Heh. Truth. Heard about another incident with a 737.

Would tripping the breaker help the situation off grid? Are the short grid of a pv panel be enough to induce damaging current?

Tripping the breaker would theoretically protect you from DC induced onto your service drop wire, or if the solar storm DC on your transformer primary somehow shorted onto the secondary. I don't believe there's any reason to believe this storm could be so bad to do either of the above. That would require like thousands of times the power of the Carrington event or something.

But it's better than nothing if that's a good enough reason for you.

PV circuit is already DC so should not care about a little extra DC from the sun.
 
As of 2pm EST I am checking on my Ham Radio and there is no increase in the background noise.
So either nothing has reached yet or the numbers are exaggerated. I suspect that nothing has reached yet.

Thanks for the clarification. Do you mean transformer in the inverter?

I don't really understand the space weather terms but I guess we're waiting for the blue and green lines to take off here. I was excited about red line but I guess when I read the key, the different lines are power levels. So red line I guess is just measuring detections of still relatively weak waves.
