Does a solar power home inverter negatively affect the sound of audio systems?

I assume these inverters create emi/rfi, in which case they affect whole house power quality. My own experience of using portable lithium ion battery supply to power certain components exposes flavoring, assume the inverter causing this. 

I do seem to recall a thread somewhere here where someone provided link to audiophile spec portable battery supply, inverter used boutique parts to suppress  self generated noise.

I think the devil will be in the details here. A typical gas generator likely has a poor inverter to generate the 110v or 220v output. I am always wary of connecting  electronics with circuit board directly to them for this reason. 
 

I have a relatively new construction solar home which has a large 48v DC battery bank feed by solar panels. I feed that to a large whole house inverter to produce 110v AC to run nearly everything. I have done no scientific testing but the system is dead quiet and no hum. 
 

I have not noticed a problem with noise since I put our solar system in almost 7 years ago. No buzzing or humming at all. I have battery backup, but still connected to the grid also. Using Enphase micro-inverters, one for each panel to maximize efficiency.
