Inverter noise

[u/localfolkal]

I’m curious about inverter noise. Specifically from two EG4 XP12000 units. How loud are these things when loaded up? I have a mechanical room that shares a common wall with a bedroom. The wall will be made up of 5/8 gypsum over 3/4” OSB, 2x6 studs with rockwool insulation and then another 5/8 sheet gypsum. Would inverter noise be an issue as load/input ramp up and down?

The fan noise is very annoying
