A converter/charger converts 115 volts to 13.2, 13.6, or 14.4 volts (depending on the make and model) to charge the battery and run 12 volt devices.
An inverter uses 12 volt battery power to make 115 volts AC to run 115 volt appliances.
Many RV's have a disconnect switch to shut off most 12 volt appliances. Certain 12 volt devices are not connected through the cutoff switch.
Some RV's have an additional disconnect switch near the battery that is a true disconnect. When the true disconnect is opened, a fully charged flooded cell battery will last in storage for 3 to 6 months. An AGM battery will last 6 to 12 months.
