Electrical: DC AC Conversions - Efficiency

Thanks Mrwizard for answering the questions related to differences in generator output and charger input and the practical application in the field...good stuff! The puzzle is coming together.

Question: When the Charger transitions from the fast charging rate to the next stage, let's say for example it goes to 1/2 the fast charging rate, will the Generator sense that load reduction and throttle down also to Eco Mode as long as that output is able to satisfy what the charger is asking for?

thanks Tim
