Important Safety Instructions
Please save these instructions.
Please read the instruction manual carefully before attempting to carry out any installation
or wiring. Contact Technical support for any questions concerning the installation.
WARNING: Indicates a potentially dangerous condition. Use extreme caution when
performing this task.
CAUTION: Indicates a critical procedure for safe and proper operation.
NOTE: Indicates a procedure or function that is important to the safe and proper operation.
Installation and wiring compliance
Installation and wiring must comply with the local and National Electrical Codes and must be done
by a certified electrician. Please follow these four steps:
1. Read all of the instructions and cautions in the manual before beginning the installation.
2. It is HIGHLY recommended to install a charge controller in order to charge your batteries.
It is dangerous for unregulated panels to be connected to battery banks.
3. Make sure all wire connections are secured; loose connections may cause sparks.
4. Wear appropriate clothing and safety gear including protective eyewear when performing
any electrical installation.
Preventing fire and explosion hazards
Working with electronic/electrical equipment may produce arcs or sparks. Thus, such equipment
should not be used in areas where there are flammable materials or gases requiring ignition
protected equipment. These areas may include spaces containing gasoline-powered machinery,
fuel tanks, and battery compartments.
Precautions when working with batteries
Batteries contain very corrosive diluted sulfuric acid as electrolyte. Precautions should be
taken to prevent contact with skin, eyes, or clothing.
Batteries generate hydrogen and oxygen during charging, resulting in the evolution of an
explosive gas mixture.

3
Care should be taken to ventilate the battery area and follow the battery manufacturer’s
recommendations. Never smoke or allow a spark or flame 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.
Remove metal items such as rings, bracelets, and watches when working with batteries.
The batteries can produce a short circuit current high enough to weld a ring or similar
object to the metal, causing 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 properly insulated tools when making battery connections.
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. To avoid a shock hazard,
make sure the solar panel is covered with an opaque (dark) material such as paper or cloth during
the installation. Do not make contact with the terminals when the panel is exposed to sunlight or
any other light source.
Precautions when working with charge controllers
If two or more solar panels are connected in a 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. 24A for the 30A charge controller). The open circuit voltage of the solar array (i.e. the
maximum voltage across the array) should not exceed 26V when the 12V setting on the charge
controller is used, and may not exceed 52V when the 24V setting on the charge controller is used.
Routine maintenance
Inspect the solar panels and make sure the surfaces are free from dust, dirt, and other
debris; clean with a wet cloth or glass cleaner if necessary.
Check to make sure all structural components, mechanical fasteners, and electrical
connections are secure, clean, and corrosion-free.
Check and maintain the battery electrolyte levels at regular intervals as per the battery
manufacturer’s recommendations if flooded wet cell lead acid batteries are used.
Check and replace damaged components if necessary.

General Information
A new RENOGY Off-Grid Solar Kit will provide you with a clean, silent, and sustainable
way of ensuring that batteries are fully charged and capable of providing a continuous supply of
electricity. Each kit comes equipped with a high quality solar panel that features highly efficient
silicon solar cells. If you have purchased a RENOGY Off-Grid Solar Kit, a PWM Solar Charge
Controller is also included in the package. This controller will serve as a connector between the
solar panel and the batteries. The solar charge controller will ensure that the battery is charged
with the appropriate amount of solar power as per the battery manufacturer’s recommendations.
The solar charge controller ‘charging states’ are optimized to meet the requirements of most
standard lead acid batteries as well as flooded batteries. The RENOGY Off-Grid Solar Kit also
includes a mounting system comprised of sturdy aluminum Z-Brackets as well as the nuts and
bolts required to flat mount a solar panel onto a roof or any other flat surface. If you wish to
optimize your panel’s collection of sunlight by tilting the panel to a different inclination, an
adjustable tilt-mount may be purchased separately.
This manual will provide you with instructions on how to assemble the various
components of a RENOGY Off-Grid Solar Kit. Please refer to the separate Renogy Solar
Charge Controller Manual for detailed information about the installation, operation, and
programming of the solar charge controller.
Please read the manual carefully before installing or operating the solar kit to prevent personal
injury or damage to the components. If you have any concerns about the suitability of the kit for
your application, or doubts about any of the instructions in this manual, please contact
RENOGY Support at 1-800-330-8678.

Charge Controller Installation
The RENOGY Starter and RV Kits come with a PWM- type charge controller to optimally charge
your batteries from solar power. Each charge controller comes with a separate detailed manual.
It is recommended that you read the solar charge controller manual in detail. The instructions in
this section are only a brief summary of the information contained in the manual. Make sure the
solar panels and batteries are disconnected from the charge controller before mounting the
charge controller.
Recommended tools to have before installation:
Flathead Screwdriver
Multi-Meter
WARNING: Connect battery terminal wires to the charge controller FIRST then connect the solar
panel(s) to the charge controller. NEVER connect solar panel to charge controller before the battery.
CAUTION: Do not over-torque or over tighten the screw terminals. This could potentially break
the piece that holds the wire to the charge controller.
CAUTION: Refer to the technical specifications for max wire sizes on the controller and for the
maximum amperage going through wires.
Mounting Recommendations:
WARNING: Never install the controller in a sealed enclosure with flooded batteries. Gas can
accumulate and there is a risk of explosion.
The Adventurer is designed for flush mounting on a wall. It consists of a face plate with projecting
terminals on the backside for connecting the battery bank, panels, and optional sensors for
accurate battery voltage sensing and battery temperature compensation. If utilizing the wall
mount, then the wall will be required to be cut to accommodate the projecting terminals on the
backside. Make sure that the pocket of the wall cut leaves enough space to not damage the
terminals when the Adventurer is being pushed back into the cut out section of the wall.
The front of the Adventurer will serve as a heat sink, therefore it is important to ensure that the
mounting location is not near any heat generating sources and ensure that there is proper airflow
across the faceplate of the Adventurer to remove the heat dissipated from the surface.

1. Choose Mounting Location—place the controller on a vertical surface protected from
direct sunlight, high temperatures, and water. Make sure there is good ventilation.
2. Check for Clearance—verify that there is sufficient room to run wires, as well as
clearance above and below the controller for ventilation. The clearance should be at least
6 inches (150mm).
3. Cut out Wall section—the recommended wall size to be cut should follow the inner
protruding part of the charge controller while being careful not to go past the mounting
holes. The depth should be at least 1.7 inches (43mm).
4. Mark Holes
5. Drill Holes
NOTE: The Adventurer comes equipped with screws for wall mounting. If they are not
suitable try using Pan Head Phillips Screw 18-8 Stainless Steel M3.9 Size 25mm
length screws.
6. Secure the charge controller.
