Inverter 12 VDC / 220 VAC I need to calculate the performance

I would like to know how it is calculated. It is sized to have a maximum output power of 463 W and 2.1 A. The issue is that I don't know how to relate the alternating output to the 12 VDC continuous input. If I remember correctly, with a 100 W lamp, the consumption of the adjustable power supply (replacing the 12 V battery) was 1.2 A.

You can calculate it with the power delivered divided by the power consumed multiplied by 100. You would have to measure the voltage and alternating current that it delivers at the output and the voltage and current it consumes from the battery. Comment on performance result.

That is, directly the alternating output (Vrms * Irms) over the continuous?

The equipment consumes power and delivers power.
It is:
Power delivered / power consumption x 100.
Vac x Iac / Vdc x Idc.
What you consume is always greater than what you deliver.
