Charging

AC70 supports four charging methods: AC, solar, car, and generator.

AC Charging

Plug the AC70 into a standard wall outlet and start charging. Once it's fully charged, the AC70 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℃ (77 ℉).

Solar Charging

Connect the solar panels (in series or parallel) to AC70 via the solar charging cable. When receiving a continuous input of 500W, the AC70 will automatically stop charging within 2 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 panels meet the following requirements:
Voc: 12V-58V
Current: 10A Max.
Power: 500W Max.

Car Charging

Connect the AC70 to the vehicle's 12V / 24V cigarette lighter port via the car charging cable. The AC70 also automatically stops charging when it's fully charged. On average, it takes about 7-9 hours to refill the AC70 using a 12V port and 4-5 hours with a 24V port at an ambient temperature of 25℃ (77 ℉).

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.

Generator Charging

Connect the AC70 to a generator via the AC charging cable. Under optimal conditions, it takes approximately 2 hours to reach a full charge at an ambient temperature of 25℃ (77 ℉).

Note: Make sure your generator meets the following conditions for charging:

• The generator boasts a stable power output that exceeds the charging requirement of the AC70.
• The generator delivers a pure sine wave AC output with voltage and frequency that meet AC70's specifications.

For stable and efficient charging, avoid using unreliable power sources like wind turbines. Also, it's not recommended to run your devices with AC70 while it's charging with a generator.

Discharging

AC Discharging

Note: Do not apply AC70 to loads higher than 1000W, as this may cause damage to AC70 and your devices.

DC Discharging

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 AC70 offers the convenience of adjusting its settings either via physical buttons or BLUETTI App. With the buttons located on the device itself, you have direct control over various settings such as ECO 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 AC70.

Setting Mode

When the screen is on and the AC output is off, press and hold the AC and DC power buttons for about 2 seconds till the frequency indicator flashes to enter Setting Mode.
Press and hold the AC and DC power buttons at the same time to exit Setting Mode.
Note: If you do not perform any operation in 1 minute, the AC70 will automatically exit Setting Mode and no changes will be saved.

ECO Mode

ECO Mode is a power-saving mode that is enabled by default. When operating on ECO Mode, the AC / DC output will automatically turn off if the AC70 is bearing low (less than 40W or the set power) or no load for a while.
Note: When connecting a small power device, disable the ECO Mode for a successful and uninterrupted charge experience.
In the Setting Mode, press the DC power button to enable or disable the ECO Mode. You'll see the icon displayed on the screen when it's enabled.

Frequency Switching

The current output frequency (50Hz / 60Hz) is displayed in the lower right corner of the screen. In the Setting Mode, press the AC power button to switch the frequency options based on your requirements.

Power Lifting Mode

Power Lifting Mode allows AC70 to handle high-power resistive loads up to 2000W, which is disabled by default. In the Setting Mode, press and hold the AC power button to enable or disable it. You'll see the icon displays on the screen when it's enabled.
This mode is particularly useful when using the AC70 with demanding heating devices such as kettles, electric blankets, and hairdryers. If the screen reads "OVERLOAD" while operating such devices, activating Power Lifting mode allows the AC70 to tackle these tasks effectively.
Note: The resistive loads should have a power rating between 1000W and 2000W. Although the AC70 can handle higher power demands, its actual operating power remains at 1000W.

AC Charging Mode

The AC70 supports 3 AC charging modes - Standard, Turbo, and Silent to fit your specific needs. In the Setting Mode, press the button to switch the options. Please refer to the below table for useful instructions.

Specifications

Troubleshooting

In the Setting Mode, press and hold the DC power button until an error code appears on the screen. Please refer to the table below for helpful guidance.

Estimating Operation Time

To estimate the operation time of the AC70, consider the load you're applying:

• For high-power loads (above 300W):
  Operation time = Battery Capacity (Wh) x DoD x η ÷ Load Power
• For small-power loads (below 300W):
  Operation time = Battery Capacity (Wh) x DoD x η ÷ (Load Power + Self-consumption of AC70)

Note: DoD refers to depth of discharge. AC70 works at 90% DoD for longer battery life. η is the conversion efficiency of the inverter, typically over 85% for AC70. The self-consumption of AC70 is approximately 15W.
E.g. If you have a 40W refrigerator, you can run it for about 10.7 hours. Operation time = 768Wh × 90% × 85% ÷ (40W + 15W) ≈ 10.7 hours.
Please keep in mind that the estimated operation time provided is for only 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.

FAQs

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 AC70 (1000W), you can use this power station to run your devices.
Note: Some devices with built-in motor or compressor may start at 2-4 times the rated power, which can easily overload the AC70.

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-58V 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 AC70 comes with the premium LiFePO₄ battery and proprietary Battery Management System to ensure that it can charge and discharge at the same time.

Q4: What is ECO Mode and can I turn it off?
A: ECO Mode helps save power, and you can turn it on or off on the screen. When operating on ECO Mode, the AC / DC output will automatically turn off if the AC70 is bearing low or no load for a while. You can set the power threshold of AC output and DC output to 10W-30W / 5W-10W, respectively, for 1, 2, 3, or 4 hours.

Q5: Why is the charging power often too low?
A: AC70 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.
