I agree Kevin. I emphatically agree that I don't understand batteries and charging!
My newish battery bank was nominally 780Ah when new. The manufacturer recommends a charge current of 20% of the C20 capacity during bulk charging. That would be 156amps. My charger will only put out 125amps. So I'm not hitting the max charge current that my battery bank could absorb and my bank isn't that large, and my batteries don't accept a charge as fast as other batteries.
Lifeline says they can be charged at 5C, or 5 times their 20 hour capacity during bulk charging. My charger can't hit that for just one Lifeline 8D battery.
So far I don’t see an issue with your system. You may not be able to maximize your charge current but you do have close to the largest charger available... Good to go there.
Now lets take your loads and cruising style. Do you anchor out very much? when you do what kind of discharge do you have say overnight?
Do you tend to pull anchor and cruise daily, or do you like to sit in the same spot for days at end?
This will all dictate your battery bank size.
