SMA on AC-Out disappeared

Hello!

I have a 3 phase ESS system with a ColorControlGX, 3x Multiplus 2, Fronius on AC-IN and a SMA Tripower Inverter on AC-OUT.

Everything was working fine but a few days ago, the SMA on AC-OUT disappered from the CCGX and VRM portal. I haven't changed anything.

The device entry is still shown in the "inverters" menu but not in the "detected ip addresses" menu of the CCGX.

I checked the following:

TCP Server is enabled
UDP Server is enabled
modbus ID of the SMA is 126 (3+123)
ping is successful
telnet to port 502 is successful
inverter data is shown in sunny explorer and in a logging application with UDP communication
restarted the whole system
updated to the most recent CCGX FW
manually added the ip in the CCGX
did several inverter scans in the CCGX
changed all relevant settings in the inverter and ESS menu

Is there anything else I could try?

Thank you!

Best regards

Thomas

The problem is solved.

I disabled and re-enabled the UDP and TCP Server of the SMA inverter.

Hello, I have the same problem, my SMA tripower dissapears and reapears i also have Fronius inverters connected two of them and they work ok but the SMA is on and off intermitently.

I tried enabling and disable UDP TCP but nothing ... sometimes i just restarted the SMA inverter and it reapeared.

Any ideas ?
