@Elliptica @DMA @Will2Power @sickburnbro solar is also likely to fail unexpectedly during periods of high demand
when there's a sudden surge of demand, the grid frequency is dragged downward, and inverters don't have the stabilizing effect that the gorrillions of tons of rotating mass in turbines and generators from traditional energy sources do.
chat, what do we do if we're a grid tie inverter and the AC frequency drops significantly below 60Hz? trip offline and throw an error code cause something's clearly wrong. better to disconnect than risk letting the magic smoke out of something expensive.
what does the sudden loss of a little energy source do to the grid? drop the frequency even further.
yay opportunity for cascading failure
