MPPT controller setup question
I haven't received my Tracer 4210rn charge controller yet but I downloaded the manual and it seems very straight forward except for the timers. There are two timers I have to set one is "load will ...

The charging profile is not adjustable but the voltages are temperature compensated.
The charging profile is the same as my LandStar PWM controller, also made by EP Solar. With Wets the voltage climbs to 14.6v then holds there for a fixed 2 hr period, then drops to 13.8v. (then it gets dark, voltage falls, and you start over in the morning) That worked ok for the solar conditions and battery bank/panel wattage ratio we had then.
The 100Voc limit is good for allowing 12v in series if desired. Note the warning up front about never going over the Voc limit and to use the panel spec's temp coefficient for Voc to get the Voc at the lowest ambient you will be camping in. It mentions a red light and a PV over-voltage disconnect feature. IMO don't push your luck! :)
