Is your Tesla inverter or Powerwall+ singing?

I've noticed a melody or two coming from my PW+, and I think from the inverter portion of it. It seems to occur about every 30 seconds or so. Is this normal? Video of melody below...listen carefully for 3 tones.

Thanks!

I could not really hear your video. But, my 2 PWs make a sort of a pulsing flying saucer sound sometimes.

Yeah you need to crank the volume... but you can hear fait short tones in his video. Very odd.

It's not an incessant BZZZZZZZ or the Enterprise whummm whummm whummm.

Ok. I have the Enterprise noise. Must be the warp cores making pulsing. Maybe in the PW2+ they use a different sound chip than my PW2.

I hear a similar sound with my non-Tesla MPPT (Maximum Power Point Tracking) charge controllers. I think this is the side of high frequency switching being done.

Just following up on this as Tesla sent a tech out to take a look. It turns out that one of my Powerwall+s was not correctly paired. He seems to have resolved the issue and my inverter is no longer emitting unexpected tones.
