1600whr is the approx total use in 24hrs (when I say day, i mean a 24hr period)
if I get 1500 watt hrs in the summer, the generator or driving only has too make up the difference
i'm getting over 1kwhr per day NOW on sunny days, 1200+ the other day
but that still leaves 400-600whrs to made up by other fuel burning means
I know when it's 100+ F, i will be parked in the shade and running the A/C
but I hope for the solar charging to Hit a break even point before that becomes necessary r
the additional 4 batteries will add 320 ampHrs of capacity for a total of 760 ampHrs, this will hopefully make the solar charging and converter charging more efficient and extend the life of all batteries involved
