I have added an EV charging station to my PV system. Communication with the Cerbo GX takes place via a WiFi network. The situation is now as follows:
The EV Charging Station "sees" the Cerbo GX and receives all system data. Everything is shown correctly on the display. However, the Cerbo GX does not see the charging station. It is neither displayed in the device list nor in the VRM.
If I let the Cerbo (192.168.101.64, FW V2.763~r12) search for Modbus TCP devices, an error is generated:
ERROR "Error processing function code 3, unit id 1, start address 5664, quantity 1, src 192.168.101.64: Modbus address 5664 is not registered"
One thing I should mention is that my system is a pre-configured system (salidomo by innov.energy), which uses FIAMM salt batteries. That's also the reason I didn't upgrade the Cerbo GX Firmware yet, because I don't know what kind of modification (if any) they did for the FIAMM batteries.
What could be the problem? Thanks for any help.
