Consumption in VRM always only from solar, never from battery

I have ESS system with 3x MultiPlus 2 5000 in 3phase configuration, RS450/200 MPPT, self-build battery with Batrium BMS utilizing DVCC. Currently, the grid is not connected as I have mostly very little critical loads (less than 50W) and grid connection would have a setpoint of 50W and therefore consume more from grid than I have as loads most of the time. But there are times during the day and in the evening when I consume power and then mostly from batteries.

VRM unfortunately only shows, that all power from solar is immediately consumed:

So for consumption overview I would have excepted something similar as what I see in AC consumption. Why is that different? If that is fixable, how can I fix that?

Many thanks in advance!

Is the Batrium shunt set as the default battery monitor in your GX?

Yes, Batrium Shunt is configured as the default battery monitor in Cerbo.

I can only see your post, but not the link (was in my notification email), and the answer a bit hard to find:

Hi,


Can you please turn off option "Has DC System" and then check if it is working, had same problem after turning it on.

Regards,


Hank
