A good battery monitor like the Victron BMV-600 should be the FIRST money you spend in any battery/charging system upgrade. I usually recommend this to be installed at least a month before the rest of the system is decided upon so you can gather actual usage and charging data before making a "shoot from the hip"/"kick the tires" decision..
I see people chronically under design and chronically over design systems because they had no idea what was/is really going on. The money spent on a good battery monitor is usually free, in the long run. Get one, two three or four extra years out of an expensive battery bank or buy the right alternator vs. the wrong one for the application and the cost of the monitor is negligible to free..
