Please read these instructions BEFORE installing or operating the solar panel to prevent
personal injury or damage to the solar panel.
WARNING!
!
CAUTION!
1. WARNING! To reduce risk of explosion, do not install in machinery space or in area in
which ignition-protected equipment is required to be used.
2. WARNING! Observe the following when working with Lead Acid Batteries.
•
Batteries contain very corrosive diluted Sulphuric Acid as electrolyte. Precautions should
be taken to prevent contact with skin, eyes or clothing. Wear eye protection.
•
Batteries generate Hydrogen and Oxygen during charging resulting in evolution of ex-
plosive 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. Always
use insulated tools.

SECTION 1 | Safety Instructions
•
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 terminal from the battery
rst. Make sure that all the accessories are off so that you do not cause a spark.
3. CAUTION! Bare bullet type of terminal on the SAE Adapters (5, in Figs 2.3 and 2.4) will
be carrying +12 VDC battery voltage when the Adapter is connected to the 12V battery.
If this bare 12V live terminal touches the Negative terminal of the battery or any metal
portion of the vehicle chassis (metal portion of vehicle chassis is connected to the battery
Negative), direct short circuiting of the battery will occur and the fuse inside the Adapt-
ers will blow. Hence, ensure that the bare bullet type of terminal remains covered and
insulated all the time with the help of the Protection Cover (6 in Figs 2.3 and 2.4). The
Protection Cover should be removed only when the SAE Connector is mated with the
SAE Connector on the solar panel wiring (4 in Figs 2.1 and 2.2).
4. CAUTION! Do not ex or bend the panel as this could cause damage to the PVC cells
and the encapsulation layers.
5. CAUTION! Do not attempt to charge non-rechargeable batteries on the battery speci-
cations. This SunCharger is meant only for 12V rechargeable Lead Acid batteries.
1. MISE EN GARDE! Pour réduire le risque d'explosion, ne pas installer dans des machines ou dans la zone
dans laquelle l'inammation, l'équipement de protection est obligatoire.
2. MISE EN GARDE! Observer les points suivants lorsque vous travaillez avec des batteries plomb-acide.
• Les batteries contiennent de très corrosif de l'acide sulfurique dilué comme électrolyte. Des précautions doivent
être prises pour empêcher tout contact avec la peau, les yeux ou les vêtements. Porter des lunettes de protection.
•
Les batteries génèrent de l'hydrogène et de l'oxygène pendant la charge, ce qui entraîne l'évolution du
mélange gazeux explosif. Des précautions doivent être prises pour ventiler la zone de la batterie et suivre
les recommandations du fabricant de la batterie.
• Ne jamais fumer ou permettre qu'une étincelle ou une amme à proximité des batteries.
• Procédez avec précaution pour réduire le risque de chute d'un outil métallique sur la batterie. Il pourrait
déclencher ou court-circuit de la batterie ou d'autres pièces électriques et pourraient provoquer une
explosion. Toujours utiliser des outils isolés.
• Retirer les objets métalliques tels que bagues, bracelets et montres lors de travaux avec des batteries. Les
batteries peuvent produire un courant de court-circuit sufsamment haut pour souder un anneau ou
similaires à metal et donc provoquer des brûlures sévères.
• Si vous avez besoin de retirer la batterie, retirez toujours la borne de masse de la batterie en premier.
S'assurer que tous les accessoires sont off an de ne pas provoquer une étincelle.
3. ATTENTION! Le type de borne à nu sur les adaptateurs SAE (5, sur les gures 2.3 et 2.4) transportera une
tension de batterie de +12 VCC lorsque l'adaptateur est connecté à la batterie 12V. Si ce terminal nu 12V
live touche la borne négative de la pile ou une partie métallique du châssis du véhicule (partie métallique
du châssis du véhicule est connecté à la borne négative de la batterie), court-circuit direct de la batterie
va se produire et le fusible à l'intérieur de l'adaptateur. Par conséquent, s'assurer que le type de terminal
bullet nu reste couvert et isolé tout le temps avec l'aide de la couvercle de protection (6 Figures 2.3 et 2.4).
Le couvercle de protection doit être retiré uniquement lorsque le connecteur SAE est accouplé avec le con-
necteur SAE sur le câblage du panneau solaire (4 Figures 2.1 et 2.2).
4. ATTENTION! Ne pas plier ou tordre le groupe car cela pourrait causer des dommages aux cellules et le PVC
l'encapsulation des couches.
5. ATTENTION! N'essayez pas de charger des piles non rechargeables sur les spécications de la batterie.
Cette SunCharger est destiné seulement pour 12V plomb-acide rechargeable batteries.

SECTION 3 | General Information
3.1 DESCRIPTION
SunChargers SC-05 and SC-10 are portable solar panels designed for oat charging of 12V
nominal rechargeable Lead Acid batteries like those used in cars, boats, RV’s, motorcycles,
All Terrain Vehicles (ATV) and Powered Water Crafts (PWC). These can also be used as DC
power sources to charge small electronic devices like cell phones, iPods, iPhones, PDAs etc.
The rechargeable batteries inside these small electronic devices are charged through their
charging adapters.
The panel oat charges the battery directly through built-in Blocking Diode (Forward Voltage
Drop, Vf= 0.55V). External Charge Controller is not necessary (see Section 5.2)
3.2 SELF DISCHARGE AND TRICKLE CHARGING OF LEAD ACID
BATTERIES UNDER STORAGE
3.2.1 Sulfation Due to Under Charging: A fully charged Lead Acid Battery comprises of
(i) Positive Plates: Lead Dioxide, (ii) Negative Plates: Sponge Lead and (iii) Electrolyte:
Mixture of 65% water and 35% Sulfuric Acid with Specic Gravity = 1.265 at 80°F. During
discharging, electro-chemical reactions lead to: (i) At Positive Plates: Conversion of Lead
Dioxide to soft Lead Sulfate crystals, (ii) At Negative Plates: Conversion of Sponge Lead to soft
Lead Sulfate crystals and (iii) In Electrolyte: Conversion of portion of Sulfuric Acid to water
leading to reduction in Specic Gravity (<1.1 for fully discharged condition). During re-
charging, electrochemical reactions are reversed leading to: (i) At Positive Plates: Conversion
of soft Lead Sulfate crystals to Lead Dioxide, (ii) At Negative Plates: Conversion of soft Lead
Sulfate crystals to Sponge Lead and (iii) In Electrolyte: Conversion of portion of water to
Sulfuric Acid leading to increase in Specic Gravity (1.265 for fully charged condition).
3.2.2 Effects of Sulfation: If Lead Acid battery remains undercharged over a long period
of time, the soft Lead Sulfate crystals of the uncharged portion will get hardened and will
be difcult to reconvert through normal charging (refer to Section 3.2.1 above regarding
charging and discharging reactions). Further, these Lead Sulfate crystals are non-conducting
and hence, introduce increased internal resistance in the battery. This increased internal
resistance introduces internal voltage drop during charging and discharging. Internal voltage
drop during charging results in overheating and undercharging and formation of more Lead
Sulfate crystals. Internal voltage drop during discharging results in overheating of the battery
and reduction in terminal voltage of the battery. Overall, this results in poor performance of
the battery.
3.2.3 Self Discharge: Self discharge of Lead Acid Battery is the electrical Ampere Hour (Ah)
capacity that is lost when the battery is not being charged and there is no load connected
to it. i.e. sits idle in storage. Self-discharge is caused by electro-chemical processes within
the battery and is equivalent to application of a small electrical load. For example, Lead Acid
battery stored at 30°C / 86°F would self-discharge at around 1% of remaining capacity every
day. Self-discharge increases with increase in temperature.
Self-discharge of the battery under long term storage will create condition equivalent to
under charging and consequently, lead to sulfation as explained at Sections 3.2.1 and 3.2.2
above. To prevent this, the battery should be “Float Charged” as explained in Section 2.2.4.

6 | SAMLEX AMERICA INC. SAMLEX AMERICA INC. | 7
SECTION 3 | General Information
3.2.4 Float Charging of Batteries under Long Term Storage: In order to prevent sulfation
due to under charging as a result of self-discharge, Lead Acid battery under long term storage
should be rst fully charged and then left under continuous charge using a suitable “Float
Charger” that will Float Charge the battery and provide low value of “Float Charge Current”
of around 0.1% of the Ah capacity of the battery to compensate for self discharge. SC-05 and
SC-10 SunCharger Solar Panels are designed to provide this “Float Charge Current" and thus,
prevent sulfation. Please refer to Section 5.2 for more details.
!CAUTION!
As explained at Section 3.3, “Float Charger” like SC-05 / SC-10 is designed to
provide low current > 0.1% of the Ah capacity of the battery to maintain a fully
charged battery under storage. This low current is designed to compensate for the
self-discharge under storage. This low value of current will NOT be able to recharge
a discharged battery. For re-charging of deeply discharged battery, a standard higher
capacity, 3 or 4 Stage Charger should be used.
!ATTENTION!
Comme expliqué à la Section 3.3, "otter" Chargeur comme SC-05 / SC-10 est conçu pour fournir un
courant faible > ; 0,1 % de la capacité de la batterie Ah pour maintenir une batterie complètement
chargée en vertu de l'entreposage. Cette faible consommation est destiné à compenser l'auto-décharge
en vertu de l'entreposage. Cette faible valeur du courant ne sera pas en mesure de recharger une bat-
terie déchargée. Pour changer l'état de la batterie complètement déchargée, une plus grande capacité
standard, 3 ou 4 Chargeur étape devrait être utilisé.
3.3 FEATURES
• Efcient Design and Superior Quality
• Efcient mono-crystalline PV cells – 24 cells in series with Open Circuit Voltage VOC
of 15.3V
• Direct oat charging - additional Charge Controller is not required. Lower VOC of
15.3V prevents over charging.
• A Blocking Diode is built-in, thus preventing current from owing back from the
battery to the solar panel in darkness. Hence, the panels can be connected directly
to the battery without using an external Blocking Diode. Forward Voltage Drop Vfof
the Blocking Diode = 0.55V.
• Top layer of clear, UV resistant Fluoropolymer material provides good light
transmission and self healing of slight abrasions.
• Sealed junction box (houses the Blocking Diode) has 10ft of UL listed, sunlight resis-
tant output cable terminated with SAE Connector. 2 Adapter Cable Sets with SAE to
Ring Terminals / 12V Accessory Plug have also been provided for convenient battery
connection.
• 12V batteries can be oat charged directly without use of a Charge Controller.
• Weatherproof - includes UV protection and protection from weather effects of
-40°C to +85°C (-40°F to +185°F).

8 | SAMLEX AMERICA INC.
SECTION 3 | General Information
• Easy Installation
• Slim-line and lightweight – No metal frame
•4 grommet nished holes in the 4 corners for xing the panel
• Output cable comes with SAE Connector. 2 Adapter Cable sets with SAE to Ring
Terminals / 12V Accessory Plug have also been provided for convenient battery
connection.
3.4 APPLICATIONS
These chargers can be used for the following:
• To oat charge fully charged 12 VDC Lead Acid batteries during long term storage
• To compensate for battery drain due to low currents drawn by small instrumentation in
vehicles. Electronics such as clocks, vehicle alarms etc add to the drain of the battery,
even when the ignition is off.
• To charge small electronic devices like cell phones, iPods, iPhones, PDAs etc. These
devices come with associated charging adapters that allow charging of their batteries
through a 12 VDC power source. These charging adapters come with a 12V Accessory
Plug for connecting to a DC power source through a 12V Power Outlet. As the Sun
Charger comes with an Adapter Cable Set with a 12V Accessory Plug, a suitable adapter
will be required to convert the 12V Accessory Plug of the SunCharger to a 12V Power
Outlet (this adapter is not provided with the SunCharger).

Fig 4.1 I-V Curves: SunChargers SC-05, SC-10
} }
When exposed to the sun and without any load connected, the solar panels will generate an
Open Circuit Voltage (Voc). As soon as a load is connected to the panel, the voltage at the load
will drop and the value of the voltage at the load will be determined by the current (I) drawn by
the load. Please note that at the Open Circuit Voltage Voc, the output current (I) is zero.

10 | SAMLEX AMERICA INC.
SECTION 4 | Principles of Operation
Electrical power (P) in Watts fed to the load = Voltage (V) X Current (I).
If the output of the panel is short circuited, the output current will be limited to the maximum
current that the panel can provide. This Short Circuit Current is designated as Isc.
The maximum power Pmp is fed to the load when the operating point is near the knee of the
curve as shown. At this operating point for maximum power output, the voltage is designated
as Vmp and the current is designated as Imp.
Please note that for the portion of the curve between Voc to Vmp, the current drops at a faster
rate. After that, the current is almost constant and equal to the Short Circuit Current Isc.
4.2 FACTORS AFFECTING VOLTAGE AND CURRENT OUTPUT OF A
SOLAR PANEL
The following factors affect the voltage and current of a solar panel:
• The output voltage is not affected very much by the light conditions - under shaded / cloudy
condition, the output voltage will not vary very much as compared to bright sunshine
• The output current is very sensitive to the intensity of light and will drop considerably
under shaded or cloudy conditions
• Variation in temperature has a sizable effect on the output voltage – a Negative Voltage
Temperature Coefcient results in increase in the voltage at lower temperature and
decrease in the voltage at higher temperature. For SC-05 and SC-10, the Voltage
Temperature Coefcient is -0.29% per C.
• Variation in temperature has negligible effect on the current output. Current Temperature
Coefcient of SC-05 and SC-10 is +0.05% per C.
• The output current can increase by 25 % due to what is known as the “Edge of the Cloud
Effect”. As the sun moves between a hole in the clouds, the solar panel will see the full
direct sunlight combined with the reected sunlight from the clouds
4.3 BATTERY CHARGING USING A SOLAR PANEL DIRECTLY CONNECTED
TO THE BATTERY
Refer to the I-V Curves of the panels at Fig 4.1.
When a battery is directly connected to the solar panel (without external Charge Controller),
the voltage of the loaded panel will be equal to the initial battery voltage. At this point, the
charging current (I) will be equal to the corresponding value of the initial battery voltage on the
I-V Curve (Fig 4.1).
The current (I) fed from the panel will start charging the battery and the battery voltage will
start rising. As the battery is always connected to the panel, the panel voltage will be the same
as the battery voltage. It will be seen from the I-V curve (Fig 4.1) that as the battery voltage
rises, the charging current will start reducing.

10 | SAMLEX AMERICA INC. SAMLEX AMERICA INC. | 11
SECTION 4 | Principles of Operation
When a battery is fully charged, it will not require any further current for charging except
the very low Float Charge Current of around 0.1% of the Ampere Hour (Ah) capacity of the
battery. If a charging current higher than the self discharge current is continued to be fed to
a fully charged battery, it will lead to damage to the battery due to overcharging resulting
in overheating and loss of water due to excessive electrolysis (conversion of water to Oxygen
and Hydrogen). In these panels, overcharging is prevented by limiting the maximum charging
voltage to around 13.8 ± 0.5V at Float Current of around 0.1% of Ah capacity of the battery.
4.4 CHARGING A BATTERY BY A SOLAR PANEL USING A CHARGE
CONTROLLER
For full scale charging of a battery from a solar panel, the output of the solar panel is required
to be fed to the battery through a Charge Controller. The Charge Controller transforms the
input power from the solar panel to regulated voltage and current necessary to safely charge
the battery as per the required charging algorithm e.g. 2/3/4 Stage Charging Algorithm.
SECTION 5 | Installation & Operation
5.1 CONNECTING CABLES
5.1.1 The panel comes with 10 ft., AWG #18 cable (3, Figs 2.1 / 2.2) with SAE Connector (4, Figs
2.1/2.2). The following Adapter Cable Sets have been provided for battery connection:
a) SAE to 12V Accessory Plug Adapter (Fig 2.3)
b) SAE to Ring Terminal Adapter (Fig 2.4)
!CAUTION!
Bare bullet type of terminal on the SAE Adapters (5 in Figs 2.3 and 2.4) will be carry-
ing +12VDC battery voltage when the Adapter is connected to the 12V battery. If this
bare 12V live terminal touches the Negative terminal of the battery or any metal por-
tion of the vehicle chassis (metal portion of vehicle chassis is connected to the battery
Negative), direct short circuiting of the battery will occur and the 10A Fuse inside
the Adapter will blow. Hence, ensure that the bare bullet type of terminal remains
covered and insulated all the time with the help of the Protection Cover (6 in Figs 2.3
and 2.4). The Protection Cover should be removed only when the SAE Connector is
mated with the SAE Connector on the solar panel wiring (4 in Figs 2.1 and 2.2).
!ATTENTION!
Bullet nu type de terminal sur l'adaptateurs SAE (5 Figures 2.3 et 2.4) fera l'alimentation +12 VCC Tension
de batterie quand l'adaptateur est connecté à la batterie de 12 V. Si ce terminal nu 12V live touche la
borne négative de la pile ou une partie métallique du châssis du véhicule (partie métallique du châssis du
véhicule est connecté à la borne négative de la batterie), court-circuit direct de la batterie va se produire et
le fusible 10A à l'intérieur de la carte va soufer. Par conséquent, s'assurer que le type de terminal bullet
nu reste couvert et isolé tout le temps avec l'aide de la couvercle de protection (6 Figures 2.3 et 2.4). Le
couvercle de protection doit être retiré uniquement lorsque le connecteur SAE est accouplé avec le con-
necteur SAE sur le câblage du panneau solaire (4 Figures 2.1 et 2.2).

SECTION 5 | Installation & Operation
5.2 CHARGING BATTERY FROM SOLAR PANEL DIRECTLY (WITHOUT
USING CHARGE CONTROLLER)
Refer to the previous Section 3.2.4. SunChargers SC-05 and SC-10 are designed to oat
charge a “fully charged” 12V Lead Acid Battery under long term storage to compensate for
self-discharge and thus, prevent sulfation due to under charging. For oat charging Lead
Acid Battery directly from a solar panel (Charge Controller is not used between the panel and
the battery), the following considerations will be applicable:
a) A 3-Stage Charger should rst be used to fully recharge the battery to be kept in
long term storage. The battery will be fully recharged when the 3-Stage Charger
enters Float Stage after completion of Bulk and Absorption Stages. Float Voltage of
12V Lead Acid Battery is normally 13.5 to 13.8VDC at 80°F / 26.7°C (Absorption and
Float Voltages will require temperature compensation based on Voltage Temperature
Coefcient of the battery which is around -24mV/°C for 12V battery). When in Float
Stage, the battery will draw a very low current equal to around 0.1% of its Ampere
Hour (Ah) Capacity at 80°F / 26.7°C to compensate for self-discharge (Self discharge
increases with increase in battery temperature).
b) The Float Voltage of 12V battery at 80°F / 26.7°C should not exceed 13.4 to 13.8V.
Higher Float Voltage will cause over-charging leading to boiling / over-heating /loss of
water / damage to the battery
c) After the battery has been fully recharged, direct Solar Trickle Charger like SunCharger
SC-05 / SC-10 should be used based on the following I-V Characteristics of the panel
(Fig 4.1):
i. The I-V Curve characteristics should be such that the panel voltage corresponding
to the Float Stage Current of the battery (0.1% of Ah capacity of the battery at
80°F / 26.7°C) should be within the range of 13.5 to 13.8 VDC to prevent over-
charging as described at (i) above.
ii. The I-V Curve Characteristic should be such that for panel voltage of 13.4 to
13.8V, the panel current should be around 0.1% of its Ampere Hour (Ah)
Capacity of the battery at 80°F / 26.7°C to compensate for self-discharge.
i
INFO
1. Specications of the panel given in Section 6 are based on the Standard Test
Condition (STC). The overall performance of the Solar Panel is dependent on a
variety of conditions including season, orientation with direct sunlight, cloudy
conditions, temperature, and shadowing. As a result, specied performance
parameters will be affected by the above operating condition.
2. For safety against excessively high short circuit current ow from the battery to a
short circuit in the cabling / panel itself, the following fuses have been provided:
• 10A Fuse in the tip of the 12V Accessory Plug provided with the SAE to 12V
Accessory Plug Adapter Cable Set (Fig 2.3)
•10A Fuse provided with SAE to Ring Terminal Adapter Cable Set (Fig 2.4)

12 | SAMLEX AMERICA INC. SAMLEX AMERICA INC. | 13
SECTION 5 | Installation & Operation
5.3 PLACEMENT OF THE PANEL
• Securely place the solar panel facing the sun. Maximum power is generated when the top
surface of the panel is oriented perpendicular to the sun. Hence, tilt the panel in such a way
that it will be perpendicular to the strong midday sun, between 10 a.m. and 2 p.m. This will
change with the seasons. In spring and in fall, a tilt between 40 and 45 degrees from the
ground will sufce for most North American locations. A little less in the summer (about 20 -
30 degrees) and a little more in the winter (about 60 - 70 degrees from the ground).
• Use the 4 grommet nished holes in the corners for xing the panel in the appropriate orientation
• Make sure that the panel is not shaded by shadows
• When using the panel in a vehicle, the panel may be placed on the dashboard and facing
the sun as explained above
5.4 FLOAT CHARGING THE VEHICLE BATTERY THROUGH VEHICLE’S
ON-BOARD 12V POWER OUTLET
When using the solar panel inside a vehicle, connect the 12V Accessory Plug provided with the
Adapter Cable Set (1, Fig 2.3) to the 12V Power Outlet in the vehicle. Make sure that the plug is
pushed in completely.
!CAUTION!
In some vehicles, the 12V Power Outlet gets connected to the vehicle’s starter battery
only when the Ignition Switch is turned to the Accessories (ACC) position. In this
case, the Ignition Switch will have to be turned to the Accessories (ACC) Position to
enable trickle charging of the battery.
Please note that when the Ignition Switch is turned to the Accessories (ACC)
position, power is available to the built-in accessories like radio, CD / DVD Player
etc. Hence, please ensure that all these accessories are switched off to prevent
