Electrical parameter matching
Voltage matching: The output voltage of the solar panel must be compatible with the input voltage range of the portable power station. Generally speaking, the input voltage of common portable power stations is between 12V-24V. If the output voltage of the solar panel is 18V, and the input voltage range of the power station includes about 18V, then the voltage is compatible. If the voltage does not match, it may cause failure to charge or damage the device.
Current matching: The output current of the solar panel must meet the charging current requirements of the portable power station. For example, the maximum charging current of the power station is 5A, and the output current of the solar panel should not be less than 5A to ensure normal charging, otherwise the charging time will be extended or even unable to be fully charged.
Interface type adaptation
Physical interface: Common solar panel output interfaces include DC interface, Anderson interface, MC4 interface, etc., and the input interface of the portable power station also has many types, such as DC5521, DC5525, Type-C, etc. It is necessary to ensure that the output interface of the solar panel and the input interface of the power station can be connected directly or through a suitable adapter. For example, the solar panel is equipped with a DC5525 interface, and the energy storage power supply has a DC5525 female socket. The physical interfaces of the two match and can be directly connected.
Power Adaptation
Solar Panel Power: The power of the solar panel should be selected according to the capacity and charging requirements of the portable power station. Generally, the more powerful the solar panel, the faster it can charge the power station under the same lighting conditions. For example, a 100W solar panel can charge the same energy storage power supply faster than a 50W solar panel, but factors such as the area, weight and cost of the solar panel should also be considered.
Power Station Input Power: The input power limit of the portable power station determines the maximum charging power it can accept. If the output power of the solar panel exceeds the input power limit of the power station, the charging circuit of the power station may be damaged. For example, the maximum input power of the power station is 100W, and the output power of the solar panel should not exceed this value.
