Also, some genset/house connections have the incorrect wiring nuts installed in the junction box, and they get lose, this can cause a fire, check those for that issue.
When I disable the charger (because I an tired of that solenoid in the back clicking, and don't remember to turn it back on, and if it's close to quiet hours set in the system, the generator AGS system realizes the batteries are low and starts it up. Just leave the charger enabled all the time and this won't happen unless you lose shore power which happened to me.
