question on interpreting MPPT controller display

Yes, jack up the voltages to meet the battery specs. It can be an issue for how long the controller stays in Absorb at a high voltage, depending on the scenario. Some days you want to stay at 14.7 as long as possible while on other days you want to drop to Float earlier in the day.

If you have open flooded batts you can always add water if Absorb is on too long, but if you have sealed batts you need to pay more attention to what each day will require.
