Charging a Battery Bank
I am planning on upgrading my batteries to 4 6v batteries wired in series and parallel to have a 12v system with plenty of Amp Hours. There is a ton of information on how to wire things up but nothing...

That is a good set-up for the camper, with the solar, inverters, converters, monitors, etc.
In the photo it is not clear where the PM-75's chassis ground goes. It is supposed to go to the rig's frame independently. The input 120v cord's green wire goes on the chassis inside and the chassis external 'ground lug' connects to the rig's frame. AFAIK it is for reducing noise on radio and TV. The converter works ok without it.
I am not sure what can go wrong if the converter's chassis ground gets mixed in with the output neg DC down the line somewhere on the way to the frame. It is a big no-no to bring an inverter's chassis ground around to its DC neg input, and get to the frame via the battery neg to frame.
