By inverter, I assume you mean that there is a device that powers up a few 120V outlets in your rig. If you can do without those outlets for a while, just disconnect the inverter from the battery until you can get to where you'd feel comfortable with the service available.
If you mean your converter, the device that converts 120Vac to 13Vdc to charge your house batteries, and powers the 12V lights in the house...along with many other items, you might try an extension cord to a different outlet supplied by a different breaker. Just to check that the breaker isn't at fault. Also check the converters voltage at the batteries. If there is a shorted battery cell, that could cause an over current condition causing a circuit breaker to blow.
