The AC300 will not allow me to charge it when i plug it into an A/C outlet when generator is running. Any ideas on why it wont charge.
Hi @dean.mooney
welcome to the bluetti community forum 
You mean, that you want to charge you AC300 with a generator? In this case, please activate “Grid Self-adaption”. Also make sure to use the AC Charging cable from the AC300, plug it in the side of the unit and tie it for optimal contact.

how do you enable it on the console? I tied on the app and it keeps going back to disable
I think you only can activate this feature in the App. If you are unable to activate, there may something not right with your unit. But cant really tell, what it is.
The Bluetti Staff returned on 4th February. They may can help you better with this case
