How the Backup battery can handle more Watts?

I do have APC Back-UPS ES 8 Outlet 550VA 120V Model # BE550R
It may seem dummy question but I really do want to know how this work, my question is if I do have the backup batter APC with Max 330 Watt but I connect to this a total of 3000Watts is that mean the APC UPS will required more AMPS is that right and if it is up to what this Model will go for the Max AMPS and if this not the way it works can you please tell me how.

first of all, a 550 VA ups will not power a 3000 watt load under any condition or battery. 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.
