Victron and PLC

Dear community,

I have a PV with 3x Victron MultiPlus-II 48/3000, 2x Victron MPPTs, PylonTech battery and Cerbo GX.

I would like to programm a PLC to manage loads based on current yield from PV, battery SoC and load of the inverters.

Is there a way to output information in the real time about battery SoC, PV yield, load, etc. from the Victron system into the PLC?

Thank you for your advice

..enable Modbus and/or MQTT on the Cerbo. This way the PLC can fetch the data from the Cerbo (via modbus) or subscribe (mqtt) to the mqtt-broker on the Cerbo.
