The converter has wires that are designated for the 12 volt appliances and a "hot" wire that goes to the battery. I understand the 110 volt wiring system and that the converter reduces the shore power 110 volts to 12 volts then to the appliances via the above mentioned wires. My question is about the "hot" wire going to the battery. Is it designed to only charge the TD battery or does it also allow 12 volts from the battery to go back into the converter then out the 12 volt wires. Do I need to design a system for the 12 volts being supplied by the battery or will the converter wires work, even though it is not plugged in to shore power?
