Hello @Nicolas
Thank you for moving the Thread in the correct forum.
Just to clarify the problem: If our System delivers more than 32000 Watts into the grid the EVCS Dashboard shows 32000 Watt instead of -32000 Watt. So the EVCS think the system gets power from the grid and stops charging in “auto mode”.
I think it is a simple problem with a Modbus register which is to small. Just the communication Cerbo → EVCS.
