Do you consider it better to have one or 2 sets of house batteries?

" The Preferred System

The Preferred System consists of a single house bank, and a dedicated
starter battery for all engines. A separate generator battery is
sometimes present. "

We have two banks for much the same reasons as Rosalie, but for our
moderate needs that are now mostly handled by solar, I'm tending towards
a smallish battery directly connected to the alternator with a
paralleling switch if I need to charge the house.

That would make it impossible to fry the alternator by switching the
wrong way by accident. In addition, I could shorten the primary battery
cables considerably, making it more likely that we'll start under all
conditions. The only downside is if the starting battery dies, but since
it won't usually have any but starting loads, it'll last a longer; I've
had original-equipment car batteries last a dozen years.
