I understand that my house is running on battery (“Verbrauchte Batterieenergie”) from 0:00 to 6:00 around.
From 7:00 to 8:00 I don’t understand that there is some energy coming from the Panels (“Verbrauchte Solarenergie”) and some energy is coming from the Battery (“Verbrauchte Batterieendergie”).
But what the heck is “PV Batterie Entladeenergie” telling me?
When interpreting the summary at the bottom of the tooltip I would assume that this is the energy delivered to the grid (as the numbers matching). However, why is the bar called “PV Batterie Entladeenergie” and not “Einspeise Energie”?
You might want to show your energy dashboard configuration. The way it looks now is that your home was exporting to the grid while discharging battery and producing solar. In that case it is not clear if what is exported is sun or battery, the graph chose to show it as battery.
I do not know if the energy supply of your home has multiple phases: it might be that solar was producing at a phase that did not need that much power, while the home drew power from the other phases, delivered by the battery. But as said, the energy dashboard cannot tell which energy was exported and which used.
Either way, your battery was discharging more than the house needed at the time, so that seems a waste, unless you get good money for it from the energy company.
The export to grid entity, is that a calculated one or does it come straight from the energy meter?
Sensors from the collector are helpers which use a integral function to calculate kWh from actual kW read from the inverter. I guess that is the reason for the wrong device-class mentioned by the configuration.
These sensors are helpers which use a integral function to calculate kWh from actual kW read from the inverter.
The inverter has 3 phases and actually cleans out all phase differences (no idea why it is actually doing this). So there is no chance that a single phase is consuming and a other phase is delivering energy to the grid.
Also the inverter is not discharging the battery while delivering energy to the grid (as indicated by the visualization).
Any other hints what’s wrong with my configuration?
