tomqu7 Are you deaf? STOP shouting at us use lower case text please. I hope you dont intend to feed 3 or 4 windmills direct to 1 inverter, it wont work! As for turbine voltage, there is no fixed voltage and the voltage will vary up or down depending on the speed the turbine spins at, and each turbine will spin at different speeds depending on the wind passing them. It seems you woke up with a bright idea one day, and did not do your reasearch before starting this. Where did you get the turbines from? From what information you have given i would think you have been mislead in the turbine capacity, and your mills are no more than 1Kw or even perhaps only 500 watt mills 
This is not something that OEM done wrong, but what has been happening with a seller upgrading the capacity ratings of the mills to suck in people like yourself. If you look at your packing boxes you might well see where to original packing stickers have been removed and taped over. All OEM mills have a sticker on the packing box stating the rated capacity of that mill. Pete. Sometimes it just works |

on the rotor on the side is stamped in metal 2 kw the instructions are in german and english there are no specifics I nweed some to get a grid tie inverter plan if u google oem windpower u find a guy in the snow on u tube in usa they are supplied with an inverter in the box he has specifics of the inverter on his site perhaps I could convert to australian re phil m said the turbine could spin out and burn out in the box i got a resistor i bought 3 one of them had a kill switch not much use as I am 90 km from paddock would have to dash if storm forecast and turnoff kill switch ? |

I went on to whispering winds china who make the turbines they have a 2 kw on their website but max 2.2 kw i contacted cindy who said I had an old model and they do not have any specifications On their website they say they have australian engineers and show them visiting their factory how to find the australian or their american engineers I have to buy a sma grid connect inverter and not sure sma wants to know voltage of turbine ???? would this work so I have 3 x 2 kw turbine max 3 kw - this is in instructions so i buy a 12 kv sma grid tie inverter get it wired up and adjust /programme inverter when mill running if I can find some with the skill to programme inverter on the spot need to find those visiting engineers I asked cindy did they have an australian contact and she said they didn't |

First a little history lesson. Both Phill and myself have worked for OEM in the past as consultants or as you put it engineers, we are no longer on their payroll so are not passed on as contacts by Cindy. OEM have produced many different versions of rated turbines over the years, each model is superseded by the next version. A lot of older stock was sold to a supplier here in Australia, who took it upon themselves to relabel the turbines to twice the rated capacity for marketing reasons, this has nothing to do with OEM. From what i can workout that you may have is a 1kw mill, which was originally badged as 2kw, after much testing OEM derated that design to 1kw, yes it can produce 2kw but only in a cyclone, hence why it was derated to 1 kw. OEM has always tried to do direct grid tie connections with their mills to varying degrees of success, my advice to them was the mills are not suitable for direct grid tied connections, the inverter in the video you refereed to is a Chinese made inverter that DO NOT comply with regulations for 90% of countries, this one included. As far as i am aware Australian regulations will not except a OEM mill direct grid tied connected, the mill has simply never be tested to comply with our regulations, although people have done it, but it is not approved or actually legal. The work around the problem is to put the mill power into a battery bank and use a approved GTI from the battery to feed to the grid, this system is legal in most states including Victoria. The problem with using a windy boy is it has anti island built in, this causes a delay (by law) preventing instant connection to the grid, what happens is the mill will run away during this delay period and can burnout or self destruct. Then every time the wind drops and the mill stops producing enough power to keep it connected to the grid it will disconnect from the grid and need to go through the delay period again when the power level is high enough to allow connection. This is why almost everyone uses a battery bank to solve this problem, as the mill will ALWAYS remain connected to the battery keeping a load on the mill. I think you have a lot to learn and understand, and have some half baked idea that you can do what is just not practical without much redesign of the system and the way it operates. By all means go ahead and prove me wrong, but when you start to pick the pieces of mill up from scattered across the paddocks, just remember i warned you so. Pete. Sometimes it just works |

Governing System - This unit is an integration of automatic braking system, controller and logger. It will automatically monitor the rotor speed and keep it at or below 250 RPM. When the wind is very strong, the Dynamic Braking will be activated. The power from the generator is diverted to the Dump Load, which slows the rotor until it is slightly below 250 RPM. This allows you to get the most watts possible from the available wind. I HAVE ONE OF THESE UNITS IN BOX |

The Data Recorder is another powerful unique function that comes with Whispering-Winds governing system that allows you to record the windmills performance to a computer 24 hours a day. The data can be viewed in excel format, as well as plotted to a power curve graph in respect to wind speed. The recorder will allow for 5 parameters to be recorded: battery voltage, amps generated, windmill RPM, output wattage and wind speed (with the use of an optional anemometer not supplied). DO i GET THIS GOVERNING SYSTEM DATA LOGGER IN MY THING |

DUMP LOAD – These are heavy duty dump loads which contain wire-wound resistors (2kw - 2 ohms, 4kw - 1 ohms) which have been especially designed as dump loads for wind generator use. The one millimeter steel case is yellow powder-coated for many years of heavy use. The wiring terminals have an extra cover to protect the terminals and to assure safe operation and use. i ALSO GOT ONE OF THESE TIN BOXES IN THE BOX LABELLED RESISTOR |

To add a bit more to this tale , in which I have told you Tom via private emails and you do not seem to get the gist of what I have already said which is pretty well exactly what Pete has told you. If you keep on the path you are wanting to go on the only happy person will be the person you buy the inverters from. What I can make of the mills you have been sold is they maybe the larger downwind 2kW mills that were produced for a period and dumped here in Aus , Good luck with those when the wind starts howling and I hope you don't live in a high fire zone area.

SO THE ABOVE SYSTEMS THE RESISTOR AND GOVERNING BIT DO NOT DO IT AND i NEED A BATTERY BANK TO CAPTURE THE ELECTRICITY AND THEM FEED IT INTO THE GRID OTHER EXPENSIVE TURBINES DO NOT DO THIS IS THIS JUST BECAUSE WE HAVE ONE THAT IS NOT DESIGNED.....????? |
||||
| tomqu7 Senior Member Joined: 09/11/2012 Location: AustraliaPosts: 168 |
a approved GTI WHAT IS THIS SO IF i INSTALL 3 OR 4 SUPPOSED WIND TURBINES i WOULD NEED A THUMPING BIG BATTERY PLS ADVISE i WOULDNEED A SHED TO HOUSE IT THE MAN ON U TUBE IN THE SNOW HAS THE SAME TYPE AS ME WITH OEM WINDPOWER ON THE TAILS AND HE CONNECTS TO BATTERY i THINK THE EXPENSIVE TURBINES COSTING 6 FIGURE SUMS DO THEY GO GRID OR BATTERY SO THEY GO GRID BECAUSE OF BETTER DESIGN FEATURES SO i CONNECT TURBINES TO BATTERY WHAT DO i NEED IN BATTERYS |

Chinese made inverter that DO NOT comply with regulations for 90% of countries, this one included. THE CHINESE INVERTER ON OEM USA SITES RE THIS TYPE OF INVERTER IS THERE NONE LEGAL IN AUSTRALIA ANY WAY SMA IS THE ONLY ONE THAT HAS 12 KW INVERTERS THANKS FOR YOUR ADVICE ABOUT FUNCTION OF SMA INVERTER IN PADDOCK NO ONE THERE DO NOT WANT FIRE OR i WOULD BE HELD RESPONSIBLE |

You are shouting at us again, take caps lock off and use lower case text If you continue to use upper case text i simply will not reply!!!!! ITS RUDE!!!! It may be the same company that imported the mills, i dont know as they change the name every 6 months or so, you are not the first here that have purchased a mill and perhaps not got was advertized, and all past people have taken action against the seller and got no where, they change their name and move on. As for the controller you refere to, a part of my involvement with OEM, i designed the circuitry for their latest controller. In many ways what it was designed to do, is often different then others market it to do. Yes it will allow for data logging, electronic braking via rpm or over voltage, but was not designed to control battery charging or grid tied control. Now after your last little dummy spit, i advise you to calm down and we look to find a workable solution, simple enough for you to understand, because what you indicate from attitude im wasting my time even replying to you. Secondly you are HI JACKING another thread for your cause, so i advise you to start your own thread that we can continue a discussion with your problem. Pete. Sometimes it just works |

Tom , I think you should start a thread separate to this as what you are talking about is completly different to the 500w mill . Also you need to learn how to post , when the reply box is full you just keep typing and it will scroll down so you do not have to hit "post reply" when the box is full. This will stop all the individual replys also "CAPS LOCK ON" means you are shouting at us . Some pictures would be handy .

Ok you have taken the first bit of advice and not using uppercase text...good. Now take the second bit of advice and start your own thread under windmills and then we will discuss this further. Pete. Sometimes it just works |

Hi Tom, I dont think you will find the answers you need on this forum. You need to have a face to face conversation with someone who is an electrician with some experience in off grid installations. Trying to find the answers on a forum is like learning to drive a car by taking instructions over the phone, its just not going to happen. What you hope to achieve with your wind turbines is no easy task, and will require some expertise. Be careful about saying things like "I was defrauded by company X", as by saying such things on a public forum, you can be sued for defamation, even if your case is strong. Posting a message on a internet forum gives you no anonymity. I know its all ready been mentioned, but capital letters is regarded as shouting, and will quickly distance yourself from readers. Also all capitals is harder to read. As mentioned, this post was originally about another windmill model and not relevant to your model, so I'll close this thread now. You can start a new topic if you like. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |
