Harbor Freight Tools 68750 manual Cleaning, Adjustment, Operation, Servicing

Operation

Use Voltage Regulator (not included) between Solar Charger and battery to prevent overcharging battery and consequent damage.

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.

1.For charging an external battery, attach the Battery Clamp Adaptor (20) to the main Cable and connect battery clamps to battery.

NOTE: The Solar Charger must have at least four 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.

2.Set the voltage switch to either 12V to Charge a 12V battery or 24V to charge 18V and 24V batteries. See below.

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.

Servicing

Procedures not specifically explained in this manual must be performed by a qualified technician.

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.

d.Disconnect all batteries.

TO PREVENT SERIOUS INJURY FROM ELECTRIC SHOCK OR CUTS:

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.

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.

Cleaning

Clean and inspect the Briefcase Solar Charger system MONTHLY, or more frequently to maintain peak efficiency.

1.Wear electrically insulated gloves and ANSI-approved safety goggles. Dry solar panels and outdoor wiring thoroughly.

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.

6.Inspect and maintain batteries according to supplier’s instructions.

Adjustment

To increase efficiency:

1.In the Winter, increase the panel’s angle by 10°.

2.In the Summer, decrease the angle by up to 10°.

3.In the Spring and Fall, keep the panel at the angle recommended on page 4.
