I had to google it and apparently the complaints are:
Ruin the view,
Lower property values,
Habitat destruction,
Noise from inverter fans

> Noise from inverter fans
Not just the fans. The transformers, inductors, chokes, capacitors, etc can get extremely noisy as well. I have to plug my ears when I walk by the switchgear at my local Walmart's EV install because it is so loud.
Any system that relies on high rate of change of current over time is prone to these issues. Look at the prevalence of coil whine in gaming PCs and workstations now. The level of noise scales almost linearly with current up until you saturate the various magnetic cores. In a multi-megawatt installation of any kind that relies upon inverters, it is plausible that these electromagnetic acoustic effects could cause meaningful habitat destruction on their own.
Traditional synchronous machines (turbines) do not have this issue, but they are not something you want to live next to for reasons on the other end of the acoustic frequency spectrum. Infrasound from a turbine can travel for miles, especially during transient phases of operation. There were a lot of complaints on social media during the commissioning of a new natural gas generator unit in my area last year.
