I'm trying to configure my Multiplus 3000 to allow shore power pass through to my AC loads, without necessarily having the batteries charged by the Multiplus. There are several threads on this question in the Community suggesting that the charge current control assistant and an external switch on an Aux input can be used to provide this functionality, but there are few details. I cannot find any description from Victron, other than the general overview, about how to actually use the charge current control assistant.
