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
