Do you have a Sepols BMS? If yes - check https://diysolarforum.com/threads/seplos-can-bus-rs485-48v-200a-8s-16s-bms.20051/post-790692. If not - open a separate thread for your issues and I'll try to help.

Well, open a thread, provide your current setup and configuration and people here will likely help. I'll also try to spot a problem in your setup. But this thread and your problem have close to nothing in common.
