Calculate your ampere hours

total dc loads (dc wh/wk) and ac loads (ac wh/wk)_______________________1 divided by
battery voltage_________________2

Add up all of your dc loads (dc wh/wk) and ac loads (ac wh/wk)

Enter the voltage of your battery bank (12, 24, 48 volts etc)

Divide line 1 by line 2 to calculate your ampere-hour requirement per week.

Divide line 3 by 7 days to calculate your average amp-hour requirement per day.
