Need to separate the batteries and test them individually. Then reconnect verified good batteries to the inverter and monitor the charging voltage is correct based on the settings. Post the results.
When you say monitor, are you meaning from the Magnum's remote screen, or with a multimeter, or something else? Just curious so I approach it in a recommended way. (I'm handy with a multimeter, but not a pro.)
Since you are in diagnostic mode I would verify with the multimeter direct on the battery terminals. All batteries should measure virtually the same voltage once all connected. Then compare the reading to the Magnum remote. The comparison should be within 0.1 volt. Possibly a little more if heavy charging or heavy load on the inverter. Once you establish the remote is reading same as the battery then you can trust the remote to be reasonably accurate.
Electrical issues are diagnosed by separately testing component functions and verifying operations of each component.
