Having 7kW AC, 5kW battery charging isn't terribly unbalanced. You draw power 24 hours per day and get 5 hours effective sun.
With 12kW of PV, 2.5kW average AC is all that's going to be available to you (off grid).
But incorrect expectations set by vendor data sheet is a problem. Maybe you expected to pull more power for A/C during the day.
Could it be that 7.2 kW limit is due to ambient temperature higher than 25C, and inverter could have done 9 kW if temperature not elevated?
A bigger fan might help. AC coupling (spend more money on additional electronics) should help.
