Going to try one too...my pos so-called mppt controller never even goes into 14.4 boost even when my battery is down to 12.2 volts...will be fun to try this.
What exact controller do you have? Some cheap ebay ones marked MPPT are "fake MPPT" in that they have no buck to them. Those are ok as ordinary PWMs though. Known here as an "RJ Special" since he introduced us to those models :)

I'm guessing my controller is a fake mppt, was a $20 ebay special!! I am looking at this one now cause all the terminals are on same side, like my controller.
