9. Settings
The AC2A offers the convenience of adjusting its settings either via physical buttons or the
BLUETTI App. With the buttons located on the device itself, you have direct control over
various settings such as ECO Mode, Power Lifting Mode, output frequency, charging
modes, and other functionalities. Additionally, by using the BLUETTI App, you can access
a user-friendly interface on your phone to conveniently monitor and control the AC2A.
9.1 Setting Mode
When the display is on, press and hold the AC and DC Power Buttons for about 2 seconds
till the output frequency flashes to enter the Setting Mode.
9.2 ECO Mode
The AC2A has two ECO modes that help you save power and extend battery life:
• AC-ECO Mode
In this mode, if the AC power output falls below or remains at a certain level for a set
period of time, the AC power will automatically turn off.
• DC-ECO Mode
In this mode, if the DC power output falls below or remains at a certain level for a set
period of time, the DC power will automatically turn off.
Attention:
• The AC-ECO and DC-ECO modes are enabled by default to save energy, and it's
recommended to keep them enabled at all times.
• Use the BLUETTI App to enable or disable AC-ECO Mode and DC-ECO Mode
separately. If you use the LCD display, they'll be turned on or off at the same time.
• To avoid any interruption in charging, disable ECO Mode when charging a small
device that consumes less than 15W of power.
In the Setting Mode, press the DC Power Button to navigate through the setting
items. When the icon flashes on the display, press the AC Power Button to
enable or disable the ECO Mode.
