[0069] In a possible implementation manner, as Figure 3 and Figure 4 , a DC input interface 101 is provided on the back surface of the base housing 10 for inputting external direct current;

[0070] The DC input interface 101 is electrically connected to at least one of the battery interface 30, the inverter unit 62, and the step - down unit 61.

[0071] In this embodiment, the DC input interface 101 can adopt a conventional interface for accessing direct current. The external direct current can be the output of photovoltaic power generation or other types of direct current. The inverter unit 62 can adopt a 2000W bidirectional inverter. The buck unit 61 can adopt a 500W buck module. In specific implementation, if the DC input interface 101 is only electrically connected to the battery interface 30, and the extended battery is a 48V battery, and the DC input interface 101 receives 48 - 60V direct current (photovoltaic), then the DC input interface 101 can provide the 48 - 60V direct current (photovoltaic) to the extended battery as the charging voltage; if the DC input interface 101 is only electrically connected to the inverter unit 62, and the extended battery is a 48V battery, and the DC input interface 101 receives 9 - 60V direct current (photovoltaic), then the DC input interface 101 can convert the 9 - 60V direct current (photovoltaic) into 220V alternating current through the inverter unit 62 and provide 220V alternating current to the outside through the AC socket 517; if the DC input interface 101 is only electrically connected to the buck unit 61, and the extended battery is a 48V battery, and the DC input interface 101 receives 48 - 60V direct current (photovoltaic), then the DC input interface 101 can step down the 48 - 60V direct current (photovoltaic) to 24V direct current through the buck unit 61 as the working voltage of the power supply processing unit 52, so as to provide direct current to the outside through the DC output interface 51; if the DC input interface 101 is electrically connected to the battery interface 30, the inverter unit 62, and the buck unit 61 at the same time, and the extended battery is a 48V battery, and the DC input interface 101 receives 48 - 60V direct current (photovoltaic), then the DC input interface 101 can not only provide the 48 - 60V direct current (photovoltaic) to the extended battery as the charging voltage, but also provide 220V alternating current to the outside through the AC socket 517, and can also provide direct current to the outside through the DC output interface 51.

The external alternating current can be 220V alternating current or 110V alternating current, etc., which is specifically determined according to the actual application scenario. The inverter unit 62 can adopt a 2000W bidirectional inverter. In specific implementation, if the AC input interface 102 is only electrically connected to the inverter unit 62 and the AC input interface 102 is connected to 220V alternating current, the inverter unit 62 can convert 220V alternating current into 48V direct current to charge the expansion battery; if the AC input interface 102 is only electrically connected to the AC power socket 517 and the AC input interface 102 is connected to 220V alternating current, the AC input interface 102 can directly provide 220V alternating current to the outside through the AC power socket 517; if the AC input interface 102 is simultaneously electrically connected to the inverter unit 62 and the AC power socket 517 and the AC input interface 102 is connected to 220V alternating current, the AC input interface 102 can not only convert 220V alternating current into 48V direct current through the inverter unit 62 to charge the expansion battery, but also directly provide 220V alternating current to the outside through the AC power socket 517.

[0075] It should be noted that when the AC input interface 102 is electrically connected to the AC power socket 517 and the third output control button 518 is set at the same time, the third output control button 518 can be installed on the connection line between the AC power socket 517 and the AC input interface 102.
