Looking to get two IoTaWatt units for monitoring a bunch of circuits ranging from 10A-40A / 240V (Aussie install), with two 3-phase (Telsa wall charger 3x16A and AC unit 3x40A) feeds. One IoTaWatt will be in a small sub-panel, the other IoTaWatt in the main panel. No measure of mains as I get that data from PowerWall.
- How close can the CTs physically be together? Is there cross talk possibility?
- Looking at using exclusively the 50A solid core 9mm ones for accuracy and size, in some cases the wire would be smaller than 9mm hole, is this ok? What’s the tolerance?
- Any other drawbacks of using all 50A 9mm solid core ones? They could be fine with 3-phase feeds as they are <50A per phase?
