Great set of videos! I’ve got a similar problem and wanted to ask about how to build the AC side of the circuit. I have the power data scraped from the inverters modbus port so just need to simulate the signal for the harvi.

I’ve found some ac 240v to 5v transformers so was planning to put that into a small box with an esp32. Then use the esp to generate the signals to control the simulated ct clamp.

I just can’t work out what components you’ve used or how the ac part functions. How does it deal with the ac? A lot of the components I’ve found for variable resistance only allow dc
