I am very confident using the OB VFX AGS settings for OFF GRID situations. Be very careful using the flex net to s/s your generator. anytime this unit is disabled it will reference the battery voltage at that point as the full battery set point. There once was a time where OB suggested that one uses the AGS on the VFX only. IF you do use the FNDC install a 10 amp breaker to allow you to disable the unit, after you have removed the cable to the hub. Fully charge your batteries using a refractometer then repower the FNDC. otherwise you WILL have all sort of issues. I have always found that the issues related to no start w/ the OB is either incorrect user settings , out of date software, or and this has always seemed to rectify the issue is to REPOL the mate once every few months. AGS /gen start wiring into the MASTER VFX which should be located at the BOTTOM of your stack. ALWAYS install a temp sensor.....battery thermal runaway is NOT a pretty scenario!
