All their chargers have overvolt shutdown but I'm using the SC48120-MPV's & they don't mention it in the specs but I had an overvolt shutdown happen presumably from a solar flare that jacked my panels past their normal VOC.
You're starting to get on my nerves! No dummie, a solar flare raises the voltage & likely the amps too, show me where that's not true, not just you're opinion.Huh? Now it sounds like you're making stuff up. The presence of light gives voltage. The intensity of light gives amps. A solar flare would result in greater intensity resulting in more power/current and likely LOWER voltage due to increased cell heating from higher intensity solar irradiance.
Sounds to me like you're pushing your controllers to the Voc limit and beyond.

Apart from the 1300 GW of globally installed solar PV capacity which has managed to survive all these solar flares...& of course there's no stats on how they react to solar flares
Maybe it was a lightning strike ...
Just to set the record on whether a solar flare can overvolt a charger, here's a post from a member that recorded a solar flare https://diysolarforum.com/threads/july-17-solar-flare-event.65867/ so yeah, if your volt input to your charger is not far off from it's limit, a flare can push it over the top. At max volts, I'm about 25 volts away from my chargers max volt input & a flare will run it into overvolts as my chargers have shown by shutting down during such events & sometimes on cloud edging too.Apart from the 1300 GW of globally installed solar PV capacity which has managed to survive all these solar flares...
Are you still running the setup shown in your videos where you switch in additional panels during low solar times? Potentially this is what smoked your three or four Victron 150/100s?Just to set the record on whether a solar flare can overvolt a charger, here's a post from a member that recorded a solar flare https://diysolarforum.com/threads/july-17-solar-flare-event.65867/ so yeah, if your volt input to your charger is not far off from it's limit, a flare can push it over the top.

& of course there's no stats on how they react to solar flares so you wasted your time for nothing & proved nothing. Go to bed, your brain is foggy.

But it's so much more interesting!When you choose to live on the edge.
You have to be prepared to suffer the consequences of going over that edge.
Oh, I agree that it is.But it's so much more interesting!
Looks no different to a cloud edge effect to me. And nowhere does that show a voltage spike occurring. That would be pretty unlikely, as that's not what happens when irradiance rapidly increases.Just to set the record on whether a solar flare can overvolt a charger, here's a post from a member that recorded a solar flare https://diysolarforum.com/threads/july-17-solar-flare-event.65867/ so yeah, if your volt input to your charger is not far off from it's limit, a flare can push it over the top.

No time wasted here because others (including myself) are interested in learning about the details sunshine put forth.& of course there's no stats on how they react to solar flares so you wasted your time for nothing & proved nothing. Go to bed, your brain is foggy.
Interesting. I wonder how so many over paneled growatts have been fried then. Their numbers are hard numbers without bufferAll their chargers have overvolt shutdown but I'm using the SC48120-MPV's & they don't mention it in the specs but I had an overvolt shutdown happen presumably from a solar flare that jacked my panels past their normal VOC.
Nobody should be running VOC with such minimal buffer that in JULY you exceed the charge controller specs from a solar flare…what ever would your system do on a cold bright January day?Just to set the record on whether a solar flare can overvolt a charger, here's a post from a member that recorded a solar flare https://diysolarforum.com/threads/july-17-solar-flare-event.65867/ so yeah, if your volt input to your charger is not far off from it's limit, a flare can push it over the top.
