Our start and house is one combined bank of 2 8Ds. Sub-optimal but IG tradition. Genset has separate N150(?6D) battery,so it and genset are backup if the dual use bank gets messed up(which it hasn`t).
Genset batt has its own regulated solar panel so it is good backup, otherwise it only gets charged when genset runs. I like the self contained stand alone backup.
