And what does "phase" 2 look like on your oscilloscope?
What does "phase"1 look like on your oscilloscope?
I think you have some reading to do...
http://en.wikipedia.org/wiki/Split-phase
From the following link...
"A 60 hertz sine wave is synthesized that is in phase with the line and
they use PWN and a transformer to generate a high + and a high - bus
which is then ramped inphase from the high + bus to the low - bus,
through zero at a slightly higher voltage than the line so it feeds the
line. It must also detect when the array declines and change the pulse
widths to maintain the feed to the grid at the max while letting the
house eat what it wants as well. It also has the ability to feed the
line if you do not need the power and the sun declines and the array
does not put out the full voltage. Complex little devices, but just a
few LSI chips inside."...

You can get started with learning microcontroller programming here...

The "Basic Stamp" "What's a Microcontroller?" kit is also sold at Radio
Shack. This is the easiest microcontroller to learn on.
Then from there you can go to a Parallax Propeller Microcontroller which
can be programmed in assembly language. Here is a kit for that...
