   – Fix the grounding post on the back of the station to the ground.
   – Press the “POWER” button on the front panel, and if the green light comes on, it indicates that the startup has been successful. Observe the screen to see whether the battery is fully charged. When the battery level is below 30%, it is recommended to fully
   charge it before use. When the product is powered on, the AC output defaults to on, and the DC/USB output defaults to off.

2. Charging Steps
   – AC charging：First, confirm whether the mains grid voltage and frequency are within the range of mains charging input parameters of this product. Second, confirm that there is no load on the AC output socket, and plug one end of the AC charging cable in the accessory into the charging socket on the back of the power station, and another one end to the mains power socket. Then, check whether the charging power and remaining charging time on the screen correspond to the product parameters. During the charging process, the AC switch on the screen must be in the “ON” state, otherwise it cannot be charged.
   – Solar photovoltaic charging： Please check the photovoltaic input voltage range before charging. After confirming that the positive and negative poles of the input interface correspond correctly to the positive and negative poles on the product socket, insert the input interface into the photovoltaic charging socket at the bottom left corner of the power station. Then, turn on the POWER switch on the front panel and check if the photovoltaic charging power and remaining charging time displayed on the screen correspond to the product parameters. During the charging process, the POWER switch must be turned on, otherwise the product cannot be charged (Ensure that there is sufficient sunlight when using photovoltaic charging).

3. AC Output On-load Usage
   AC on load: Before use, please check that the power range and voltage range of the on-load electrical equipment should match the output parameters of the station. Press and turn on the RESET button on the GFCI5-20R socket；Check whether the breakers at the side doors are all open. Insert the power plug of the loaded product into the output socket at the front of the station, and turn on the AC switch on the front. The load should work normally. Check the output on-load power parameters on the display screen.

4. DC/USB Output On-load Usage
   Before using the power station, please check that the voltage and the corresponding parameter range of the on-load electrical device are consistent with the power station. Insert the interface plug of the on-load electrical device into the corresponding interface in the front, and turn on the DC switch on the screen. The load should work normally. Check the output on-load power parameters on the screen.

5. Expandable Battery Usage
   Ensure that the specifications of the expandable battery are the same as those of the main battery. When the main and the expandable battery are off, insert one end of the expandable battery cable into the battery expansion port on the rear panel of the station and the other end into the socket in the expandable battery. Then turn on the portable power station and expandable battery switch in turn. Check whether the battery status in the main display is in the normal status, and the capacity deviation range between the two batteries should be within 10% before expansion (otherwise, the battery life will be reduced and other battery failures will occur during use). The expandable battery can be charged independently by the charger equipped with the machine, or can be simultaneously charged by the mains and photovoltaic with the main battery.
