Just tell me where the hell you come up with 9kw, and how? Best you do some research before you answer that, because it shows you dont read what has been posted, or even remotely understand about harvesting energy from the wind, and what can be expected in power production, other then your understanding of what some glossy brochure said in some sales pitch you have misunderstood. Until you can understand the basics of how a wind turbine works then there is not a lot of use trying to give you information to work with. Sometimes it just works |

if I plug figure inot How Much Power Can I Generate With A Whispering-Winds Generator? Below is a unique free online tool from Whispering-Winds to estimate the amount of electricity that you can expect to be produced by any of Whispering-Winds Generators at your location. Please enter the "Rotor Diameter" and your average annual "Wind Speed" (at the generator height) to see how many kilowatt hours you can expect to generate per year. rEUK.co.uk - Wind Turbine Output Calculator Rotor Diameter: metres (0 to 150m). Mean Wind Speed: metres per second (0 to 12m/s). Cut-in Speed: metres per second (0 to 7m/s). Cut-out Speed: metres per second (10 to 25m/s). Turbine Efficiency: percent (10 to 59%). Weibull Shape Parameter: (1-3, so use 2 if unsure) Predicted Turbine Output 201 k i used rotor daim 2.6 metres blades 1.3 metres and cut out spped 25 metre/ sec - I have never seen this in brochures only survial wind speed |

opps I forgot to put my mean wind spped as 4.23 m/sec Rotor Diameter: metres (0 to 150m). Mean Wind Speed: metres per second (0 to 12m/s). Cut-in Speed: metres per second (0 to 7m/s). Cut-out Speed: metres per second (10 to 25m/s). Turbine Efficiency: percent (10 to 59%). Weibull Shape Parameter: (1-3, so use 2 if unsure) Predicted Turbine Output 1,473 kWh |

turbine is rated at 2kw but has max power at 3 kw so 3 turbines at max power 3 kw x 3 =9 in my area i get some pretty big winds |

so 3 turbines at max power 3 kw x 3 =9 in my area i get some pretty big winds Seen you like the details on OEM website to quote all your information from, then you would have surely noticed their listed 2kw mill has a blade diameter of 5.5m and their 1kw mill has a blade diameter of 4.0m. The listed 500 watt mill has a blade diameter of 2.6m Now you have a blade diameter of 2.6m for your mills, dont that tell you something about the mills you have. Sometimes it just works |

Due to the fact we really dont know what mills you actually have, it is not very practical to make recommendations to equipment needs or design advice. Can you take some clear photos of the mills and equipment you have and post them to the forum, as this might give a better indication to understand the actual products you have. Sometimes it just works |

plan collect towers from steal fabricator dig holes cement in bottomn of tower secure cable need specifications someu tube videos use welding wire and thread thru the 3 metre sections try and screw tail fan together and attach rotor head and blades I am so far i I canot back out work on problem 1. cannot connect oem to grid 2 cannot use sma inverter need batteries 48 volt 300 amp |

my units look the same as on cindys site the rotor is a bluey colur will try and get picture of rotor |

| Downwind Guru Joined: 09/09/2009 Location: AustraliaPosts: 2333 |
Also measure how wide the rotor is front to back, and the diameter of the rotor (the round part) Even the axle size might give some indication too. We never said to back out, its just a matter of first knowing what you have to work from there. Sometimes it just works |

axle is is that the bit that attaches to the pipe tower I just left a message at steel fabricators I bought $2600 of black pipe quality bluescope econ pipe cheaper but I do not want to take any risk if the the tower falls over due to inferior pipe and starts a fire or kills someone bought enough to make 4 towers 3 sections total 9m 13 inch botomn 250mm middles 100 mm top problem I have been trying to get a meter on thru agl and sp aus got the last of about 5 service orders into sp aus on 19 ths sp aus net have 10 ten days to install meter if I do not get meter in I will lose my solar credits - lose have as the multiply goes from 2 to 1 and one condition is to have your meter on by december 31 if I do not get my meter I can claim agst sp aus net the went to my paddock and got lost a couple of time due incompetence part of the problem was I bought my horse a prime agricultural land paddock and the council were not supposed to have subdivided it off so they never gave me a property identifier numbber and sp aus net go by council property identifiers sp aus net had previously installed a pit for me sp aus net would not give me another pit near my drive I had to lay 260 metres of cable to my drive or pay 15 k for a cross arm on the pole I got my contract in to agl for the luxury 0.33 cents the day before the tariff drops to bugger all .08 cnets i put 8 x 300 simax panels on my horse shelter shed 5 north and 5 on the back west all I could fit on |

If the mill is not attached to the nacell the axle is the black shaft, i think its the same size right through to the front where the tail fits too.

think its a bit different there is a piece of pipe coming from the rotor where u attach to the tower with a few bolts as inn u tube video |

going to site tomorrow try and get picture |

Do you start to see the bigger picture, if there is a small change in turbine design, then it may not be what you think you have as a mill. Or which version or which model or what ever. Do all the mills have the same 2Kw marked om them, and are they 100% the same in every way as far as you can tell by inspecting at them. From the cost you have outlaid to date and looking at the return factor i struggle to see this installation ever break even, with solar and wind combined. As you say no turning back now, and you are only able to make the best of a bad situation. Sometimes it just works |

I will bet you a half eaten christmas pudding its a 500 watt mill, if that is the case. (one of the versions that may produce 2kw in a cyclone if it didnt self destruct before hand) First indication, do it have the cooling fins on the rotor casting? (like in the photo i posted) If it do, then the measurements of the rotor, including axle dia. Just to warn you, it might be a case of you think you have a total of 6-9Kw mills and only have a total of 1.5 Kw mills. Until we know, its just pissing away your cash, for example if you build a tower for 2-3kw mill and only fly a 500w mill then its a huge overkill in cost, same for inverter and batteries, wiring, controllers, etc. Workout what hardware you have and the rest will fall into place. Sometimes it just works |

Im thinking it will be the later version with the bigger generator motor than the 500W but exactly the same type of down wind design as the very first , with welded blade mount spigots , the black bike wheel end plates as in the pic will give it away and the stupid looking tail out the back. Heres a pic of the parent 1000w wheel motor that they turned into a 2000W generator. 
Hopefully you can work out how to upload photos to help this along. PhillM ...Oz Wind Engineering..Wind Turbine Kits 500W - 5000W ~ F&P Dual Kits ~ GOE222Blades- Voltage Control Parts ------- Tower kits |
