MSX10, MSX20, MSX20R, MSX30R, and MSX50R Solar Panels
5
some batteries are discharged below a specified voltage, the battery becomes
damaged and cannot be recharged.
The battery supplies power directly to the operating system, the solar panel
supplies power to recharge the battery. Therefore, on the average, the solar panel
must provide at least as much power to the battery as is being used by the system.
The battery must have enough capacity to power the system during times of no
charging (night) or low charging (stormy winter days).
5.2 Voltage Regulator
The solar panel must be regulated either with a Campbell Scientific regulator or an
attached regulator. The regulator has two basic functions: 1) blocks any current
flow from the battery to the solar panel, and 2) limits the source current to the
battery.
The MSX10 is unregulated and must be connected to a Campbell Scientific
voltage regulator. These regulators include the PS100, PS12LA, PS512M,
CH12R, CH512R, CH100, CR23X rechargeable base, 21XL base, CR200 series
dataloggers, and the CR7 solar panel input.
The MSX20R, MSX30R, and MSX50R have a voltage regulator attached. These
panels are connected directly to a battery.
