I've been researching this quite a bit for our Voyager Camper. There's a number of resources that show you some easy to follow solar-to-battery-to-inverter setups. Here's one link I pulled a lot of good information on:

Select a good MPPT controller to keep your batteries from being overcharged. The Renogy ones are a great choice. That's what we selected.
Our setup is going to run:
2x 160W solar panels
Renogy MPPT solar charge controller
2x 100Ah batteries
1 800w (peak) inverter for light electronics.
I'll have to look and see if I have a soft copy of the wiring diagram. If I find one, I'll ship it off to you, but there are plenty of great examples on the web.
