New EG4 Firmware 18k,12k, Flexboss - FAAB-2525 and Gridboss - IAAB-16xx (9-28)

[CaySol]

Should you update the Flexboss first or the gridboss?

BTW, no need to unzip the DWIN_SET folder, just drop it on the root of your USB drive.

But the DWIN_SET folder isn't zipped, the instructions say to unzip https://eg4electronics.com/wp-content/uploads/2024/04/EG4-18kPV-LCD-Firmware.zip and copy the DWIN_SET folder from the "LCD V23_18kpv_12kpv_USB update" folder to the root of your thumb drive.

But then, it also says:
"NOTE: There should be 2 folders and one PDF in this folder."
which is clearly not true.

So once again we're left guessing and depending on Magical Thinking to make this work. "Make sure you do this in the afternoon, because I did it in the afternoon and it worked flawlessly".

I'm not even going to bother asking why the latest release is in a /2024/04/ folder on the server.

Attention to detail? What's that?

I did the Gridboss first but it does not matter.
You can also push the update to all 3 inverters at the same time.
If you have grid, bypass to that first so no interruptions.

Got me lol.
Unzip the folder and drop DWIN_SET into the root of the drive, no need to copy the individual files into the root.

Pop it in, light will blink, display will freeze after a few seconds and buttons won't respond.

The instructions say to power off the inverter, is this no longer required?

After about a minute, display will reboot and be on the new version.

If the display is completely unresponsive for <some amount of time>, you all should be more accurate about how long that time is, and highlight it in the instructions. You say 'about a minute', the instructions say 'several minutes (~3)', unless you set proper expectations users will be stuck waiting or will think something went wrong and power-cycle it again when it appears to hang.

And with that statement, you’ve summarized the root cause of almost all of the problems in this and other EG4 threads.

 

[Quattrohead]

Correct, one of the updates in the past removed this inconvenience, the display will now update as soon as it see's the files.
1-3 minutes for the update

Alright...I give up on the LCD update for now...something is borked outside of my power.

Fresh download of the files. Full "not quick format" of 3 different USB drives in both FAT and FAT32 format. Dropped the .zip and every "subfolder and file" into the main directory so it can find whatever files it needs 3x over, and still nothing but 3-4 blinks of the USB drive.

I even did a full power down to do it the "old way".

NADA.

WTF.

 

[blueforce]

Can anyone with a Gridboss report if the new firmware solves the issue where, when running in off-grid mode, the lights would constantly flicker. This line gives me hope:

• 8. Improved Busbar Logic for better system reliability.

Remote update it through the portal. or flash back to a older one and try again

tested and solved

Can anyone comment on if they fixed the AC Quick charge option clearing the AC charge enable bit?

@EG4SoftwareTeam can we also get the updated input and hold register PDF?

Did they also fix the battery backup mode, it sounds like maybe not - I've seen when the grid voltage dips the inverter fails to step in as well even thought I explicitly want the load terminals to be strictly DC coupled and am happy to take the conversion losses.

Is there a guide on how to do it for the LCD? I know how to do the 18kpv main firmware, but I can't figure out how to do it for the LCD update.

 

[Quattrohead]

FAT32 and all you should have on the drive is this folder.

I was referring to the remote update..

Was there a V20 LCD update? I'm on 18.
Curious to see if I can upgrade to that version and then move forward?

Does anyone have any archived LCD firmware files saved to share with me?

 

[Quattrohead]

Try the USB method again first. I don't think the remote option is available to the end user yet and it is slow.

Oh I've tried. I'm now up to 5 different drives.

I feel like I've taken crazy pills because I've done this for every single update in 2 years of owning this inverter with zero issues in the past

I just updated my 18k's this morning and according to my amp clamp, they're pulling a constant 600-700 watts per leg from the grid during self consumption mode with no indication of it doing so on the lcd.

Have you fully shut down the whole system for 30+ seconds and brought it back up? It does weird things until that's done.

Yes, I fully powered down for 15-20 minutes.

I think only I can do that, or tech support. My apologies, it just takes a while, 30min-4hrs, depending on connection speed and file. size of the course.

I'm up on 2525 / 1600.... The update process was definitely NOT so smooth - first the inverter powered off the loads twice per reboot - which meant 4 separate power losses of everything connected since it would have powered everything off ANYWAY to switch to bypass on the GridBoss. I don't think there's any way to swap to bypass without a full power loss to loads anyway, right?

But I had to wait about 10 minutes between the 25XX and the XX25 update, because it wouldn't initiate the update there. Kept getting an error. For whatever reason after about 10 minutes it accepted and did the xx25, and again multiple power losses. I know this is likely a communication reaction.

Why can't there be a command in the process that tells the GridBoss: "Hey, Mr Inverter needs to visit the little inverters room for a bit, put the loads on the grid until I get back and don't freak when I'm not communicating." That would be a lot more "polite" way to handle updates.

Anyway, after the inverter was updated and happy... GridBoss time. Try to initiate the update there, and I get another "failed" error - because while it LOOKED like it was online.... The dongle actually wasn't. I had to physically see that before I figured out why it still wasn't taking, 5+ minutes after the FlexBoss was back up. Don't know why, but there it was. Unplugged that dongle to reboot only it, and when it came back up, the update could be initiated.

Once THAT update was done, then it was time for a full dark shutdown of 5+ minutes offline. I took that opportunity to swap some wires around and brought everything back up - all seems normal at the moment.

If you're talking about the manual interlock on the GridBOSS, then no. That's an old-school manual interlock - it requires powering off the load but has the advantage that the most complex component of the entire thing is a circuit breaker so it is pretty bulletproof.

My update this morning went well. Using the web portal, updated the GridBoss. Once it came back online it was using grid to power loads, and PV power to charge battery. Waited 5-10 minutes to ensure it was all good (inverter never took AC load), and then triggered the FlexBoss upgrade. Waited for that to complete, come back up. Again, waited 5-10 minutes to ensure it was stable. Still was powering loads from the grid, PV power was only charging the battery. During this time I never fully lost power, it flickered, but didn't reset any clocks or devices.

Then completed a full reboot of both systems:
Turned off the GridBoss to grid breaker.
Turned off the GridBoss to Inverter breaker.
Turned off the inverter PV input.
Turned off the inverter battery breaker.
Waited until no lights on the inverter, and another minute after that.
Turned on the inverter battery breaker.
Turned on the inverter PV input.
Turned on the GridBoss to inverter breaker.
Turned on the GridBoss to grid breaker.

Everything came up well and it's been running normally since.

This update was not smooth for me. 4x12k and 1x18k - I had to power cycle the dongles as well as they did not automatically reconnect. I've reported this issue before, and suspect that @EG4SoftwareTeam and @EG4TechSolutionsTeam do not test with the ethernet dongle at all. It's really sad and because it's based on the WIZ-7500 there is less intelligence there.

I had to intervene physically on all the inverters and would end up in weird states like having EAAB-2522 firmware on the device.

The LCD update occured but the eg4 portal does not reflect that update, nor does it show up on the rs485 modbus side - Need to figure out why this is happening
