MPPT Controller Selection
Seems like a good time to post this question, on the heels of Mex's post about the import market... I need a 60a MPPT controller. Debating between the Morningstar Tristar 60, or the MidNite Solar ...

Switching on amperage is rather imprecise while the RV is in use.
Example if you drop to float at 1 amp but the RV is using 2 amps you are back on the timer anyway.
That's why I set it to 2 amps while in use :) , and the timer to 90 minutes - seems more reasonable than 120, with my shallow cycling. This is when it usually drops to parasitic loads level, ~80-100 minutes.
While in storage, I change the current to lower value and don't bother to change the timer because the current drops so fast that it transitions to Float after few seconds in Absorption.
