Greetings everyone,
What change do I need to do to see Bulk/absorption/float status on Vrm instead of Ext. Control that I have constantly now (see attachments)?
The little but of float is because I just connected the MPPT to the Cerbo yesterday.
Thank you
Hi @Michaeltenerife,
In an "externally controlled" system, the built in charge algorithms are disabled. So Bulk, Abs, and float algorithms are no longer used.
This is most often done when a system charge state is being managed by an external lithium battery BMS for example.
There is a little bit more about it in the manual here.
ohh, ok. So if understand it well: because I connected my pylontech battery to the cerbo as well, the battery is controlling automatically the mppt? There is no need for configuration here anymore? From Victron advice for pylontech batterie charging configuration (https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom) the following information was given: 
Even though I introduced these values in the MPPT configuration, this is now overwritten by the battery for it's optimum care. Is that so?
Thank you for confirming.
Thanks for clarifying. It would be useful for the display on the Touch screen to show the charge decision that the BMS decides. The LEDs on the Quattro show Bulk, Absorption, etc even while the screen displays Ext.Control. The Touch screen used to show the charging mode in previous firmware revisions (before last Autumn).
