EG4 Drops Nuclear News On Solar Industry

[42OhmsPA]

From the EG4 website here https://eg4electronics.com/emp-hardened/

EG4 took two approaches to its products to make its products EMP-hardened:
a) Physical metal fabrication such as enclosing critical electronic components in cage-like structures to reduce the impact of radiated emissions, and
b) Careful component selection and added additional protection techniques such as surge, impulse and EMI protection circuits to reduce the conducted emissions.

So EG4 added these features or they were / are in the Lux Power 12K as well?

Yeah, with all of the EG4 employees here, who's answering the phones?
This forum is turning into an EG4 promotional site.

Who designed and manufactures the batteries ?

Not sure if that information has ever been determined.
I only know that EG4 is not a manufacturer of anything.

Personally I wont be buying a EMP hardened product made in the country thats most likely to cause an EMP event in the first place.

 

[EG4 Electronics James]

Typo fixed

OEM/ODM relationship OEM funds, designs for end use, supports and defines improvements needed, ODM prov ides efficiency and expertise. It's been fun building the former. the report was done by us on our product. we defined the filtering and surge in the development stage before launch.

working on that too

it's after hours here, and EMI engineers aren't in tech support directly lol

Hey, friendly but serious comment - the report performed by Element needs to have the EAR/ITAR (google it) markings removed - or you could be visited by humorless Men In Black.

Pretty sure a boilerplate document edit from their typical business overlooked while preparing your report

Sure

Yeah so is charging peoples Credit Cards when you don't even have the Product in stock, yet here we are

Ha ha ha… it’s called float… good point.

All our Pre-order is clearly marked per FTC regulations, it seems to upset you that people disagree with your preferences so much that they buy the best deal in advance vs buy your high priced gear of choice which seems to always be on the shelves these days... Cheerio pal

It seems that this actual thread is making you uncomfortable enough to change topic.

Who designed and manufactures the batteries ?

The original EG4-LL was made by Gangfeng.
I stopped keeping track of who in China is making their stuff.

 

[Brucey]

working on that too

If this is alluding to possible US based manufacturing that would be exciting news. Versus the solark competition and their "designed and built by veterans" nonsense from earlier.

I believe their new lifepower 4 v2 is now built in same factory as their LL and power pro battery lines.

eg4 factory located in North Korea confirmed?

In seriousness though China is much more likely to send a remote kill command to scramble the brains of the China built AIOs versus launching a physical emp, if things get to that point. The true off gridders without cloud connectivity should be safe from that threat vector at least.

Seems like EG4 did not design EMP hardening into the product but was pleasantly surprised when it passed. What about the rest of the EG4 line? Should we expect more testing?

How much does this test cost?

EG4 would benefit greatly from testing their competition as well and reporting the failures, If any. For all we know, several inverters can pass this test already.

I would be stunned if the luxpower 12k didn't also pass the same tests.

Right. We kinda need a baseline of inverters that fail before we get too excited about 1 passing.

Having paid for these tests in my real job, $30-50k is a lot of money to put down only to find out you fail.
Proper planning and design and testing work up front ensure a successful test.
Sometimes you have to redesign on the fly and work with the lab until it passes.

 

[Plum Crazy Rob]

Also, while the unit was on the test bench, should have cranked the field strength up to 100kV/m, not just the 50 Mil-std requires. Sol-ark will still have leverage over you on this

It’s always nice to know your limitations.
Hey, with Sol-Ark, you can be a little closer to that detonation and still be fine! Sheesh.

We don’t know how many tests may have failed in the lab, because why report those?
Unlike military procurement, there is no high bar here for them to pass.
Any good news is great marketing.

I don't know why there is all the fuss.. If company X wants to market their product as EMP hardened and is losing sales to a competitor because they can't claim that what is harm in having a formal test to allow them to prove they can at least claim that now? Whether or not either company's tests is representative of real world scenarios seems like a separate issue.

 

[ricardocello]

¯\_(ツ)_/¯​

As I posted earlier, I’m going to have more pressing concerns than my inverter if we are victimized by an EMP from nuke detonated at high altitude. I’d rather put my money into better quality fuses and breakers and SPDs than into EMP hardening.

But everyone has different priorities, and if the market provides what they need, it is a good thing.

Apparently Solark claims over double the milspec standard, for their hardened version. $2000 premium for their option tho it does include a bunch of ferrites for solar panels and appliances to protect the whole system:
