I need advise with buying the right CT’s etc…
Based on my main panel, how many CTs would I need to purchase to measure whole home consumption as well as solar production? thank you.

Worst case/naive way is a CT for each breaker, around 40, assuming I counted right. Likely won’t fit.
The smallest number is 3 CTs assuming the panel is fed by 2 wires that you can access and there is only one PV system. You would use 2 large CTs for the panel feed and 1 for the PV.
The correct number is probably determined by how many other circuits or groups of circuits you want to monitor.
I forgot, after reading this site, the best answer always leads to: CT Basics — IoTaWatt 02_03_20 documentation
