If I understand what you are asking, you don't need the INVERTER when plugged into shore power as that IS your source of 115 VAC and your CONVERTER should remain on to provide 12 VDC to power your onboard things.
If the INVERTER is turned on, your CONVERTER should be turned OFF as you are creating a loop [inverter powering converter that charges the batteries that run your inverter.] Big problem!
