Please Read Instruction Manual before Operating

Thank you for purchasing your Nature Power Monocrystalline Solar Panel. This manual contains safety and
installation information for Nature Power Monocrystalline Solar Panels. Nature Power reserves the right to
make changes to the product, specifications and this manual without notice. Therefore, check the website for

Cautions

• Never touch the end of output cables with your bare hands when the modules are irradiated. Handle wires

with rubber-gloved hands to avoid electric shock

• Do not wear metallic jewelry when working on electrical equipment

• Product should be installed and maintained by qualified personnel

• Do not drop tools or other items on the glass of the solar module

• Do not scratch the back film of the solar panel

• Avoid exposing solar panels to partial sunlight or shadows. Partial sunlight can cause hot spots on the panel

• Do not pour chemicals on module when cleaning. To clean use a damp cloth do not apply excessive

pressure to the cells

• Do not expose solar module to sunlight concentrated with mirrors, lenses or similar means

• Keep module away from children

Precautions when working with batteries

• Never smoke or allow a spark or flame near the batteries

• 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

• Batteries contain very corrosive diluted acid as electrolyte. Precautions should be taken to prevent contact

with skin, eyes or clothing

• 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 first. Make sure that

all the accessories are off so that you do not cause a spark

• Only use rechargeable 12 Volt batteries, ie. Sealed Lead Acid, Deep Cycle, Gel-Cell etc.

• Use properly insulated tools only when making battery connections

• When working with batteries please follow the battery’s manufacturer manual and precautions

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. Do not make contact with the terminals when
the panel is exposed to sunlight or other light sources. To avoid shock hazard make sure the solar panel is
either turned over so the cells are not exposed to light or cover the cells with an opaque (dark) material such as
paper/cloth during the installation process.

Precautions when working with Charge Controllers

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. 8 Amps or 28 Amps.

Package Contents:

• 1x Solar panel with EZ connect wiring

• 4x Mounting Z-brackets

• 4x Flange Bolts

• 4x Lock Nuts

• 4x Flat Washers

• 1x Battery Clamps

Required Tools (Not Included)

• Wrench

• Hand Drill

• Pliers

• Drill Bit

Installation Overview

• Open the packaging and check to make sure that all parts have been received.

• Arrange to have on hand the proper tools to carry out the mounting installation.

• Determine the mounting location of the solar panel(s).

• Mount the charge controller within 5 feet of battery or loss of current may occur.

• Wire the battery to the charge controller and then the solar panel to the charge controller to ensure that

the correct polarity is observed.

• Secure the solar panel to the desired location, solar panel must be within 20 feet of the battery, or loss of

current may occur.

Selecting the correct Charge Controller

Charge Controllers may be sold separately and are required for installations of solar systems arrays that are
rated 12 Watts and higher. Charge Controllers help to protect the battery(s) and solar panel(s) from harmful
reverse currents, battery over charging and high wattage surges, addition protections are found on larger
charge controllers. Nature Power Products offers an 8 Amp Easy-to-Connect Charge Controller (60008) and a 28
Amp Digital PWM Charge Controller (60028). You may also choose to use a non-Nature Power charge
controller, however, please confirm that it is a 12 Volt DC charge controller. Also installations for non-Nature
Power charge controllers may not be compatible with the EZ connect cables from the monocrystalline solar
panel.
