I just installed a 15000 quattro + 2 parallel units of 13.8 BYD Box. I enabled battery monitor and I used 540AH Battery capacity. 108A as charging current (will the charging current be automatically determined by the BMS or the input battery charging current from the VE config plays a significant effect in the charging current?) float voltage is 55V, absorption voltage 55.2V. No assistant installed. No MPPT. No ESS settings.
