I'd spend the $150+ difference in my suggestion on another battery and not worry about how many AH used.

It doesn't matter how many batteries you have if you don't know the state of charge and if the batteries are being recharged adequately. You'll wind up with lots of batteries that live a very short life. Chuck

I've been able to figure that out with a $5 volt meter for the last 10 years.

+1 for just using a voltmeter and a little thought.
More solar, better converter, more battery would provide more actual power.
Can't imagine having a monitor system that costs as much as the batteries. Maybe 10% of the battery cost is the value point to me.
