SP5, SP10, SP10R, SP20, and SP20R
Solar Panels
1. General
Solar panels provide a photovoltaic power source for charging lead acid
batteries.
The SP5 has an output level that will allow it to be connected directly to the
“Charge +” and “Charge –” terminals on the CR200(X)-series dataloggers.
The CR200(X) will then charge a 12 Vdc (7 A h or less) battery attached to the
“Battery +” and “Battery –” terminals. Batteries larger than 7 A h are not
recommended as they may produce excessive heat on the CR200(X) circuit
board.
The SP10 10-watt and SP20 20-watt solar panels are intended to recharge the
gel cell lead acid batteries incorporated in the PS100, PS200, CR3000,
CR5000, CR7, and CR9000(X), as well as the BP12 and BP24 battery packs.
Either a CH100 or CH200 is also required when recharging a BP12 or BP24.
The SP10 and SP20 have two leads stripped and tinned to insert into the
terminals labeled CHARGE on the PS100, PS200, CH100, CH200, or
CR9000(X). The two wires attach to the green connector on the side of a
CR3000 or CR5000 datalogger. With a CR7, the two wires from the solar
panel are inserted into the terminals marked SOLAR PANEL located
underneath the 700X Control Module. An external gel cell or AGM lead acid
battery can be connected to the CR7 at the terminals marked EXTERNAL
BATTERY next to the SOLAR PANEL terminals.
The SP10 or SP20 must have a barrel connector (pn 788) to plug into the
retired 21XL Micrologger. See Appendix A for details.
The SP10R 10-watt and SP20R 20-watt regulated solar panels have two
stripped and tinned leads for connection to a user-supplied flooded lead acid
battery such as a deep-cycle marine or RV battery.
