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 ...

Only start of Abs stage is based on voltage. Termination of Abs stage is based on current and/or time, while voltage is kept constant.
Battery needs to get to V abs, so - yes, with loads it might have difficulties getting into Abs, there is no other way to do it. Not too many MPPT would require a shunt on battery to measure current. Somehow my controller has a solution for measuring current without shunt - and for $400 less :)...
I agree with SMK, 600W solar requires 40-45A MPPT. 60A would be overkill. Why settling on 96A Midnite 150 - I don't know, but hey - whatever makes man happy...
