4Connect the solar panels  together into a
three-panel series “string”. Series connections
are made when the positive cable from one
panel is connected to the negative cable from
the next panel. On the open positive end of the
triad, connect a 20-amp in-line fuse .
Attach the bare-wire ends of the MC4-to-Bare Wire
pair  to the charge controller . The red wire con-
nects to the (+) input and the black wire connects to
the (-) input.

Mount the solar panels  so that they are facing due South at approximately the same angle as your latitude.
The ideal area has full sun and no shading. If the following connections are made during daylight, cover the
panels with cardboard, cloth, or a similar opaque material so that the panel does not output power.
Connect the bare wire end of the 10 AWG (thinner) red battery cable
 to the (+) battery terminal on the bottom of the charge controller
. Connect the bare wire end of the 10 AWG (thinner) black cable 
to the (-) battery terminal. A Phillips head screwdriver can be used
to loosen and tighten the screw clamps onto the wires.
Attach the ring lug end of the red cable  to the positive terminal of a
12V deep cycle battery. Attach the ring lug end of the black cable 
to the negative terminal of the battery.
The charge controller  display screen will be visible if the battery
has sufficient charge. If the display screen is not visible, the battery
must be charged from an another source before processing solar
power. The charge controller, which regulates solar power flow to the
battery, is powered by the battery.

Use the 15-ft MC4 cables  to connect the solar panel  triad to a Zenith-40 charge controller .
Ensure that the positive and negative cable from the solar panel triad are connected to respective
input sockets on the controller. If the batteries are not full, you should begin to see power flowing into
the batteries.
