I installed one such inverter on my home and, when powering it up without any consumers it has a light hum, no issues with that unless you stay really close to it.
If you turn on a few lights .. the same hum, still ok but when I start the computer (and I see the consumption around 180-190 W on the app) it starts to be really noisy (and the fan is off so the noise is not from it).
Is it normal? or should I return it?
Thanks!
