GL: Battery-inverter-charger questions

[Jim Fidler]

Your refrigerator will likely be the biggest problem, especially if 
you don't have a modern and efficient 12 vdc unit such as the 
Novakool, Tundra or newer Norcolds.  If you have 120 vac unit 
and plan to power it with an inverter it will consume several times 
the amp hours as an efficient 12 vdc fridge.  Concentrate most of 
your attention on the refrigerator.
