You start pulling 250 A on a regular basis and your going to have some equipment, as in battery, alternator & wiring doing some complaining, and failures! System is just not designed to more that kind of amps on regular basis.

Might want to check that math again. 3000 watt DC to AC innverter will put out 25 peak amps and 16 continous. Depending on the inverter it will draw about 5% more amphs from the source but thats about it. At a reasonable draw a 800 amp battery will run one long enough for a hurricane to pass and you can get your generator hooked up. I've kind of done this, several times over the last 25 years.

Sorry, your wrong. Might want to check that math again. Look at the post below yours.
3000W output divided by 12V = 250A input

It's 3000 divided by 120 volts, not 12 volts. That is why it's called a inverter. It turns direct current into the more efficent alternating current. If it were drawing 250 amps of direct current out of a battery, it would explode fairly quickly.
