13.2 v should charge the battery, however it will take a long time, think days.
I read in another forum that the Todd Engineering PC45A is a piece of junk and should be replaced. I have no idea how valid this statement is.
With the converter running, connected to shore power, it should be able to supply power to the RV and charge the battery, up to 45A. Maybe it can't supply the current you are using so the voltage drops and the battery doesn't get charged. If you check the voltage while using a lot of 12v current that should show if that is the case.
Sorry I can't be more helpful.
Thanks so much for all your time and trouble. Will try all your suggestions.
