Comment on Easy-to-use solar panels are coming, but utilities are trying to delay them

  You have a wire, it has voltage going through it, that means it has an EM field. We can measure said field in many ways. You can even measure this without needing to physically touch the wire. The absence of any electricity at all means no frequency, no em field. Put even 1mv through the wire and now it has an EM field.

  You have just measured Frequency vs No frequency. Why is this such a difficult concept to understand?

    This is not complicated, which is why I don’t understand why you’re having such a hard time.

    None of what you just said explains what the frequency is for a loose wire, or how an inverter would tell the difference between off grid and grid off.

      They would likely have two separate frequencies, a standard used nationally “On the Grid” frequency, and if you’re “Off the Grid” you would need to have a different frequency then what ever is used locally.

      You could use a device Like this to measure, or change the frequency of said wire.

        and if you’re “Off the Grid” you would need to have a different frequency then what ever is used locally.

        LOL again I ask, what is the frequency of a loose piece of wire? Let me go ahead and answer this for you this time: there is none. Which is why an inverter can’t tell the difference between being off the grid, and being on the grid with no power.
