[T2] Coolers, Fridges, and Electricity

[Mike Benthin]

1800 watts divided by 12v = 150 amps draw out of the battery- you look 
up the wiring diameter for that!  Even with engine running, a 55amp 
alternator will not be charging anything under that load.  A 2 battery 
set of 6v 100 AH in series will allow 200 amp hours theoretical, 
practically (for battery life), 100 amp hr at 50% allowed drawdown- that 
is one hr at 100 amps, or enough to run your microwave about 1/2 hr!

  is a very good comment! ,,, if you want 1500 watts out.. you need to be
  able to supply 1800 ish watts to the unit ! .. and 1800 watts DC from a
  12 volt battery needs VERY LARGE wire... and enough battery to supply
  that power.. or 2 batteries.. or 3...
