SP50-L/SP90-L Solar Panel
1. Introduction
Solar panels convert light energy to electricity, or specifically to direct current.
The direct current produced is used to provide power to a system and to charge
lead acid batteries. Solar panels operate in both direct and diffuse light, but not
at night.
A user-specified 16 AWG cable comes with each solar panel. External voltage
regulators, rechargeable batteries, and rechargeable power supplies must be
purchased separately. Please contact a Campbell Scientific applications
engineer to determine what components will work best for your application.
Campbell Scientific’s CH200 12V Charger/Regulator is recommended for use
with 12V sealed rechargeable batteries (BP12, BP24, and BP84). The CH200
with software version 5.00 or higher can easily be used with the BP84/PS84
battery (Concorde Sun Xtender™ PVX-840T) when configured through
DevConfig version 2.01 or higher. EnerSys Cyclon™ batteries can also be
used with the CH200.
CH200 OS version 4.0 can also be used with the BP84/PS84, but
requires each charging parameter to be set individually. See the
CH200 documentation for more information on setting charging
parameters. NOTE
The SunSaver™ SS-10-12V voltage regulator (CSI pn 18529) is another option
for these solar panels, and it can be purchased from Campbell Scientific, Inc.
2. Specifications
The SP50-L/SP90-L work with user-supplied deep cycle marine batteries, 12V
sealed rechargeable batteries (BP12, BP24, or BP84), 12V rechargeable power
supplies (PS84), and external voltage regulators (CH200 and Morningstar
SunSaver
TM (SS-10-12V).
