To make the answer short. YES there is
Many, many of us have done it.
Longer answer one, (All outlets you wish to power on same circuit breaker)
Get an "in-line" inverter and remove the wire from the breaker (Also remove the partner wires (White/Bare) from their circuit buses)
Route a new wire of the proper size to the inverter, route a new wire from the inverter to a junction box and hook it to the original wire from the breaker. Job done.
Method two (Multiple breakers)
Get a "Sub panel" (This is a breaker box without provisions for a main breaker)
Remove all the breakers you wish to have Inverter powered, Get a bigger "In-Line" True sine wave inverter (NOTE I forgot True Sine Wave in above paragraphs) Install the proper size breaker for the inverter in one of the vacant slots and route the proper size wire from it to the inverter, Likewise back to the sub panel, Install the original breakers, wires and all, into the sub panel,
And that folks, is all there is to it.. Progressive Dynamics makes a very nice breaker panel which could be used as a sub panel, or Square D (I have a PDI main panel and a Square D sub panel here)
Inverter mounting: Inverter should be mounted as close to the batteries as possible but NOT IN THE SAME AIR SPACE, you do not want it breathing battery vapors.
