Which is the lowest serial number that can be upgraded with the new firmware? Post it here so any AC300 owner can determine if their units can take that firmware.
Looks to me like if the ARM Version is 4037.** then you can update and if it’s 4032.** then you can’t. I haven’t seen any other ARM versions on the forums although the sample size is small.

Hi @Raymondjram, Thank you for your concern about this issue.
@Sideeffect’s explanation is correct.
Currently, only ARM versions starting with 4037 can enable this function through firmware pushing. Other versions cannot be updated yet.

May I ask please.
Is there a ‘System switch recovery’ upgraded firmware
available for an AC500 I just bought…
Or is it already a feature?
Thank you
(it is important)
(Didn’t get a reply/didn’t buy it, after all)
Dear @BLUETTI_CARE
This is great news, I’ve been requesting and waiting for this feature for years!
Please find attached the information about my AC300.
Thanks!
Hi @sebastian.stumpf, you are welcome!
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.

Can you tell me that AC300 units with ARM version 4032 will eventually get this feature? I bought mine new just last year, so surprised if it’s already unsupported for such a critical feature. Thank you.
Hi @ChickenLips, Thank you for your attention to this matter. However, your AC300 version does not support the System Switch Recovery function. We regret that we couldn’t be of more help.
Hello @BLUETTI_CARE !

So is this upgrade already in a system upgrade or do I need to send in my Product info?
I am about to install a SolarX
Hi @Yazz, the firmware for your AC300 has not been rolled out in bulk, and not all batches support the upgrade. Please provide the SN number of your AC300 and its current firmware version so that we can check for available firmware updates.

I just realized I will be away next week so if a system restart is needed and can’t be done remotely I would like to wait until 02/01/26 for any changes. My parents won’t know what to do. LOL
