    Re: MPPT controller for wind turbine

    I see you have a 48 volt battery bank. so you may run up against the outbacks 140 volt limit in theory this wil limit you to about 2.5 times the turbines rating. The thing i noticed with the Classic is i am able to let the voltage really climb which let the rpms climb making the turbine much more efficient.
    I have routinely seen 3 times the power from my turbine and once we get the Clipper installed i am shooting for 4 times. i understand that the rpms will be up there for 4 times the power but they will still be within a safe range. ultimately i will limit rpms with the Clipper to 650 which will give me a boost of about 3.5 times the power.

      The Midnite Classic is indeed close. We are beta testing them now. Two of the present Classic beta sites are already doing wind. You will be able to see live real time data logged sites in about 3 weeks. There are to be two different Hugh Piggot designs 1000W and 2000W (both Hugh Piggot designs), one Kestral 110VDC and the last wind beta site will be switched between a Chinook 200, a 48 volt Bergy XL1 and solar. Other classic beta sites are data logging strictly solar (boring, but they are performing well). Wind is a lot more fun. The last beta unit is slated for Australia where it will be charging a 120VDC battery bank. We do have a Clipper to go along with the Classic for wind applications. The Clipper limits voltage coming out of the turbine, or current or RPMs or all three. The Clipper also slows the turbine down when batteries are fully charged or in the case of a storm. One upcoming beta site will have two identical 2KW turbines on two identical towers. One turbine is hooked up direct to the battery bank with a regular dump load, the other has the Clipper and 250 volt Classic. It will be very interesting to see how it all works. We do not have enough Classics to parallel them at this site, so it will be interesting to see how much power we can control? The Clipper will aid in this issue when max power of the Classic is reached, but what happens if we reach the max power of the Clipper? The intent is to slow down the turbine to reduce power output in this case. If all works according to plan, you will see it on our website. If it all goes up in smoke, it will be a little longer until you see it. The project is scheduled to be installed in about two or three weeks. Every wind turbine will have different characteristics. Some will be easy to control and some may not be stoppable. boB and I have been designing and manufacturing power electronics together for over 30 years. The Classic and Clipper are for sure the most challenging and also the most fun. Designing inverters and charge controllers at Trace, Xantrex, OutBack and Magnum had its rewards for sure, but the stuff we are doing at Midnite is really over the top.
      The turbine described in this thread will have similar issues regarding to power output. MPPT does really double or triple the power output. That is a problem with controllers that are only good for 3 or 4 KW. Boy this is going to be fun.
      I know Niel will be disappointed, but the Classic and Clipper are not talking to each other yet. That should come with the next board design.

        That sounds like another feature Voice Recognition? no nead for network cables between controllers:)

            Wow ! What about 96V or other "odd" (36V) voltages? Do you have inverters that will run off 120VDC - or how is that used ??

              Robin - we expect to have an in depth review here first when it is released

              The only controller in the world that you can argue with?

                  Oh my goodness ! That post was quite a while ago.

                  For real units and real-time data logging, go o www.midnitesolar.com
                  There are a few out there. The one in Oregon is off line at the moment but Jason is going to put his back up online as soon as his arm heals a bit more.

                  Otherwise, wind is working very well.

                      Re: MPPT controller for wind turbine

                      Indeed Mike, I have been waiting for one for so long (really only about 5months) that I went ahead and bought a xw 60 2 weeks ago. I still want the classic though so I will wait again. I am not sure I can hole out for another 5 months though. I would have loved to have two of them (one for wind and one for solar) so it would have to be the xw for solar and the classic for wind...unless i sell the xw...hmmm.

                      Cheers...

                        I would like to give you an exact date but cant do that. I can say boB is reallllllllly close or even done on the last board "Right boB?" so we should be building and shipping a bunch more beta units real soon. Keep an eye on www.midnitesolar.com for updates and info on the beta test program.
