IMHO nothing wrong with those numbers for a rig that does not endure off grid camping longer than a week (more or less). For entended generator camping 14.8 volts should persist until the batteries start bubbling lightly then defeat to float. Your numbers would require a generator to run 9-12 hours to get a full charge.
Your battery is a hybrid 2-3/4% antimony / calcium negative plate unit. I would limit max discharge to 60% remaining. Drawing deeper causes charge rejection. JC likes power pedestals. The hybrid demands a higher absorbsion voltage limit. Ypur charger algorithim is very light on permitted absorbsion. Is there any way to reboot the charger protocol? Tjat would make things easier.
