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
We would probably need more info. Like are your batteries ok? Has your Quattro been configured to charge them from grid correctly (in your case from the pv).
Is the PV on AC1 or AC2 input? If your disconnect all your ac inputs and outputs does the Quattro startup in stand alone inverter mode?
It is connected as indicated in the Victron documents. It is read regularly by the Cerbo GX. Access the VRM portal with giorgio.cavalera@outlook.it Alexandra2021
