I have had a Midnite Solar Classic 150 for two years now. Installed around 11/2017 and has been running fine. I have 169 KWH total for the two years and hope next year is better. Aux 2 has been controlling my 3 phase SCR's . And has been working great. I finally got a working wind curve for my (2) dual core generators. Just make sure in the advanced config menu. That you set max voltage to the max input voltage from your wind curve. Or your AUX will activated much earlier or not at all. Also below in a text file is my current Wind Curve. (UPDATE 2020) I had a few days of good wind that had steady but varied in speed. So here is my LAST wind curve.
