I am still waiting on a refund from Solar Sovereign that was initiated by them over 10 business days ago. I have not been able to reach anyone and as of today when I emailed them, the email bounced back, and it says that email address does not exist. I have filed a dispute with my credit card company at this point.

I’d say they are gone. Their website doesn’t load anymore and their phone just goes to wait. I got an email saying they were refunding my purchase of a battery and 10 days later I did not get the refund so I contested the charge with my credit card.

Really enjoyed the breaking down of this unit. You do a great job of explaining your points, and always a joy to listen to!

I did a pre order on July 16th for delivery in mid August, waited til august 22 and contacted , said batteries just got in and would be delivered shortly. long story short, contacted them several times , they did up grade me to the version 2 eg4 , but did not receive until early October, but I did luckily get my order. Was getting concerned, but something is up with them. I heard they lost there deal they had with Signature Solar. All there EG4 items were off their site before I got my battery.

I ordered 18kpv and outdoor battery with them, after a month of nothing and about two weeks of multiple phone calls to see what’s going on and then trying to cancel the order and them saying “it will take a week for money to go back to your account” two more weeks go by no responses. I called my credit card and got a refund that day. It was ridiculous. I ordered from Current Connected and NAZ solar and big orders was sent literally next day. Didn’t order from signature solar because they charge tax.

Pls check Lithi2-16 manual on Ruixu website, Ruixu Lithi2-16 has E- stop function ,details on page 32

Great video, thanks for posting. I'm building a single inverter system very soon, it will be my first so I'm watching a lot of videos and this was very helpful.

Really appreciate the time you took to break down all of this for everyone. Although there may be cheaper batteries on the market, I love how you explained that the EG4 All Weather Power Pro unit is the best battery on the market 💪🏻. We love how EG4 made this battery with rapid shut down built in as well as being EMP hardened. Strongly agree that all of the built in benefits of this battery are worth every bit of the cost. Very effective video that will be eye opening for many!

Super clean install! Love your setup in the garage. Especially everything being raised due to your location. The wiring along with the conduit are very clean. Really appreciate you walking the viewers on how you did this. Very knowledgeable information. Thank you for sharing!

David - The cost of LiIon batteries has fallen 80% over the last 3 years and is predicted to fall another 50% in the next 1-2 years. LFP batteries are even lower cost. The EV guys are buying batteries at $60/kWh. Yes they buy huge volumes - but the fact of the matter is the BYD and CATL and others are selling for $60/kWh. At the RE+ show in Anaheim California one of the LFP suppliers for a major hybrid inverter company admitted that they were selling batteries for $80/kWh. Now I know there are some electronics involved and we are not talking about raw batteries - but the retail cost that you are listing per kWh are ridiculously high. Of course - 3 years ago SolarEdge installers were asking for $690 /kWh. My point is that the solar companies are gouging the Customers. We should all be pushing manufactures (by showing them the actual data for the actual cost of LiIon and LFP batteries) to be close to the actual cost which is $60/kWh today and likely to be $30 in 1-2 years. I know everyone has to make a profit - but as I stated - at least one of the suppliers admitted to being able to sell their solution (wall mounted) for $80/kWh. Lets press everyone to get their by simply pointing out to the sellers that the actual cost is closer to $60/kWh.

You gotta make a follow up video where you discuss UL certifications. Some batteries have no certs, some ESS solutions have the full cert and some batteries just have the 9540a. You might want to touch on whether an inspector will require the complete ESS to be certified. If so, you can only use the EG4 setup and only a certain inverter to battery ratio. What was the inspection experience like for your jurisdiction? You didn’t mention anything specific about Ruixu and free shipping/no tax. That can make a big price difference compared to EG4. Battery Evo / Big Battery have some sort of ongoing drama. I believe there’s lawsuits involved with IP and even LG has some sort of involvement. Battery Evo was also accused of using used cell packs in their batteries. You might want to touch on that a little bit. I got a price directly from GSL for a 14kwh IP65 and I remember it being $2750, all in, direct from China. The cheapest solution would be building your own box using a kit and buying cells from Docan Power. There’s an empty battery box from Yixang that’s already put together and makes the process so much easier.

The side of your condo box to get your battery water in easier. It will allow you to remove the plate.

Take the three little screws out of the bottom of your condo box and it will be easier to snap your battery wires in

Nothing says ‘rich rich’ like installing the outdoor batteries inside the house…

Great video

Love the attention to detail in this video. From the specs, to the internal components of the battery, to the charging and mounting. You really covered a lot here and this will be very informative and educational for anyone considering what battery would best fit their needs. The insight you've provided here is great and greatly appreciated. Can't wait to watch the rest of the series. Great job, David!

Nice video. Glad I could be of assistance. 😄

What is your total # of panels ? bi-facial/micro inverter? I use more panels to fight the monsoon overcast cloudy afternoons. Your quality of work inspire me to clean up my early work. you are inspiring and educational thank you for sharing.

These systems might be EMP hardened, (technically, all inverters are EMP hardened), but they're NOT EMP-proof. It's impossible to fully protect EMP-sensitive electronics that has an opening for a fan without using a Faraday cage, and these low-cost, Chinese made systems are not enclosed in a Faraday cage. Besides, the solar modules attached to these systems would simply act as an antenna that would pass the high current from an EMP pulse straight through to this low-cost inverter, which would instantly damage it. Sounds like EG4 has fed you a line of B.S.

You lost me in the first two minutes. No system can be completely protected against Lightning Strikes. EMP's Yes. depending on how strong it is. Lightning No.

what is the qf on your house

That's a very premium looking setup. Can you share what those or where I can find those tubes, accessories and wires that you've used? Thanks 😎

THANKS Coop ...

No offense to EG4 or David Neuman, but this still doesn't tell me much. I don't know what standard to which the equipment was tested. There is an old military EMP test standard from the early 1980s I think. There are far more powerful nuclear weapons making at least 10x more severe would be in order. Sorry it's been a while since I read all that so I don't remember the numbers and the details. -- However, knowing that they PASSED even the OLD test instead of NOT passing at all is still good. So thanks Mr. Neuman. Also, if you are up for more content you might do the deep dive on those tests for yourself and tell us all about it.

Thanks for another informative video.

Every time you make an addition to your system or an augmentation, are you modifying your interconnection agreement with Entergy?

Starting a large air compressor would be similar to the house starting a large inrush ac compressor.

A little tape on that old power feed to the shunt would be good

I don't know why anyone cares about EMP's if Nukes are being used you want to be vaporized.

I’m taking delivery this week for the 18k, power pro battery and chargeverter , I have been looking into emp shield but your saying it’s not needed ? Is this what I’m understanding, if it is , that’s great news but I’m just making sure?

You will never know until it happens then it's too late

WOWSER - Thanks for POINTING this out !!! I am quite happy with my SIX (6) EG4-LL 48-volt Rack-Mount batteries is this EG4-LL EMP hardening effective on both my 3 X EG4-LL (series-1) Batteries as well as on my EG4-LL (series-2) Rack Mount Batteries ??? up until now = I beLIEved the only difference was the FIRE-SUPPRESSION Packs in the SERIES-2 batteries ... PLEASE Advise Thanks again COOP the WiSeNhEiMeR from Richmond, INDIANA ...

Hi MSA. I don't know much about pools. Do most pool pumps have to run continuously? If yes, or no, I still had a brainstorming idea. If you rig a manual switch for the pump, you could rig some panels with microinverters tide in between the switch and the pump... as long as your panels/inverters are rated a little less than the pump's consumption. This way it won't back feed when pump is switched on. But, during daylight hours, you could really cut down the amount of grid use to the pump. And, it will free up your portable power station for other uses.

LOVE IT! Just a heads up, if you are making extended electric runs from your breaker box side, even shunt to ground of overvoltage pulse, if shunted in less than 2ns at source, is effective for about 250' of code compliant wiring (due to resistance of the wire). I looked over Element's test results. 20ns to 900+ns doesn't react fast enough within even 100' of wiring (although, the Eg4 systems should protect itself). However, an easy solution is to use EMP Shield's RV-plugin-portable at the end of a 120V phase's run, within 250' of the breaker box. Plug one into a zone on each phase leg, in the extended areas. EMP Shield's surge protectors were tested by Keystone Compliance with 40 repeated EMP (E1, E2, and E3) tests at 50KVM, then another 40 repeated tests at 90KVM (with no degradation of product). And it can handle a line surge up to 228KA. It's reaction time is about 1ns to 1.3ns, and resets in about .8ns after voltage is shunted away. So, if you want full peace of mind in protection from EMP/CME, it's great to double up. And, EMP Shield's products will still protect without power. The relay is powered by the overvoltage pulse, on every one of their products. The indicator lights are just to ensure correct installation. And... their products are for retrofit, so you can still protect non-hardened system. They make 37 different models to protect vehicles, home/business, and wind/solar/generator electric generation systems on every point of DC / AC parts to the system. I love redundancy.

I suspect they would give it a warranty for EMP attack even if they had no intention of honoring it; Because if the United States had an EMP attack all businesses including the plant where these are made would be all down and most of the population would die over a period of a few months... Having said that no warranty of any kind with any product or any business would be able to honor any warranty anyway. I think they are counting on that.

This is Truely awesome news for me....................When I get the chance,,,,,,,,,I Know what Im going to buy................................THANKS FOR THE GOOD NEWS........................

I currently have a Pwrcell by generac system, could I switch out my inverter and batteries for the EG4 equipment without having to redo my solar array?

This same inverter costs about 2200$ from luxpower from China 🇨🇳

He said Nothing new here. Sorry. Chinese are better at this.

I also have a solar addiction.

Energy security requires protection against multiple threats. Ensure EMP protection is robust with full spectrum of certifications and with US based monitoring and control.

Appreciate you sharing the gospel on the EMP hardening! We love that EG4 does there tests right here in the USA, as well as the fact that the price isn't being affected! Appreciate the graphics and humor as I found this information as wonderful to share. Can't wait to see the upcoming comparison videos. Awesome work, David. Keep it up!!

This may be new to EG4 but it is not new to the industry by any stretch. Many other companies have already been doing this.

Does this include the indoor eg4 wall battery

Having the right fusing and surge protection on most any system can make them hardened but no system will ever be completely EMP surge proof.. My gear is in the basement underground and has 4 separate surge protectors and ceramic spike protectors at every fuse that go to ground.. I pray we never have to test this out in real life.. They say the solar panels will survive but my guess is the diodes and or mosfets in the panels bridging will not survive.. So it would be a good idea to buy a bag of those if you are prepping for oh - sh*t day..

Good to hear!

Does EG4 provide warranty coverage for a system that has been hit by lightning, similar to the coverage provided by Sol-Ark for EMP inverters?

I will be hooking my EG4 chargeverter directly to my x6 rack Eg4s by passing Sol-Ark completely. Same boat as i need to add more solar panels as my system is 11.7 PV. My panal/pv installer advised if i add more PV that it could affect gridtie agreement with Duke energy and push me to a different tier which they then charge a reoccurring monthly fee. Painful! Dealing with energy companies and their strangle hold on power and us.

How do you have current CTs hooked up to monitor grid power. I have been in a conundrum as i have x 2 external 150 amp box main breaker boxes so assume i need 4 Cts.
