I somewhat confused if the abobe system will benefit from enabling DVCC?
Will DVCC coordinate/prioritise charging form MPPT’s and Shore power?
Will it limit input from alternator and prioritise solar power when engine is running?
Will it coordinate that the three sources of charging (2xMPPT and Multi) will be charging using same algorithm?
Because your batteries do not communicate you will not get the charge coordination features of DVCC.
What you can do (which I recommend) is enable DVCC and then enable SVS and SCS, share voltage sense and share current sense and choose the BMV-712 as the source so that your Victron charging devices see the actual battery voltage and current for optimum performance. If you wish to set up priority towards solar then set your absorption and float voltages slightly higher on your MPPTs, maybe only 0.05V higher.
To limit your alternator output you need to have either
an external controller such as Arco Zeus, Wakespeed WS500 or MG AFC300.
Or
A DC to DC charger.
What you will find with many alternators is they are not suitable for charging lithium because they have a fixed output voltage of say 14.5V so they will keep charging a lithium battery when it is full which can damage it or result in the BMS disconnecting. If your argofet joins the starter and house batteries consider charging the starter from the alternator, remove the Argofet and fit an Orion XS DC to DC charger to charge the lithium bank from the starter battery.
