Solar panels of 30W and above must be connected to an outboard regulator which, in turn, then connects
to the battery to enable battery charging. Nice offers a regulator (P/N SG-4) for this purpose. For regulators
sourced elsewhere, follow the manufacturers instructions when installing. Install and wire the 30W and above
solar panels and SG-4 regulator as follows:
1. Assemble solar panel mounting bracket and panel with included hardware.
2. Locate solar panel out of shadows of surrounding buildings, walls, etc. and orient to collect the maximum
sunlight energy throughout the year.
In the northern hemisphere, mount panels at upward angle of
about 45 degrees with panel oriented south. In the southern hemisphere orient the panel to face north.
3. Drill two holes into a vertical surface in the CBOX chassis matching the two mounting tabs on the
regulator. Mount the SG-4 with appropriate hardware to fix it in place.
4. Connect the red wire of solar panel to the yellow wire of the regulator and the black wire of solar panel
to either of the regulator’s black wires (see IMAGE 14B-1).
5. Connect the red (positive) battery wire (see notes above) to the red wire of the battery regulator and
the black battery wire (negative) to the other black wire on the regulator, then attach both battery lugs
to the battery (red to positive and black to negative). See IMAGE 14B-1).
NOTES:
• Wire-to-wire connections may be made using wire nuts, crimp caps, or butt connectors, as long as the
connections are secure
.
• It is permissible to cut off 8” to 10” (or so) of the solar panel wires (with battery lugs) in order to use
for attaching the regulator to the battery.
• The SG-4 prevents reverse current leakage at night, so a blocking diode is not required in the system.
• A negative earth ground at the battery is recommended for most effective lightning protection.
•
The SG-4 can be mounted outdoors, but do not expose to ambient temperatures above 140˚F (60˚C).
• Ensure that water is able drain from inside the case if it becomes wet.
