EB3A in UPS mode turns off AC output shortly

Product Discussion BLUETTI EB Series
46

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 @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 ?

61

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?

63

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

I’m not sure if it’s okay to add my experience to this thread, or to create a new one, so forgive me for adding on!
I just purchased an EB3A from Amazon.

I’ve been using my EB3A as a UPS since I bought it, but it shut AC Power off after about 6 hours yesterday. It was on ECO mode, so I turned off ECO mode. Unfortunately, it shut off AC Power again sometime overnight. I had it connected to my home internet router and NAS, and was drawing about 74W continuously.

I don’t know if the new firmware update will fix the shutting-down problem, but I thought I’d let @BLUETTI_CARE know about it.

Serial: EB3A2440000044592
IoT: v9046.01
ARM: v2114.06
DSP: v2113.05

Now I have applied to upgrade your firmware. Our IT department will push the latest version of firmware to your unit in 24 hours.
Please upgrade the firmware tomorrow. Please do not load any device when upgrading it.

@BLUETTI_CARE
I have the same issue with my EB3A, purchased from Amazon. The first one worked as expected, then started randomly restarting the AC power while in use.
Serial: EB3A2337002662263
ARM: v2057.11
DSP: v2056.14

The 2nd unit has started turning off the AC power showing “Overload” even though it is only powering 2 security cameras, drawing a total of 10-12W.
Serial: EB3A2337002561884
ARM: v2057.11
DSP: v2056.14

The app does not show any firmware updates available for either unit.

Also, is there any way to limit the battery charge to 80% or 85% to extend the battery life when using it in UPS mode?
