First, unpack all items off pallet with housing & batteries.
BE CAREFUL WHEN MAKING CONNECTIONS TO NOT SPARK
LOOSE CABLES TO BATTERY CONNECTIONS
TOOLS
You’ll need a #3 Phillips screwdriver
and a socket 1/2” & 7/16” socket & socket wrench,
& a wire stripper crimper.
socket 1/2” & socket wrench
Take off the top 2, and 1 front sections of the housing, leaving the battey
compartment open and place your batteries with the positive + to the
front as shown.
Connect the series (middle/thick 2O, with terminal boots) cable, connecting the red to the right battery positive, and black to the opposite (left)
battery’s negative - terminal.
Controller to batteries:
#3 Phillips screwdriver
Connect the positive stripped end of the red
fused charge controller (10AWG, thinner)
wire to (middle) battery input on the SunSaver20 charge controller and screw tight,
and drop the round lug end into the hole
directly below the SunSaver20 Charge controller. Take the black stripped end (10AWG)
charge controller to battery wire and connect
it to the SunSaver20’s negative battery connection and screw tight, and drop the lug end
down the hole directly below the Sunsaver20.
Inverter to batteries:
Next, take the inverter’s red positive +, fused
(4 AWG) cable/wire, and drop it (including
fuse) down in the hole directly above the
fuse. Take the inverter’s black wire/cable an
stick it down the hole directly below the inverter.

battery’s positive+ terminal.
Connect BOTH black (inverter and charge

battery’s negative- terminal.

Locate Install location:
Find your best location to mount your Solar PV
panels. Usually facing south or southwest,
where the least amount of shade occurs year
round.
You have enough cable to go up to 25 ft
from battery/inverter housing.
Mounting Rack:
1/2” & 7/16” socket & socket wrench
Carefully, lay down the panels glass down on
a tarp or on thick debris-free grass with the
long ends flush, and where you want the PV
panels junction boxes to be. (usually same
side).
Then lay down the longest rails in about a foot
from the short dimension of the panel, or perpendicular to where the panels meet the long
way. Connect the panels and rails together
with the provided (7/16”) nuts & bolts. Face
the bolts up, so the nuts are on the rail, not the
panel. (See >)
Connect the feet (small “L” shaped) pieces to
the bottoms of all 4 rails with the 1/2” nuts &
bolts. (leave somewhat loose until you get to
install location)
Connect the shorter rails anywhere along the
rails that holds together both panels with the
provided 1/2” nuts & bolts.
This longer rail
connects both
PV modules
There are four foot pieces, that
bolt to the bottom of all four rails
This shorter rail connects to the longer
rail with a single bolt along the longer rail,
depending on the angle you desire.

Carefully, move to desired install location
and mount.
Parallel Solar Panel Interconnects:
Connect both positive + PV cables (as marked on the
junction box) and connect them both to the included “Y”
connector on the dual end or top of the “Y”.
Connect both negative - PV cables and connect both to
the included “Y” connector on the dual end or top of the
“Y”.

Solar Panels to Charge Control:
#3 Phillips screwdriver, stripper/crimper
Cut the provided PV cabling in half, and splice 1/2” or
about 2 cm off the ends opposite the MC4 connectors.
Use the fuse on the positive + PV that comes off the
panel “Y” connector. NOTE: If you need more cable for a
greater distance, use at least 10AWG wire and splice
additional 10AWG wire to PV Cable.
Load is where you could hook up
12V DC Electronics or lighting
Next connect the positive +, fused (opposite end of fuse)
to the positive bottom/single of the positive “Y” connector,
repeat the process with the negative PV cables.
(recommend coming through the small side vents)
Next, connect the positive/ stripped/ fused end from the
PV cable to the positive on the far left terminal of the
charge controller and screw tight. Finally, connect the
negative PV cable to the (2nd to far left) and screw tight.

Down to batteries
That green “charging” light means you’re making green power!
Place inverter cover on top and battery cover
on front, and you’re done!
If junction boxes are on opposite side, +
or— may be reversed. Picture depicts,
looking at backside of panel, with the PV
junction boxes on the left.
