New SUSTAIN mode and need to keep MPPT voltage differentials

Great to now have SUSTAIN mode for Multis in systems including solar and/or wind generation, to give solar/wind priority over shorepower. Very simple to set up with exceptionally clear instructions...congratulations to Victron on implementing this much-requested feature.

Previous to this, one work-around to achieving solar priority was to set Absorb & Float voltages in the MPPT a little higher than those set in the Multi. With SUSTAIN mode implemented, is there still any benefit to keeping these threshold differences ?

@Aquabelle

Ideally now, you would be able to set everything the same and as recommended by the battery manufacturer.

If it doesn't work well, then feedback would be appreciated. There is always room for improvement.

You could make that voltage value something changed dynamically via MQTT! That would be cool.
