Are you already assuming lithium in this statement? Because with LA don't you want 2x your max drawdown available, so that you don't run below 50% most days? That would mean 200 AH is what you should spec for?Esus said:So I'm looking at ~60 ah a day max and will more likely be in the ~50 ah per day range most of the time. I'd like my system to run for 2 days without any driving or charging, so ideally I'd like a battery in the ~110 ah range.
That's what I assumed for my setup, and your power need calculations and desired 2 day interval are the same as mine.
