Use of the product

Power-on/off

The main power switch controls the product to power on or power off.

Press the main power switch to power on the product.
In power-on state, long-press the main power switch for 2 seconds to power off the product.
In power-on state you can press the main power switch to make the display switch between on and off states.

After the product is powered on, the display is turned on, and the indicators on the top of the product are also turned on. If no operation is performed within 3 minutes, the display will be turned off automatically. In this case, you can press the main power switch to turn on the display. In power-on state you can press the main power switch to make the display switch between on and off states. After you press the main power switch to power off the product, the USB power supply, DC power supply, and AC power supply are all turned off. When all output switch are off and nothing is operated, it will turn off automatically after 2 hours.

DC output

Turn on the main power supply.
Press the DC output switch button. After that, DC output ports (including the car charger port, DC5521 port, and Anderson port) start to output power supply, and the DC switch indicator is turned on at the same time.
Press the DC output switch again. After that, the DC output is turned off, and the DC switch indicators are turned off. When the output of each 12 V DC port is less than 3 W for 12 hours continuously, the DC output switch will turn off automatically.

USB output

Turn on the main power supply.
Press the USB output switch. After that, the USB power supply is started, the USB-A and Type-c ports start to output power supply, and the USB switch indicator is turned on at the same time.
Press the USB output switch again. After that, the USB power supply is turned off, and the USB switch indicator is turned off.

AC output

Turn on the main power supply.
Press the AC output switch. After that, the 120 V AC output is turned on, the AC socket starts to output power supply, and the AC switch indicator is turned on.
Press the AC output switch again. After that, the 120 V AC output is turned off, and the AC output switch indicator is turned off. When the output of AC port is less than 15 W for 12 hours continuously, the AC output switch will turn off automatically.

You can press the AC output switch during AC charging to turn on the AC output to enter the EPS mode, and then the AC socket can take power supply directly from the AC input port. In this case, the power of charging and 120 V AC output cannot exceed the limit power of AC input (peak value < 1400 W); otherwise, the AC input may be disconnected for protection. In EPS mode, when the AC output power exceeds 1000 W, the AC input cannot power the battery, and meanwhile the maximum AC output power is 1100 W. In EPS mode, once the power supply fails due to abnormal AC input, the product immediately switches to battery power supply within 30 ms.

During DC charging, the 120 V AC can still output power supply normally, that is, charging and discharging can be performed simultaneously.

AC charging

After the AC input charging port is connected to the mains:

In power-off state, the product wakes up automatically and charges the battery in accordance with the preset charging power.
When the 120 V AC output is operating properly, it will switch to EPS mode for power supply and start charging the battery at approximately 300 W.

You can press the fast charging switch to cycle between low-rate charging and fast charging of AC input. After the power supply is turned on, low-rate charging is performed by default.

Note: When the AC input is connected to the mains, if you do not need to use the AC output, please turn off the AC output switch, otherwise it will reduce the AC charging power.
For the AC charging indicators, refer to the following table.

Pressing sequence| Screen display| Variable charging power| Full charging time
---|---|---|---
Default| /| ≤ 950 W| ≈ 3.3 h
First time| FC| ≤ 1400 W| ≈ 2.5 h
Second time| /| ≤ 950 W| ≈ 3.3 h

Anderson port DC charging

After the DC input charging port is connected to a car charger or a solar panel:

In power-off state, the product automatically wakes up and starts charging.
In power-on state, the product supports charging and discharging simultaneously

Note:
In smart car charging mode, if the car engine is not working, car charging is not performed so as to protect the 12 V battery. Car charging can be performed normally only after the car engine starts working.

This product supports the same type of solar panels. The company shall not bear the responsibility for any damage caused by improper operations or using different types of solar panels.

EPS function

In EPS mode, 120 V AC output is used, which preferentially gets power supply from AC input, and the battery is in standby mode.
After the 120 V AC output is started, the AC input is connected to the mains, the AC socket switches to the mains, and the battery is in standby mode.
When the AC input is connected to the mains, if you press the AC switch to start the 120 V AC output, the AC socket will directly take power supply from the mains.
When the AC input is abnormal and fails to supply power, the product immediately switches to battery power supply within 30 ms to maintain normal 120 V AC output.

Note:
The power supply in EPS mode involves switching time and cannot replace professional UPS products. When using EPS mode, you need to confirm whether the power demands of electrical appliances are satisfied.

To use the EPS function, ensure that the load does not exceed the rated power. The EPS function may fail to start when the rated power is exceeded.

Indicator

When the battery level is above 20%, the indicator is green.
When the battery level is below 20%, the indicator is red.

Long-term backup power mode

Long-term backup power mode: The product can be connected to the mains for a long period of time. The built-in intelligent system of the product automatically manages charging and discharging. If the product is not used for a long period of time, to meet the power backup requirement, the AC input port can always be connected to the mains, and it is intelligently determined that the battery is automatically recharged every 45 days. This mode is enabled by default.

Enhanced overload mode

Enhanced overload mode: For the load requirements, when a load exceeds the rated AC output power of the product, UPS protection is performed to output power supply for the load. In this case, the output power is limited to the maximum output power.
The actual loads that can be supported depend on the load types. This mode is enabled by default.

Automatic identification of power grid system

The power grid system is automatically identified in accordance with the frequency of mains charging.
When the AC output is turned on the next time, the product automatically switches to the frequency mode corresponding to the mains.
This mode is enabled by default.
