    How do you detect the frequency of voltage that doesn’t exist? Hold a wire up in the air and measure the frequency and let me know what you find.

      I mean…if there is no grid frequency detected it automatically breaks connection between the house and the grid and keeps supplying the house from the panels and batteries. When it detects grid frequency again it reconnects the house to grid. It’s a fairly simple concept.

        Okay now try again but there is no grid.

      So you do realize that this is exactly how HV wire detectors work right lol… You hold up a wire (or there’s a wire in the wall) carrying high voltage, and the wand will pick up the EM Field.

              Because waves are frequencies. I wanted to encourage you to think about what your were arguing about.

                Right, it’s definitely not because you don’t know? Waves are not frequencies. Frequency is a measurement of how often something happens, typically measured in Hz. In the case of a loose piece of wire, there is nothing happening, and you can’t measure how often nothing happens. But thanks for confirming you don’t know.

                  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 difficult to understand, which is why I don’t understand why you’re having such a hard time.

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