Installation Guide

Charge Controller
Intended Use
Any solar panel that is rated 12 watts or higher requires the use of a charge controller，The Charge
controller is designed to protect your 12 Volt batteries from being overcharge and prevents discharging
of the battery overnight. Never deeply discharge your battery; never let your battery voltage pass below
11.0 volts. It will cause permanent damage to the battery. Use a DMM Digital Multi-Meter to measure
your battery's voltage.
Installing Instructions

Electrical installation
Please refer to the charge controller section.
Connecting power inverter
Please refer to the power inverter Manual.
*Power inverter is optional and may not be included.
Selecting the correct charge controller
Charge Controllers are sold separately and are required for installations of solar systems arrays that are
rated 12 Watts and higher. Nature Power Products offers charge controllers from 8Amp-32Amp. One
Charge Controller can regulate multiple solar panels.
Selecting the correct battery
Nature Power does not offer batteries. However, please choose a 12 Volt rechargeable battery. Do not
attempt to recharge non-rechargeable batteries. 6 Volt battery configurations may also be used if
connected in series (Negative to Positive). You may choose a Sealed Lead Acid battery, a Gel-Cell or a
Deep Cycle 12 Volt battery. Batteries come in all different sizes, please converse with your battery dealer
for more information on which type of battery you should use for your system. Note your solar panel
amperage rating when selecting your battery size.
Location of solar module
Please locate your solar module in a position where it can absorb direct sunlight on the solar panel, and
generally free from cover and shade. To capture the most sunlight in a day Solar Modules should be
facing 20 degrees South if you are in the Northern hemisphere and 20 degrees North if you are in the
Southern hemisphere. The Solar Module can become very hot, please keep out of reach of children. Do
not place heavy objects on Solar Module.
Out put power testing
You may use a voltage meter or a digital multi-meter to measure the voltage of your Solar Module before
connecting to the battery. Voltage can range between 15-22 volts; Testing will ensure correct charging
operation. Testing equipment not included.
Make sure your battery has enough voltage for the controller to recognize the battery type before first
installation.
The battery cable should be as short as possible to minimize loss.
The regulator is only suitable for lead acid batteries: AGM, GEL.
it is not suited for nickel metal hydride, lithium ions or other batteries.
The charge regulator is only suitable for regulating solar modules. Never connect another charging
source to the charge regulator.
