Hi,
The point everyone is missing is that lead acid need to be charged to 100% as often as is humanly possible (without generator use).
Li has no such constraints--so a couple of days of bad weather don't matter. Of course the battery management system might leave you "hi and dry" (which is a good thing given the price) as Li hates being taken to zero volts.
The same is true of SiO2--and as I'm very much part time again--I'll go for a 600 amp-hour bank and probably never need a generator again. The two advantages of SiO2 over Li are cold and zero volts without much damage.
BFL13 is a master of recovering flooded Lead Acid batteries--but he did not have much luck with AGM.
Here is an example of this month from solar, just the beginning of my psoc use for winter. Dec, Jan & Feb the periods of psoc can extend out to 21+ days before a string of poor solar days force a 2 hour generator run give the batteries a couple hundred ah boost. 40 days was my longest of psoc use. This will be the 5th winter of this kind of use.
