up to a 9" combo will run off a 300w inverter.  a 13" combo will need a
500w inverter.  When you price inverters be sure to check continus output
not peak.  Inverters are often listed by their peak output.  The peak
rating is output at 1/2 wave (1/120 second).  your TV will draw it's peak
output for close to 10 seconds depending on model and ambient temp.

If you are going to go the seperate unit method, be sure they are both
running on the same power source.  ie, don't try to run one on an inverter
and one on DC.  Sometimes you will get a rolling picture caused by ground
loops (see a really good electronics- A/V book for a detailed explination).
 It may not happen all the time, but sooner or later it will happen.

In T.U.R.D. we run seperate VCP and Monitor off a 600w inverter for the
kids.  the efficiency of the inverter is only 90% so we don't get much time
off batteries, and often leave the whole set-up at home.

Hope this helps..
