Seems like the cool kit for off grid solar is 48v. There's some 24v, and almost no 12v except Victron.
I've been seeing these all-in-one systems (Inverter/charger/MPPT/transfer switch) such as this one reviewed by Will Prowse.

3000w inverter, 80 Amp charger, and the solar controller can take up to 5000w/500v of solar panels. It's around $700. Comparable victron components would be 5x that plus a lot of space a cabling.
Balmar now makes a 48v alternator ($2600- ouch).

Granted it would mean a second alternator for most boats, but the components and price points seem to be approaching usable for boats.
Server rack batteries are getting pretty afforable and are designed to integrate nicely all-in-one inverters. Seems like this is coming of age. Anyone thinking of a 48v house system?
