I would like to add that I have recently experienced a similar situation. Mine is a 50A rig but I use a 30A adapter as were never at 30A sites.
Rig has a 50A EMS (for full protection should we ever visit equipped places), and I have 2x 6V GC batts and a 1800W Xantrex inverter. I have relocated one circuit in the rig and hardwired it to the inverter so the fridge and several plugs run off the inverter as needed. My inverter passes 110v to the dedicated circuit on shore power or fires up when shore power lost. At a few places with low line voltage I wake up to my night lights (inverter plugs) flashing on/off every 1-2 seconds. I suspect that the ATS in the inverter doesn't like the incoming voltage but my EMS that protects the whole rig shouldn't act like that. If it gets low/high voltage the whole coach powers down for about 20 seconds or so. I'm stumped if theres an issue with the inverter or if my EMS isn't behaving like my previous 30A version. I suspect a voltage issue is causing issues with one or the other pieces of tech?? Any thoughts? If I change to a better and larger inverter I would like to power up the entire rig with an inverter (minus HW tank/converter).
