ssue Enabling Grid Self-Adaptation Mode on AC300

Dear @BLUETTI Support Team,

I am experiencing an issue enabling the Grid Self-Adaptation mode on my AC300.

The mode does not activate properly. In the app, the button occasionally becomes available, but it immediately switches back to disabled status.

Device firmware versions:
IoT: v9041.10
ARM: v4037.07
DSP: v4053.03

AC3002310000101512

The grid voltage is usually around 210–220V, but occasionally drops to 190V.

Could you please advise:

  1. Under what conditions this mode can be activated?
  2. Whether low grid voltage may prevent it from being enabled?
  3. If any additional configuration or firmware update is required?

Thank you in advance for your assistance.
