In a 3 fase Multiplus 2 system with a MPPT battery charger and a Cerbo all connected to a BYD LVL15.4 KW battery: where does the Cerbo get the Voltage measurement from? (DVCC and ESS are used in the standard BYD configuration).
I think the Cerbo has access to the DC voltage from the 3 Multiplusses, from the MPPT charger, from the battery and possibly from its own power supply connected to the battery.
The issue seems important to me as I seem unable to charge the battery to 100% (I suppose because the tail current does not drop enough or the charge voltage remains to low.
