I've build a 3 Phase System with 3xMultiplus II, battery and a cerboGX -> all running fine:
Now I want to add my Grid Tie Inverter to the VRM (as PV Inverter). I build my own AC energy Meter with an ESP32 (Arduino) a long time ago, so the data is available on the LAN network (MQTT).
1. Is there a way to send this data to a mobus register on the CerboGx? (Could not find it, but maybe I missed it)
2. Can I emulate a pv inverter by implementing a modbus tcp client on my ESP32? Are there some examples anywhere how to do this?
3. Any other Idea how to do this?
Thanks for any hint :)
