Living Off Grid

Rutland FM1803-2 Furlmatic Windcharger

Where grid power is not available the FM1803-2 provides a cost effective solution, charging batteries to deliver 12/24V power which can also be inverted to 230V AC. The FM1803-2 can deliver sufficient power for most daily needs with only occasional use of a generator for high energy consuming appliances, e.g. domestic washing machine. Where a generator is already used the FM1803-2 will soon reduce energy costs and pay for itself in convenience. Direct fuel costs and engine wear and running time will be noticeably reduced.

Rutland FM1803-2 Furlmatic Windcharger

Includes MPC1 Controller

The Rutland 1803 comes with the MPC1 Controller which protects batteries against overcharge. A digital LED display shows battery voltage  switching points are automatically adjusted for ambient  temperature to maintain optimum battery performance.

MPC1 Controller incorporates 4 key features; 3 phase trasnformer to reduce voltage, a rectifier to convert AC to DC an electronic controller and battery overcharge protection.

  • The FM1803-2 Furlmatic Windcharger with its robust 3-bladed wind turbine is supplied with it’s purpose designed controller.
  • New 3 bladed turbine design combines an efficient profile with a durable injection moulded construction.
  • The 3 phase generator has a very low torque enabling power generation to start from just 3m/s (<7mph) windspeed.
  • Rutland unique disc type brushless generator design has a high degree of inertia that keeps the turbine spinning between gusts of wind where other designs stop and start. As such the FM1803-2 delivers more power into a battery.
  • Sliprings at the tower top allow the turbine freedom to find the wind over 360q rotation.
  • AC power is generated and transmitted to the controller. As the AC is generated at high voltage power losses are low allowing small cable to be used, minimising installation costs.
  • Marlec’s well established furling tail system is used on the FM1803-2. The tail normally directs the turbine into wind but a simple gravity induced mechanism operates at 15m/s (35mph) to push the turbine off wind thus reducing it’s speed. This provides protection from the forces exerted on the turbine and tower in very high winds and assures longevity of the product.
  • MPC1 Controller incorporates 4 key features; 3 phase transformer to reduce voltage, a rectifier to convert AC to DC an electronic controller and battery overcharge protection.
