you might add that a lot of 12vDC is required to do much with an inverter...

just to put this conversation in context...
1,000 watts (about what a small microwave would consume) of AC @ 120 V uses about 8.3 amps of current... not much
BUT using an inverter (DC to AC)
to obtain that you have to pull about 80 amps of DC current at 12.6 Volts DC
SO
a fully charged 12 V battery will discharge to an unusable point in just a few hours at that rate of discharge...
Conclusion... you have to add up the watts you think you need to sustain the ac appliances you wish to use and come up with the size of inverter and enough battery power to sustain that usage. The alternative is to purchase an inverter/generator with enough watts and purchase the fuel, either gasoline or propane to power this genset for as long as necessary.
