Persistent Issue with Quattro Inverter not switching on

I am still experiencing the same persistent problem with my Quattro inverter: whenever I switch it off or perform a remote configuration change, the inverter only comes back on if I remove the VE-Bus cable.

I am unsure if this is an isolated issue, but I have encountered it at a customer site as well. Notably, the issue was present with firmware version 362 and on the old interface before, and after further investigation, I have confirmed that it persists even with the latest Beta firmware.

This is proving to be a significant challenge for me. Have you come across this issue before, or do you have any ideas on how I might resolve it? Any guidance or suggestions would be greatly appreciated.

Thank you very much for your assistance

Is this GX powered by AC or DC?

Have you read this topic?

No but have now, I don’t think that is the solution, this started happening when I upgraded my Quattro 48/10000 to a Quattro 48/15000 - I am running from a single power source Freedom Won 60/40. I have industrial shielde cables.
Could it be that perhaps I have a faulty control board in the inverter, I have tried a different Cerbo as well?
