Wondering how noisy a Fronius Primo inverter is?
They are this loud (click link for video):

Fronius inverters use a fan for active cooling. The stronger the sun, the louder they get. Fronius Primo inverters make much more noise than the new Fronius Gen 24 inverters.
They are silent when the sun is not out.
If you want an inverter that does not have a fan for cooling - consider an SMA or Huawei.
