You are not going to be able to run your AC on solar panels mounted on your PUP. An 80W panel will provide about 5 amps in full sun. For a mid summer day in full sun you may get 40AHr. into your Battery in a perfect situation. This is why you panel will not fully charge your two batteries. Lots of choices of inverters, remember for each 1 AHr of 120VAC power you use your solar panel will need to replace 10AHr of 12VDC power.
