AC200Max net power output

Hello,

what is the net power output via AC. Batterie should have 2000mAh.
If I run e.g. a dryer to discharge from 100% to 0%, looks that I’m landing on at net output AC of only 1,5kW.
25% are really high loss or is the a mistake in the thinking?

Edit: Charging 0-100% is 2,2kWh (AC meter ) to charger as expected with 10% conversion loss…
