Bluetti EB3A randomly shuts down in UPS mode

I bought this power station to supply power to my boiler pump. The pump’s power consumption is 60 W. Eco mode is disabled, but when the main power goes out, the station turns off and does not power the pump.

I need to fix this issue because my apartment will freeze. What should I do? What other information about the power station do you need me to provide, and where can I find it, so that you can send me an update that will help fix this issue? EBЗА2524000669402

@BLUETTI_CARE help me

Hi @arturlegencuk, we would like to help you.
May I have the current firmware version of your EB3A?
Then we will check if there is any new firmware available.

@BLUETTI_CARE I can’t check it now, but 2 weeks ago I installed the latest updates and yesterday there were no new updates, so I can say that now there is the most current firmware version

Hi @arturlegencuk, we have some new firmware that hasn’t been released for batch update yet. We need your current firmware version to push it to you individually.
Please provide your current firmware version at your convenience, and we will apply for the push for you.

Hello @BLUETTI_CARE,

I am experiencing the exact same issue described in this thread. My EB3A randomly turns off the AC output which is enough to shut down my connected monitors and equipment.

The issue occurs when:

  • The unit is connected to the grid
  • Battery SOC is at 99–100%
  • Load is well within the 600W limit
  • No error codes are displayed on the screen

Troubleshooting steps I have already completed:

  • Disabled ECO mode
  • Disabled Power Lifting mode
  • Switched from Silent to Standard charging mode
  • Verified AC frequency is set to 50Hz (matching Chile’s grid)

None of these steps resolved the issue. The AC output continues to drop randomly during the 99%→100% recharge cycle.

Device Information:

  • Model: Bluetti EB3A
  • Serial Number: EB3A2516000776959
  • IOT: v9046.04
  • ARM: v2197.02
  • DSP: v2196.01
  • Region: Chile (50Hz grid)

I have seen in this thread and on the firmware thread that Bluetti has developed targeted firmware updates to address this specific AC output shutdown issue in UPS mode. Could you please push the latest corrected firmware to my unit?

Thank you for your help.

Hello @orhan ,

Thank you for your patience and for providing such detailed information.

We have successfully pushed the latest ARM firmware (v2197.03) to your unit . Please update the firmware via the BLUETTI app and let us know if the issue persists.

I’ve updated now. I am testing again with Grid connected in UPS mode while AC is ON and my monitor connected to the Bluetti EB3A. I’ll see if it is going to shutdown the AC again while battery is going from 99% to 100% or not and write here back.

For my 1 hour test, it looks like the issue is fixed with the ARM firmware (v2197.03) update for my device. What I mean is that the battery is charged from 99% to 100% and stay on 100% for about now 20 mins on UPS mode and AC is ON - AC is not shutdown now. I’ll be testing and monitoring for a couple of days and write back here. So far, thank you for your support on this.

This is the half of my 3rd day testing the latest ARM firmware (v2197.03) update with UPS mode ON, AC ON, connected to GRID. Now it started to shutdown or turn off briefly the AC while the battery is on 100% and then turning on the AC instantly in about 2 or 3 seconds automatically. My external monitors that connected to the Bluetti EB3A Turn OFF briefly and Turn ON again automatically in 2 or 3 seconds. This is a new strange behavior. The AC load is 80-85w, Grid load is from 80w on UPS mode synced with AC but when charging of course it goes up to 250w to 275w etc on Standard Mode.

Is this behavior normal on UPS Mode while the AC is ON with connected devices?

Hi @orhan, thank you for letting us know.
We would like to know whether the AC output button light and the AC icon on the screen both turn off at the same time when the issue occurs. It would be best if you could record a video, upload it to a cloud drive, and share the link with us. This will greatly help us analyze and troubleshoot the problem.

Hi,
No the AC output button light (green) is ON, AC is ON on the panel screen and also on the app screen at the same time when the issue is occuring. I’ll record a video today and send back ASAP.
Thank you
