Yet Another PWM vs MPPT Comparison Test
I was able to run a couple tests with blue sky at same time of year and location as my test from two years ago (flat, tilted, tracking results one) that : A. compares PWM with MPPT, and B. compares ...

How about if the idea is to run loads all day you get the batts charged up using the high set point at 14.8, then add the loads to knock that voltage back down below 13.2, then reset the high set point (not the float setting) to 13.2 so it doesn't go back up on you when the loads are not so much from time to time?
I believe setting the "high point" lower will make the controller kick out of MPPT even quicker.
I do run quite a bit of loads during the day and it does hold the voltage down which keeps the controller in MPPT for much of the day. Powering loads during the day is nice in that it's "cheaper" power. By that I mean that you don't have the losses of charging/discharging the batteries. The power goes directly to the loads.
It's a balancing act though. You don't want to demand too much such that your batteries don't get recharged. On the other hand, the more you use for "free" during the day, the less you have to put back in the batteries the next day.
