Victron multiplus efficiency? Over 700watt of selfconsumption while charging??

I have 2 Pylontech US3000C batteries connected to my MultiPlus-II GX.


While the batteries are charging the dashboard tells me:


At the upper left, under "Grid": 4300 watt

At the bottom, "Charging": 3550 watt

At the top right, "Critical loads": 165 watt (While I don't even have anything connected to the multiplus backup ports?)


So, why is it using 4300 watt to charge at 3550 watt?

That's a huge difference of 750 watts.


Efficiency can't be this bad, right? So I wonder what's happening here...

Conversion losses are 10-20%

In this case, removing loads (1:1) you have a net 15% loss.

Feel the cables, they are warm right? Meet power loss.
