How i find the power of a power inverter?

I have a power inverter with 500V DC input connected to a 220V AC line. How i find the power of the inverter?
Say that the output current is X amps.

    None of those specs speak to the maximum power available. You’ll need to find other information on it. You’d need either a power or a current rating.

    If the rated current is I amps, then the power is V*I*PF, where PF is the power factor and it is equal to cos(theta) where theta is the phase angle between the voltage and current. Note that the inverter is rated in volt amps which is different than watts.
