Dc power flow reversal on Cerbo interface when inverter on

[Sandbags]

Hi, I have noticed DC power on cerbo screen indicates power flowing into the battery when the inverter is on.
Inverter is a Victron multi plus 2.
I have checked Victron smart shunt is wired correctly.
I have multi plus earthed to negative bus bar and bus bar earthed to chassis. Removing earths does not alter anything on screen.
I am out of ideas as to the cause.

Dc power or battery power?
Can you post a screenshot?

It’s labelled DC power, I presume what it’s feeding into is the battery (not labelled).

I would switch off the tile (if you enabled has dc system) since you don’t actually have DC loads.
Ideally you would have a shunt to measure the load if you did. But in your system the shunt is for SOC of your battery?

Thanks, I will turn off the DC loads tile. Have you any idea why this shows on the interface in this way?
Are my12v/24v loads not classed as DC loads in this case?

I think I understand, the shunt is measuring SOC , so is the load estimated through other means.

Yes basically if it sees a discharge but it is not measured on the ac side the missing consumption is assumed as the dc load. But really is is self consumption and other conversion losses.

Thank you for your help👍
