Multiplus VE Bus voltage step change behavior

When observing the slow decline of battery overnight with charger off one sees a step change in voltage 'VE BUS " which is not seen on the BMV 702 monitor . Its not because quantising is large as there are indeed 0.01V steps in the data. See comparison. ( Multiplus 1 - 5kVA vs BMV 702 ) . What is the cause of this?

I would suspect that its just different sensing points. one being inside the multiplus and the other at the BMV shunt

nothing to worry about
