there can be several differences in how RVs are built, when it comes to Inverters:
- some basic smaller inverters are only for a dedicated outlet, such as for the fridge, and don't provide power to anything else. The Converter, then, provides two things: Battery charging when on shore power or generator power, and 120v to 12v 'conversion' to the fuse panel, for all of the 12v devices and appliances.
- some others are similar, and larger, and add a few more outlets to the mix...
- some, though, are considered 'whole house' Inverters because they are wired INTO the Main Panel of the RV via a sub-panel, where not only are those outlets powered by the Inverter, AND by shore power or generator power, but the Inverter also has an integrated Battery Charger - in these builds, a Converter is no longer needed. Any 12v devices are powered by the batteries, just like in any RV, but when the rig is plugged into shore power or powered by the onboard gneerator, the Battery Charger effectively replaces the used battery power used by the 12v devices and appliances.
so, in essence, the Inverter/Charger replaces the need for any Converter.
My rig has no converter.
