I have had a solar power system using enphase mini-inverters for a little over a year. I haven't been terrribly active in radio over that time but did investigate the noise issue. I was concerned both about the inverters themselves and the powerline modem. I tuned my K2 to 10 meters on a day when it was very quiet and could not hear a difference between having the solar array active or not. I have never noticed any noise I could attribute to the system. My 'shack' is on the second floor directly under the solar aray. As they say, your mileage may vary, but don't think it's a serious issue. I don't know much about the Enphase communication between the inverters and the Envoy interface. They aren't very sharing of technical information. Since I did the noise test I had a problem with the reliability of the power line modem (unrelated to the test) and have gone to a wireles connection from the Enphase interface box (Envoy) to my local network, but that wouldn't effect the communication between the inverters and the interface.
