Fronius feeding back to the grid. How can we stop it.

We have a fronius symo 6.0.3 at the output on three quattros 8 kVA. There's ESS, PV inverter and PV size with a ratio of 1 to 1 set on the master inverter and on the two slaves. There is a victron gateway grid meter. grid set point is at 50W. feeding limit is set to yes. frequenc shifting parameters have been set. There is also a victron MPPT but it does not export excess PV to the grid, only the fronius.

The Cerbo GX and the fronius are connected to the same wifi connection.

Is there a way we can prevent the fronius inverter from exporting PV to the grid?

Fronius, Cerbo and Victron inverters are on the latest firmware

These are the zero feedin settings on the GX. The carlo gavazzi meter (Victron meter) should be able to prevent the fronius from exporting. Fronius is on the output of the victron system, DO WE NEED A FRONIUS SMART METER HERE.

Have you tried disabling AC coupled PV and same for DC if you don't want to feed in?
