I made an ESS system with Cerbo GX Quattro ET340 with a PV inverter connected upstream of the Quattro on one channel of the ET340.
The four starts when the grid fails but does not start when the PV inverter stops producing.
I have installed the ESS assistant, disabled the virtual switch and configured CEI-021 as Grid code and LOM type B.
Do I need to configure anything else? Thanks
