5. Once proper location and angle have been reached,  
connect the Cable (15) to the input at the back of the  
power unit. The blue LED light will illuminate (flash),  
indicating the Solar Charger is generating electricity.  
Location  
1. Locate the Solar Panel where it will receive full,  
unobstructed sunlight, especially during midday.  
Nearby trees or tall plants will drop debris, requiring  
the panel to be cleaned more frequently.  
Wiring  
2. The installation location for panels, charge  
controller/regulator, and batteries must be  
inaccessible to children to prevent electric shock.  
Build a childproof enclosure if needed.  
Note: Only a licensed electrician and a licensed building  
contractor can safely design and implement a grid  
tie-in system. Any grid tie-in system must meet all  
applicable building and electrical codes, and must meet  
standards established by the area power company.  
3. Install the charge controller/regulator and batteries  
in a weatherproof enclosure with proper ventilation.  
1. Run wires from panels, through weatherproof  
grommets and into enclosure where charge  
controller/regulator is located. Use wires  
of the proper size and rating and use twist  
connectors (not included) to connect wires.  
Setup  
1. Select a mounting location for the Solar Charger.  
The Solar Panels (6,9) should face the Sun, and not  
be blocked by shadows. The location should allow  
the Panels to be protected from accidental damage.  
The location should be a flat, level surface able  
to support the weight of the Solar Charger, and  
any additional accessories. Before setup, be sure  
that the main cable to either the Battery Clamp  
Adaptor (20), the Barrel Plug Adaptor (21) or  
either of the Car Adaptors (19,22) will reach from  
the Solar Charger to the battery to be charged.  
2. Connect to charge controller/regulator according  
to controller/regulator’s instructions.  
3. Secure all connections using terminals, or solder  
all wire splices to ensure good connections.  
4. Weatherproof all connections and route the wire in  
a way that it will not be torn loose from the panel.  
2. To setup, flip open the Solar Charger. Slide the  
Support Bases (2,12) out from the Right and Left  
Housing (4,10). Set the Support Rods (3,11) against  
the Support Bases to lock the Bases in place.

d. Disconnect all batteries.  
TO PREVENT SERIOUS INJURY FROM  
Operation  
ELECTRIC SHOCK OR CUTS:  
Use Voltage Regulator (not included) between Solar  
Charger and battery to prevent overcharging battery and  
consequent damage.  
Do not use damaged solar panel.  
If wiring insulation is damaged or  
weathered, glass is cracked, or housing  
is opened, have the problem corrected  
before further use.  
The Solar Charger may also be used to maintain charge  
on batteries which are powering other items, such as a  
car radio while the car is parked.  
Note: It is normal to see up to 20% degradation in  
amorphous silicon solar panel performance within the  
first 6 months before the amorphous coating stabilizes.  
1. For charging an external battery, attach the  
Battery Clamp Adaptor (20) to the main Cable  
and connect battery clamps to battery.  
Cleaning  
NOTE: The Solar Charger must have at least four  
Clean and inspect the Briefcase Solar  
Charger system MONTHLY, or more  
frequently to maintain peak efficiency.  
hours of direct sunlight to fully charge a battery.  
WARNING! Connect Battery Clamps according  
to correct polarity (red for positive and black for  
negative.) Do not short circuit the Battery Clamp.  
1. Wear electrically insulated gloves and  
ANSI-approved safety goggles. Dry solar  
panels and outdoor wiring thoroughly.  
2. Set the voltage switch to either 12V to Charge a 12V  
battery or 24V to charge 18V and 24V batteries.  
See below.  
2. Cover all solar panels with an opaque  
cover, such as a blanket.  
3. Disconnect all solar panels and batteries.  
4. Clean solar panels one at a time with mild, non-  
abrasive cleanser and soft cloth and paper towels.  
Do not clean with brushes or abrasive cleaners.  
5. Inspect the general condition of the Briefcase Solar  
Charger system (panels, batteries, controllers,  
and mounting). Check for loose hardware,  
wiring insulation damage or weathering, cracked  
glass, open housing, cracked or broken parts,  
loose or corroded contacts, and any other  
condition that may affect its safe operation.  
CAUTION: Disconnect the Solar Charger from  
cigarette lighter or battery terminal before  
starting engine. Surges of electricity from the  
alternator may damage the Solar Panel.  
6. Inspect and maintain batteries according  
to supplier’s instructions.  
Adjustment  
To increase efficiency:  
Servicing  
1. In the Winter, increase the panel’s angle by 10°.  
2. In the Summer, decrease the angle by up to 10°.  
Procedures not specifically explained in  
this manual must be performed by a  
qualified technician.  
3. In the Spring and Fall, keep the panel at  
the angle recommended on page 4.  
TO PREVENT SERIOUS INJURY  
FROM ELECTRIC SHOCK:  
Before service, maintenance or cleaning:  
a. Dry solar panel and outdoor wiring thoroughly  
while wearing electrically insulated gloves.  
b. Cover all solar panels with an opaque  
cover, such as a blanket.  
c. Disconnect all solar panels.
