Be careful..... Solar can suck you in.
While the kit you listed may keep a single battery charged, the inverter will use more battery and leave you looking for an upgrade. This system has no room in the components to add more panels.
I'm guessing the inverter is just a modified sine wave, so nothing special.
Don (Mustang) makes a solid recommendation in the Renogy starter kit. I bought a 200 watt starter kit a few weeks back and used it for 10 days in Glacier to keep my two 6 volt batteries charged up. Worked wonderfully. I didn't need to worry about being at the campground for generator hours to charge. I used them as portable panels (laid flat or leaned against chairs) and they kept the batteries in good shape the whole time. I'm planning to make a few adjustments and additions in the near future, such as a stand for them and 25' extension cord for them. Also planning on adding an inverter to run the TV and other light items.
I would highly recommend!
