• Originally designed for industrial applications, durability and reliability is the corner stone of the LE-300 architecture
• 5 year warranty backed up with excellent customer service from Leading Edge Turbines in the UK

This bundle of equipment includes all of the basic equipment (turbine, run/stop switch and diversions charge controller) that you will need to get a LE-300 wind turbine up and running on a basic battery charging system.

The LE-300 is a quiet, powerful yet lightweight 300 watt wind generator for any application. Fully optimised for marine conditions, the LE-300 wind turbine is also used extensively in a variety of industrial applications, such as powering communication and remote monitoring stations, and in very extreme environments such as Antarctica. Manufactured in the UK, the LE-300 has a proven track record in applications as diverse as powering an Antarctic research station, charging batteries on boats and industrial applications such as road signage. Its excellent power production stems from an exceptionally low start-up wind speed and superb high wind speed output. Designed to withstand the most extreme wind conditions and environments, the LE-300 is also extremely easy to integrate with solar panels for hybrid systems and can be left running through the strongest winds.

Available in 12V (Order Code: N24QU) 24V (Order Code N25QU) for battery charging applications, the LE-300 wind turbine can also be grid connected.

Efficient design from years of experience in the field:
The LE-300 is designed around a unique low inertia axial flux generator which utilises Neodymium rare earth magnetic materials. This alternator has zero ‘cogging’, which, together with its highly efficient and low ‘TSR’ Whispower ™Blades, allow the turbine to spin in the lightest of breezes and to react quickly to gusts.

Small and lightweight:
The LE-300 turbine has a uniquely designed aluminium alloy chassis that not only gives an overall turbine weight of just 6kg, but ensures responsive reaction to gusty winds. This reduces the overall size and weight of the turbine and keeps the space envelope small enabling the turbine to installed on yachts with ease. The turbine is fitted with integrated yaw slip-rings that allow the turbine to swivel 360 degrees continuously in order to follow the changing direction of the wind.

Rugged and reliable:
As the LE-300 has been designed for industrial applications in harsh environments, it has a heritage that is based around reliability and durability. The turbine is designed and manufactured to be as rugged as possible giving a predicted design life of 20 years with little maintenance required during that period. The LE-300 survives destructive high winds by means of a simple passive aerodynamic design that limits turbine RPM and power output at a certain threshold. The LE-300 is manufactured from high quality aluminium alloys and stainless steel which has been laser processed, CNC machined, hard anodized and powder coated to ensure that the turbine will withstand the harsh effects of the extreme environments. The various fixings are manufactured from A4 stainless steel that can survive the harshest of environments. The bearings are sealed for life and fully lubricated, so no greasing or maintenance is required.

Pack contents:
• LE-300 wind turbine
• Run / Stop switch - used to allow the turbine to be safely braked and electrically isolated from the circuit

Rated 4 out of 5 by from Nicely made but fiddly to assemble I rely on three LE-300 turbines to charge my batteries when my solar panels struggle, particularly in the dark Winter months, and they certainly do make a useful contribution. I live 'off grid' and although my wife and I do have a diesel generator, in practice, during 2015, we have only fired it up on two occasions after a prolonged period of no sunshine or wind. My neighbour has a competitors turbine, so I will write this review as a comparison to the Rutland 913 which is a very similar machine. The 913 is easier and quicker to put together, with the LE-300 needing a lot of patience to get the blade tips evenly spaced, a difficulty that does not arise with the 913. Once assembled however, the LE-300 seems more sturdily built and yet much lighter in weight, making it easier to mount on a tall mast or scaffold pole. In my experience, the outputs of both machines are far lower in real life conditions than the manufacturer's information would suggest, with the LE-300 being better than the 913 over all. The published output curves assume a clean air flow with no turbulence, short cable runs or hugely thick cables and most importantly of all, a flat battery. My LE-300s are 20 feet above the ground and 1/4 mile from trees or buildings so the airflow is pretty clean and yet the best output I have ever recorded during 50 knot winds was 9 amps at 13v, so 108 watts for each turbine. During more average windy periods I can only rely on 1-2 amps, with an average daily output for each machine of perhaps 15-20 amp hours per 24 hour period, which is much lower than I had hoped, but still better than a Rutland 913 that is just yards away. You can buy a stop/run switch for the LE-300, but the manufacturer recommends that the turbine is never left switched off during very windy conditions without the blades being physically restrained with string, otherwise overheating will occur. If one needs to tie the blades anyway, then the optional switch is a waste of time; just use string. The LE-300 is slightly noisier than the 913 and it also transmits marginally more vibration down the mast. This may be an issue if you sleep in a cabin under a pole mounted turbine in a boat for instance. During windy conditions either turbine may need to be tied up in order to get a good night's sleep. Overall, solar panels are cheaper to buy, easier to mount and output what the manufacturer says they will.... in the Summer at least.

Can I use this with a 150w solar panel kit ?

Asked by: Nick
You can't combine them together unless you have a dual charge regulator that can handle both wind and solar inputs. However you can use this in conjunction with an existing solar set up as long as you use the charge regulators provided by both kits. Both regulators can be attached to the same bank of batteries.

will this power small room ie lights tv fridge

Asked by: pete
Not on its own its part of a system that you would need to build, It would need to be connected to battery's and a inverter. Will it power items is not a questing we can give an answers to with out knowing how many watts you want to use and for how long.

can the turbine be easily adapted to generate 3-phase in case the battery is at the end of a long cable run? A 12v bridge rectifier would then be fitted closer to the fuseboard.

can it supply the whole house electricity?

Asked by: apolosi
The answer is yes, if you are excited by adapting your lifestyles to what the weather is doing outside. The answer depends on the amount of battery capacity somewhat. Your house can be wired up to run 12v led lights, you can run laptops, car stereo, speakers, satellite tv all without inverters if you buy 12v appliances. You will just need a generator to run a washing machine (disconnect the thermostat and add hot water manually on the first cycle). Make sure your 12v circuitry is properly fused and that your have a dumpload to dump the excess electricity into heat when you battery/batteries are charged!
