How can the DC System consumption be added to the AC consumption in the Installation data View

Hi,


would be great if there is an option to build the sum of DC consumption and AC consumption in the VRM Portal Installation data view. This as soon as "has DC system" is activ and data is received from a DC shunt set to "DC system". Or is that implemented and I just dont know how to activate that?

It might allow for a better interpretation of how much energy was solar harvested and how much energy used.

systemcalc in the GX device does not compute a DC consumption value. Maybe it should and then a total consumption added as well that includes both AC and DC consumption. Without at least the DC consumption value, it would be difficult for VRM to calculate it. Using a value from a DC system DC meter would be simplistic and could miss important consumers, especially if there is no DC system DC meter.

I have this set up in VRM. 'Has DC system' is disabled. Not sure whether it is what you want.

Hi, this seems to be an open topic, I don’t understand how we can see DC load in “W” live, but not get a value for DC energy consumption? How hard can it be? DC load multiplied by time? This is really annoying, because it looks like there is energy disappearing img-1060.pngImage Caption
