BMV Settings on a 24V Lithium System with Solar

I have 2x 200Ah /24V Lithium batteries, a Smart BMV-712 and a 400wpeak solar system connected via the SmartSolar MPPT controller all systems are from Victron.

Could you please confirm the rights BMV settings?

Attached is a pic of my current settings.

The charged voltage should supposed to be 0,3v below absorption voltage.

The absorption voltage on these batteries is 28,4V correct?

I received mid voltage errors as well.

I have 2x 200Ah /24V Lithium batteries,.....,,I received mid voltage errors as well.

These 2 bits of information do not match..

Please confirm if you have 12v batteries wired in series, or 24v batteries wired in parallel..

Sorry I have 2x 200ah /24V Lithium batteries. The batteries are parallel therefore 400Ah and total voltage remains at 24v.

The installation is in a sailing boat, therefore 24v. I have the Victron Venus software running on a Pi as well.
