I didn’t realize how troublesome this product would be. Recently had to use it when the lights went out for five hours. Still had a 30% charge in the morning … but …
When I went to charge it, it turned itself off. I assumed it was discharged but just misreporting. I plugged it in overnight and readout said 000 input 100% charged and 000 output. As soon as I disconnected form AC input, it died.
I googled it and found a dozen variations of the problem.
I put it on the DC charger overnight with no AC input. Readout was the same, but the unit did turn on and operate for about five minutes. I was able to connect with the mobile app, but not long enough to do any testing except turn the light on and off. Then it died.
I assume it needs to have an update, but how do I do that when I can’t turn it on? Very frustrating.
Hi @karlpalachuk
welcome to the bluetti community forum!
When i understand you right, the unit appears to be 100% but as soon you want to power anything or disconnect the AC Charger it turns off?
To help you as fast as possible, please write down the firmware versions of your EB3A to let @BLUETTI_CARE check for firmware updates.
Otherwise, they also can assist you with a repair or replacement.
How old is your EB3A?
greetings

Hi @karlpalachuk, We are deeply concerned about the issue you have raised.
The issue lies in the inaccurate SOC of the EB3A, which mistakenly believes it is 100% charged and therefore refuses to continue charging, while in reality, it is over-discharged.
Please plug the EB3A into the AC home grid, and charge until it is 100%.
After that, please turn on the AC and DC output of the EB3A. After 30 minutes to 1 hour, the EB3A will drop from 100% to 99% due to self-consumption.
After the SOC of EB3A drops to 99%, please disconnect EB3A from the home grid to see if the EB3A can be turned on normally. If so please AC charge the EB3A again.
Normally, the EB3A will work well then, and please tell us the EB3A’s SN number, DSP, and ARM version, we will push the new firmware to avoid this problem happen again.
We extend our gratitude to @Selfmadestrom for his suggestion and kind help.
How do I contact @bluetti_care other than posting here?
Here’s the unit info:
Bluetti EB3A
Purchased 2023
SN = EB3A2238002047631
ARM = v2062.03
DSP = v2056.10
Thank you.
I find it hard to believe that it is discharged since I’ve tried every combination of connecting to AC power source and DC power source (AC only for 24 hours, DC only for 24 hours, and both AC and DC for 24 hours).
This morning, I plugged it in to the AC power as suggested and turned it on. I was able to connect to the app long enough to capture version info. After about ten minutes, the unit shut down completely and will not turn on. My experience is that I need to disconnect from household power for several hours before I can turn it on for another 5-10 minutes.
