Power assist

And if I understand it, the input current will be used to the maximum first and the rest will come from the battery, right?

Yes.
Just be aware that there is a minimum level for power assist.

Over 6a ac input, the inverter will assist with a minimum of 1.6a.

The ac load has to fall below of 4.4a before the power assist will cut out.
