This is a simplification of an earlier question:
In an ESS system, if the Fronius and Cerbo GX are ethernet connected, is all management of the Fronius PV output via the ethernet connection please (both when the Grid is active and in the event of a power failure with micro-grid)? In my system, frequency shifting will not work so I am hoping that when the Fronius is ethernet connected this will avoid it's use even in a micro-grid.
