  • Highly efficient PMG and power matched inverter, tested by TUV.
  • Highly efficient, lightweight GRP blades, tested by Strathclyde University.
  • Control system – Intelligent controller gives system awareness of wind speed, wind direction in relation to turbine axis, rotor rpm, grid availability and power exporting. Factory built and subjected to a 100 point test and quality check.
  • Safety – because the system knows about its environment and turbine speed, it can shut down in high winds and restart itself once the strong winds have decayed.
  • Safety – The system shuts down in a controlled manner in the event of a power cut or if commanded to by pressing the stop button.
  • Safety – the system employs a brake load to keep the turbine running at its design rpm for maximum power even when gusts pass through.
  • Control enclosure located at base of tower. Minimal disruption and space required at point of connection to electricity supply.
  • Integrated Inverter unit – converts power from generator into mains frequency and voltage. This unit monitors the electricity supply and disconnects the turbine from the grid in the event of a power cut.
  • Active Yaw system – an electric gear motor system turns the blades into or away from the wind
  • Fixed shaft permanent magnet generator – the windings are stationary. The magnets spin around the windings and is unlikely to fail.
  • Hydraulically actuated self-supporting tower. Can be located on “dead land”. Simplifies maintenance – can be carried out by one person, involving less effort and time.
  • Simple to install. Turbine nacelle fully assembled in factory requiring minimal on site work. Simple electrical terminations.
  • High efficiency means that the LES6000 can generate as many units of electricity as some of our competitors’ larger products.
  • The blades start turning at 2.5m/s (5.5mph) and start producing usable electricity at 4m/s (9mph). They keep producing electricity up to 18m/s (40mph). This is a wider operating spectrum than most other competing equipment.
  • Maximum power output of 6.0kW reached in 10 m/s (22mph) wind. This is lower than most other manufacturers’ equipment, which means the LES6000 reaches maximum power more often.
  • A complete kit of parts is supplied on 3 pallets + tower. All that required to be supplied is concrete for the foundation and SWA cable to connect the control panel to the electricity supply.
