Fronius Primo connected to the AC out of Multiplus ll

Please assist, I have connected a Fronius Primo 5KW to the output of a Multiplus ll (5KW). Multi has latest firmware. After setting up the PV assistant the Multi is only turning the Primo on to top up the battery bank. I need the Fronius to be online to assist with AC load while the MPPt's take care of the batteries. The Multi has no AC in.

@André Vorster

How is it connected to the system for communication?

Is the fronius itself updated and programmed?

All on the same wifi network and the Fronius is updated to version 35020.
