SP70 Solar Panel
1. General
Solar panels are a photovoltaic power source used for providing power to the
system, as well as charging lead acid batteries. The SP70 solar panel is supplied
with a 20 ft long, 16 AWG cable with two leads terminated with spade lugs. This
cable connects to the external voltage regulator. The voltage regulator is not
supplied with the SP70 solar panels, and must be purchased separately. The
SunSaver SS-10-12V voltage regulator (CSI p/n 18529) is recommended for use
with SP70 solar panels, and it can be purchased from Campbell Scientific, Inc.
The PS100 or CH100 can not be used with SP70 solar panels.
