Replacing current 30A with MPPT controller - make sense?

Some of you have followed other posts of mine re: solar, and satellite, so hope this additional inquiry elicits similarly helpful info... If I knew then what I suspect now, I'd have had the Dealer ...

Only in severe cold, in warm/hot enviroment PWM=MPPT @12v, when ya use higher voltage panels or series them then MPPT is required. pwm is not comparable to mppt with higher voltage panels or series panels.

it's your money, a newer controller may have more features that could be of benefit.

Panels get hot and their max power goes down with mppt.
