Are any MPPT controllers buck+boost?
Apparently some MPPT controllers can boost voltage up when Vmpp is near or below Vbatt. Or do you just wire the panels serial-parallel to ensure the voltage is always above Vbatt is Vmpp can get close...

Right I could just put my two 12's in series and get 24. I'm not yet convinced in the real world for my panels, whether serial or parallel connection would do better. It would be nice to have the option and be able to compare real world performance, if I go MPPT.
