Not necessarily. SS may have told them to use the updated firmware only on units destined for SS.
Now whether our trusty foreign friends uphold their end of the deal......

That's not how the Chinese operate.

Chinese business: "Yes, SS, we will honor our agreement."
Chinese government: "Share with your countrymen."
Chinese business: "Yes, exalted leader, we will share the technology with our countrymen."

SS doesn't feed or house the chinese people. When you are not free, you quickly learn to not bite the hand that feeds you.

Yep!
That is why as soon as one Chinese company starts to make something that sells well you will see five other Chinese companies start to make the same product. I also seriously doubt that SS is even buying a fraction of the Inverters that is needed to get their attention.

Home Solar is really not that big in America as it is in a lot of other countries and non certified DIY solar is an even smaller fraction of that.
I suspect that about 98% of people who get Solar in America are just hiring companies to install UL Listed equipment. There are not many people who are going to even think about fooling around inside a panel box with high voltage.

I actually have two of these. One from eg4 and one from megarevo. I am running into some very strange issues that I will share in a video soon. It's becoming an incredibly long video.

They are carbon copies of each other.

Sorry, EG4 is trying to play in a price class they have no business being in. The XW Pro 6.8kw is a far better piece of kit.

How so? I would rather have local support for this inverter than having to buy it overseas

Schneider has a large support structure in all major countries, and a quality / capability track record to boot. EG4 rebrands generic mass-produced chinese inverters that don't come anywhere close.

Obviously, this inverter is manufactured by DEYE. Anyone that has this rebranded inverter or its variations that can provide some overall input?

Will just made a video review of this and this and the Megarevo rebranded inverters here:

I have had 2 of these running for the past 7 months, and are now using them in parallel. I've been fairly happy with them, despite having near zero customer support.

I second that. The EG4 8kW is my third off-grid inverter and the best so far. I've had two different GroWatt SPF 3k versions, added an autotransformer to minimize light flickering, and gone thru the heartache of firmware upgrade, troubleshooting, etc. with the EG4 6000.

There is no LED light flickering with the 8kW. The load regulation is where it should be, i.e. a market-ready product. I have tried zero load, one LED bulb on L1 and 150W incandescent on L2, up to 7kW running all critical loads in my house and the voltages have been solid. That's true load regulation!

I have noticed LED lights occasionally blink on grid power now that I have learned to notice them. So far I have seen an occasional blink, not flickering, as well with the 8kW. My next step is to connect the grid to it to take advantage of its hybrid capability.

I have two GroWatt MIN 6kW grid-tied inverters that have served me so well since Oct 22, 2021. I got rid of natural gas. With no holdback on all-electric usage, charging my plug-in Rav4 almost everyday I still made an average $50/month. Unfortunately, my unlimited power buyback contract ended in Nov 2022.

I know this is subjective, but how noisy are these units (I mean actual audible noise). I have LVX6048s right now and they sound like jet fighters in my mechanical room even at idle.

Its a quiet unit. Mine is in a closet 10ft from my bed. You can carry on a conversation standing next to it. I can hear it, but the sound probably wouldn't register on a video if I took one. The fans ramp up when the water heater kicks on, which is the only real heavy load it sees. Even my A/C unit doesn't kick on the fans.

I want and need one of these, but after watching Will's YouTube video, I am not risking buying one yet. When you check EG4 website, they do not even have a firmware update for this unit. I will stick with my two 6500EX units for now. NOTE at one time the 6500EX said they would support Hybrid grid, but that has never come to light.

Why does it need a software upgrade? IMO, that's the culprit in most problems. An engineer, 3 levels down the chain thinks it's a good idea to install a new "upgraded feature" and breaks everything!

If you already own two 6500ex, I don't think this unit would ever be a consideration. There is no benefit, and in some cases you would be losing capability.

If you are just curious and have the backup, I would just purchase the unit directly from Alibaba. Save $1000.

I recently got my dual 8kw system operating but haven't got them in parallel yet. I can see in the menu under Setup, #15 is Parallel where you can select who is master/slave. Just wondering of the Sequence to tie in the slave unit. For now I'm guessing select the Master unit as Master, Slave as slave, shut down slave, close breaker where slave is tied to the panel where the Master is running at 240 Volts so the slave can see it's power, power up slave and it will automatically synchronize with the master and be online in parallel. Is this correct? I haven't seen any information on tying in the slave unit yet. Thanks.

How about you start your own thread? People can't find solutions when they are buried 42 pages deep.

There is a note that the Slave won't output power until it 'sees' the master. On the old firmware, I can turn each inverter on or off at random and the load never drops, it doesn't seem to matter. I never switch off the breakers to the panel. I'm not sure if it matters, but I haven't had an issue yet.

On the newer firmware, once one drops out, the other will reboot, then resume powering the load. Also, I've had issues with the new firmware not giving full power output in parallel.

The intertwining of Chinese OEM's and re-branded manufacturers is complex, but in this instance I believe DEYE and Megarevo are head-to-head competitors. Megarevo has no doubt copied DEYE features/format, as Shenzhen/Chinese companies are very good at this. But DEYE is normally very respectful of the SolArk's exclusivity granted for the North American market, so its is highly unlikely DEYE would contravene SolArk agreement by contract-manufacturing for another Chinese mfg (Megarevo) who has in turn white-labeled for EG4 in North America. The most important question is whether Megarevo, a relative newbie, can produce a quality product that meets the simultaneous demands of the grid-tie installer world and the DIY off-grid world . . . . gotta love the features, though.

I've got a Deye 8k from 2020. It's a rock solid piece of equipment that I wish I could get more of. I made the mistake of thinking that the EG4/Megarevo was a Deye with another name based on the seemingly same box. Once you see them side by side you know the difference. The Deye box is substantial. The EG4 box looks substantial in the pictures. Deye has a real GUI interface that is, in my opinion, better than Sol-ark, and a real outdoor box. My Deye has been running 24-7without a hiccup for almost three years now.The software on the EG4 reminds me of something that was available back in the 1990's. There is no GUI and it's confusing as hell. I'm finishing up a customer install of my first one and frankly I'm afraid to fire it up. After getting the conflicting input from Sig Solar on the not being able to communicate with their batteries so I have to set it to Lead acid to get it to work at 90% capacity. And then there's the stories about not being able to stop grid feedback, "this is a grid backup only install" so no Net Metering contract.
I have another one to install right after this one. Being over a week out in getting an answer from Sig Solar on a few of my startup concerns when they promised it would only be a couple of days at most, I'm feeling pretty edgy about these. I just watched Will's latest update video on it as well. He's on his third one and giving up on them.
