Rutland 1200 Terrain Turbine Features
The Rutland 1200 Terrain combines a highly efficient wind turbine with innovative design features and a technologically advanced controller. Together they generate real-life levels of power that lead the market of micro wind turbines.
There are three technical advantages the Rutland 1200 Windcharger has over similar models in the market:
Unique Tri-Namic Aerofoil Blades
The refined aerofoil blade profile is purpose designed for quietness, low windspeed start up and high wind peak aerodynamic performance. Each injection moulded blade is identical and perfectly balanced for smooth operation.
• A rotor that remains virtually silent across all windspeeds.
• A very low cut-in windspeed that starts charging at <3m/s (6mph/9kmph)
• Unrivalled power generation of 250W at 10m/s (23mph/37kmph) and peak power of 483W @ 15m/s.
Our efficient, finely profiled Tri-namic blades ensure that the Rutland 1200 converts the maximum energy available in the wind to charge your batteries.
The Rutland 1200T generator is based on Marlec’s pioneering disk type design. Its low resistance AC operation combines the latest powerful rare earth type magnets with a 3-phase winding and low friction bearings. This is housed in a protective aluminium casing and all manufactured by Marlec in the UK.
• Cool operation which increases efficiency and reliability.
• The low resistance generator works in harmony with the aerofoil blades and controller to ensure that across the whole range of windspeeds the Rutland 1200T generates the maximum energy possible from the available wind.
• The generator is sealed to withstand weather conditions around the world.
The overall benefit is greater Ampere hours of energy delivered to your battery
Elegant and Aerodynamically Styled
The sculpted nose and nacelle efficiently direct the flow of air leading to the built-in tail fin which directs the rotor to the prevailing wind.
NEW MPPT Terrain Controller Features
This purpose designed Rutland 1200 Terrain charge controller incorporates hi-tech and other optional features to fully optimise power generation from the turbine system and prevent overcharging.
The controller is a key component in the Rutland 1200T’s holistic design providing intelligence at managing the energy, the turbine and the battery to achieve maximum Ampere hours of charge to the battery bank per day.
By design the controller will operate with lead acid, AGM, and gel batteries. The charge parameters can be programmed using the Rutland Controller Interface Cable and PC App for other battery technologies.
Maximum Power Point Tracking
MPPT technology is an intelligent microprocessor controlled feature that electronically optimises power generation. This enables the Rutland 1200T system to commence charging at very low rotor speeds, maximising typical daily low to medium windspeeds.
Digital technology used by our engineers very effectively prevents batteries overcharging. Battery voltage levels are continuously monitored and as full
capacity is reached the turbine speed is controlled thereby preventing overcharging. The blades may run slowly and automatically resume normal operation as the battery
Multi-Stage Charging Regime
An algorithm embedded within the overcharge control provides multi-stage charging to maintain it through Bulk, Absorption and Float phases. The system responds to changes in the state of the battery to deliver as much available energy to maintain or reach full charge capacity. This charging regime promotes good capacity and battery longevity.
A temperature sensor is included and when fitted this feature automatically adjusts the charging regime voltage levels according to any variation from the standard 25˚C settings. This ensures batteries reach and maintain full capacity whatever the ambient temperature.
Remote Voltage Sensor
This sensor wire facility detects battery voltage levels for the controller operation when batteries are positioned >1.5m away. This overcomes voltage drop that may occur in long cables preventing full charging performance. 2 positions are available in the event that 2 separate battery banks are connected via a separate charge splitter.
Serial Data Socket
Provides a connection for user options;
Optional Remote Display, data collection for professional systems or Marlec Controller Interface Cable with App for programming of Voltage parameters and auto shut-down required for other battery types, e.g. Lithium.
Run / Stall Button with LED Indicator
Used to manually start and soft stall operation. Soft-stall is a deceleration of the rotor until it eventually spins at a slow idle. Bi-colour LED indicates charging status; Standby, Charging and Regulating.
Battery LED Indicator
Tri-colour indicates battery charge level.
Electronic Over Current Shut-down
This protection automatically activates in high currents to reduce electrical load on the generator and mechanical load on the tower. This stalls the turbine and resets after 5 minutes, it may cycle in high winds.
Electronic Over Temperature Shut-down
Automatically activates if the controller internal operating temperatures are exceeded. The turbine is temporarily stalled.
Rutland 1200 Remote Display
View actual performance, the operating condition and remotely shutdown using the new Remote Digital Display -1200.

Performance of the Rutland 1200 Terrain
Actual Performance Data
We publish our curves based on measured data and use ongoing actual performance data collected and monitored over long periods of time of the turbines running in real wind conditions.
This means the turbines are also subject to side winds, upwinds and sudden changes of wind direction (these are the causes of turbulence) experienced at a user’s typical installation.
Our curves represent a truer reflection of the power output you can expect from your Rutland Windcharger compared with many other turbines.
Whats a Power Curve?
A power curve is usually given by manufacturers to represent the performance of a wind turbine. Some may be based on theoretical or predicted output and others plot the power achieved under steady state conditions.
Wind tunnel testing and turbines run on vehicle rooftops can provide useful information for a manufacturer but power curves derived in this way need to be understood as running in a clear and unobstructed wind flow so they do not represent what is actually achieved in real wind conditions. Power curves from theoretical analysis cannot be regarded as representing what is actually achieved at all.
A more useful guide of how much power you can expect from your turbine is the Annual Energy Yield. That’s because wind energy is a “cube law,” which means that when the windspeed doubles the power potential is 8 times!
Check the Annual Energy Yield bar chart which uses the Rayleigh distribution to calculate the Ampere hours of battery charging you can expect at given average wind speeds per annum.
As these are averaged across the year you should consider how these figures will ebb and flow across the seasons when you might expect a higher average during the windier seasons. We often recommend the combination of wind and solar charging to smooth out the daily energy yield.
