This may nor may not be related to my Tesla, but my solar installer seems to think its a possibility. I have solar panels with microinverters that communicate over the powerlines to a central enphase envoy monitoring device. Recently they seem to have issues with the signal and although the panels are producing, they are not reporting the data. Its happened a couple times in the last month. The most recent electrical changes seem to be the addition of the 50amp, 14-50 outlet and occasional car charging. The communication issues do not correlate with car charging times. My solar folks are not knowledgeable enough about the car charging, and the regular electrician isn't as familiar with power-line networking or data communication. I'm sure I'm not the only one with a Tesla and microinverters that communicate to a central monitoring device.
