I sort of regret going with a 48V system because it prevents me from plugging in a lot of devices directly to the battery. I have a few USB-C PD fast charging modules I would want to use directly. Also a battery-to-battery charger such as an iCharger or ISDT product won't do 48V as input or output. Not a big deal if you just want to connect an inverter all the time.

A more relevant issue may be that your solar panel's voltage will have to be > 48V. Actual voltage will depend on your MPPT charger. Victron seems to require battery voltage + 5V. Mine requires a minimal of 60V from the panels, so I have 3 24V panels wired in series, and cannot downsize.

I think 24V would've been a good sweet spot. The USB-C PD modules only step-down, so they cannot output 19V with 12V power.
