I finish to update my BYD battery to latest firmware (after waiting for the special USB to CAN cable from them) so I finally plugged everything and was hopping to have it all to work.
We did the installation a few weeks ago with my PV installer, we did set up to date color control and inverter, and he setted up the victron inverter and color control configuration for them to be ready to discuss with BYD. As the battery was on a too old firmware, I had to wait to update them to latest firmware which is now done (BMU and BMS).
So I finally turned everything on. BYD is recognized by the color control, mppt is charging them, but when I turned on the inverter, it constantly disconnect and reconnect from CCGX.
here is a small video showing what's happening.

Any idea what could be happening? How I could fix it?
Also, the inverter has a (quite) loud electrical noise. Is that normal?
Thanks,
Thomas.
