solar question

hey sorry, I should have been more clear. I will be using the yeti as backup electricity, I was forced to move into the motorhome several months sooner than planned, so I picked up the yeti to have some electricity vs none. I am building it as a standard RV to run my 12v stuff(fantastic fans, lights, I think my hot water heater connects to 12v), and 120v outlets inside/out. I called it a converter because thats what they are called, progressive dynamics and a few other companies make them its where you plug into shore power and it charges batteries while powering everything 12v and 120v. all I need to know is if I need a separate inverter aside from the circuits from the converter?

the yeti will be backup, and I will be running a standard rv setup. do I need a separate inverter for the solar? or can I tie it (charge controller/panels) into the rest of the system.
