Okay so forgive my ignorance but I did some searches and can’t quite figure it out so I decided to ask…
I just installed sense yesterday. 200Amp main service with the CTs clamped around the service mains (before the meter) since my meter connects to my panel via buss bars that I couldn’t get the CTs around due to the way the panel is configured. In addition, I also have Solar and have those CTs properly clamped around the wires that feed the solar breaker in the panel. Sense is reporting fine, no issues there. It did report an issue during the initial setup that it corrected itself which I believe is perfectly normal.
My question is simple… My solar is feeding 5,900W into my panel right now but Sense is also showing a draw of 2300W. I know I’m not using 8,200W so clearly I’m not understanding how this works… How can Sense detect load when electricity is being backfed into the grid? Shouldn’t the Sense app show a negative energy use? My meter says I’m feeding into the grid 3,600W so it’s reading the backfeed correctly. I guess I just don’t understand how Sense actually works… How can it detect load when my solar is generating more energy than the home is using?
