The "fix" of adding a motor run capacitor to the SW mostly helps with 
loads that that are sensitive to the SW's wierd waveform zero crossing - 
such as timers and such.  I have not seen it reduce audiable noise on 
motors or applicances.  

The downside is a substantial increase in the idle power consumption - 
as high as 50 watts with the cap installed.  Also - to large of a 
capacitor can result in "ringing" of the sinewave - causing excessive 
peak voltages which may damage some loads.    

My sources say that the SW plus has the same waveform as the previous SW 
series - so I doubt if any of the problems have been fixed.  It also is 
not offered as a utility interactive version - so no grid tie 
applications...
