Okay, rickst29, so the MPPT has lots of bells and whistles. How many of those will I need to adjust, to get one to work well with my system? Are they well-adjusted out-of-the-box? Or, will I spend a day reading a manual, then another day trying to make adjustments when the sun is shining?
Getting more charge to the battery in fall/winter/spring is definitely an argument for an MPPT. If I have to make seasonal adjustments to the unit, though, then I would shy away from that.
I read (
what appears to be) a good write-up on the difference between MPPT controllers and PWM. It made a good case for MPPT, in order to optimize charging, but it used a 240w system as an example. Is a 12v battery system really worth the $250 for a MPPT controller?
