EB3A in UPS mode turns off AC output shortly

Hi @Vovanu4, Our engineers have confirmed that your firmware is already up to date, so we are unable to push a new firmware update.

We would like to confirm whether you have enabled ECO Mode. If you have already turned it off and the issue persists, it may require contacting customer service to arrange a repair.

Hi @home99, We have confirmed that your firmware is already up to date, so we are unable to push a new firmware update for you.


Could you please let us know the specific load, including its power rating and parameters? Does the issue persist if you switch to a different load?


We recommend recording a video to show us the details of the issue and how you are connecting the cables. Please upload the video to a cloud drive and share the link with us. This will help us investigate the problem further.


By the way, please note that if you need my assistance, please @BLUETTI_CARE, otherwise, I might not see your message and be able to help you promptly.
That is the reason why we can’t reply to you in time.

I don’t understand why you say that I have the latest firmware, if I indicated that I have:
ARM v2053.08 DSP v2052.11
*
At the same time, just a little bit higher, the owners of the same stations wrote here, and they have newer versions, for example:
ARM: v2062.03 DSP: v2056.13
*
How does it work, and how the same model, may have different latest updates?!
How to understand it?!


We would like to confirm whether you have enabled ECO Mode

And I have never used ECO Mode!

Hi @Vovanu4, The DSP versions start with 2052 and 2056 involve different hardware batches, so the latest firmware versions are also different, but there is no functional difference between them.

The same applies to ARM or other firmware. These are separate firmware versions renamed based on hardware and batch differences, but each version has the latest firmware. If the latest firmware still cannot resolve the issue, contacting customer service for repair is the only option.

I have also reported this matter to the R&D department. They are actively discussing solutions and hope to develop corresponding new firmware in the near future.

Just discovered this thread while researching this issue.
I recently set up a spare EB3A to provide UPS power backup to my router and wifi accesspoint. I’ve seen that this 1sec AC power “reset” happen a couple of times throughout the day. The clicking sound is very apparent when this happens. Serial is EB3A2234004470713
Firmware says up to date
ARM V2057.11
DSP V2056.10

Is there a firmware I am missing?

Hi @bluetti_jkkwhotmailcom, I have applied to upgrade your firmware to our IT department. They will push the latest firmware version to your machine next Monday.
Please upgrade it then.
Please do not load any device when upgrading it.
Please let us know if it works.

Ok, so on Feb 10, I should check my app for a firmware update?

Hi @bluetti_jkkwhotmailcom, yes it is, we have pushed the new DSP v2056.15 and ARM v2057.12, you can upgrade it now.
I hope it does help.

Thanks, I just installed the updates. Will monitor and report back.

Hi @bluetti_jkkwhotmailcom, Thank you for your update.
We hope everything goes smoothly from here!
Please feel free to contact us if you need our help.

Hello, so far so good on the new firmware. For the last 48 hours, no disconnects have been observed. Thank you very much for helping with this!

I also have a backup EB3A, can I also request that the firmware update be sent to my backup device?
S/n EB3A2222005947463
Arm v2057.11
DSP v2056.10

Thank you!

Hi Bluetti Care, I am also experiencing the exact same issues AC resetting with click for 1 second.
I am currently running:
ARM: 2063.03
DSP: 2052.11
Says I have the latest update but this issue still continues, please can you push the new update to me: EB3A2321000522258
Thank you

Hi @bluetti_jkkwhotmailcom, Thank you for your feedback, we are glad to hear that!
We have requested that the new DSP and ARM firmware be pushed for your second EB3A. Please upgrade and test again.
Please do not load any device when upgrading it.
Please let us know if it works.

Hi @leewil1, We have requested to push the new DSP and ARM firmware for your second EB3A.
Please upgrade and test again.
Please do not load any device when upgrading it.
Please let us know if it works.

Thank you, I received the update but when I click it comes up with an error “Arm upgrade failed, firmware file error” ?

Hi @leewil1, It seems that the upgrade has failed, and there could be several reasons for this. Please help us troubleshoot the issue step by step.
We recommend fully charging the EB3A first. During the upgrade, disconnect all input and output connections. This means no charging and no load should be present while the upgrade is in progress.

  1. Update the Bluetti app to the latest version.
  2. Clear the cache and try upgrading again.
  3. Try using mobile data instead of Wi-Fi.
  4. If possible, test with another phone.

If the issue persists, please let us know the model of your phone.

Good morning, I have tried it on my iPhone 15 pro and my wife’s Samsung S24 both have the error. It must be something to do with the EB3A, is there a way to hard reset the EB3A ?

Hi @leewil1, For this issue, we have re-pushed the firmware. Please restart and try upgrading again.

Let us know the result after testing. If it doesn’t work, we will arrange a repair service for you.

Yes that new push worked, I am now on:
ARM: v2063.04
DSP: 2052.11
Is that correct?

Hi @leewil1, Yes, you are right, it’s the latest ARM version.
Does it help? We hope everything goes smoothly from here!
