Hi @snmya, We fully understand how you feel and are more than willing to help. We have pressed the R&D department again to expedite the new firmware for AC200L and AC200PL to enable the System Switch Recovery function.
We hope to finalize this as soon as possible and will update this post promptly upon receiving feedback from the team. Thank you for your patience.

I have an AC300, AC70 and an EB3A that are all put in service as an UPS (given it was advertised to do so) and suffers from this problem. Are there recent firmware updates that fixes this problem and allow the AC and DC output to be restored when power comes back?
I’ve also ordered a APEX300, does that have the same issue as well?
Hi @BLUETTI_CARE ,
Thank you for looking into the issue.
Do you have any idea when the update might be available, please?
Thank you
Hi @snowstorm, We’re sorry that not all AC300 units can upgrade to this firmware. Currently, we’ve only completed the firmware for versions starting with ARM 4037, and the same applies to AC70.
Please provide the SN numbers and current firmware versions of your AC300 and AC70, and we will check if new firmware can be pushed.
As for EB3A, we haven’t developed related firmware.
As for the Apex 300, the new model already comes with the System Switch Recovery function pre-configured, which can be achieved without firmware upgrades. After enabling this function, when the battery level drops to 0%, the system will memorize the on/off settings of AC/DC.
- When the device is connected to an AC power source, once the SOC recovers to 5%, the settings will automatically turn on according to the memory.
- When the device is not connected to an AC power source, after the SOC recovers to 5% and the output remains off for 30 consecutive minutes, the settings will automatically turn on based on the memory.
By the way, please note that if you need my assistance, please @BLUETTI_CARE, otherwise, I might not see your message and be able to help you promptly.
Hi @Tezzabee, We have consulted the R&D department again, but they still haven’t provided a timeline for the app update function.
We’re sorry that we can’t give you a definite answer yet.

Here are the SN for my AC70 and AC300, can you check if an updated firmware to enable such system recover / memory function is available? The AC70 is used to backup a small freezer so this function is important.

Hi @snowstorm, Thank you for getting back to us so quickly.
We still need the current firmware versions of your AC300 and AC70.
You can find it on the Settings page.
Then we will apply the new firmware for you.
Here are the firmware versions of my AC70 and AC300, SN below. See screen shot for latest firmware installed.

Can you also advise what other commonly available Bluetti units have this recovery function to function as a UPS? Does the AC180 have it? If I buy a new AC70 today, would it have it too?
Thanks again for your help
Hi @snowstorm, Thank you for your attention to this matter.
For some version batches of AC70, AC180, AC18P and AC300, the System Switch Recovery function can be achieved by pushing firmware.
All versions of Elite 200 V2 and Apex 300 have this function built-in, and it can be enabled through the app without upgrading.
The version of your AC70 meets the requirements, so we have pushed the new firmware for you.
Now I have applied to upgrade your system to our IT department. They will push the latest version of firmware to your unit in 24 hours.
Please upgrade the firmware tomorrow. Please do not load any device when upgrading it.
Please let us know if it works.
The version of your AC300 does not meet the requirements, so we cannot push it for you.

Thank you, I’ll don’t see a new firmware available yet, but will wait a day.
It was mention that some AC180 and AC70 (the non P) have this capability to be updated. How do we know at time of purchase? Is there a date after in which all AC180 and AC70 would have this capability? As you can imagine, the ability to resume AC automatically after power failure and restoration is extremely important to use this as a UPS. Otherwise, it can be worse than not having it at all if you are trying to backup a fridge/freezer.
Добрый день. Скажите пожалуйста у меня bluetti ac 180 p.
Можно получить прошивку в которой есть меню working mode. У друга ac240p и это очень хорошо там реализовано.
