Below data from my ECU-C from APSystems which comes with CT transformers for consumption monitoring.
Some allow you to download spreadsheets for you to work with.

hey davidcheok that charting looks fabulous. Not to derail the thread even more, but I guess it is my thread... how do you like the APSystems microinverters? My local supplier doesn't sell them but I was really curious about the quad input models (love the idea of connecting 4 panels to one microinverter)

I like that because they are cheaper than Enphase per unit AND Its cheaper overall than Enphase because of the 2 to 1 and 4 to 1 design. Support wise from my side in AsiaPac is good from installer to manufacturer. They wont deal with customers direct.
