But that means remember to watch battery levels for both and then manually switching daily.
Yes, manually switching them for both discharge and charge....probably a horrible solution.

Once you determine what your daily draw will be I would invest in the right amount of watts for the roof and T-105 batteries and forget the dual banks unless you do something automatically. I know you can get solar charge controllers for dual banks but why go through the added expense of that and an isolator when you can just sell your group 27 and get the required number of 6v batteries. I sold a pair of well cared for Grp 24's for 60 bucks...we were both happy with that.
