Need info on small solar setups

[Durian Fiend]

I plan to go to LiFePO4 batteries.  I regularly kill my lead acid batteries.  A great thing about the LiFePO4 chemistry is that they actually like being partially charged.  A lot of the hassle of lead acid is trying to avoid prolonged periods of partial charge.  There is the temptation to do things like turning off the reefer at night and then the next morning maybe running the generator if it is cloudy, only for the sun to come out in the afternoon.  With lithium, just run the generator when you really need it.

Earlier you mentioned never running out of power, so how are the batteries being killed?  

With enough panels I don't see a need for a generator at all, unless it's for special projects requiring a lot of extra power.
