SP70 Solar Panel
3.4 Installation of Morningstar SunSaver SS-10-12V Regulator
For safety reasons, completely cover the solar panel to limit
output current and voltage. If nothing is available to cover the
panel, be careful not to short solar panel (+) and (-) leads
together. NOTE
1. Using the supplied mounting hardware, install the Morningstar SunSaver
SS-10-12V regulator (CSI p/n 18529) on the mounting plate of an
environmental enclosure (see Figure 17).
2. If using deep cycle marine battery along with the SP70 solar panels,
install Battery Terminal Strip Adapters (CSI p/n 4386) to each terminal of
the user-supplied deep cycle battery as shown in Figure 18.
3. Using the supplied red and black power cables, secure the black wire to
terminal lug#1 marked battery (-) on the regulator. Connect the pigtailed
end of the black cable to the Battery Terminal Strip Adapter installed on
the battery’s negative terminal. Secure the red wire to terminal lug #2
marked battery (+) on the regulator. Connect the pigtailed end of the red
cable to the Battery Terminal Strip Adapter installed on the battery’s
positive terminal. With the battery connected and no solar panel input,
the green LED on the regulator marked CHARGING SHOULD NOT be
on.
4. Connect the black (-) wire from the SP70 power cable to terminal lug #3
marked solar (-) on the regulator. Connect the red (+) wire from the SP70
power cable to terminal lug #4 marked solar (+) on the regulator. If using
a sealed rechargeable battery, such as our BP24, then verify that the metal
jumper is installed to configure the regulator to recharge sealed
rechargeable batteries (see Figure 17). 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 17).
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 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 is shipped with
the jumper INSTALLED. If you are using flooded batteries,
such as deep cycle marine battery, REMOVE the jumper before
installing the regulator. NOTE
