Does my VE bus BMS v2 and Cerbo GX automatically control allow to discharge of my MPPT load?

I have VE.Bus.BMSv2 connected with Cerbo GX and MPPT connected with VE direct cable to the cerbo. Via VDCC the MPPT will automatically stop charging when BMS decides so.

But I have a question about the Load port on my MPPT 75/15. Would the BMS also disable automatically allow to discharge from that Load port on my MPPT?

I am asking because I want to directly add DC loads to my MPPT charger, but want to make sure BMS shut it off when it shut off all other dc loads like connected to battery protect.

No, that load output can't be controlled by the GX device/BMS.

You need to install something to disconnect the loads controlled by the BMS "load disconnect" signal. e.g. a small BatterieProtect 65A or the cyrix-li-load.
