A bigger battery will increase the run time during an outage for a proper load. The transistors in the power inverter simply won't pass the required current at 3000 watts, and the output voltage will sag. An internal protect circuit will probably shut the ups down to prevent damage. first of all, a 550 VA ups will not power a 3000 watt load under any condition or battery.
