4. Connect the black (–) wire from the solar panel power cable to terminal

lug #3 marked solar (–) on the regulator. Connect the red (+) wire from
the solar panel power cable to terminal lug #4 marked solar (+) on the
regulator. If using a sealed rechargeable battery (BP24, BP84, or PS84),
verify that the metal jumper is installed to configure the regulator to
recharge sealed rechargeable batteries (see FIGURE 3-18). If using a
flooded battery (e.g., deep cycle marine battery), then remove the
jumper. Also note that no connections are made on the load terminals of
the regulator for this application (see FIGURE 3-18).

5. If charge current is available from the solar panel, the green LED on the

regulator marked “CHARGING” WILL LIGHT UP. This will verify
proper operation and wiring of the regulator.

6. To supply power to the system, connect the power leads from dataloggers

and sensors to the “load” terminals on the Terminal Strip Adapters
installed on the battery terminals, positive leads to positive terminal, and
negative leads to negative terminal of the battery.

The Morningstar SunSaver™ SS-10-12V regulator ships with
the jumper INSTALLED. If you are using flooded batteries,
such as a deep cycle marine battery, REMOVE the jumper
before installing the regulator.
