Hi Fred,
I assume you mean "inverter", not "converter". An inverter is like a converter in that it generates 12V when plugged into a 110V power source whether a power peg in a camp ground, or when running the generator. But an inverter also generates 110V when operating exclusively off the pair of 12V house batteries.
Phoenix USA started installing inverters, not converters, in 2005-2006 as an option. 2007 was the first year the inverter became standard equipment on all PCs, unless deleted by special order request.
The first inverter was a Tripp-Lite 2000 watt which was installed 2005-2006 to 2009-2010
The second inverter was a Xantrax 1800 watt which was around 2011 to some time more recent.
I've lost track since. Actually I thought the factory was still installing the Xantrax, so I am surely outdated on this. Hopefully someone else will step in and fill all my history holes.
Our 2007 Tripp-Lite inverter has user-modified settings. For example, I had to reconfigure it when I switched from conventional lead acid to AGM batteries.
