Prosine 2.0 will not reset.
After 10 years of faithful service my Pro may be done. I have an error "Prosine internal error #xxxx" on the panel, then "attempting to restart".. but it will not. The inverter switch is on, and ...

I thought the problem is in recharging the tapped 12V string because you will need to overcharge the non-tapped 12V string in order to charge the 24V bank with a 24V charger.

Exactly. Tapping only part of the series string for output means the cells will be wildly out of balance every time they are charged, cooking and ablating the ones not tapped for 12v and undercharging the ones that are.
You could get closer by having a set of switches to let the banks be series parallel for discharging and 24v for charging, but there is still the imbalance while charging to deal with.
A cool system would use 24, 36 or 48 v for the big draws natively, and have a smaller DC to DC converter for the rest. You'd basically have 2 DC systems in the house.
Electric hybrids generally find it cheaper and more efficient to just keep a small 12 v battery for the 12v loads and put heavy loads against a different, high voltage bank. This would not be all that hard. Think how small your 12v battery could be if it did not run the furnace, water heater, fridge, inverter...etc and only had incidental 12v loads.
