Andy, I am trying to learn this stuff too.. I am thinking Leamy needs to take the time and do a detailed thread of installation of pics and an part list on how to install this grid failsafe. I also figured out in good winds to bypass the diode and let the turbine see the batteries and ran only ONE 600 and put out 500 ish watts from it all day and never drained the battery bank down. It trickel charged the bank while maxing out the gt at times..2 gts would start to drain the batteries in between gusts to much..We had 20-30 mph winds with 40 gusts and the little 500s furled a bit yesterday... this worked well to get it in the 40v range.. I had a few times of runaway volts that showed 70v while I was down there and was expecting to hear that cap pop but never did..Think because the batteries were there taking all the true charge and not filling the caps at the time???
Andy,I understand the concept of electric,its just water in pipes with pressure and flow to me but all the components have never been explained to me and I am trying to figure things out hoping someone will feed me the info in the way I need to understand it..I think I am in 3rd grade though LOL
Blue, i did take the time to post layouts with explinations, please goto the wiring methods it's all there. Many different scenerios's for the China GT's including the GTI fail safe system. I have also sent you a lenghty PM explination on how it works. If you have any questions please ask. The diagrams took many hours (take the time) to do. I put the picture for the conatactor up there for Blue to look at it as i was helping him off the forum. Andy that contactor will not help in your situation. Now i removed it but again it is in the wiring methods and also in pictures i have posted. I explain about the fail safe system in my post's with pictures and explain how it works. PLEASE READ. Oh yeah i also have a vid on my system as well. Please follow my work and you will see.
Links baby,,,,,I have never seen this "wiring methods"...dont get irritated,,thank you,,I will get educated and read up on the components..
Thanks Andy. Thanks Blue, my appologies. You know how it goes you post so much to help and get no results. I want you guys's to look at my work and help me make sure it is right. I do not have all the answers but i have presented a very good foundation.
Well I forgot to update from our storm Saturday night,,,I seen the highest output from all my turbines feeding into 2 seperate circuits of a combined total of 2,134W of a high blip!! Slowly progress in the right direction
New! Power jack ,1200w grid tie inverter,DC50-100V,AC90-130V,solar panel http://www.ebay.com/itm/New-Power-j...285?pt=LH_DefaultDomain_0&hash=item2eb81c9035 I want to test this so bad,,all donations will be accepted in the name of science!- I emailed Ningo and am trying to get sun-g to offer either a 40-80v or this same unit...
Finished up the controls for a 5kw Talon wind turbine with an Aruroa 6kw inverter 40 ft monpole tower. 5kw turbine. 750pound gen head. Aruroa 6kw inverter starts producing at 50v What a gret inverter if you can get one. Hooked it all up and it worked right away. Seen over 1kw out if in about 12-13 MPH winds. Man talk about go big or go home. This turbine runs up to 260VDC at about 240 rpm to get 5kw out of it. Very simple controls, dump load control, disconnect, inverter, another ac disconnect, grounding and then to the panel. This is why i wish i never bought low volt turbines. High volt is the way to go even in the 1kw class for grid tie. We all try to get blood from stone from the little turbines. This is how simple it should be. Man, how much i had learned so far. LOL Thought i would share
Wow Leamy! You get to learn how the best of the best are installed and work! Someday $$$ 5kw's with auroras. Yes allowing the turbine to get up to speed before the load is the most critical part of efficiency... Hell I believe once someone plays with a higher voltage gt and run 2 750 turbines in series will show that lower wind watts and very little loss of high wind watts can be achieved .. So much testing to do and so little money
I hooked the two I have in series and it loaded the turbines down too much. That was using the 22-60 volt GTI.
So imagine one of those 50-100 gt's tom..With no load 50 would be easy to hit with 2 turbines and you would not have to worry about 100v overvolts I think...There would be less line loss with higer volts which would mean greater watts at the end! I want one to put this 2kw on..In light winds with no load it ramps up to 50 easily. My anameter is broke,caught my harness on it a few weeks back and broke off a spoon but my guess is ten mph and (10.6ft diameter blades).. I think two of those would be a perfect match for it in the future.. I have a contractor switch with a n/o leg coming to test out the instant grid down braking system..
With a 50v-100v grid tie then higher volt/lower amp motors would actually do a little something especially if geared for the begining experimenter that has very little money...
I had found that powerjack was the most inefficient of the gt's in the begining but now are the only ones to offer this input voltage..Would love to rewire my solar next year for these..Higher volts IS ALWAYS better.
just won a 1200w 50v-100 GT for 205 shipped,,he will not be happy! I wrote him to let him know that I will be helping to test and spread the word on these units so he dont stiff me.All his buy it nows are @ 350 ..Need one more for the 2kw.
Blue good luck with your new inverter. Just becareful, from my experience those inverters are not rated for quick fluxuating volatges. They like like steady qradual power from solar panels. They don't seem to convert the power real quick for a turbine. Hopefully your finding will yeid better results then mine considring you are using them at a higher voltage. Good luck.
I love these new power jack 50v's.. I did blow up a 22-60 trying to think the 1200w 50 v would keep it capped but we had 25mph winds and I see that along with 1 600w 50v coming I will need another too and I finally will never have issues again like how safe the 2 500's are now.. I did get to test my grid braking switch today at 144v(I am so thankful the powerjack didnt explode caps and will not let this situation happen again!)..enough grid ties WILL cap voltages,,that has been proven and now if the power goes out IT INSTANTLY SHUTS DOWN THESE 10.6 ft blades!!!!! ... The destructive learning curve is done for me now I just need a few more PJ 50v's.. I got a quote from Laura for 1kw 48v so it will be 50v GTs from here on out..The book also has rough english but shows how to test all the main components on the boards for them to be repaired easily...
