You didn't mention which Xantrex model you have but there are a plethora of settings available on my Xantrex Freedom SW 3000 inverter. It took me a lot of time reading the manual and a few phone calls to tech support along with some trial and error to get an understanding of how the system works and its capabilities. Sounds like you have the settings set in such a way that AGS will start and run the generator only until the batteries complete the "absorption" phase, which usually only takes about 10-15 minutes in my case. If you want the generator to "top off" the batteries then set the AGS to "float" and it will run until completion of the float phase. If you haven't already, you will want to set the low voltage limits which determine how low the battery voltage gets before the AGS starts the generator. The default settings on my system were set up for a 24 volt configuration and I had to make numerous changes. You will also want to set the time parameter which tells the AGS to wait until "X" minutes sustained voltage below the programmed voltage before starting the generator to prevent false starts due to a momentary voltage drop when turning on an appliance.
Additionally, there is another setting which you can determine the max runtime of the generator in case you wish to set a limit. I have mine set to 1.5 hours so that when it's in storage it doesn't run unnecessarily and that seems to work fine. Note however, if you do set up this feature and the AGS system shuts down the generator upon reaching the time limit it does so by sending a fault code which will be displayed on the SCP. There is no harm in this shutdown method but the code has to be cleared before returning the automatic mode. You have to clear the code using the SCP with the inverter disengaged.
Another feature I just discovered a week ago is the ability to limit the shore power demand. I plugged into a 20 amp outlet at a relatives house which was all that was available. Of course, I tripped the house breaker twice before I realized I could just select the setting on the SCP to a lower amperage which limits the amount of power the system will demand.
Hope this helps!
