All the solar is going into the house. There are no exports (Arrow C), the inverter is not limited. Simple arithmetic shows that as long as the house is consuming 1.5kW or more the system can never export more than 3.5kW (5kW-1.5kW = 3.5kW), so the export limiter will do nothing with a house consumption more than 1.5kW.
If, at any moment in time your power flow to the grid goes close to 3.5kW, the inverter's export limiter throttles the solar back, to ensure exports to the grid never go over 3.5kW. Remember the solar electricity will always be used by your house first, with any surplus solar sent to the grid.
And they should give you your deposit back if you are not happy. But great question about the export limiter. An export limiter of, for example, 3.5kW on a 5kW inverter will not limit the output of the inverter to 3.5kW. It will (if properly configured) limit exports to the grid to 3.5kW.
So for all practical purposes the 5kW inverter size limit applies to most single phase households. But even with a 5kW 'system size limit' you may well be able to install up to 10kW of panels! How? By oversizing your solar panel array relative to your inverter as described here.

An export limit, as applied to inverters, restricts the amount of excess solar energy that can be sent back to the grid. This is often implemented to comply with grid interconnection

Solar export limiters set up a stipulated energy export rate. If the solar panel can generate more energy and your house, consume less than that, the limiter exports the excess power

PEL is applied to the system using the grid profile. Within the Enphase Installer App, you will see grid profiles are available with diferent power export limits; for example, zero export, and 10 kW PEL.
