Hello! Who can help me with a Modbus TCP connection to the CCGX? Under which unit ID can the address 2901 be read or written?
Did you try Unit ID 100?
Hello! I have to pick up the topic again, with UNIT-ID 100 I can not read the register 2901. Who can help me? I would like to specify the minimum discharge value SOC via Modbus. Thank you!
You need to download the Modbus TCP Registry spreadsheet. In can be found here:

It also has a Unit ID to Device ID sheet.

Hello! The Modbus function to write register 2901 works, thanks for the support. I have another question: where can you read what the current utilization of the solarcharger is? Is the Maximlae Powerpoint visible in a Modbus register? I want to find out how much power reserve my solar panel still has to control a heating cartridge. Best regards, Roland
