Here is a pic of a whisper 200 that was recently set up. This is on a 50 foot tower. Nice setup, with 3 sets of guys, with Gin pole. Was apparently a big job. Imported tower Kits need work, to fit pole materials available here. This is a grid connected unit, with PVE1200, and matched controller. No power production details yet.

So much for their easy to set up towers even at $1400 +pipe Certainly an elegant generator and pole mount but I was always put off by the blade extensions and output 1000W at 11.6m/s as opposed to the competition who rate their turbines at 9-10m/s. in which case its more like 900W at (36km/hr)10m/s AT more than twice the height of my tower but I'd hope it would make up for the extra wind required. I'm thinking should be a really nice piece of kit at $4700+ and at 2.7m diameter, obviously catches 5.7m2 which is a full 1.3m2 less than a 3m rotor. 20%less. They do quote 1896kw/hrs a year for an average windspeed of 5.4m/s which is 120KW/hrs lower than a SOMA rated at 10m/s but has the same diameter. So $4700+ PVE1200 $2000+ tower and anchors $2000+ +cable $500 + installation $2000. Id make it at about $11,200.+ depending on how the bits were sourced and install actual costs. I think your setup is in another league Gordon. Hell I think your F&P would give it a run for its money. They claim output doesnt drop with furling but the graph clearly shows it does Its great that its up and any mill is better than no mill, but to me its just inspirational. A Phillm machine at 1/4 the cost even with the iron core drawbacks of the F&P is starting to look FANTASTIC! In conclusion - The OZ-AX-FX and the soon to be AXFX400 should be able to easily match the price and will kill it two times over for output. I'm hoping My dual will see it off too even with the lousy 7m hub height (20% more swept area) and wind increasing with height call it 10% more wind thus 25% more grunt available. as you suggest time will tell. I have a deal with dad, if it breaks 1500KW/hr in a year, we're going for an AXFX as the cost can be justified. After all no better proof than in the pudding. BTW of the logged data you have how much does the F&P do/annually and how much does the Axial flux do? Luck favours the well prepared |

Gordon Thanks for the post of the new Whisper. Nice to see an American made mill down under. KarlJ There is somethng to be said for going with an a factory made and factory back machine. I would think most folks (unlike us) would prefer to buy new and start cranking out watts asap. On the flip side when I tell people that I built mine I get some big smiles and lots of questions. Most folks around here know nothing about wind mills so after I tell them what little I know makes me look good and it's lots of fun.  Jim |

they only have a 12 months warranty Jimbo, but I appreciate the appeal of a commercially made machine. My "commercially made" machine is Phillm dual, he doesnt have a big factory nor a store yet, but time may change that!!! I see there is a ripper PMA on ebay with neos the works, perhaps could solve your problem for MORE power. at this price I dont think you'd buy the neos... Big Gen Luck favours the well prepared |

KarlJ Dam thats a nice PMA (ebay) I asked for more info on this unit. Thanks Dude. Jim |

INDEED, hope you can score it for peanuts, cheaper than buying neos. Looks similar to the skystream... Luck favours the well prepared |

430rpm cutin for your 48v system???? You will need a very good boost system to do any good in normal winds I think. Even a little 8 footer tsr 7 will need a 18mph wind to get to cutin. How often will that be? Rather buy 225 USD of neos. ..........oztules Edit: Mine blew up my good 50w 12v halogen spot light with 1/2 a turn only by hand..... and I mean only half of a rotation from stop...... teach me for showing off I guess  Village idiot...or... just another hack out of his depth |

Oztules You have some information on this PMA? I wonder what the manufactuer built this alternator for, automobile, trucks, gas generator etc? 430 rpm cut in is high for sure. Jim |

No Jimbo, only the blurb as quoted on the site: [quote]It will brightly light up a automotive tester bulb by turning it very slowly by hand! Works in either direction. It reaches 12 volt at about 100 RPM! It has a Electrical Brake! and a mechanical one (I have removed it but I can send you it, if interested) It weights a whopping 28 lbs! (See photo, taken with a 10 dollar bill, to get an idea of how big it really is.)[/quote] Now it lights a little 12v test globe turned very slowly.... but needs 100 rpm to make 12v???? so for 12v cutin (really 13-14v) we need 110 rpm... guess how much for 48v( more like 52v).... near 430-440 rpm depending on state of charge of the batts. Either thats a big $10 bill, or a small alternator. 28 lbs is very small to support large blades. Because of it's very late cut in, it should be good for 700 or more watts I would guess.... but it is the cut in that will disappoint the most. More suited to a little 24v system I would think. ..........oztules Village idiot...or... just another hack out of his depth |

OZ Thanks for your help with this. I am happy with my mill it performs better than I could have hoped but you know how it is MOREPOWER feels better. Jim |
