Step 2: If you are connecting the system during daylight, cover the panel
with cardboard, cloth, or a similar option so that it does not output
power. Place the panel so it is facing due south at approximately the
same angle as your latitude, in full sun.
Step 3: Mount the controller if desired (note that it must be in a NEMA-4
rated enclosure if it is outdoors). Use the 5-foot red & black cable
pair to connect your positive and negative battery terminals to the
battery inputs on the charge controller.
Step 4: Attach the lug end of the red cable to the positive terminal on the
battery. Attach the lug end of the black cable to the negative terminal
on the battery. If your battery has sufficient charge (11.5 volts or
more), you should now see the LCD display light up on the controller.
This means the controller has power (controllers are powered by the
battery, not the panels).
Step 8: Uncover the panel. As the day progresses, you should see the battery charge percentage increase until it is reading 100%. Once
the battery is fully charged, you can use it to provide power through an inverter or through the load control output of the PWM-165.

Step 5: Connect the positive and negative outputs of the panels to the appropri-
ate T-branch connectors, as seen below. Panels 2 and 3 connect to the 1
st
pair,
and the outputs of that 1
st
pair along with Panel 1’s outputs connect to the sec-
ond pair.
Step 7: Connect the MC4 outputs of the T-branch connectors to the MC4 ends
of the cut 15-foot cable (we recommend marking the bare wire positive end with
tape, to differentiate the leads). Then connect the bare wire ends to the control-
ler.
Step 6: Cut the 15-foot MC4 cable in half and strip back the cut ends to allow
around 1/4” of bare wire, as per the photos to the right.
