Re: KVAR units
I'm not sold on these units yet. As far as I can tell, they are little more than large capacitors that discharge when there is a sudden surge demand like a motor starting. Although they may have a big affect in industrial settings in controlling peak demand charges, they do not produce electricity or really save electricity they only level out peak demands. Most homes do not have enough motors kicking on and off to realize substantial savings, in my opinion.
