Reverse power to Grid in AC Coupled System

In AC Coupled PV systems using Fronius and Victron inverters, I have observed that at times when Grid is available and solar yield is higher than is load demand, the excess is shown to be going back to the grid. How can this be prevented as setting for Quattro inverters and Fronius is no grid feed in.

This is quite a serious issue as Grid feed in is not permitted in my country.

Deberías mirar en la configuración de los inversores que el vertido a la red estuviera desactivado. O si tienes un sistema ESS con el CCGX, mirarlo ahí. Si tienes el Fronius conectado en la entrada del Quattro y este no puede verter a la red, seguramente sea configuración del Fronius.
