PERFORMANCE

What is a unit of electricity? A unit of electricity the equivalent of consuming 1 kilowatt of power for 1 hour. 1 unit is the same as 1kilowatt hour (kWh). Power is an instantaneous measurement, whereas energy is a measure of power over a period of time.
What happens in the event of a power cut? The LES6000 is a grid tied system which means that it needs the grid supply to be present to operate. So that engineers working to repair the electrical fault are not put at risk, the inverter disconnects from the grid and the turbine will shut down in a controlled manner. This means that you are not self sufficient in the event of a power cut.
What is the maximum power output of the LES6000? The LES6000 will output a maximum of 6.0kW and is delivered on a single phase.
What are the operating wind speeds of the LES6000? The LES6000’s blades will begin to turn when the wind blows at 2.5m/s (5.5mph) and start producing usable electricity at 4m/s (9mph). They keep producing electricity in sustained winds up to 17m/s (38mph) but can handle transient gusts up to 25m/s (56mph)
What can I do with the extra electricity that my turbine produces that I don’t use? It is recommended that you enter into a contract with your electricity supplier so that you get paid for the energy that you export onto the grid. The market for microgeneration produced energy is becoming increasingly competitive and it’s recommended that you shop around for the best deal.
How do I know how much energy my turbine has produced? In the top left hand corner of the control panel, there is an energy meter which measures the number of units produced over the turbine’s life.
How do I know that my turbine is producing power? The controller in the centre of the control panel has an LCD display, which provides real-time information on the system’s status.
How can you predict what the energy generated at my site will be? An online national database exists which provides an indication of the average wind speed for the kilometre square grid in which your property lies, on the Ordnance Survey’s Landranger map range. This average wind speed can then be used to create a statistical profile of the wind resource in that square. The power characteristics of the LES6000 can then be superimposed on that wind profile to arrive at a prediction for the energy that will be generated. Of course, the actual value generated may be higher or lower than the prediction indicates.
How do I know if my site is suitable? The first step is to determine the average wind speed for your site. If this is high enough to generate a reasonable amount of energy, then a site visit by an approved installer is recommended to determine that the site is free from wind obstructions and to identify potential planning issues.
What happens if I generate more energy than I use? If the load at your site is less than the energy being produced by the wind turbine, then the additional energy is automatically exported on the Grid.
