Tri-namic Blade Profile
This is Marlec's unique blade design that brings together three key performance features in a single blade profile. What makes it Tri-namic?
Powerful Turbine Generator
The vast experience at Marlec shines through in thier new rare-earth magnet generator. Rare-earth magnets are the strongest type of permanent magnets manufactured. They produce significantly stronger magnetic fields than other types and require careful handling but payback swiftly in the power they are able to induce.
Low friction is critical to low wind speed performance and Marlec have taken these super strength magnets into their new design of brushless generator yet maintained low wind speed start-up. The Rutland 1200’s supporting structure, called the nacelle, is constructed of high-quality marine-grade materials such as a stainless steel shaft. The sleek outer casing is made from lightweight but robust mouldings to a high UV resistance specification which contrasts the distinctive blue anodised generator casing.
State-of-the-Art Controller Included
Input capacity of the unit is high, accepting both the Rutland 1200 with up to 20A of solar panels, that’s 250W @ 12V and 500W @ 24V. Outputs to 2 battery banks make this an ideal solution for keeping batteries charged on sailing yachts.
Speed governing of the turbine occurs electronically from the controller, this becomes active at 15m/s or 29Kn or 35mph. This intermittently alters the speed of the turbine to reduce aerodynamic and electrical stresses on the system.
A remote digital display is available now. The controller has built-in LED indicators and shutdown switches for the charge inputs.
Materials
Marlec construct their Rutland wind turbines using a range of modern and traditional high-quality materials which are designed to endure in a marine environment. They have innovated in their field by introducing lightweight 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 their UK factory.
Marlec Guarantee
Rutland Windchargers are designed, developed and manufactured in the UK by Marlec. They warrant their products for 2 years from the date of purchase. With over 35 years of experience in their field, they continuously develop designs and materials to ensure our products withstand the rigours of the testing environments that customers put their Windchargers through. You can buy with confidence that Marlec's products will endure, will meet their claimed specifications and that you are buying a product that has sold, in its versions, worldwide in excess of 100,000 units fully supported by their sales and engineering teams in Corby, UK.
Marlec publish their curves based on measured data and use ongoing actual performance data collected and monitored over long periods of time of the turbines running in clear and 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. The curves represent a truer reflection of the power output you can expect from your Rutland Windcharger compared with many other turbines.
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 wind speed 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. Marlec often recommend the combination of wind and solar charging to smooth out the daily energy yield.
The Marlec design team have lead the way in controller technology for micro wind turbines since introducing electronic stall in the 1990’s in preference to energy dissipation. The new Rutland 1200 controller takes another leap ahead introducing Maximum Power Point Tracking technology to optimise power generation from the turbine and solar panels.
View actual performance, the operating condition and remotely shutdown using the new Remote Digital Display -1200.The Remote Digital Display is designed to be conveniently located on board, for example on a chart table. There are a number of optional screens for continuous display: wind power generation, solar generation or the default screen where both these, battery voltages and charge status are displayed.
