Why is Multiplus in absorbtion and smartsolar still in bulk?

I have a 5000/70 multi, 4 kW Fronius on ac1 out, a 250/70 smartsolar on dc bus and 2xEms48100 li-ion batteries.

If the Smartsolar and MultiPlus are not in an ESS system (with a CCGX or VenusFX etc.) then they will operate independantly, running their own algorithms.
In that case you can expect each charger to switch to different charing stages at different times.

In that case the MPPT should be under "External control".
It should say this in the Menu for the SmartSolar in the Device List:

If it says "Bulk" there, then it is working standalone. You probably have a communication problem between the SmartSolar and the CCGX.
How is the SmartSolar connected to the CCGX?
