Your main DC breaker is probably a 50- or 100-amp breaker. The inverter would ideally be wired THROUGH THE APPROPRIATELY SIZED FUSE and through a disconnect switch, directly to the main house positive bus. As your house batteries are apparently split, this makes it a little more complicated. It sounds like you may need to sort out the battery wiring, as it’s a bit unclear; then decide if you want to rewire to simplify things.
My recommendation: put all your house batteries in one large bank, with one on/off switch; keep the start battery separate, also with one on/off switch; consider adding an emergency cross-connect switch between the two; and replace the (probably diode-based) isolator with something like an Echo-Charge to keep the starter battery charged up. All charging sources would then go to the large house bank, including the alternator and your shorepower charger. Make sense? I think I have a Blue Sea Systems model 8280 battery switch panel http://www.bluesea.com/products/8280/Traditional_Metal_Dual_Bank_Battery_Management_Panel that would work for you; I’d sell it at less than cost, if you’re interested. Just add an Echo-Charge and the appropriate cabling and fuses and you’re good to go.
