July 20, 20232 yr Hi All, I posted last year about an annoying 15khz high pitched sound coming out of the sunsynk inverter. This was also coming out of my appliances and was driving me mad! I wanted to report that this issue has finally been resolved by sunsynk. you need to download the latest update and then get your installer to login to your profile. They then go to “plant list” on the sunsynk platform and click “low noise mode”. your inverter will then turn off for a minute probably with an error F13 (grid mode changed). It will then turn back on and the high pitched noise will disappear. They have effectively used a low pass filter and instead of the frequency being at 15khZ, it’s now at 20kHz which is just above human hearing.

I'm about to have two 12kW 3 phase Sunsynk hybrid inverters installed in the same installation. I have raised this concern with a few installers, but alas....
