Help with custom Morningstar Tristar PWM setup

Hello. Can I get some help setting up my Morningstar Tristar 45 PWM controller with custom setpoints? I have been using it at the stock 14.6V absorption voltage profile with temperature compensation...

OP here.
I have my charging setpoint at 14.25V. HVD on the charge controller is 14.40V and it seems to work a bit faster at clamping down on the voltage spike. But I still get faults under the right circumstances. My inverter tripping at a low HVD is my only issue in my opinion. Claimed 15V but it seems to trip at around 14.8V. Everything else works like it is supposed to. My system may have been overcharging the batteries all their life so they may compromised as well.
