I have the same problem, and I've checked the communication, and it's working fine. The BMS's SOC is displayed on the inverter screen just like it is on the BMS screen, but the inverter doesn't use it to manage the charge. I assume it has an internal SOC. My problem is that in winter, I need to ensure the charge is always at 100% because there can be many days without sun and with dense fog, and I end up depleting the battery and the inverter disconnecting (I'm off-grid). With the battery below 25% (according to the BMS), when the sun comes out, the inverter charges it at a mere 500W. But if I change the battery configuration to voltage, it charges at 7 kWh. That's why for the last two years, I've always used voltage in winter, and it adjusts the voltages according to the BMS's charge. I was thinking of writing to Deye to complain and explain these tests, but I think they'll just tell me to manage it with their new AI, and I'm not interested in that. I heard from an acquaintance who left the management to this new AI, and that it improved, but this acquaintance is connected to the grid and I don't think it's optimized, since by default these inverters always prefer to inject energy (Could it be that they have an agreement with the electric companies?)
