I recently purchased a BLUETTI EB3A, and I’m experiencing an issue where the unit powers off by itself—even while at 100% charge, ECO Mode disabled, and under a light to moderate load.
Here are the troubleshooting steps I’ve already tried:
• Disabled ECO mode via AC + DC button press
• Ran the unit in UPS mode, plugged into wall power continuously
• Tested with various loads (gaming PC, monitor, LED fan, etc.)
• Performed a manual reset (held power button for 10 seconds)
• Verified battery was at 100% during shutdowns
• Performed the entire Battery Management System reset twice (fully drain, fully charge, leave for 15 mins, then replug) and still didn’t work
• Attempted firmware update via the app but app said unit is using latest firmware version.
Despite all of this, the EB3A still turns off by itself — even when idle or under load. It appears to be a firmware bug or possibly a faulty AC output inverter or internal protection circuit. Please see attached picture the display on the front panel when it reaches 100% battery charge. Thank you.
Hi @Raffster, for this issue, we would like to try upgrading the firmware to fix it.
Please provide the SN number and current firmware version of your EB3A, and we will request the firmware push for you.
If the upgrade doesn’t resolve the issue, unfortunately, we may need to arrange for a repair.
Thanks to @Selfmadestrom for your help.
Mine did the same thing in UPS mode. Could never fix it. Despite support’s suggestion to update firmware, mine was already updated to latest version and it still occurred. I just gave up and kept it charged via the PV input source from a T200S DC charging brick I got from my EB70S. Translation = UPS mode sucks
