Wiring from LV5048 to breaker box for 50amp service outlet

[jimjones26]

With my 6 test panels, everything is working good. The only thing I have noticed is once the batteries are at full charge, the charging led on the lv5048 goes solid, and the batteries start to discharge, even though there is plenty of solar from the panels to run the loads. I am assuming I have a setting wrong, but I am not sure which one. I also want to make sure the inverter will stop powering loads when the battery reaches 51.2 volts, as it is a real pain to try and charge my batteries if they go down far enough to not be able to power the inverter on. I don't see a way to accomplish this though?
