Air 30

Will I be able to use my Air30 12v to help charge my 24v bank using my Classic 150, or would I need a converter?
I did read the Classic will convert 24v to 12v, but did not see it the opposite way.

    Welcome to the forum.

    The answer is "no"; you can't up-convert with a standard MPPT charge controller.
    You could use a DC to DC converter to increase the Voltage (at the cost of current of course), but frankly it would be a bit unstable because the turbine's output is variable and the converters are meant to have stable input Voltage. Frankly more trouble than it's worth to try.

    Apparently the Classics can be setup to boost voltage, but it hasn't been implemented, I don't know to what extent, boB has said he might spend some time on it, I think, but his plate is pretty full. You might ask over at the Midnite forum..

    Here's one of the threads. Doesn't sound like boB has a great interest in working on it at that point. Of course that was back in 2011, I had read something more recently, but it's not of great interest to me.
