Have been using the EB3A for backup AC power with my home router and internet connection and discovered that the AC output power glitches and interups about every 2-3 hours. Not sure if there is a firmware update to resolve this issue.
Anybody have a similar problem.
Hi @jdl84737, We would like to know if your EB3A has the ECO mode enabled. When this mode is activated, the output will automatically turn off after several hours of no load or low load. Please disable the ECO mode and then conduct the test again.
If the issue persists, please provide the SN code of your EB3A and the current firmware version. We will attempt to push a firmware update to resolve the problem.
Your cooperation in this matter is highly appreciated. Should you have any questions, please feel free to let us know.
The ECO mode was not turned on. Was using the EB3A for UPS backup with my home router and internet modem, about every 2-3 hours the AC power output would interupt and cause a reboot of the internet modem.
From what I’ve read the EB3A is a hot mess when it comes to reliability of UPS. They used a different batch of hardware components, with some users experiencing nothing but problems while others no problem at all. Another problem with EB3A in its design is the fan. It often likes to overheat. The other side of the coin is the UPS mode on the EB3A is not a true “offline” UPS. Even in UPS mode, the unit will use some battery power to run the circuitry as it cycles on and off. If this circuitry is not sound proof, it can cause the UPS to glitch and shut off. Bottom line, if you have a unit and it fails, you cannot reliably use it as a UPS. I doubt a firmware issue will fix it, if it is indeed a design flaw at the component level. Given the thermal design issues of the EB3A I wouldn’t rely on it at all to run components 24/7 off, just purely due to heat dissipation issues alone. In other words, you’ll have to use it only when you lose power for that short period of time.
Just for a comparison I ran my Dreo CF511 (AC) powered fan into my EB3A while recharging off solar in a camper that is only 75 degrees warm currently. It ran for 2 hours then shut itself off due to temp overload. Some have suggested using a small 5V USB powered fan mounted/taped to the side of the unit has helped with “keeping” it running, while also reducing the amount of errors in UPS mode, though it all boils down to “can you trust it?”
Does it show overload? Mine used to have similar behavior (showed overload and AC cut off). Requested a firmware update, and it’s been running non-stop for months (knock on wood).
This is the thread I requested the update in https://community.bluettipower.com/t/eb3a-shows-overload-when-not-overloaded

Hi @jdl84737, We want to push a firmware update to fix the issue. Could you please tell us the SN number and current firmware version of your EB3A?
Thanks to @rgb for sharing the successful experience!
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.
Serial Number: EB3A2330000287152
Firmware: ARM v2062.03 DSP v2056.13
Hi @jdl84737, Thank you for getting back to us so quickly.
Now I have applied to upgrade your system to our IT department. They 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.
Please let us know if it works.
I’m also dealing with a similar problem as this thread.
Whenever my EB3A has a load and is in UPS mode, it will click and remove power to the AC side for a faction of a second every few hours. It can happen more often rarely, but it’s usually once every few hours.
Serial: EB3A2333000804159
Firmware: ARM v2062.04 - DSP v2056.13
I have similar problem my case is when discharge at 49% it jump to 0% my Serial no is . EB3A221500016119 and firmware is ARM v2048.10 DSP v2046.10 please help
Hi @hamada, We regret to inform you that we do not have the corresponding firmware to push to your EB3A. In another post, we have already responded with a suggestion to perform a recalibration to resolve the issue.
For this issue, we recommend that you perform a recalibration. Additionally, regarding charging, apart from AC charging, we also suggest you try DC charging—specifically, solar charging and vehicle charging. We hope this helps.
Please follow the steps below to recalibrate it:
- Please discharge all the power (charge AC & DC appliances with the power station) until the SOC is 0%, turn off the machine, and leave it for 3 hours till it cools down.
- Please charge it again, please do not load any device when charging it, and do not interrupt it while charging.
You can click this link for reference.
Please let us know if it does help.
If not, please contact us for further service.
Could this maybe also solve the problem with my EB3A? it shuts down after reaching 100 procent charge since a few days now;-(. at the beginning of the problem, the only thing I had changed was charging mode from silent to standard… but when I now got back to silent, the problem remains…
EB3A2510000889741
IOT V9046.04
ARM V2197.02
DSP V2196.01
hope you can help me ;_)
Hi @TomPeek2, this kind of issue is very rare. Could you please confirm whether your EB3A shuts off the output or completely powers off after being fully charged?
Can it be turned on manually and work normally afterward?
Was there any load connected when the issue occurred, and did the app display any error codes?
If possible, please record a video of the issue, upload it to a cloud drive, and share the link with us — this will help us analyze the problem further.
Hi,
It shuts down the ac output and also "un"powers the dc output although the blue led of the dc stays on…
I can easilly turn the ac outlet on again, but this happens in the night or while I am away from home, so it is very inconveniant!!
However I turned the charging mode back to “silent” and shut the unit down and restarted it after some minutes and the problem has not occurred now for a bit more than a week.
If it stays this way, I can live with it, I’m using it as ups for my internet modem.
The reason why I turned the charging mode to standard was: I had a smaller window for charging with solar power and I tried to make that small window charge some more than before…
Now I made the period longer for charging from the grid, so I can make up for charging “silent” …
If the problem comes back (I surely hope not) I will get back to you again, thanks for your response anyway…
But If you think (or know) there is a newer updated firmware for me, I would like to try that ;-))
Best wishes,
Tom
