Deye Firmware Tracker Thread

Hello
I bought 2 model of Deye inverters
1- SUN-SG03LP1-EU 5KW with firmware HMI: Ver 0000-c358 Main: Ver 0-3374-1515
2- SUN-SG01LP1-US/EU 8KW with firmware HMI: Ver 0000-c35A Main: Ver 0-6014-1724

Is it essentially required to update them, and how is the procedures to do that through Solarman?
I appreciate your help
My problem is to read the parameters in screen with my BMS parallel felicity batterues ( read one battery only as total voltage 51.2 V)
I wonder if i update my firmware can solve this issue.

The firmware is updated by the factory thro Solarman they don't release it because some versions use the same hardware and KW are defined by firmware and they don't want us to buy a 5K and upgrade for higher without paying extra.
This is a normal procedure and it's good because if you don't buy the most powerfull of the line you know that your hardware can handle more than you paid.
 
SUN-SG03LP1-EU 5KW updated beginning of September

For those who can't change parameters via Solarman or Deye app you have to request Deye to allow that, in my case all the requests are made by seller and only takes a couple of hours to be active.

Other forum and confirmed by my seller, he also told me that Deye provide upgrades in power paying an extra, could be handy if we need a little extra but I prefer to know that I'm not at inverter max.

Funny story a guy in a forum complain that they install the wrong firmware placing a 8KW in is 5KW.

I have just been updated to C362 from C35C.

I have noticed the following changes to the HMI. If anyone can offer more information on any of these options, please do so.

Grid Set1:
New check box 'Unlock Grid Setting', when selected it asks for a PIN. I tried 7777 as the pin and it unlocked the grid settings.

Batt Mode:
New check box: 'Disable Float Charge' Seems self explanatory, useful for lithium batteries I guess.
New check box: 'Low Power Mode<Low Batt' Description from manual: if selected and when battery SOC is less then “Low Bat” value, the self-consumption power of inverter will be from grid and battery simultaneously. If unselected, the self-consumption power of inverter will be mainly from grid.

Batt Set2:
New check box: 'Low Noise Mode' supposedly this reduces inverter noise

Basic Set2:
New 'Language Select' Box with options for English, German, Hungarian and Spanish

Paral. Set3:
New option under Meter Select for 'Arcel-3P' meter
New check box: 'Grid Side INV Meter2' Description from manual: when there’s a string inverter AC couple at the grid or load side of hybrid inverter and there’s a meter installed for the string inverter, then the hybrid inverter LCD will show the string inverter output power on its PV icon. Please make sure the meter can communicate with the hybrid inverter successfully.

Wind Set2:
This setting page seems to be gone. I.e no wind turbine option anymore.

Does this mean that with the wifi dongle connected and up to date, the inverter will upgrade itself after 30 minutes?

Yeh just the micro inverters
 
Has anyone here ever managed to get the firmware and upgrade tool from Deye?

I emailed this morning saying my inverter was off-grid on land with no internet access. I await their response...

Yeh, they had trouble with connection with my inverters one time so they gave up and sent me the file and instructions on how to do it.
 
I have just been updated to HMI C362 + MAIN: 0-4384-1515.

C362 comes with the following functions (and others see point 6):

1) HMI: 0000-C362 MAIN: 0-4384-1515
2) Upgraded
3) Date of upgrade : 14.07.2023
4) SUN-6K-SG03LP1-EU
5) Single phase - 230V - 50Hz
6) See : https://diysolarforum.com/threads/deye-firmware-tracker-thread.39508/post-785489

My stick logger has also been updated from LSW3_15_FFFF_1.0.84 to MW3_16U_5406_1.57 (fixes important security issues).
 
Almost all computer equipment can be bios updated via a down load from the manufacturers website.
How odd.
 
Hello, which one is the latest firmware on SUN-5K-SG04LP3-EU inverter?
This is what I have:
