This is an attempt to test out a theory that a synthetic sine wave can be used for solar power diversion in a similar fashion to Robin Emley's design (calypso_rae on Open Energy Monitor Forum July 2012).

Inspiration by pmcalli (Open Energy Monitor Forum Sept 2012).

The circuit is using a zero cross detector (trigger on positive volt crossing) on the voltage waveform (connected to INT1, PIN 4 on CPU).

If this design works, solar PV diversion could be made without expensive (or accurate) transformers.

You can ignore the OPAMP GAIN sections from the code below if your not using any Opamp circuts.
