I’m running an IoTaWatt here in Sydney, Australia and after completing our three phase upgrade and Solaredge install (2 inverters, I think A and C phases) I’m struggling to understand what has happened to the branch circuit monitoring. I have reasonably expected numbers on my three 100A mains CTs, but since derived three phase all the branch circuits appear to just report noise? There are at least 500-1000W loads on the GPO circuits and I have a pretty good idea of the layout but I have no feedback at all to start figuring out which branch is which when everything is reading zero?
Apologies for the screenshot spam incoming.
Rebuilt board, an absolute mess but apparently these are “gold class” electricians. It’s a travesty.
CBs and bus bars.
Note: In this image the VT is connected to the bottom most protected power circuit labeled “4”.
Single phase historic data
Now - Three phase derived
What am I expecting? Since the majority of the loads were rewired onto phase A (All GPOs and lights in case of AC coupled battery) I should have at least half of my branch CT’s reading correctly without phase discovery for the other CBs.
I feel like I’ve missed something very obvious but I’m struggling to see what I’ve done wrong.
