Goal 7: Affordable and clean energy.
Mass produced in the United Kingdom by Marlec, tens of thousands of the original 910 Rutland series have been sold world wide. Also licensed to manufacture in developing countries, but not specified where.
Distribution through Marlec website and many other resellers such as RS Components and Allied Electronics. It has been licensed for manufacture in developing countries.
Exact number unknown. However, Marlec has installed more than 100,000 of their Rutland Windcharger turbines.
Is it a turbine, kite, etc?
How tall is this system and/or how high above ground does it operate?
The radius of the system as it is turned by the wind
What type of controls are used, remote diagnostics, etc.
- Automatic “furling” tail fin directs the turbine out wind above 15m/s for gale protection.
- Low wind speed start up maximises power generation in low winds.
- High grade construction materials for durability in the harshest environments.
- Provides a D.C. power supply to charge 12 or 24 V battery banks.
- Designed for use on permanent land based applications where low power is needed for professional and domestic devices.
- Ideally mounted on the Rutland Land Tower and Rigging Kit – see product catalogue.
The wind turbines are constructed using robust, light-weight high density nylon and glass reinforced, UV stable materials. Other materials used are marine grade aluminium, stainless steel, and sealed for life bearings.
Users can shop for spare parts directly from the manufacturers.
Not specified. Free replacement for all defects for 24 months from manufacturer.
- Startup Windspeed: 2.6 m/s (5.8 mph)
- Produces 22W at 5 m/s wind speed
- Produces 138W at 15 m/s wind speed
- Furling tail turns turbine out of winds above 16 m/s (35 mph) to protect the system in gales
- Maximum Wind Speed 35mph
- Low wind speed start up of just 2.5 m/s
- Low friction 3 phase alternators give a smooth and silent output
Tested by RS Components – includes a Statement of conformity:
“This certificate confirms that the product detailed below complies with the specifications currently published by RS Components and has been subject to the quality conditions of our registration to the BS EN ISO9001:2008 management standard. Furthermore, where applicable, it provides assurance that all electrostatic discharge sensitive devices have been handled and packed under conditions that meet the administrative and technical requirements of the ANSI/ESD S20.20:2007 and the BS EN 61340-5-1:2007 electrostatic control standards.”
Tests done in the UK by Marlec and RS Components. Both based in Corby, Northants, UK.
Users should be aware of never allowing the turbine to rotate unless it is electrically connected to a regulator or baterias. Connecting open circuited running turbines to the electrical system can cause overvoltage and damage to the system.
It is recommended to handle the system with caution at all times to avoid electric shock.
Avoid maintenance or repairing actions when the turbine is rotating.
Users should check carefully the polarity before connecting the Windcharger.
Complimentary technical systems includes solar photovoltaics that can be mounted on the same pole.
