I have the same question. From the little I've gathered, while it may be possible, it seems unlikely. The Ben Davidson guy in the video posted earlier said it was possible but would take a much larger storm than G5. I'm not sure of his credibility though, some of the stuff he said in the...

If I'm correct in trying to digest this, it's not so much the DC voltage amount going to the transformer that is the issue, but the fact that any is going to the transformer because it causes the transformer to lose the ability to limit AC power that comes from the source which will burn it out...

Who said this was going to end humanity in a few days? In this thread?

I believe we did not have the technology to detect the Carrington Event at the time and today we still miss about a third of CMEs from what I understand. You're right that the sun has been doing this since forever, but humanity has not been this technologically dependent. Humanity today is...

I'm not a bright man, but it seems obvious to me that the sun does in fact present a serious threat to our power grid. And a solar event could have a staggering impact on humanity. As in massive death. Whether that threat has increased or not due to things beyond my comprehension rotating and...

Is it your view that our current position in the solar cycle doesn't present an actual threat to the grid (and therefore humanity if it goes down in a big way), just as you were convinced computer code pre-2000 wasn't an issue?

Space Weather Message Code: WATA99 Serial Number: 7 Issue Time: 2024 May 11 1753 UTC WATCH: Geomagnetic Storm Category G4 or Greater Predicted Highest Storm Level Predicted by Day: May 12: G5 (Extreme) May 13: G3 (Strong) May 14: G1 (Minor)

So far, seems like no big issues with this storm. From this article:

We just switched to some portable Goal Zero stations for our power while the main system was shut down. From the attempt to learn about this over the past day or so, it seems that our 650 feet of wire is not considered a long wire. We found some research paper that leads us to that conclusion...

I went to my condo in Florida, or at least tried to, turned out it had moved to a new location so I couldn't find it.

Must have been.

I decided the best way to prevent problems was to connect to the grid? I'm off grid, I don't have the option of connecting to the grid.

Since I tilted the one array, it has consistently made about 50% more power than the vertical one now that the snow is melted. Once I get some ratchet adapters I'm going to tilt the other array as well. It has been of little import so far, we are running an electric heat pump and using our...

Nice, we did that. We have the 650' cable going to an AutoTransformer in our cabin (from the inverter) and then from the AT to the AC circuit box and from there to our outlets and to our heat pump. We unplugged everything from the temp outlets that go into the AC circuit breaker box. Then we...

My much smarter wife (much smarter, and I do mean MUCH smarter) is digging through this paper and on first blush it seems that our 650' of cable is likely not going to be a huge issue. But she's got to get through it all first and then explain it to me...

Book you and the lady a nice trip to Iceland in the winter. You'll love it and if you get out of the city, you'll see the lights.

I think you're likely right. This morning we disconnected our PV and our batteries. Shut off all c/bs and disconnects and equipment. But I still wonder if I even need to do that. I did it, just to try to be safe, but who knows. I left the inverter and MPPT and various transformers all...

Just was, the irony is we're still about five hours from sunset here...

I bet it does. Which excites me. With my career 3.0 gpa and very bad SAT scores....I'm really looking forward to trying to tackle electrical engineering (I don't understand) combined with geology (I don't understand) combined with physics and math and all thet....to see how I can keep my stuff...

Cool, I'll send him a private message.

You said "1-3 volts per kilometer of wire." You didn't mention kilometers of thickness in your formula. Thanks for your input though.

You think wanting to protect electronics from a burst of sun energy in a complicated area is being scared? I'm not sure you've ever been in an actual position that merited actual fear if that's the case. At any rate, don't mind the rest of us talking about this topic. Protecting investments...

Does it matter how thick the wire is? I'm completely scattered and ignorant and just finding little bits, but at this point in my jello understanding of this cosmic phenomena and electricity is that fatter cables with lower resistance are more subject to the effects of a CME. I've got 650 feet...

What does rarified air mean?

I hope this is right. I have 650 feet of 250kcml aluminum cable in our off grid system and I'm not sure if that's going to put my system at risk or not. Any idea?

Any idea how long is long? We taking hundreds of feet or thousands?

Just upgraded to G5.... We unplugged our batteries from all wires this morning and disconnected our solar panels. Shut everything down. Flipped all breakers and disconnect switches. Hoping that's enough...

Ah, I should have checked the General forum instead of the EMP forum. Thanks for pointing this out.

Any sense of what constitutes a long wire run? Hundreds of feet, or thousands of feet?

Just sharing for smarter people to discuss. I am much too ignorant to weigh in. But I like to be conservative so in the morning I'm going to power my system down, unplug the batteries and the solar panels. If all seems well late Saturday morning, I'll put the system back online. Gut feeling...

Appreciate it. I did the same using an Orion to make sure the power was set. It has been working great.

Battery voltage is above 49V so I'm not sure why this error came up. From the manual: Low Voltage: When the battery discharges to 44.5V or less, battery protection will turn on. Then there are the simultaneous "high voltage" and "low temperature" warnings. None of those should have popped up...

Engineer was too busy, so we'll get his info later in the summer and then order the metal and do the work. So, we're not there yet. Probably will order from Metal Supermarkets.

Got our Mitsubishi 12K hyper heat installed a couple of days ago off grid. Temps have been warm outside with lows of about 34F and highs in the 40s, but it has heated the cabin very well and sipped power. Looking forward to seeing what it does in the cold weather later this year. I'll put...
