@m.briney Yes, I updated the firmware to .10 Arm yesterday, but our weather has turned sour over here so it’ll be awhile before I can do any testing - need some sun! lol

@Jayling keep us posted! I’m gonna try and do more testing on it later with my variable power supply simulating Solar. We’ve got some nasty storms here in Michigan right now too!!

@m.briney I did forget to update this thread about the ‘Solar Input No Longer Working on the EB3A’. I was able to troubleshoot my way out of that problem. Here’s what I did:
Troubleshooting update -
Trying to find a way to reset that PV Undervoltage. Just turning the unit on and off then plugging in solar didn’t work. Took inside and charged up to 100% with the power cord, unplugged then ran it down to 97%. Took outside, power off, hooked up the solar panel and it began working. Actually got a peak of 99w input on that BougeRV 130w suitcase panel (loving this panel so far).
So by charging up to 100% via power cord and then running down the battery a bit then trying solar, it seems to have reset itself.
Since after that I had been scared to use AC and try to charge via solar at the same time, I put on my big girl pants the next day and tested again - first I made sure I was getting good solar input (90 some watts) on the unit with nothing plugged in AC or DC, unplugged solar input, then I plugged something into AC, and then plugged in solar - it worked without issue.

@Jayling hell yea that’s great news. 
sometime these units can be finicky and need that “cycle” to completely reset the internals. That along with them working on the firmware and putting out updates, are making this unit one of my favs so far!

Update: So far on ARM .10 it has been stable, no UPS issues so far. Will see how it goes the next few days.

Vinman, are you still using that external UPS device in between the computer/monitor and the power station, or is everything now just plugged into the EB3A?
I’ve removed it for now. My electronics are plugged back direct into the EB3A.

Hello all. I just received my EB3A and joined the forum. Before I ordered the unit I checked the forum and saw that some have had issues with the UPS feature functioning properly. This was a concern for me as I want to use the EB3A for a UPS for my desktop PC in addition to a solar generator. I also noted that some have updated the firmware and have developed other operating issues or the units have been bricked.
I ordered the unit from Amazon and it arrived on Tuesday. I downloaded the Bluetti app on my phone. The initial charge was 65%. I chargeed it to 100% using the AC wall charger. I then discharged it down to 5% running a AC fan using ~ 31 watts. I then recharged it to 100% using the AC wall charger. At that point the app activated and I was able to use the app.
I’ve tested the AC output and the DC usb ports charging phones and watches. All okay. I then tested the UPS function with a 9 watt led lamp connected to the unit. Plugged the lamp into the AC output and plugged the EB3A into the AC wall input. All good. Then unplugged the unit from the AC wall input. The lamp flickered briefly but stayed lit. Good so far but the real test is with the desktop PC. I plugged the desktop into the fully charged EB3A and powered it drawing between 45 and 90 watts. I then plugged the unit into the AC wall outlet and the UPS light activated on the EB3A. I was charging the EB3A and running the desktop at the same time (pass thru). Now for the big test. I held my breath and pulled the plug from the AC wall outlet and the desktop kept humming along without a glitch. It actually worked. Quite frankly, I was happily surprised. I repeated the power outage test multiple times with no issues.
I next tested the solar charging option using a Rockpal 100 watt portable solar panel. Connected it to the 8 mm input and it generated a maximum of 85 watts into the EB3A. I connected a fan to the AC output and it ran drawing 31 watts while solar charging. The solar charging test was a success.
The only issue that I noted (others have also) is that the the fan buzzes on fan startup at low rpm’s before it ramps up in speed. I contacted Bluetti and they advised that they are aware of this and that they’re looking for a fan replacement.
I’m running the stock firmware which came with the unit. It is “5702” and “5602”. As the unit operates fine for my purposes (other than the fan buzz) I won’t be updating the firmware.
Maybe I’m just lucky …

Thanks for the feedback.
To clarify your test did not deal with what the issue was. You have to leave your AC power device in permanently to the EB3A and watch for an AC disruption. Also a 9W lamp is not something that you readily tell if the AC got disrupted, you need something that cannot tolerate a disruption such as a computer,modem or router which will reboot or shut off if the AC is off for too long for its liking.
Removing the AC input cord to force it to use battery on the ineverter will always work but was not the issue. It was when you were using the AC in BYPASS mode (ac input) 24/7 the EB3A can temporarly lose AC to it’s AC outlets and relay will be heard clicking.

Thanks for the clarification Vinman. I’ll setup the EB3A with my desktop PC and see if it will run 24/7 while in by-pass mode without any interuptions. I’ll report back.
To be honest I updated my EB3A straight to .05 when i got it and then .09 and both firmware levels had issues. Not sure about .02 but if you start to have issues i would update to .10 ARM .10 DSP.
So far for me it is stable.

I’ve been running the EB3A in UPS mode for~ 3-1/2 hours using between 50-90 watts on my desktop PC with no issues on version .02. However, as you stated it has taken over one day before the AC output has dropped out. The EB3A gets warm ~ 105 degrees and the battery drops from 100% - 99%. When at 100% the input watts equal the output watts but when the charge drops to 99% the input watts increase to recharge the battery back to 100%. Do you think that I should update the firmware? How does the firmware get updated Thanks.
I’m charging using the low silent mode.
The UPS by pass ran for 13 hours on the stock version “.02” before dropping and turning off my desktop computer. I just updated to the latest version ARM 2057.10and DSP 2056.10. I also went back to standard charging mode. Vinman are you still running on version .10 directly into the EB3A without an aux. UPS? How long have you been running? Have you observed any other changes (positive or negative) using version .10? I should probably check my solar charging capability once again. As mentioned by others version .10 now allows one minute on the EB3A’s screen display (up from 30 secs.). Also went back to silent charging.
Correct as you experienced the same known problem with the UPS Bypass issue firmware prior to .10 DSP and .10 ARM. (more ARM fixed the issue). Also it fixed the solar input issue caused by the .09 firmware.
I now have my computer equipment plugged directly in the EB3A no issues with AC dropping out.
The EB3A will dip to 99 percent often and charge back up because the batteries will discharge as the internal electronics and BMS needs to run. You would think for 1 percent of charge it would charge at a low rate but here is where the past issue lies, it aggressively puts massive watts input to quickly overcome the natural discharge to get it back to 100 percent. This will be on going when on UPS BYPASS mode.
Firmware .10 sort of handles this aggressive charging cycle better so the AC inputs do not drop.
Running now on version .10 (DSP and ARM) for 13 hours with no drop outs. Set the charge level back to silent but as you stated it ramps up just to bring the charge from 99% to 100%. If all goes well through the night I expect to connect all of my computer equipment to the EB3A. Thanks for your input and suggestions. The EB3A has saved me from having to buy a new UPC while at the same time I have a nimble solar generator.
Great to hear!
Bear in mind it is a “poor man’s” UPS as there is no AC filtering like a true UPS but it is a bonus on this generator that some other generators don’t have.
Yes, a “poor man’s” UPS but the Lottery Dream House doesn’t appear to be in my future. lol
Hello all!
Very NEWbie here. I was Just wondering if this is still an issue, or did the firmware update fix the problem?
I am set to receive my EB3A tomorrow - I too planned to use the UPS function for my CPAP/BiPap. The CPAP will be drawing between 53w & 90w.
Hopefully the lack of updates in the last 29 days means Vinman’s last message - that everything was stable since the ARM 10 firmware update - is still, well, stable?
I have to advise that I’m not very tech oriented - in fact - this will be the first time I will ever have done one!? So, this begs the question: must I do all of the firmware updates in succession? Can/should I skip some, or do them all?
Thanks!
