AC to DC Conversion Efficiency for Victron Inverter/Chargers

This document describes inverter (DC->AC) efficiency vs power for the Multiplus: https://www.victronenergy.com/upload/documents/Output-rating-operating-temperature-and-efficiency.pdf

As I'm designing my system, it would also be useful to know efficiency for (DC->AC) so I can size the equipment that will provide AC to the Multplus. I know I could assume the same values/curve as DC->AC, but I also recognize they could be quite different. Does anyone have any resources on this subject?

As far as I know the same hardware that convert DC to AC is used to convert AC to DC.
So I would say the efficiency should be nearly the same.
