Hi Aaron, You may want to install a Combox and enable SD card logging. You can log 5 sec intervals I believe. Be sure to power it off of the Xanbus otherwise it will turn off with the AC. If you decide this needs to be done, be ready to sift through a lot of data.
Also, as I recall, the Schneider AGS doesn't automatically decide it should start the generator if the system goes to LBCO too rapidly. This could have been addressed in subsequent firmware editions but I remember this. I suspect that the battery voltage dips enough for LBCO but recovers enough not to trigger start signal after the AC load is shut off. I suspect you may be right, that a large load is coming on and driving the battery below LBCO before the gen start signal can occur. I'd also look for evidence of corrosion, looking for stiff battery cables. You may try turning off all the solar when you are there and turning on all the large loads. Does the battery voltage rapidly crash? If so, do you have some bad cells? Are the batteries super cold? I also echo Rays thoughts of not relying on a generator when the place is unattended to keep pipes from freezing. Most generators will fail under those circumstances at some point.
