Does anyone have a solution to get rid of the high frequency noise that the PV solar inverter creates?
I can hear the low hum noise from the inverter as well as the fan, but the high frequency noise is a huge problem.
I have a Sunnyboy 3000 inverter. The manufacture, as well as the installers of the inverter, has no solution to this issue. ;(
We are considering the following:
1) blocking and or absorbing materials
does anyone have suggestions of what materials to use?
2) filter the high frequency, but how?
3) counter frequency, but how?
Attending rock concerts is not a solution. ;)
Thank you in advance for all and any solutions.
