I have an Orion 12-12-30 (isolated) between a smart alternator and lithium batteries. The unit is low hours.
I've had two overcharging warnings on the GX today, over 14.8v. The Orion, MPPT and Multiplus are all set at 14.4v absorbsion and 13.3 float, as per the battery manufacturer's specs, and a 0.1v rebulk.
Any ideas?

That looks like an equalisation has occurred where you get a higher voltage for 1 hour once per month to equilalise lead acid batteries. This is not required for lithium so turn it off and set the equalisation voltage to the same as absorption voltage so nothing happens if it gets accidentally turned on.
Have just had confirmation that Victron are going to refund the unit.
