I didn't notice anything.Change log -
It is unlikely that we will receive it at least sometime in the future.
This is such a Chinese mantra

Deye's response when I ask for the changelog:
What a shame, this is not normal.
For laughs, I sent Deye support a request to receive the latest firmware for the 8K US model. Here's the response:
[Hi sir,
Solar ark is our USA solo agency.You can't use Deye Brand in USA market.
This is their website .They have USA Type grid model.
https://www.sol-ark.com/
Deye Tech Support]
They are very tight with their licensing agreements for the US. I'm curious if anyone has ever tried to install the US firmware onto the EU model, since they are the same machine (8K-SG01-LP1-EU/US).

I don't think there is a specific US firmware. As you said the 8K-SG01-EU & US are exactly the same product. Including for firmware matter.
Got a 8K EU, interface allows to select US grid settings.
- Ask the upgrade for a 8K EU
- don't mention that you are in the continental US but in PR where the 8K US is available

Could you share that upgradeprocedures.pdf ?
I'm not sure that there is no difference on the software side. I do agree the hardware side is the exact same setup. I've attached the screenshots of the screen for 'GEN PORT USE'. Although it will let you change the grid type to UL174, it looks like the EU version does not have some of the AC coupling features?
If you have an EU version, is there any way you can check? The latest firmware version for the US (according to the latest response above) is 36E.

Be careful, you should not confuse the HMI firmware (display user interface) which seems to be the same for different models and the MAIN firmware which is the most important and the core of the inverter and will be different from one model to another like for example all SG_6K.
So the latest HMI firmware is C36F the one I received yesterday.
I will communicate more information tomorrow on the flash procedure of the two firmware MCU1 (HMI) and MCU2 (MAIN).
Thank you for that detail. I did not know this.
So as I understand it, the MCU2 will determine what features are available on the machine. For example, the AC coupling feature in the US model is not available on the EU model and is determined by MCU2, even if the HMI are the same (i.e. 035E for both EU and US models).
Someone who knows about these inverters told us hat 5,6,8kw inverters are built with same hardware and the power limits are set by firmware. It makes sense because spec sheets for these 3 models mention that its same dimensions and weight. SG03 series
Maybe Deye will someday sell a firmware upgrade which unlocks higher power like Tesla is doing lol

I read this somewhere, too. I wonder whether it's the MCU or the HMI that controls these limits?

What is your HMI firmware version?

Quite old : C351. Not updated for more than a year
For information, attached is the PDF with the instructions (not very clear) sent by the Deye service.
In reality, here are the 4 steps to follow :
Instruction :
( the names of the .bin files are those that Deye provided for my inverter model )
I really like the pink underlined part, in reality I just think you need to make sure your inverter stays powered for the entire duration of the flashing, so if you have a battery there is no problem doing it in the evening.
In reality, here are the 4 steps to follow :
Instruction :
( the names of the .bin files are those that Deye provided for my inverter model )
- Go to the IP address of the WiFi module of the inverter (stick logger), login : admin\admin
- On the left, click the Upgrade inverter item (the inverter itself, not the Stick Logger firmware)
- Insert MCU1-SG-Ver0000-C36F-CK.bin (MCU1 = HMI) as the first file, click upgrade. We wait for 5 minutes.
- After rebooting, repeat the procedure, but now take the file SG_6K_MCU2_V4386-NR.bin (MCU2 = MAIN, takes more time...)

Ok thanks, straight forward enough 
Either the HMI is only a user interface regardless of the MAIN firmware behind it or the HMI firmware will display different types of information and options depending on the inverter model and the MAIN firmware installed which is more likely.

Deye 12kw 3-phase (3 x Inverters Total [3x12kW = up to 36kW], 1 x Master Inverter + 2 x Slave Inverters, Hard Parallel)
1) HMI 1001-C037 and Main 2005-1147-1807
2) upgraded firmware from HMI 1001-C031 and Main 2005-1124-1807 (this came out of my box)
3) 26 July 2024
4) Deye SUN-12K-SG04LP3-EU
5) 3 phase
6) Issues when starting up AFTER Upgrade, due to 3 Inverters in Parallel. See https://diysolarforum.com/threads/b...rs-in-off-grid-mode.70969/page-5#post-1159472 for more Information.
I'm still puzzled by the difference in Behavior before and after Update though. Before the Upgrade I could NOT start them one-by-one (switch each AC breaker one by one), after the Update I could NOT start them all together ! Which is a nightmare if I'm not home. The System won't be able to "self-recover".

Ah, so it's exactly the same!

Probably
You even have wiring diagram for both EU and US in both manuals for EU & US versions.
Guess the only real difference between the EU & US is they bundle 1 more CT for split phase in the US box ...

Could you post those docs and firmware files here?
Thanks!
So, the last HMI firmware is C370 now
It can be noticed that the MAIN firmware MCU2 contains the word 'US' and is therefore certainly different from the 'EU' version.
