For me the firmware settings are completely unavailable. I can maybe see the old firmware but there is no update possibility. Accumulating a lot of disappointment about this unit.Ordered one of these on a recent 'sale', which may or may not have actually been much of a discount, but the overloads are still occurring on new units with latest firmware. I also see power glitches on the AC that are sufficient to reset a connected PC when the unit is charging from DC.
Waiting for first contact from Bluetti support after sending them email today. BTW, I don't know if it's a recent change in the app (I'm new to Bluetti), but firmware updates to the device only seem to be available if you create an account.

Well, that is why I am disappointed. I have ARM 2053.07 and DSP 2052.04 and no possibility to update. I can see the firmware but there is no update button. In the old app I think it was but it got updated before I went through the updates.IIRC, the app did not even show the Firmware Upgrade panel in the Settings menu until I created an account and bound the EB3A to the account. If there are no updates available it only lists the "Current Version", which are v2057.11 for the ARM fw and v2056.10 for the DSP according to my app.
FYI, mine shows ARM version v2062.03 and DSP version v2056.10. Mine was delivered five days ago.Well, that is why I am disappointed. I have ARM 2053.07 and DSP 2052.04 and no possibility to update.

THAT is an interesting thought! So you think it is an overheat issue and might be caused by the 'minimum' fan level being unreliable because it's too susceptible to slight differences in fan resistance (to turning) and under some conditions might just be vibrating the fan a bit but not actually spinning it? Wouldn't it just try giving the fan more juice before it had an overheat fault?I think it is a low level PWM to the fan and the fan can barely start.
Not that I'm aware of. My personal early-production EB3A had two initial firmware updates when I first bought it and then none since-- I just checked last week. It may be that other EB3A's are getting them, but my personal unit is not.
I have owned four solar generators as of this writing. None of the others have ever gotten even remotely near as hot as my EB3A did after the brief power outage described above, though I noted no smell. It may be that mine is extra-bad somehow or perhaps there's more than one root cause of these problems, so that yours may well behave entirely differently than mine. Note that mine was at 100% when I found it, with the fan screaming along at the very top speed. Indeed, many EB3A owners seem to experience no problems at all, and I envy them. But after finding the unit so hot even just that one time I'll never attempt to use this specific power box in backup mode ever again. I still use the EB3A for other purposes-- it came in handy in support of a phone and laptop on a weekend trip just forty-eight hours ago as I type this. That one severe overheat, however, was scary enough that I'll never trust this individual, specific device again in backup mode, even for non-medical gear. I watch it _closely_ whenever I use it or recharge it, except when using a relatively gentle 100 watt DC source to recharge. (This is my normal method.)While monitoring with the Bluetti app, in AC UPS mode, battery @ 100% with 140W load, the battery will drop to 99% every 45 minutes.
At that point it draws another 100w from my (grid) solar for about a minute and a clicking sound can be heard in the unit. It then goes back to Grid = AC with battery @ 100. The additional draw from my solar can be seen in PowerWatch software.
Hopefully, it will not repeat again but I wasn't monitoring the solar output when it tripped last night.
The unit gets warm and emits an distinct odor.

Good luck!
Mine failed consistently with a 40 watt load. For what it's worth, as I said above Bluetti offered me a refund and I turned it down on the basis of convincing them that I was sincere and not just after a "free" replacement product. (Also, after waking up with my health at least slightly damaged and seeing so many other negative reports on the EB3A I'd never again trust an identical replacement for this purpose anyway, so why not save myself the trouble of the return and keep what I've already got since it works just fine for everything else?) I remain very concerned that people are going to rely on the EB3A for backing up the power supply of a CPAP, a usage case which Bluetti specifically and actively advertises, and end up dead as a result. I'm absolutely stunned to still see these things un-fixed, un-recalled and still being actively marketed for use with medical devices while the underlying problems clearly remain unresolved. I'm not an investor, but if I were I'd seriously consider shorting Bluetti stock. I think there's a very real chance of this all blowing up into a mushroom cloud of high-dollar lawsuits on them.The darn thing didn't last but 6 hours before Overload appeared while powering a 150w load on AC UPS mode
Piece of junk doesn't do the exact thing I bought it for.
Yep, nothing but problems with mine also. Soon after I got it, it decided to spontaneously discharge its battery bank with nothing plugged into it. Then, it wouldn't display accurate charge condition, so Bluetti told me to "train" the thing with charge/discharge cycles without any draw during charge. That helped for a minute but then it reverted to it's normal facocta condition. Then today "OVERLOAD" with only a single M1 Macbook Pro plugged into it. I'm done with Bluetti.
Yes, I sure did. That was the first thing I did. I had so many issues with this thing they have just offered to replace it, so maybe a newer version will be without the inherent issues. I'm not surprised they discontinued the EB3A. I'm aghast that Newegg is selling "reconditioned" versions of this thing that has so many issues.Did you update your firmware recently? That fixed my issues.
