sailors will experience the convenience of fully charged batteries for engine starting.

Rutland Windchargers are a popular sight in marinas, thousands are in use worldwide and boat owners like their particularly quiet operation coupled with clean, aerodynamic lines. Without doubt the unique Rutland alternator design accumulates more energy than any other comparable wind generators available and you'll always see a Rutland spinning in the lightest of breezes!

The Rutland 503 model’s “safety turbine” makes it ideal for trickle charging on board where space is at a premium. Weekend yachts and sailboats up to 10m benefit from it\’s compact size and charging capacity in particular where batteries up to 100 Ah are in regular use.

Motor home and touring caravan owners will find the Rutland 503 conveniently portable and ideal for topping up the battery when parked.

When you fit a Rutland Windcharger on board you will experience:

  • Direct savings on fuel costs and engine maintenance owing to reduced engine running time
  • Security of power for essential appliances on-board, eg. navigation equipment
  • Fully charged batteries for engine starting on returning to your boat. ……and don\’t forget that by keeping your battery trickle charged its life will be extended too!

    Rutland 503 Windchargers are also found on:

    Features & Benefits

  • Efficient power conversion – Rutland Windchargers generate greater ampere- hours in real wind conditions than turbines of equal and often larger diameter! That’s because between gusts, our unique high inertia alternator designs maintain momentum with a flywheel effect where other units stall. This adds up to more free power generated and stored for you.
  • Rutland Windchargers provide the lowest cost per watt of power generated.
  • The low friction 3-phase alternator gives a smooth and silent output. The low wind speed start up means power is almost continuously produced and certainly in the most typical conditions as well as being powerful in higher winds.
  • Rutland 503 turbines are made from computer designed efficient aerofoil blades whose tips are joined by an outer protective ring.
  • No radiated interference. Complies with EEC Directive 89/336/EEC

  • Rutland Windchargers are renowned fo their quiet and continuous operation
