I am hip deep in this LI battery thing right now. A very large advantage is the ability to use nearly 100 AH of a one hundred AH battery. Much better than the useful AHs I get from my two group 31 AGMs.
BeerBrewer, I am assuming you mean 30 amp hours from a one hundred watt panel. I typically get 6 amps from mine, and I have three of them on my roof right now.
Also, run your fridge on propane if it is an rv fridge. If you are doing that, then 150 AHs seems high. I typically use about 50 to 60, depending on the temperature outside. We are pretty easy on power, but we don't use flashlights inside, or not watch tv because of power. DW told me she wants to be able to use our 5er without having to start the generator, but she will if she has to. I have been making this happen, and have two hundred more watts of solar to get mounted on the roof.
Don't forget an inverter for the tv and dvd if you need it.
