Rutland FM910-4 Furlmatic Wind Charger 12V - Land Based

The FM910-4 Furlmatic is without doubt the engineer’s choice of micro wind turbine for battery charging at off grid locations. Countless organisations worldwide have installed tens of thousands of Furlmatics because, simply, their reliability in the toughest weather conditions is so well proven.

Rutland wind turbines are contructed using a range of modern and traditional high quality materials which are designed to endure even in a marine environment. They are innovative in their field as they introduced light weight but robust high density nylon and glass reinforced materials that are UV stable alongside marine grade aluminium, stainless steel, sealed for life bearings and other carefully selected and precision worked materials in a UK factory.

The Rutland FM910-4 combines our proven furling tail system and latest 3 phase generator technology with a new aerodynamically shaped body style. This combination of the established and the modern means that our customers can be sure of great power performance and reliability over many years service. Primarily designed for land based applications, the Rutland Furlmatic has been used worldwide to provide year round power generation. in a UK factory.

Technical Features & Benefits?

  • Efficient Power Converstion
  • More ampere hours are generated because of the Rutlands’ low wind speeds
    start up (of just 2.6 m/s) so power is being generated in the most typical wind
    speeds as well as being powerful in the strong winds.

  • Rutland Windchargers generate greater ampere hours in real wind conditions
    than turbines of equal and often larger diameter! This is because othe unique
    high inertia alternator designs maintain momentum between gusts unlike
    other designs that stall and have to rebuild up speed.  This Rutland “flywheel”
    action results in more free power generated into your battery.

  • Automatic ‘furling’ tail fin directs turbine out of wind above 16 m/s for gale
  • Low friction 3 phase alternators give a smooth and silent output.
  • Computer designed efficient aerofoil blades. The fine profile blades have a
    positive one-way-only fit that have been tested to withstand a loading with a
    safety factor 10 times the turbine’s maximum rpm.
  • EEC directive 89/336/EEC compliance ensures no radiated interference.
  • Automatic thermostat protection in prolonged gales.
  • Modern, durable materials for excellent reliability and product longevity.

Wind & Solar Energy are free and abundant sources of energy so once fitted you can let nature do the work while you enjoy the free power!
