It is probably because of the extensive testing, certification, and liability issues of a device that connects to the utility company grid, and which has "potentially" life threatening implications if it fails to work as required. Something like the latest pill (such as Celebrex) which probably costs $0.10 to make and they sell for $3 a poop. (Oops, that's for a laxative!)
