This continuously matches the turbine speed and generator to their optimum performance to deliver more ampere-hours into your battery ……and a by-product of this optimised efficiency is a virtually silent wind turbine!

Rating:   Good price quick delivery. 19 July 2016  |  Frank Very quick handeling and delivery to the Netherlands ,in two days. The Rutland works great and very very silent compare to my Air X who give up already after one year, paint come off water inside bearings and electronics all become black and need replace.

Product Information

Rutland 914i Wind Generator Features

• Delivers more ampere hours per day.
• Produces up to 30% more energy than Marlec’s highly successful and market leading 913 model.
• Uses the very latest technology and features Marlec’s innovative new MPPT system.
• Same compact size yet almost 3 times more powerful. The first 910mm diameter Rutland turbine produced 50W @ 10m/s (19 knots) and on the 914i it now produces a power rating of 140W @ 11m/s.
• Aerodynamic style.
• Extremely quiet and smooth in operation.
• Rutlands have over 30 years of worldwide sailing experience and have been used on sailing yachts because they give their owners total peace of mind and complete confidence.

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 their products withstand the rigours of the testing environments that their 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.

Rutland 914i Performance Data

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. Their 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.
