The SP20 sources more current than the SP10. Whether the SP20 is the best option for an application depends on the system. The SP10 sources sufficient current for many applications. Systems that use high current drain devices might require the SP20. For more information, see the "Power Supplies" application note.
Power requirements vary greatly across installations. For guided examples of how to calculate a station’s power consumption and determine battery and solar panel size, refer to the "Power Supplies" application note.
