If so, it would be interesting to see the frequency stability of your inverter during a 24 hour period. If you run the Nano inverter, that test may be of interest to many who run your design. I see on my scope that the (off grid) instantaneous frequency jumps up and down a small bit but I'm not sure why. Not that it matters here - just curious.
