Secured funding for the quote Effsun sent me,Just waiting on the payment method they want.. I am so excited..Big boys play with AMPS...
Yes I own one. That's what one of my new towers is for. Just a turn with my hand can put it over 50 V. Still searching for a proper grid tie for it. Have some questions out to suppliers and still waiting for a response . Will share with you when I hear anything .
You must of not got the 56 volt version they offer here http://www.effsun.com/index.php?pag...ategory_id=16&option=com_virtuemart&Itemid=64 They do offer 2 other 100+ volt versions Mur..Must be what you got..
I have there pdf for all the Gens they offer,if you dont have it I can email it to you...Thats how I knew they offered every model with different thickness of stator wires for different voltages.
Jason, I do not have that PDF so please send It to me . All my info was from Alibaba, and Josh helping me by speaking with them. I started this project and purchase about one year ago, it has just taken a considerable amount of time for me to put it together. But getting closer ! My 2 kw is called TFY2000-56-450 the power chart will show 2500 w @ 500 rpm, Anyways after the math is done the cut in is approx. 110 rpm with a max volt of 255 @ the 2500 W Just for interest my 1 kw is called TFY1000-56-500 The power chart is showing approx 1550 W @ 500 rpm Math = Cut in is approx 125 rpm, with a max V of 225 @ the 1550 W I have done some bench testing but the information is not even worth sharing due to the low V range of the inverter. The inverter co I had contacted has returned my message wishing for a more detailed description of my turbine. This info will be good for both of us to help us make decisions for a matching inverter system,,,, or have you found one already ? I will copy the link and send it to you shortly mur
They send a Proforma Invoice. Then I had to do a TT wire transfer at the bank to their account. Shipping takes about 4 days.
This is the site I have been searching out. They were speaking with me again this am., so getting closer for more info. http://yifagroup.en.alibaba.com/pro..._wind_inverter.html?tracelog=cgsotherproduct1
See now you got me worried Mur, i am suppose to be going to the bank in a few hours to take care of the T/T and I am having doubts..What if I spend the almost 1k and have a unit that doesnt even fit into my system that I have built(VOLTAGE WISE).. Effsun hasnt wrote me back on any concerns for 2 days now..
They got back to me and the charts are based on open volts and shorted current. That is why at 493 RPM I only got 231 watts out of my 600 Watt. By the chart it should be closer to 400 watts for the 600 w at 24 volts. I have shot 20 or so emails back and forth on this. Sometimes it takes 4-8 days for any response. I was just told they are moving the whole company to a new building and will not be able to get back to me till late next week.
Tom are you using 3 runs of copper in from the turbine?.I PROMISE more out put if you run each leg of AC into a 12g cord to the rectifier.. I waited to send money until I know more about volts to rpm on the unit..It need to be able to have its own circuit to feed but also must fall into the 10-60v grid ties bank..I will deal with large amounts of amps. I also am waiting to see,it looks like a angeled rod on the rear of the units for a easily furling tail but balancing weights need to go on the back to offset the 55lb motor and 25lb baldes/hub..It will definately need some engineering.. Part of me wants to just do the 750's with WN frames but with all the concrete and work for the towers it makes sense to have the largest output possible..
I have (3) 25 ft 6 gauge wires running from the turbine to the rectifier. Also have 8 gauge running about 2 foot to the GTIs I have. The test was with a drill with the new one. PMA direct to the rectifier and 3 ft 12 ga to 24v of batteries using a watts up meter.
Well I don't want to scare you but I think you might have a concern hooking up to your 10-60 V inverters. I have not bench tested the 2 kw yet but just for interest I put the 1kw on a drill to the rectifier on to a 10.8-30 , 500 Sun. It was real difficult to try and make my drill go slow enough with out going over volt. The drill was overheating trying to go slow enough to do 12-14 V ( hardly turning at all) then as soon as the drill started to turn over I was over volt right away. I have not tried my 22-60, 1000 V Sun on it yet. What a difference in clamping that turbine from spinning it with no load by hand then spinning it by hand while it was loaded by that 10.8-30 inverter,,,,,,so difficult you really couldn't . The reason I have been checking other inverter options is because I think I will need one that will allow those turbines to work from about 60-150 v at least . Did you happen to notice the volts to rpm plus watts (at open circuit) that I entered above for my 2kw ?
That is kinda weird. Cause if you check their open volt chart I have they never got over 70 volts. So it will be good to see how your test goes.
Hi Tom, not sure if you are referring to the inverters not going over 70 V or the turbines. I will try to post the power curves I have for my 1kw and my 2kw. I listed in a thread above I mentioned the open volt range for both based on their charts. Are we talking about the same turbines ?
Well I did place my the 2kw chart as well but don't know where it went.. So if it is the same charts, I still do not understand your comment that it never got over 70 V. In case I am wrong...Effsun rates the 2kw at 2500 watt @ 28 mph On their chart is shows the 500 rpm which will represent the 28 mph The turbine is rated to cut in at 56 Volt and cut in is rated at approx 8 mph The graph shows an approximate 110 rpm so divided by the 56 V = .51 volts per revolution So at 500 rpm that equals ( .51 volts per revolution times 500 rotations = 255 volts That means with out a load that 2kw turbine is rated from 56 V to 255 volts Now that is my story and I have been wrong lots before.. lol.
