Quite a setup! I’m interested in understanding this better and figuring out how to use IoTaWatt to get the most insight into how it’s working. That said, I have a few questions about the equipment and line drawing, and a couple of comments on IoTaWatt monitoring vs PVoutput vs influxBD.
First the comments:
IoTaWatt records net power and energy at five second intervals. PVoutput does the same at five minute intervals. So looking at the IoTaWatt import/export graph with five-second net would look much different than the same plot with five-minute net. You can open a second graph window and zoom out to five minutes intervals and see just how most of the spikes will be greatly reduced or even eliminated.
That tees up PVoutput, which can digest the five-second data and feed it to grafana or other visualizations.
If the five minute nets serve a useful purpose (and I think they do), then as a donator, you could upload up to six additional data sets to develop a more comprehensive picture.
You don’t need to wait after making changes to the PVoutput driver to see results. You can check the box to re-upload a few days history.
Questions on the line drawing:
I’m assuming your main CT is on the fat blue line between the Grid and the point where the “PV on AC INPUT” comes in.
Do you have a CT on the PV on the yellow PV on AC INPUT line and what is it named?
Do you have a CT on the fat blue line coming out of the top of big inverter/charger and what is it called?
Are there any CTs on the orange Critical Loads line? I’d like to see one between the inverter and the big inverter/charger, and another on either of the other two parts of the “T”.
Where is the diverter in all this? If it’s just part of the loads, that’s fine. If it’s somewhere else, where?
Does the inverter/charger supply the critical loads during a power failure?
