The first diagram that I provided which I believe is the the way your system is configured is the only way you can use a grid-tied inverter of any size.
You just have to tell the SS inverter the AUX port is used as a MicroInverter - sound a bit wierd, but it works. This is how my system works.
You will see the PV exported power on the SS generation graph. This is because the CT will see the power.
