The battery monitor was the first thing I installed.
... And he might already have Bogart monitor - there is no info from the OP on this, either. If this is so, then adding Bogart controller is what I would do (that is, if I were planning 12V parallel array).
The first thing that I installed, after researching my energy needs and solar harvest data in my area, was 2*250W flat solar and 30A Rogue MPPT with infinitely adjustable and well automated charging profile and very detailed display. Reads V/A in before and after controller, and gives me full report in the evening - whether the Abs was reached and if so - whether it was completed, and how long it stayed in Float afterwards.
The estimate was (given the needs and weather) that it will never drop below 70-75% after dark, and will go into Abs before noon 8 times out of 10 - and it worked. Up to this day I don't know whether I need a battery monitor, and what for :)
