About the System load and grid load, it depends on the way your house load is connected. In my case, everything is on the backup line, so system load is "residual". To get correct reading though, you need the DSU666 smart meter correcly installed and connected to the inverter, otherwise the inverter can't get precise statistics of the current that goes to the grid and the current that goes to the house.
About the difference between Active and Apparent power, if you need an explanation of the difference between the two and how they are linked and you can check google for that. As general rule of thumb, keeping Apparent power as much close as possible to Active power is a good idea, and the inverter does some magic to adjust the power factor to do that.

I see some weird (zero values) for registers where I would expect to see something. Let me explain with an example. This parsing is the result when my PV was producing, battery is charging, there is a load in the house, and no import/export from/to grid.
I have some trouble with understanding the data outputs for grid, inverter, output and battery. Not sure what these current and volt values exactly mean... As I don't often see them matching the results in the "power summary". Not sure if you know what they exactly mean (active power vs apparent power) and if those values are useful for something?
If you look at the
Power summary, it seems that:system totalis my load in my housegrid totalalways seems 0 (also in other cases when there is import/export from/to the grid)inverter poweris always 0backup loadis always 0 (normal as not connected, but still weird it shows 64VA)unknown parameteris 0 (but this seems to be the import/export from grid as it displays values when grid is being used)smart meter poweris always 0Do you see similar results on your inverter? Or could it be that some registers are sending other values depending on the firmware/type of inverter? If you see similar results, maybe we can rename some outputs?
Example when no more PV production, battery was already discharged and all load is taken from the grid:
Here you can see that the
unknown parametershows the import from grid value. I would also expect that thesmart meter powerwould show the same value as theunknown parameteras everything is taken from the grid in this case. (And I do have a smart meter connected 😉)
