SmartSolar external control by BMS not working? Will not feed-in excess DC-PV?

I have a Batrium BMS canbus connected to Venus GX and 3x Multiplus-2 48v 3000. This have been working fine for 1,5year. The Multiplus-2 follow the CCL from the BMS.

But now i have added a SmartSolar 150/35. Connected it to Venus GX by VE.Direct. It says "External Control" but i does not follow the CCL or CVL as the Multiplus-2 does?

I found a picture here that someone have the "Externa control" label at the SmartSolar in VRM, that i dont have? I only find it in "Remote Console"? Maby it have to be a SmartSolar with VE.bus for this?

DVCC is off and "DC coupled pv feed in" is active.

Charge Voltage is to high? My CVL is 53,4v.

Did you get a solution for this problem??? I have exactly the same issue, MPPT is not reacting to BMS request to stop charging. It keeps pumping the amps to the battery
