I just got my Iotawatt hooked up. It came with 2 100 amp CTs which I used for my 60 amp EV charger circuits. For the SEM monitor, I'd look into purchasing a 100amp CT, and see what kind of signal it puts out when you're pulling more than 50 amps. Note that depending on the CT sensor you get, you may have to splice in a connector. Looks like they use standard 3.5mm audio jacks.
