Rutland Furlmatic 1803 WIND GENERATOR
The FM1803 is another product technological advancement engineered by Marlec. It follows the great success achieved with the original Rutland Furlmatic FM1800 which has established a proven track record of reliability in a variety of applications from the cold, harsh environment of Antarctica to the hot, dusty climate of the Sahara Desert. 

The Furlmatic 1803 is Marlec's largest power unit incorporating 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 on land based applications where windspeeds are frequently high and sustained over long periods.
Below you will see the performance specification and the dimensions of the Rutland 913.
Why is The Rutland so unique
It's new aerodynamic proportions are designed to deliver maximum efficiency from its 1.8m diameter 2-bladed turbine. We've given the FM1803 a new aerodynamic styling and the latest generator technology to deliver nearly 40% more power without increasing the turbine size. In fact we've reduced the weight but the FM1803 is still as robust and "heavy duty" as its predecessor. 
Suitable applications include off-grid homes, telemetry stations, telecom sites, radio/tv transmitter stations, rural clinics for refrigeration and lighting, meteorological stations, security systems, navigation aids, portable power for expeditions and military field applications, etc. 
Whatever the application you'll find using the FM1803 is convenient, reliable and cost effective. It can be used alone or in conjunction with solar panels and/or a diesel generating set to create your own stand-alone power system free of costly grid installation and on-going costs.
Includes automatic operation controller incorporating battery overcharge protection, manual stall switch to idle operation for battery maintenance, charge ammeter and battery voltage indicator 
AC voltage transmitted to controller to allow optimum windcharger siting whilst minimising voltage losses 
Latest 3-phase alternator design 
Composite aerofoil blades of durable glass fibre 
Automatic furling system activates in excessive winds to mechanically protect turbine and reduce stresses 
Controller available in 12v or 24v, windcharger unit is identical for both 
Designed to mount on 81mm internal diameter tube 
Other System Components:
Batteries - A battery bank of deep cycle lead acid cells of the non-sealed type only are recommended with a minimum capacity of 300AH @ 12V or 200AH @ 24V

Cable - Three core cable is required between the wind generator and controller, the thickness of this cable depends on the length and more details are given in the Installation Manual. Distances up to 50m should use 1.5mm≤ cable. 
Mounting Pole / Tower - a minimum height of 6m of 81mm inside diameter tube supported by a minimum of 4 guy wires is necessary. Further details are given in the Installation Manual.

Wind turbine performance specifications are not created equal......
That's because to date there are no firm international standards for how small wind turbines are "rated." Most grid connect wind turbines are given a power specification at 10m/s (meters per second), the equivalent of 22mph or 19Knots. They do of course produce more power in stronger wind speeds. Bull chooses to rate our wind turbines at this same standard of 10m/s as we believe that as the industry matures a reasonable level such as this one will be established. Manufacturers rating points vary and consequently it is necessary to compare output graphs across a wide band of windspeeds rather than accept individual rating figures for wind turbines.
So how much power will a windcharger deliver?
The real measure of performance of wind turbines is "accumulated ampere hours" into a battery over a given period of time although this is a difficult measure for manufacturers to express since the users site for the windcharger will affect overall performance. Output graphs are usually an indication of instantaneous peak power at given wind speeds but in real conditions the wind is rarely constant, usually gusting up to 3 or 4 times the average.
Wind turbines can theoretically deliver 4 times the power in twice a given wind speed so calculating total power generated using average wind speeds is misleading.
As an example we will take 10 Knots as the average wind speed using a Rutland 913 Windcharger:
the Rutland 913 delivers 1.5A @ 10knots, then we could estimate a daily yield of 24hrs x 1.5A = 36Ampere hours. However at the extreme the wind may blow at 20 Knots for 12 hours and be calm for 12hours, showing 10Knots as the average so the potential power generated can be quite different, ie at 20 knots the Rutland 913 delivers 7A, therefore 12hrs x 7A = 84 Ampere hours.
The actual accumulated ampere hours in reality is somewhere in the middle demonstrating that average figures can be misleading. This also reinforces the benefit of wind generators that run freely in low winds maximising the available power of the more regular gentle breezes as well as the peaky gusts.
Consider the "fill factor"
The wind never blows constantly from one direction or at a steady wind speed, it blows in gusts. Most micro wind turbines are fitted with a free yawing mechanism and tail fin to direct the turbine into the wind. Where they differ is in the type of generator and aerofoil blades used which greatly affect their ability to adapt to the changing wind conditions. An unrivalled feature of all the Rutland designs is low wind speed performance. Our high inertia generators maintain momentum and speed between gusts of wind, continuing to generate power where more conventional designs slow down losing power and requiring a strong gust of wind to restart them. This means that overall a Rutland will generate more power into a battery bank in a day when compared to an equally sized or rated turbine and even in cases of generators of a higher "rated" capacity and turbine diameter! See the independent tests on our news pages and compare the turbine diameters to see that you don't always need a larger unit to generate the same or more power.

To sum it up:

Low wind speed start up of just 5 knots 
Generates 90w @ 19 knots, 24w @ 10 knots
