Top comment says it all:

Like every new battery announcement, Ill believe it when I see it in production at scale. Have they really solved the issue of Si expansion? Tesla thought they had it solved and they apparently didnt. And is it cost competitive? If it costs twice as much existing cells, it likely wont make much impact except in aeronautics where weight is more important than cost. How is cycle life? Im very skeptical of new battery announcements at this point. I wish them well though!

Thought I'd add these here as well. They've mostly sold phones in SA in the past, but they have also been making powerstations for sale overseas for a while.

I'm am starting to see the overload issue (hardware problem) on Ecoflows FB page almost daily. Very concerning.

what is the highest you've seen it? I saw 250v at someone recently.

245V but I have seen it drop to as low as 190V in the past.

Most units are able to function under a wide range.

My Kool 1KW for example:
AC INPUT.

  • Mains charging current: 10A.
  • Input Voltage Range: 145-275V.
  • Input Frequency: 45-65Hz.

That said I have both surge protectors and a Sonoff POW's on my inverters. (Both protect under/over Voltage & current)

They don't have this problem at this scale in any of their other markets. It's a uniquely South African issue.

I am not so sure. Maybe they don't have loadshedding and users that use them as EPS/UPS at this scale in other markets either.
 
Disconnect the device from the mains before load shedding ends.

Some users report that it happens when loadshedding starts. Need more people to confim.

Usually one knows when it starts, hence disconnect it then. I got a Delta 2 a few days ago. I recharge it at 500W and then disconnect it. Otherwise if left plugged in, even without load, it heats up and fans spin up now and again, even when not charging.

So you mean other countries don't have load shedding? It's just us? Weird, wouldn't that make it unique.
 
AFAIK the possible problem is not continued high or low voltages, it's a spike during the 1st second when power returns after loadshedding.
I've installed a timer on my main feeder from the council that delays my switch on by 40sec.
Have never had any problems.
Interestingly enough, the same device also protects me from longer term over- or under voltage
