My thoughts are you have a converter/charger problem, all other aspects being normal. Your "charger" should pick up all the DC load up to about 75 amps before the batteries begin to show depletion. However, your batteries may have "taken a set" by being discharged to low voltage and not fully recharged and are no longer capable of being fully recharged. The nominal voltage of a fully charged 12 volt battery bank without input or output is 12.7 volts. Turn off your charger, let the batteries rest for a day and test the charge across the entire bank. The surprise voltage you received when your inverter/charger was turned off was likely from the generator start battery.
