Charge controller recommendations
I have a small solar charging system consisting of two 12v 75w panels wired in series and a failing cheap MPPT charge controller. I may be acquiring another identical panel too. I'm currently leanin...

smkettner how complex can the rules be made? I have seen the programable voltage and timing tables in their software, but not rules.
After programming the voltages and duration limits for the phases of charging for my batteries (none of the fixed parameter controllers i have seen meet my battery OEM specs) and especially the temperature compensation factor (again, no fixed units have this quite right, at least for these batteries), I'd start putting in more envelope boundary condition rules that the fixed controllers do not implement, such as charging rules for over 95 degrees out that are above and beyond what temperature compensation does to adjust the charging voltage.
