I am an EE and have Tesla panels and inverter, but no Powerwall. I want to start a project that would allow me to use the power from my panels when the grid is "down". Of course, I would never back-feed a dead grid connection. But I have the following questions, someone has to know the answers.:
Does the Inverter determine when the grid is down by not producing any output near zero-crossings of the incoming power, and if the zero-crossings are not present, it assumes the grid is down and shuts off?
If I disconnected the grid "side" of the inverter, and instead drove it with a 60Hz sine wave, would the inverter start? How much power (Watts) would be needed to turn on the inverter? And if I simply made the output voltage of my sine-wave source larger than the maximum output voltage of the inverter, I assume that the inverter would not be able to back-feed my sine-wave source. But what IS the maximum voltage output of the inverter - 250Vm 255V?
I assume that PowerWalls have their own 5KW, 60HZ sine wave inverter. Is that correct?
