My opinion is you are putting in a lot of components that you will not use. The stuff you are installing is mostly used for boon-dockers who spend days off the grid. Also the more electronics you install the more things that will go wrong down the road. I once installed an inverter . It was pretty much a waste of money. When it wasn't beeping at me that there wasn't enough power in the batteries to run what I wanted to run it would just down right not work. So simplification just don't use one. I rarely camp off grid. When I do I just use 12 V power and a small generator.
