I completed this installation last summer with installing a smaller inverter.
We went with the Morningstar SureSine⢠it is a 300 watt pure sine wave inverter and is built like a tank with low power draw and no fan. It is also installed with a cutoff switch for while in storage and a remote on/off switch to shut it off when not needed.
I found that I could isolate one circuit of outlets off of the campers system and I tied thay string of outlets into inverter only power. This feeds the two tv locations as well as both bedside outlets for charging our goodies.
We are really happy with our medium sized solar installation, now to just get to use it more often!
