Recommendation for amp/hour monitors?

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.

I did that for many years because I developed a seat of the pants idea of SOC with various loads. Morning with minimum loads was predictable.

But with thoughts of solar I wanted to know more and I got that. Not only battery information but accurate load information just by turning a light on/off and noticing the amp difference. So I was on my way to determining a bunch of things - like why did my 100A Magnum inverter only produce 80A (yes I accounted for house loads). So I called Magnum for an appointment for them to fix it - turns out no fix needed as with 117V AC input 80A is good. One of about 6 "cost design trade offs" I was to learn about - And another one is that while charging 80A the display (non BMK) shows 100A, just by coincidence of course. :h

And now with solar it's a even more valuable tool. If only they would upgrade to predict how much solar power I'll get that day...:B
