Older inverter/chargers, especially Freedom modified sine wave units, have a notoriously bad power factor. To compensate for this, Freedom (now Xantrex) issued a technical note several years ago saying, in essence, regardless of the calculation, don't attempt to power the charging function of a Freedom 2.0 kW or larger with less than an 8 kW genset.

That being said, you can limit the amount of incoming AC power that is used for charging but you pay a price in longer run times.

Hope this helps.
