I’m trying to wrap my head around this, I really am
Basically if you go back and look at your system before the solar was connected you “net” consumption was exactly what you measured just like it appears now with solar before there is any production from the panels.
Yes, but it appears as so also after production starts, e.g. in this part of the graph:
Red line is showing “Net” and before green line (Solar) starts rising, it is also showing the consumption. This is clear. But then Solar increases from 200W to 800W, I’m assuming what my appliances are consuming stays still around 600 W, also Net stays still around 600W on this graph. How I understand “Net”, it should decrease at this point, no?
Your clip-on sensor (CT) will sense the direction of current flow and if you can download it’s output from it’s monitoring site you will see this.
This I don’t quite understand. What I see on the screen of the EnviR (and what I can check from the logs) is matching to what is reported to PVOutput. Or that is at least what I assume. Maybe I need to recheck.
So do you think PVOutput is showing data in some other way that EnviR actually measures (while there is solar production)? I’m using the upload service running on RPi and couldn’t find any particular settings. There is possibility to do some pre-upload calculation but I should have the solar power available on one of the channels of the EnviR and I haven’t.
If we say that I have a constant consumption of 600W while solar outupt increases from 0 to 2000 in steps of 100. In my setup it would seem that red line stays at 600W until solar output hits 1200 and then after that starts to increase to 1400W (when output is at 2000W). But does this apply to every situation so that I could always say that my consumption is what the red line is showing until the point that Solar output is over double the consumption. After this I would need to subtract red line from the green line to see what my consumption is…
edit: can the logic be this: EnviR always shows the “dominant” value whether it is consumption or export. While solar output is 0-2x consumption the “dominant” (bigger) value. When solar output is > 2x consumption then export becomes bigger than consumption and will get reported.
