Monitoring SMA PV Inverters

I would like to integrate the Sunny Boy 3000TL with the Victron Multi Grid as described in the manual. But i have run through the troubleshooting steps without success. I cannot see any device on color control (CC) interface as described in the manual. even when i am setting manually the IP address of the device.

I am able to ping the inverter from within the CC, so i have verify that this communication is ok. Moreover i am able to read SMA's parameters from my SCADA which means that the modbus TCP capability of SMA is enabled. Sunny Boy listen on modbus ID-3 but i cannot verify that this is the default for the CC.

Thanks in advance

Try setting the modbus ID to 126.

Unfortunately, it is not clear to me how to set the ID on the ModBus server (Color Control) actually that was the core of my question from the beggining. In regard to the modbus ID as i mentioned i am able to communicate with the SB at ID 3.

Not sure what you mean with the modbus ID 126, please clarify.

Hi @avassil

As Izak mentioned, the SMA is supposed to be on modbus ID 126, otherwise the GX device doesn't see it.

Thanks for your clarification. I didn't know that is possible to assign SMA devices to individual Unit IDs. I am putting here the product manual for future reference.

By the way, is it possible to change the default unit ID (126) into the Color Controller?
