Charging

AC2A supports four charging methods: AC, solar, car, and generator.

Attention:

• Double-check that all cables are firmly plugged in.
• Avoid getting the plug and socket wet to prevent any potential damage.

AC Charging

Plug the AC2A into a standard wall outlet and start charging. Once it's fully charged, the AC2A automatically stops charging to prevent overcharging. For a fast charge, you can enable Turbo Charging in the BLUETTI App, which allows for an 80% capacity in just 45 minutes at an ambient temperature of 25°C (77°F).

Solar Charging

Connect the solar panels (in series or parallel) to AC2A via the solar charging cable. When receiving a continuous input of 200W, the AC2A will automatically stop charging within 1.5 hours. However, please be aware that the charging time may vary based on weather conditions, sunlight intensity, panel orientation, and other variables.
Note: Make sure your solar panel(s) meet the following requirements:
Voc: 12V-28V
Current: 8.2A Max.
Power: 200W Max.

Car Charging

Connect AC2A to the vehicle's 12V cigarette lighter port via the car charging cable. The AC2A can charge at a maximum of 96W, and it'll automatically stop charging once it's fully charged.
Note: Make sure your vehicle meets the following conditions for charging:

• The vehicle is capable of supplying power.
• The vehicle's engine is running during the charging process.
  

The AC2A has a low-voltage disconnect function designed to protect your vehicle's battery during charging. If the input voltage drops below 10.5V, the unit will automatically stop charging to prevent over-discharging and potential damage to the battery.

Generator Charging

Connect the AC2A to a generator via the AC charging cable. The AC2A will also automatically stop charging when it's fully charged, typically within 1.4 hours if the generator output is stable.

Note: Make sure your generator delivers the AC output with charging voltage, frequency, and Grid Self-adaption Mode voltage that meet AC2A's specifications.
If the total power demand of your connected devices exceeds the generator's output capacity, please turn on the Grid Self-adaption Mode to ensure a seamless charging experience.

Note: To ensure optimal performance, avoid short-circuiting the ports and keep them dry during use or storage. Additionally, do not block or cover the ports while ensuring proper ventilation.

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.

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.

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.

• 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.

Frequency Switching

The current output frequency (50Hz / 60Hz) is displayed in the lower right corner of the display. When the AC output is off, in the Setting Mode, press the AC Power Button to switch the frequency options based on your requirements.

Power Lifting Mode

The Power Lifting Mode is specifically designed to handle resistive loads up to 600W, including electric blankets, kettles, hairdryers, and other heating devices. To enable it, access the Setting Mode, navigate with the DC Power Button until the appears, and press the AC Power Button to enable the mode.
Note: The Power Lifting Mode is not enabled by default and is only suitable for resistive loads with a power rating between 300W-600W.
Although the AC2A can handle higher power demands, its actual operating power remains at 300W.

AC Charging Mode

The AC2A supports 3 AC charging modes - Standard, Turbo, and Silent to fit your specific needs. In the Setting Mode, use the DC power button to navigate until the icon starts flashing on the screen( P03 ). Then, press the AC power button to choose the Turbo mode.

Mode	Recharging Time	Note	Icon
Standard	2 hours	More friendly to AC2A's battery It can only be configured using the BLUETTI App.	None
Turbo	80% charge in 45 minutes; full charge in 1.4 hours	Comes in handy when recharging time is a priority.
Silent	4 hours	Offers a quiet, low-power operation for long battery life. It can only be configured using the BLUETTI App.	None

Grid Self-adaption Mode

If you're charging the AC2A using a generator or unstable grid voltage, and the total power demand of your connected devices exceeds the AC2A's input power, it is recommended that you enable the Grid Self-adaption Mode through the BLUETTI App to ensure a stable, safe charging experience for both the AC2A and your devices.

Exit Setting Mode

To save your AC2A settings and exit the Setting Mode, press and hold both the AC and DC Power Buttons at the same time.

Estimating Operation Time

To estimate the operation time of the AC2A, consider the load you're applying:

• For high-power loads (above 100W):
  Operation time = Battery Capacity (Wh) x DoD x η ÷ Load Power
• For small-power loads (below 100W):
  Operation time = Battery Capacity (Wh) x DoD x η ÷ (Load Power + AC2A Self-consumption)

Note: DoD refers to the depth of discharge. AC2A works at 90% DoD for longer battery life.
η is the conversion efficiency of the inverter, typically over 85% for AC2A.
The self-consumption of AC2A is approximately 7.5W.

E.g. If you have a 40W refrigerator, you can run it for about 3.3 hours. Operation time = 204.8Wh × 90% × 85% ÷ (40W + 7.5W) ≈ 3.3 hours.

Please keep in mind that the estimated operation time provided is for reference purposes and may vary based on actual usage conditions. Factors such as low temperature and excessive loads can significantly affect the battery capacity, leading to a reduction in the average operation time.

FAQ

Q1: How do I know whether my devices will work well with this product?
A: Please evaluate the total constant load of your devices. If it doesn't exceed the Max. output power of AC2A (300W), you can use this power station to run your devices.
Note: Some devices with built-in motors or compressors may start at 2-4 times the rated power, which can easily overload the AC2A.

Q2: Can I use third-party solar panels to charge this product?
A: Yes, you can. However, make sure your solar panels have an open circuit voltage of 12V-28V and are equipped with MC4 connectors. It's also important not to mix different types of solar panels.

Q3: Can it charge and discharge at the same time?
A: Yes. It supports pass-through charging. The AC2A comes with the premium LiFePO₄ battery and proprietary Battery Management System to ensure that it can charge and discharge at the same time.

Q4: Why is the charging power often too low?
A: AC2A has a built-in intelligent BMS that automatically adjusts the charging power in response to the battery temperature and SoC, thus protecting the battery and extending its service life.
