Howto disable BMS control, while keeping CAN-bms connected

Hi everyone,

Below it shows that BMS control is enabled automatically when a BMS is present:



Is there a way to disable BMS control, so that the MPPT manages charging the battery from its own charge settings, while also having the measurement info (SOC for example) from the BMS displayed via CAN?

Hi @ryanb

This is not possible, it's a safety feature.

I don't understand the safety aspect?

The only reason I've plugged in my BMSs to the Cerbo is for monitoring and data logging.

Yes. it should be possible to use a CAN BMS in a way where it doesn't control the system, but simply for monitoring. While I understand that most people don't need to use it this way, some do and may well be clever enough to understand the consequences of doing so.
