ESS Fronius PV setup on AC input Victron training

Hi I followed the training video but looking at the ESS PV inverters I do have a Fronius inverter on the AC input so selected no but the training seems to imply that you select yes regardless whether its on the AC input or output, can any one clarify what the setting should be?

Thanks Rod so do you select yes even if the PV inverter is on the AC input of the inverter

Simple setup FRONIUS on AC input side, Pylontech 3000c x3 with BMS into Cerbo, Victron Energy meter, and multi II 5000 with firmware 501 ESS optimised with battery life (Active SOC limit 70% seems very high for these batteries but as the have only been connected for 5 days with very little load only simulation loads on the AC out and AC in to check grid feed in which does not seems to work very fast eg if I turn on the AC in load it does try to zero out but when removed feeds back into the grid even max feeding is set to zero, Any one got any ideas

ESS settings as shown in the images from the ESS manual I assume the Fronius is on the output of the inverter as I don't get the same settings as shown below can anyone confirm and if so what are the settings if on the AC input side of the inverter
