Wait a sec! My 12v system has 0.6v drop when pulling 120 amps from the 450AH, whatever , bank.
It does not matter what the starting voltage is, it drops 0.6v so from 12.5 it drops to 11.9, and from 12.2 it drops to 11.6 (as seen on the Trimetric) so right away the percentage is different within the same "12v" system. the inverter will alarm at 11v--it doesn't care where you started from.
EDIT-Ha! his 24v inverter will alarm at 22v, same as a 12v will alarm at 11v. So how do you get a percentage difference for low voltage out of that?
I know it's late and I need my meds... but I'm not sure what the inverter has to do with it though ? I gave you the % drop based on nominal batt V :?
