The system is locked to 53 Hz and does not resume

Hi, I have followed all your guidelines and the Firmware version 476 is at the latest revision but the Quattro still holds our the ac coupled Fronius even when the BYD battery is below 54V

I suspect that the BYD batteries BMS is telling the inverter that it does not want any more charging at this time and thus the inverter is telling the solar inverter to reduce or turn off output, it does this by raising the Hz

these settings are done in the Assistant thats been setup in the multiplus when the system was installed. or something is wrong with the setup
