Not trying to misquote you but these two statements seem at odds.
I know you are planning a significant solar
system to keep things charged but running one bank isn't redundant.
I have 3 G24s split as 1 and 2. On the hook we run the 2 batteries paralleled and usually end up running the house down pretty low. The start battery is always charged to get us going from wherever we are.
Yes - they are all the same (Delco Marine
AGM) and deep cycle batts for the house is recommended but at this point with my small boat simplicity is more important. The batteries are 4 years old and seem to be doing well. I top off with solar
at about 1 1/2 amps.
