I’ve been using my new Elite 10 Mini for about a week. It is placed in my home server cabinet, and its intended purpose is to serve as a UPS. My setup is half off-grid, half on-grid depending on my solar battery SOC; my transfer switch toggles between the grid and the solar inverter. The signal flow is basically: Transfer switch output → Elite 10 Mini → 230V Load (max 100W).
The system ran well for a couple of days, but one morning I woke up to find the Elite 10 Mini turned off and the server down. I turned the Elite 10 back on; it was at 0% SOC and started charging. It took a few minutes before I could re-enable the AC output. I had no issues with the grid itself, as other loads not connected to the Bluetti had no downtime.
After this event, the Elite 10 worked again for a few hours, but then it started to discharge despite being constantly connected to the AC input. This time it dropped to ~60% and then recharged itself without causing downtime.
A few days later, it started producing E006 errors and cutting the AC output. This has happened 2 or 3 times now. I’ve stopped using it because every time the AC output cuts out, my server crashes, which is not ideal.
When the E006 errors occurred, the system was 100% off-grid, meaning the AC input was coming from my solar inverter. I haven’t had any issues with other loads connected directly to the inverter.
What could be causing these errors? Is the Elite 10 Mini unable to work reliably in bypass mode with a solar inverter input?

Mine has just started to have issues, I’ve had it for a month. Firmware fully updated. I too am using this as a UPS. I draw from 90w to 130w on average. 2 night ago it turned off AC at around 4am (Australian, Melbourne time)
This morning when I got up to check, it had fully depleted and was off. But I have a EcoFlow on the same circuit and no issues with it, also used as a UPS.
Since you’ve had no reply in 4 days I’m just going to send mine back and buy another EcoFlow. A shame, but being a month old and this has happened twice I’d don’t like to rely on this device
I’ve moved mine from the off-grid setup, and it has been on-grid for about two days now. No issues yet; let’s see how it behaves.
Mine is on-grid as a UPS for a home lab. But unacceptable for a device that’s a month old tomorrow. No more Bluetti for me. After the original AC180 I’ve not been happy. the 180 is a few years old and never missed a beat. A friend has the newer release and had to send it back twice in just under 12 months
Hi @JV16Bar,
Here’s what I was able to find regarding the error codes:
| Error Code |
Description |
Suggested Action |
| E006 |
Over-temperature protection triggered during charging. |
Allow the unit to cool down for a while, then restart the device. |
Please also make sure that the Bluetti Elite 10 Mini is placed outside the server cabinet to ensure adequate airflow and better cooling.
The temperature inside the cabinet stays between 19°C and 22°C, so I don’t think heat is a factor. I’m hoping this is just a firmware issue that will be resolved in a future update; I suspect the Elite 10 Mini is highly sensitive to the quality of the AC input.
Hi @JV16Bar,
According to the manual, the charging specifications are as follows:
Since it is already fairly warm inside the server cabinet and additional heat is generated during charging, the temperature could quickly exceed the specified limits and trigger the safety mechanism, resulting in error E006.
For that reason, this may not necessarily be a firmware issue. It could also indicate a faulty temperature sensor responsible for monitoring the battery cells.
In a typical UPS scenario why you need to charge / discharge the battery? In my opinion the power station should be in bypass mode.
Hi @JV16Bar,
I personally own an Elite 30 V2, which I also use in UPS mode. Even though the power from the grid is passed directly to your servers, the BMS still consumes energy from the battery itself rather than from the grid. As a result, the battery continues to use a small amount of power. For the Elite 10, this is approximately 10 watts when AC output (inverter), Wi-Fi, and Bluetooth are enabled.
There also seems to be a bug: if the battery is constantly at 100% (as is the case in UPS mode) with a stable load of 100 watts, and a sudden peak of 150 watts is required, the inverter handles this peak using the battery instead of drawing the power from the grid. You can clearly observe this if you use two separate smart meters: one on the AC-in and one on the AC-out.
Consequently, the battery is recharged in short bursts once or sometimes several times per hour.
It seems like the issues were indeed caused by the solar inverter. As long as I connect the Bluetti to the grid, it works as expected. However, I still don’t believe the Bluetti should be as sensitive to AC input quality as it has proven to be in my setup.

Does the E10 have grid self adaptation mode in the settings? That might help with your inverter input.
Yes it has grid self adaptation. Prior to start this thread I tried all possible settings, unfortunately none helped.
