Quick Start Setup
Step 1: Verify that you have each kit component, and that your shipment is complete. Check for the following items.
 3 180-watt solar panels
 2 pairs of male/female solar connector branch connectors joined together
 a pair of 15ft solar connector extension cables(10AWG)
 a red/black 6” solar-connector-to-bare cable pair (10AWG)
 a 5-foot red/black bare-wire-to-ring-lug cable pair (charge-controller-to-battery 10AWG)
 a 5-foot red/black cable pair (battery-to-inverter 4AWG)
 a Xantrex SW2000 inverter
 3 sets of Grape Solar Zippity-Feet mounting brackets

Step 2: For optimum output, place the panels so they are fac-
ing due south at approximately the same angle as your
latitude, in full sun. If you are connecting the system dur-
ing 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 40BT controller if desired (note that it must
be in a NEMA-4 rated enclosure if it is outdoors). Open
up the input/output terminals by turning the top screws
Step 4: Attach the lug end of the red cable to the positive termi-
nal on the battery and the bare end to the Battery + input on
the charge controller. Attach the lug end of the black cable
to the negative terminal on the battery and the bare end to
the Battery - input on the charge controller.
If your battery has sufficient charge (11.5 volts or more), you
should see the LCD display activate on the 40BT. This means
the controller has power (controllers are powered by the battery,
not the panels).
Step 5: Connect the positive and negative outputs of the panel
to the appropriate T-branch connectors, as seen below.
Panels 2 and 3 connect to the 1st pair, and the outputs of
that 1st pair along with Panel 1’s outputs connect to the
second pair.

Step 5: Continued from last page.
3-panel T-branch connection
Step 6: Connect the solar connector outputs of the T-branch connect-
ors to the solar connector on 15-foot extension cables.
Step 7: Then connect the solar connector outputs of the
15-foot cables to the 6” solar connector-to-bare wire
pair as shown below:
MC4 to bare connecon
Step 8: Connect the bare wire end of the red cable to the “PV Posi-
tive” input of the 40BT, and the black cable end to the “PV
Negative” input .
Step 9: Connect the red (positive) and black (negative) 5-
foot cable from battery to inverter
Step 10: Uncover the panels. As the day progresses, you should
see the battery capacity percentage increase until the charge
controller is in float mode. At this point the battery can be
used to provide power (turn the inverter on and plug your AC
devices into it for power).
