INTRODUCTION
CONGRATULATIONS ON YOUR PURCHASE OF A
SAMLEX SOLAR RV KIT!
Your new Samlex Solar RV kit provides you with a clean, green, silent and
sustainable way to ensure your batteries are fully charged and you have
a continuous source of electricity while dry camping or in the absence of
a conventional source of electricity. The Samlex Solar RV Kit comes with a
high quality solar panel, which produces DC electricity when illuminated by
sunlight. A state-of-the-art 30 Amp solar charge controller is also provided
in the kit to be connected between the solar panel and the storage
batteries. The solar charge controller will make sure the battery is charged
with the harnessed solar electricity, as per the battery manufacturer’s
recommendations. The solar charge controller comes with eight selectable
charging proles to meet the charging requirements of most standard
lead acid batteries used in RVs and remote off-grid solar applications as
well as Nickel Cadmium (NiCad) batteries. The LCD screen on the charge
controller provides detailed information about the system status including
battery voltage and charging current. The solar charge controller is
ush mountable, which is ideal for mounting within the RV interior. The
Samlex Solar RV kit also incorporates mounting hardware including sturdy
aluminum Z-brackets with the nuts and bolts required to at mount the
solar panel on the roof of the RV or any other at surface. If you wish
to optimize the collection of solar energy by tilting the solar panel to an
optimal inclination, the adjustable tilt-mount may be purchased optionally.
The cable management hardware incorporated in the kit will enable you to
effectively manage any external wiring. To expand your system further and
harness more energy from the sun, you may use one of our expansion kits
which come with a solar panel and all the hardware you need to mount the
extra solar panel and link it to the existing system.
This manual provides instructions on how to put together the various
components of the RV solar charging kit. Please refer to the separate solar
charge controller manual for detailed information about the installation,

GENERAL SAFETY
3.1. Warnings
Please read the instruction manual carefully before attempting to carry out
any installation and wiring. Contact your RV dealer or Technical support at
Samlex America (1-800-561-5885) for any questions concerning the installation.
Installation and wiring compliance
Installation and wiring must comply with the local and National Electrical Codes and must be done
by a certied electrician.
1. Disconnect all power sources before carrying out the installation.
2. Make sure the correct polarity is observed when making connections between the solar panel,
charge controller and the battery. Damage due to reverse polarity connection is not covered
by warranty.
3. Make sure all wire connections are secure as loose connections may cause sparks.
4. Wear appropriate clothing and safety gear including protective eyewear when performing
any electrical installation.
Preventing re and explosion hazards
Working with electronic/electrical equipment may produce arcs or sparks. Thus, such equipment should not
be used in areas where there are inammable materials or gases requiring ignition protected equipment.
These areas may include spaces containing gasoline powered machinery, fuel tanks, battery compartments.
Precautions when working with batteries
• Batteries contain very corrosive diluted sulphuric acid as electrolyte. Precautions should be taken
to prevent contact with skin, eyes or clothing.
• Batteries generate hydrogen and oxygen during charging resulting in evolution of explosive gas mixture.
Care should be taken to ventilate the battery area and follow the battery manufacturer’s
recommendations.
• Never smoke or allow a spark or ame near the batteries.
• Use caution to reduce the risk of dropping a metal tool on the battery. It could spark or short circuit
the battery or other electrical parts and could cause an explosion.
• Remove metal items like rings, bracelets and watches when working with batteries. The batteries can
produce a short circuit current high enough to weld a ring or the like to metal and thus cause a severe
burn.
• If you need to remove a battery, always remove the ground terminal from the battery rst. Make sure
that all the accessories are off so that you do not cause a spark.
• Use properly insulated tools only when making battery connections.
Precautions when working with solar panels
With the incidence of sunlight or other light sources on all solar panels, a voltage appears at the output
terminals of the solar panel turning it into a source of electricity. To avoid a shock hazard make sure the solar
panel is covered with an opaque (dark) material such as paper/cloth during the installation. Do not make
contact with the terminals when the panel is exposed to sunlight or any other light sources.

GENERAL SAFETY
Precautions when working with Charge Controller Model no. SCC-30AB
If two or more solar panels are connected in series/parallel make sure that the sum of the short circuit current
ratings of all panel strings does not exceed 80% of the charge controller’s current rating i.e. 24 Amps for the
30 Amp charge controller. The open circuit voltage of the solar array i.e. the maximum voltage across the array
should not exceed 26 V when the 12 V setting on the charge controller is used and not exceed 52 V when the
24 V setting on the charge controller is used.
3.2. Routine Maintenance
• Inspect the solar panels and make sure the surface is free from dust, dirt and other debris,
clean with a wet cloth or glass cleaner, if necessary.
• Check to make sure all structural components, mechanical fasteners and electrical connections are
secure, clean and corrosion-free.
• Check and maintain the battery electrolyte levels at regular intervals as per the battery manufacturer’s
recommendations if ooded wet cell lead acid batteries are used.
• Check and replace damaged components if necessary.
3.3. Installation Overview
1. Read the manual in detail and understand the installation procedure.
2. Open the packaging and check to make sure that all parts have been received as per the parts list
in the manual.
3. Arrange for the required tools to carry out the installation. A sample list of tools (not exhaustive)
is provided in Section 4.
4. Determine the mounting location of the solar panel(s) on the roof of the RV.
5. Mount the charge controller at the desired location (see Section 5).
6. Pass the cable from the solar panels to the interior of the RV (See section 6).
7. Wire the battery to the charge controller and then the solar panel to the charge controller ensuring
the correct polarity is observed (See Section 6).
8. Secure the solar panel to the RV roof (See Section 7).

any standard lubricant will minimize the occurrence of
“thread galling”.
3. If wiring distances are longer than the lengths of wire
provided with the kit, extra stranded copper wire will
be required. Wires should be 12 AWG or thicker, single
conductor, Type UF (Underground Feeder - marked as
sunlight resistant), Type SE (Service Entrance) or Type USE/
USE-2 (Underground Service Entrance).
4.1. Required Tools
1. The Samlex Solar RV kit comes with a 30 Amp PWM charge controller Model no. SCC-30AB to optimally
charge your batteries from the solar panel.
2. The Solar charge controller comes with its own detailed manual. Read the manual in detail.
The instructions in this section are only a brief summary of information contained in the manual.
3. Make sure the solar panels and batteries are disconnected from the charge controller before
installing the charge controller.
4. The charge controller should ideally be located in an area relatively close to the battery.
5. The charge controller should be mounted indoors in a dry location.
6. The charge controller is designed to be ush mounted on a wall or cabinet so that the wiring
at the back can be accessed. Allow adequate spacing (2-3 inches) behind the unit to accommodate
the charge controller and the wiring.
7. Using the cut-out template provided in the charge controller manual, mark the cut-out on
the installation surface and the location of the mounting holes.
8. Using a hand drill and suitable drill bit, drill the mounting holes.
9. Using a jig saw or suitable cutting tool cut the material out from the installation surface.
10.After wiring the charge controller terminals (see Section 6 on wiring), x the mounting plate

WIRING
The battery must be wired to the charge controller before the solar panel is connected to the charge controller.
A pair of 20 foot pre-assembled cables with Multi-Contact (MC) male and female connectors is provided
primarily to connect the solar panel to the charge controller. After making sure that sufcient length is
available to wire the solar panel to the charge controller, any excess wire maybe used to wire the battery to the
charge controller.
6.1. Battery to Charge Controller
• Mark the cables to differentiate between Positive and Negative.
• Make sure the Positive terminal (marked ‘+’) of the battery is connected to the Positive terminal (marked
“BAT +”) of the charge controller and the negative terminal (marked ‘-’) of the battery is connected to
the Negative terminal (marked “BAT -”) of the Charge Controller SCC-30AB. If you are not sure use a DC
voltmeter to determine the polarity of the battery bank. Reverse polarity connection will damage the
Charge Controller and the resulting damage will not be covered by warranty.
• Crimp the insulated fork terminals provided (Fig 6.1.3) to one end of the Positive and Negative battery
leads.
• Insert the fork terminals (g 6.1.3) into the appropriate terminal on the charge controller: Positive lead is
connected to the Positive terminal (marked “BAT+”) of the charge controller Negative lead is connected
to the Negative terminal (marked “BAT -”) of the Charge Controller SCC-30AB.
• Crimp the battery ring terminals (g 6.1.2) provided to the Positive and Negative wire leads to be
connected to the battery terminals.
• Clean the battery post terminals free of corrosion and other impurities.
• Bolt the ring terminals to the battery terminals making sure the correct polarity is observed.
6.2. Solar Panel to Charge Controller
1. Determine the position of the solar panel on the RV roof. While positioning panels, avoid shading of the
solar panel by neighbouring obstacles such as vents, air-conditioners, TV antennas etc. As far as possible,
position the panels to minimize wiring distance between the solar panel and the charge controller. Place
the panel at least 8-10 inches away from the RV roof edges and leave sufcient space to walk around the
panel and access the mounting hardware.
2. Make sure the thickness of the roof at the installation location is at least ½” thick and the material
is strong enough to provide mechanical support to the solar panel and mounting hardware against
possible wind loading. Place the panel length-wise to reduce the effects of wind loading on the RV.

WIRING
3. The solar panels come with a sealed pre-wired junction box with both positive and negative leads
having male and female Multi-contact (MC) connectors respectively. The polarity of the conductors is
marked as ‘+’ for the positive lead and ‘-’ for the negative lead. Do not connect the male and female MC
connectors from the same solar panel together as this will short the solar panel.
4. Connect the MC connector corresponding to the positive lead (marked as ‘+’) on the solar panel to the
suitable mating MC connector from the cable pair provided.It is advisable to identify this extension cable
as the positive lead using a sticker.Similarly connect the MC connector corresponding to the negative
lead (marked as ‘-’) to the suitable mating MC connector from the cable pair provided. As before,
identify this extension cable as the negative lead using a sticker.
5. The cable pair from the solar panel can be routed to the interior of the RV through the roof-top
refrigerator vent. Find where the refrigerator vent is located on the roof of the RV.
6. Select a suitable mounting location for the solar panel, preferably as close to the vent as possible. The
mounting surface should be strong enough to support the mounting hardware, the solar panel and
wind loads.
7. Take off the vent cover to gain access to the duct opening and keep the vent fastening hardware safely
as the vent cover will have to be replaced after the wire has been routed.
8. The wire from the solar panel can be routed by either:
A. Hole in the side of the vent: Drill a suitable hole in the side of the vent and insert a rubber grommet (not provided). Route the
cable pair carefully to the charge controller through the hole. Use appropriate sealant as recommended by your local RV dealer
to ensure the penetration at the side of the vent is watertight.
B. Through the vent screen: Route the cable pair through the vent screen grid holes. Widen the screen grid holes if necessary.
9. Use the cable clamps with #8 self-tapping screws and tie wraps at regular intervals of the wire route
from the solar panel to the charge controller to hold the cables in place for a neat nish. Tuck any excess
wire under the refrigerator vent cover.
10.Replace the refrigerator vent cover and secure with the retained hardware.
11.Crimp the bare end of the cables with the fork terminals provided.
12.Insert the terminals into the appropriate terminal on the charge controller: positive PV lead is connected
to the positive terminal (marked “PV +”) of the charge controller and the negative PV lead is connected
to the negative terminal (marked “PV -”) of the charge controller. Reverse polarity connection will
damage the Charge Controller and the resulting damage will not be covered by warranty.

SOLAR PANEL INSTALLATION
1. Stainless steel can be subject to a process called “thread
galling” in which bolts can twist off and/or the bolt
threads seize to the nut’s thread. Apply Anti-galling
lubricant available at most hardware or auto-parts stores
to all the stainless steel fasteners before installation.
If anti-galling lubricant is not available, any standard
lubricant will minimize the occurrence of “thread
galling”.
2. Fix the mounting brackets to the frame of the previously
positioned solar panel using the slotted opening and the
¼”-20 x ¾"Flange Bolt, Nylon Locknut and at washer.
3. Using a 7/16” wrench, tighten the nuts to secure the
mounting brackets to the PV panel. Recommended
tightening torque is 15 lbs.
4. Position the panel with the attached mounting brackets
at the desired location on the RV roof and mark the
position of the desired mounting hole using a suitable
marker by tracing the hole on the mounting bracket.
Please ensure that the mounting surface on the RV roof is
strong enough to support the mounting hardware, solar
panel and wind loads.
5. The centre and end holes on the mounting brackets are
sized to accept the ¼” hardware supplied with the unit. If
the use of larger sized hardware is desired, holes 2 and 4
can be used.
Well Nut for anchoring Solar Panel to RV Roof
6. A Well-Nut is a bushing of tough neoprene rubber with
a ange at the top end and a captive brass nut mounted
within the bore at the bottom end (g. 7.3). Tightening a
conventional machine bolt or screw engages the captive
nut thereby causing the bushing to expand outwards.
This fastens securely to thinner RV roofs by bulging up
and against the bottom surface of the roof (g. 7.6). If
used in a blind hole in a solid surface material, the rubber
will expand outwards to create a secure fastening (g.
7.7). The neoprene and brass resist most environmental
conditions. Additionally, the Well-Nut seals the drilled
hole effectively against air and liquid leakage.

SOLAR PANEL INSTALLATION
7. To install the Well-Nuts, drill holes 1¼” deep at the marked positions using a ½” size drill bit. Make sure
that drilling does not interfere with pre-existing wiring installations.
8. Apply silicone or any appropriate sealant recommended by your RV dealer generously to the drilled
holes for water-proong.
9. Insert the ¼” Well-Nut into the drilled holes so that only the ange section remains above the roof
surface.
10.Fasten the mounting brackets to the roof surface by inserting the ¼ x1¼” serrated ange bolt into the
Well-Nut. Tighten using a3/8” wrench to a recommended torque of 15 lbs. When the serrated ange
bolt is screwed into the Well-Nut, the material surrounding the well nut bulges slightly securing the
structure to the RV roof.
11.Make sure all bolts and mounting brackets are covered by good amounts of suitable RV sealant
recommended by your local RV dealer.

CAUTION!
When 2 or more batteries / battery strings are connected in parallel and are then connected to
the Solar Charge Controller SCC30-AB (See Figs. 9.2 and 9.3. given above), attention should be
paid to the manner in which the solar charge controller is connected to the battery bank. Please
ensure that if the positive output cable of the solar charge controller (Cable “A”) is connected
to the positive battery post of the rst battery (Battery 1 in Fig. 9.2.) or to the positive battery
post of the rst battery string (Battery 1 of String 1 in Fig. 9.3.), then the Negative output cable
of the Solar Charge Controller SCC30-AB (Cable “B”) should be connected to the Negative battery post of the last
battery (Battery 2 as in Fig. 9.2) or to the Negative Post of the last battery string (Battery 4 of Battery String 2 as
in Fig. 9.3.). This connection ensures the following:
• The resistances of the interconnecting cables will be balanced.
• All the individual batteries / battery strings will see the same series resistance.
• All the individual batteries will charge at the same charging current and thus,
will be charged to the same state at the same time.
• None of the batteries will see an overcharge condition.
If the positive output cable of the battery charger (Cable “A”) is connected to the positive battery post of the rst
battery (Battery 1 in Fig. 9.2.) or to the positive battery post of the rst battery string (Battery 1 of String 1 in Fig.
9.3.), and the Negative output cable of the battery charger (Cable “B”) is connected to the Negative battery post
of the rst battery (Battery 1 as in Fig. 9.2.) or to the Negative Post of the rst battery string (Battery 1 of Battery
String 1 as in Fig. 9.3.), the following abnormal conditions will result:
• The resistances of the connecting cables will not be balanced.
• The individual batteries will see different series resistances.
• All the individual batteries will be charged at different charging current and thus,
will reach fully charged state at different times.
• The battery with lower series resistance will take shorter time to charge as compared to the battery
which sees higher series resistance and hence, will experience over charging and its life will be reduced.
Figure 9.3. above shows a series – parallel connection consisting of four 6 V, 200 AH batteries to form a 12 V,
400 AH battery bank. Two 6 V, 200 AH batteries, Batteries 1 and 2 are connected in series to form a 12 V, 200
AH battery (String 1). Similarly, two 6 V, 200 AH batteries, Batteries 3 and 4 are connected in series to form a 12
V, 200 AH battery (String 2). These two 12 V, 200 AH Strings 1 and 2 are connected in parallel to form a 12 V,
400 AH bank.
