I have not noticed a problem with noise since I put our solar system in almost 7 years ago. No buzzing or humming at all. I have battery backup, but still connected to the grid also. Using Enphase micro-inverters, one for each panel to maximize efficiency.
Does a solar power home inverter negatively affect the sound of audio systems?
Michael Fremer’s wrote an interesting Stereophile article regarding the detrimental affect of his gas generator inverter on the sound of his audio system. Does anyone have experience with a solar power inverter and how it affected the audio system sound.
I think a lot of Mr. Fremer’s problems were related to the electrical ground in his older house. I have a house that was built in 1995 so grounding issues may not be an issue.
