Prosine 2.0 will not reset.

Not sure about sag under load comparison to hit the low voltage alarm, but I see on the specs of a 12v vs 24v 1500w GoPower inverter, that

24v input 21-30DC with 21 low alarm (range of 9), and
12v input 10.5-15DC with 10.5 alarm (range of 4.5)

With 12v, voltage sag relates to size of load wrt the battery bank size and battery type. Don't think the inverter size matters if it is enough to run the thing and wired right (??)

So with same battery bank only wired as a 24v and the same load, do you get twice as much room for sag like the specs show, or is the sag twice as much and you come out even?

You come out even, although you gain some useful power with 24V by cutting the Amps in half. This means less % voltage drop at 24V. You can verify this by using a wire size calculator.

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.
