I'm a newbie at solar, but lately have been watching the system closely; following what I've learned in this thread. I've got 800AH of AGM batts and have the Magnum MSH 3012. When I'm down to about 6-8 amps coming into the bank, it reads 100% on the SOC, but it stays on float, when I'm on solar (no generator or shore power). When I plug into at least a 30 amp shore pedestal, as I am now, the inverter's display will ultimately report "full charge", with DC amps coming in at .5-1.5ish.
Manual says "full charge" is just a maintenance mode after 4 hour hours floating, in which the charger is turned off. The charger monitors the batts and at 12.7, kicks back into float for another 4 hours.
As long as the batteries are completely full using just solar on the last 5%, I don't care if they get into "full charge" or not. I suspect "full charge" won't happen boondocking, because the batteries remain in use, with respect to amps In/Out, so the batts don't get 4 hours of floating.
