Campbell Scientific has replaced the MSX-series solar panels with the SP-series solar panels. The SP10 and SP20 connect to the voltage regulator integrated into a PS100, CH100, or the rechargeable base of a CR5000, CR3000, CR23X, and CR7 datalogger. The SP10R and SP20R contain an on-board regulator allowing them to connect directly to a user-supplied external battery.
A Morningstar SunSaver regulator is available as an option for the SP65. This regulator is shipped with a 15 foot cable for connecting to a user-supplied battery and a mounting bracket for attaching to an enclosure backplate; the SunSaver regulator must be housed in an environmental enclosure. Two SP65 solar panels may be connected to a single regulator to provide 130 Watts of power.
