I have the CH12R (12V charger/regulator). I am trying to connect it to a 17.5-V, 290-mA, 5.1-W solar panel, to keep a 12-V battery charged. I just wanted to know how to go about doing this.

Plug the solar panel leads into the CHG terminals, without regard to polarity. If using a 12-V battery that was obtained from Campbell Scientific, it has a molex connector that can be connected directly to the INT terminal on the regulator. For other batteries consider purchasing the external battery cable (part number 6186) that has a 10-ft lead that terminates in the molex connector.
