Larger inverter needed for microwave and toaster but with just 2 batteries they will get depleted pretty quick attempting to power high amperage items even for a few minutes a day. Running tv and charging small devices can be done with existing inverters.
Good idea to have at least 100 watts of solar per battery so on a sunny day they recover most (and maybe all) of the consumed amphours depending on how much they have been depleted. Out west where we camp most often we tend to have good results with solar replenishing our battery bank.
We find having both solar and a generator is the best of both worlds and makes for worry-free camping as it pertains to enjoying all the comforts an RV provides. When camping in good weather and mostly clear skies our genny sits idle except for the few minutes each day where we require 1K+ watts.
