6.4 Solar Panel to charge controller
Once the battery is connected to the charge controller and the panel(s) are positioned and
mounted in the desired location, we are ready to connect the panel(s) to the charge controller.
Panels should be mounted in a place that is free from shading by neighboring obstacles such as
vents, air-conditioners, TV antennas, etc.
Hazard!
The panel MUST be covered with a dark cloth to prevent the solar cells from
producing energy; this will prevent and reduce shock hazard, which can be
life threatening.
Please refer to
Figure 6.4 when completing the following connections:
1.
First, mate the “Male” MC4 Connector from the solar panel that has the negative (−)
label
with the “Female” MC4 Connector of your adapter kit as shown in
Figure 6.4 . Then
connect the bare stranded portion of the cable to the
negative (−)
solar input terminal on
the charge controller.
2.
Next, mate the “Female” MC4 connector from the panel that has the
positive (+) label
with the “Male” MC4 connector of your adapter kit as show in
Figure 6.4 .
3. The positive (+) solar cable can be fused for protection; an in-line fuse can be added to
this cable in the same way as described in the instructions for battery to controller
connection. Please refer to section
6.1 and follow the same procedure on how to add an
in-line fuse .
4.
Once the fuse holder is in place, don’t attach a fuse just yet. Connect the bare stranded
portion of the cable to the
positive (+) solar terminal on the charge controller. Ensure that
all connections are made properly, and that there are not any loose connections present.
Finally, insert the fuse into the fuse holder and remove the protective cloth. If there is
enough sunlight present, the controller will start charging the battery (ies).
5. If opting for no in-line fuse , connect the bare stranded portion of the adapter cable to the
positive (+) solar input terminal on the charge controller. Remove the protective cloth. If
there is enoug
h sunlight present, the controller’s solar LED indicator/icon on the LCD
display should show that it is now charging your battery(s).
