Step 1: Positioning the Flexi panel(s)
1.1 Select a location that is generally free from shade, has a solid surface and is
within 3-4m of the charge controller and/or battery. If the Roof Top Kit has
been selected please also refer to Step 3.1.
1.2 If the panel is to be free standing, go to Step 2.
1.3 Ensure all panel(s) can be sited close to one another (if a multi panel
system has been selected), and that the cables can be correctly positioned.
NOTE – cables from a multi panel system will be all fed directly to the
charge controller.
bonding agent is very strong and instantly bonds, so there is only one
chance to get the location correct). Clean the area well and ensure any
(as per the pattern shown below) at about 150mm to 200mm spacing,
leaving a 70 to 100mm gap in the centre of the panel. This allows water to
exit and air to travel between the roof and panel. Apply even pressure to
the panel to compress the adhesive from 10mm to 5mm.
On a ribbed roof use the same method but apply double lines of adhesive
on the peak of each rib, leaving the rib base open.
If the panel has a rear cable exit, apply a circle (or two circles if space
permits) around the junction box to ensure the roof hole is well sealed.
Please check the manufacturer’s recommended curing time if using
another bonding agent.
NOTE
front exit panels, the MC4 connectors will need to be removed to feed the wires
through the cable gland and new MC4 connectors attached using crimping pliers
Please note
before moving the vehicle.
Do not put excessive pressure on the roof when bonding panel to surface
– a 10mm bead will be compressed to 5mm. Try to avoid pushing down
unevenly, apply gentle pressure across the panel when setting the panel
Step 2: Prepare the cable
2.1 The black outer sheath should be removed approximately 20mm and the
inner red and black cables will be revealed. Remove this sheath and the
copper cable will be visible. RED = POSITIVE (+) BLACK = NEGATIVE (-).
2.2 Connect to a charge controller by following Step 4.
Step 3: Fix the cable feed gland (only for roof top kits)
3.1 If a roof top kit containing two Flexi panels has been selected a double
gland grommet.
3.2 The cable feed gland is a completely waterproof unit designed to cover a
hole that has been drilled to channel the Flexi cable from the outside to
inside. The location of the Flexi panel(s) (as discussed in Step 1.1) will have
been determined, to a certain extent, by the desired location of the cable
feed hole. The cable entry point should allow the cable(s) to be easily
routed to the charge controller (if used) and the battery.
3.3 Now slacken the feed grommet(s) on the cable feed gland to allow the
cable to be easily threaded through it and allow the cable(s) to pass
through the drilled hole.
line of adhesive on the underside of the gland ensuring there are no gaps.
24 hours to cure. Ensure this process is completed at roughly the same
time as step 1.4.
Please read all instructions carefully before work begins.
Please refer to circuit diagram and at all times observe correct polarity; RED (BROWN) = POSITIVE (+) BLACK (BLUE) = NEGATIVE (-).
3.5 Now push the cable(s) from the solar panel(s) through the gland grommet
so that it is reasonably taught. The threaded grommet can now be
tightened ensuring a perfect seal is made around the cable itself.
Special note -
Rear exit panels have cables that exit rear of
protrusions on the top surface. This will require
a hole drilled in the roof to allow the bell cap
position to ensure weather resistance.
The shading diode box for the 110wp and 150wp
Flexi solar panels must be tted. (The shading
diode is contained within the junction boxes
for panels of 200wp and above).
Please wire as per picture.

Step 4: Connecting the Flexi cable to a charge controller (if supplied)
4.1 Position the charge controller as
close as possible to the battery
(must be a dry location).
4.2 Measure the distance between your
battery terminals and the charge
controller.
4.3 Cut the measured length of cable
(or use any DC, 2 core cable at 1mm diameter for the 10wp or 20wp Flexi
length from the Flexi panel to reach the charge controller.

Strip back 20mm of the black outer sheath of the cable end to be
connected to the charge controller.
4.5 Strip back 20mm of the black and red inner sheaths to reveal the bare
cable. Crimp the supplied ring terminals to the cable end and attach the
cable to terminals G of the charge controller, ensuring the positive and
negative polarity is observed.
4.6 Using the cut section of cable as described in Step 4.4, attach one end
to the terminals H (see image above) in the same way as described in
Step 4.5.
