Shawn,
This arrangement allows the use of a starting type battery, which can
deliver high current loads for short time but is not intended be drained
significantly, on the starting bank, and deep-cycle type which are
intended to drain down to much lower level over a longer time, on the
house bank. It would depend your use and on how often you recharge
whether this is important or not, to be sure. And there are now dual
purpose batteries, so it may be less of an issue if you use them.
One other reason for this system is that it prevents the starting
voltage dip from shutting off your electronics on the house circuit,
one of the main reasons I chose this.

I can see why this is superior in isolating a battery/bank, but how
often is that necessary? Is this just to prevent the good batteries
from being drained by the bad one(s)? So if I had multiple house (or
start) batteries, I could just additional on/off switches linked to a
house or start bus, and a switch between the buses? Something to
consider depending on how far I get carried away with my electrical.
Currently I have 2 banks, with room for a 3rd, and just leave them
combined all the time, as they are all 6V GC batteries. If I'm
concerned, I could isolate one bank in case the sun stays away for too
long (and we're not motoring at all), but so far that hasn't happened.
And so far, the only significant load we have is the fridge, with
minimal electronics. Once we add radar, that will change...

Take this opportunity to do away with the 1-ALL-2 switch.

Yesterday, my Blue Sea DC switch failed in a bad way —
essentially the plastic broke and the guts of the switch come
apart causing a flaky connection. Seems this is a common
problem base on this forum:
https://www.thehulltruth.com/boating-forum/853223-blue-sea-battery-switch-failure.html
I emailed Blue Sea and await their response.
Four years ago I replaced the original old Perko switch when I
did a battery upgrade/rewire/shunt+monitor. Now I’m worried
about simply replacing with the same one if it’s prone to
failure.
Luckily this happened at the dock but it could have been
really bad if I’d needed power in a hurry.
I’m now thinking I’ll wire up a “backup” bypass directly to
the starter in case this happens again or for jump starting, etc.
Any thoughts on this from the collective wisdoms of this list?
Thanks,
Jeremy
