GENERAL SAFETY
Warnings
Please read the Owner's 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 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 Fire 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, etc.
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 terminals or other electrical parts and could cause an explosion.
• Remove metal items like rings, bracelets and watches when working with batteries. 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 Negative terminal from the battery rst.
When connecting the battery, connect the Ground last. Make sure that all the accessories are off so that
you do not cause a spark.
• Use properly insulated tools when making battery connections.
Precautions When Working With Solar Panels
With the incidence of sunlight or other light sources on 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 installation. Do not make contact with the
terminals when the panel is exposed to sunlight or any other light sources.

CONNECTOR SYSTEM FOR CONNECTING SOLAR PANELS
The Positive and Negative outputs of the solar panel are fed through a water tight Junction Box. Appropriate
size of wires are connected to the Junction Box for further connections.The solar panels supplied with these
kits are provided with approximately 3 ft. each of Positive & Negative wires that are pre-connected to the
Junction Box. The free ends of the wires are terminated with special mating type of connectors for ease of
extending these wires for further connections. The special mating type of connectors used for the 3 ft. wires
provided with the solar panels and also for the separate extension wires are as follows:
• "SolarLine - MC4" Series manufactured by Multi Contact or compatible
General Information on MC4 Connector System
MC4 Connector System consists of male and female connectors. This type of connector system is easy to
install and uses “snap-in” type of safety locking clips to lock the two mating connectors, thereby, avoiding
unintentional disconnection. Also, the mating contacts are sealed against ingress of dust and water.
Specications are as follows:
• Contact diameter Ø 4 mm
• Maximum rated current - 30A
• Maximum system voltage - 1000 V
• Degree of ingress protection when connected and properly locked - IP67
• Temperature range 40°C to +90°C
MC4 Connectors (Figs 3.1, 3.2)
The MC4 Connectors mentioned in this manual have been designated “Male” and “Female” based on the
characteristics of the mating contact inserts inside the terminals.
In the MC4 Male Connector (Fig. 3.1), the internal mating contact insert (1, Fig. 3.1) is a male pin. It has two
slots (2 of Fig. 3.1) for insertion of the two “snap-in” type of locking tabs (5 of Fig. 3.2) of the MC4 Female
Connector (Fig. 3.2) for rm mating connection. This connector is marked "-".
In MC4 Female Connector (Fig. 3.2), the internal mating contact insert (4 of Fig. 3.2) is a female cylindrical
socket. It has two “snap-in” type of locking tabs (5 of Fig. 3.2) that are inserted into the two slots (2 of
Fig. 3.2) in the MC4 Male Connector (Fig. 3.1) for rm mating connection. Wire is crimped to the contact inserts
(1 and 4 of Fig. 3.2) using a special purpose crimping tool designed for MC4 connectors. After the wire has
been crimped, the contact insert is required to be seated securely inside the housing and the strain relief / seal
(3 of Fig. 3.1 & 3.2) is to be tightened fully to provide a water-tight seal.

CONNECTOR SYSTEM FOR CONNECTING SOLAR PANELS
Output Wires and Connections on the Solar Panel
Fig. 3.3 shows the output wires and connections on the solar panel. The output wires from the junction box of
the solar panel are terminated with the help of MC4 connectors. The Positive (+) wire is terminated with a MC4
Female Connector (marked "+") and the Negative wire is terminated with a MC4 Male Connector (marked "-").
Warning!
When the surface of the solar panel / array is exposed to sunlight, a DC voltage appears
at the output terminals turning it into a live voltage source. For example, a 24 V nominal solar
panel my put out an open circuit voltage of around 45 VDC that may produce electrical shock.
Multiple solar panels connected in series (to increase the output voltage) will put out higher
lethal voltages To avoid any electrical shock hazard during installation, make sure that the solar
panel / array is covered with an opaque (dark) material to block solar irradiation.

CHARGE CONTROLLER INSTALLATION
Required Materials
1. Silicone or any suitable roof sealant. Contact your local RV
dealer or RV store for a recommendation on a sealant to suit
your specic RV roof material.
2. Anti-galling lubricant to prevent “thread galling” of all
stainless steel fasteners exposed to outdoor environment. This
should be available at most hardware or auto-parts stores. If
anti-galling lubricant is not available, any standard lubricant
will minimize the occurrence of “thread galling”.
3. If wiring distances are longer than 20 ft. length 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). Alternatively, the following may be ordered
for additional 20 ft. extension:
• Solar Panel Connecting WIres Kit "SCW-20-2"
• Solar Panel Multi Contact Connectors "MC4-2"
Required Tools
The output from the panel is fed to the selected Solar Charge Controller (not supplied with this kit). Please
refer to Installation Instructions provided with the selected Solar Charge Controller. Minimum recommended
Charge Controller capacity is as follows:
- Single 100W Panel – 8 Amps
- Single 150W Panel – 10 Amps
1. Philips drive screw driver
2. 7/16” wrench
3. 3/8” wrench
4. Wire Stripper
5. Wire Crimping Tool
6. Hand Drill
7. ½” drill bit
8. Jig-saw or suitable cutting tool
9. Pliers
10.Punch or Awl

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 (Fig. 7.2) 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 (Fig. 7.1).
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 (Fig.
7.2) are sized to accept the ¼” hardware supplied with
the unit. If the use of larger sized hardware is desired,
3/8" holes 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 (Fig. 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 (Fig. 7.6). If
used in a blind hole in a solid surface material, the rubber
will expand outwards to create a secure fastening (Fig.
7.7). The Neoprene and brass resist most environmental
conditions.

SOLAR PANEL INSTALLATION
Typical Installation of a Well-Nut
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 (Fig. 7.4).
10.Fasten the mounting brackets to the roof surface by inserting the ¼ x 1¼” serrated ange bolt into the
Well-Nut (Fig. 7.5). Tighten using a 3/8” 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 (Fig. 7.6 & 7.8).
11.Make sure all bolts and mounting brackets are covered by good amounts of suitable RV sealant
recommended by your local RV dealer.

WIRING
Typical wiring using a single 150W/100W panel to charge 12V battery is considered and shown in Fig. 8.1.
Minimum recommended Charge Controller capacity is as follows: Single 100W Panel – 8 Amps; Single 150W
Panel – 10 Amps. NOTE: Wiring and Fuse sizes recommended below are based on use of a single 100/150W
solar panel with maximum current handling capacity of 10A.
A pair of 20 foot, AWG#12, pre-assembled cables with Multi-Contact (MC4) Male and Female Connectors
is provided 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 may be used to wire the battery to
the Charge Controller. Please refer to wiring layout at Fig. 8.1 below.
Wiring from Battery to Charge Controller
• Use AWG#12 for up to 6 ft. and AWG#10 for up to 10 ft. to limit voltage drop to 2% at maximum 10A.
• 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 (Fig. 8.1). If you are not sure, use a DC
voltmeter to determine the polarity of the battery bank. Reverse polarity connection may damage the
Charge Controller and the resulting damage will not be covered by warranty.
• 2 pieces of Ring Terminals (Fig 8.2) have been provided for crimping on the wire ends on the
battery side.
• Use Inline ATC style Fuse Holder of 10A ATC-10 fuse on the battery end of the Positive cable (Fig 8.1; NOT
SUPPLIED). The Fuse Holder comes with 4", AWG#12 pigtails. Splice one pigtail to the Positive wire end
and use the other pigtail for battery connection.
Caution!
1. The battery must be wired to the Charge Controller before the solar panel is
connected to the Charge Controller.
2. Use appropriate size of fuse in battery Positive Cable to protect against re hazard
due to short circuit in the battery cables.

WIRING
Wiring From 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.

5. The wire 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. See Fig. 8.5.
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 wires have been routed.
8. The wires from the solar panel can be routed by either of the two following methods:
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 wire 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 wire 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.
Warning:
Avoid sharp, heated or abrasive material on the cable route.
10.Replace the refrigerator vent cover and secure with the retained hardware.
11.Crimp the bare end of the wires with the fork terminals provided (Fig 8.3).
12.Insert the terminals into the appropriate terminal on the Charge Controller (Fig 8.1): 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 may damage the Charge Controller and the resulting damage will not be covered by
warranty.

Fig. 9.1: Series Connection
When two or more batteries are connected in series, their voltages add up but their Ah capacity remains the
same. Fig. 9.1 above shows 2 pieces of 6V, 200 Ah batteries connected in series to form a battery bank of 12V
with a capacity of 200 Ah. The Positive terminal of Battery 1 becomes the Positive terminal of the 12V bank.
The Negative terminal of Battery 1 is connected to the Positive terminal of Battery 2. The Negative terminal of
Battery 2 becomes the Negative terminal of the 12V battery bank.

Fig. 9.2: Parallel Connection
When two or more batteries are connected in parallel, their voltage remains the same but their Ah capacities
add up. Fig. 9.2 shows 4 pieces of 12V, 100 Ah batteries connected in parallel to form a battery bank of
12V with a capacity of 400 Ah. The four Positive terminals of Batteries 1 to 4 are paralleled (connected
together) and this common Positive connection becomes the Positive terminal of the 12V bank. Similarly, the
four Negative terminals of Batteries 1 to 4 are paralleled (connected together) and this common Negative
connection becomes the Negative terminal of the 12V battery bank.

Fig. 9.3: Series-Parallel Connection
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.
!CAUTION!
When 2 or more batteries / battery strings are connected in parallel and are then connected to the Solar
Charge Controller (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 (Cable “B”) should be connected to the Negative battery
post of the last battery (Battery 4 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 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), 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.
