WARNING
To prevent electric shock, exercise extreme caution at all times when
installing, maintaining, and operating this equipment. This equipment
may generate dangerous voltages. Cooper Crouse-Hinds has
incorporated every practical safety precaution into this equipment;
however, photovoltaic modules will create electricity whenever exposed
to sunlight, and batteries can store electricity for several days regardless
of light conditions. Special electrical regulations may apply because
these cells create direct current.
WARNING
To prevent component damage or electric shock, avoid touching any
component or any part of the circuitry while the equipment is operating.
Do not place heavy loads on associated system cables or maneuver
them in a manner which may expose personnel or equipment to current.
Do not connect system cables when the terminals are wet or damp. Do
not disconnect cables under load.
WARNING
To prevent damage to this system, do not concentrate the light on the
surface of these cells under any circumstances to increase the electrical
output of the system. The photovoltaic modules are only intended to
operate under normal sunlight conditions.
WARNING
To prevent injury, death, or damage to your photovoltaic system, be
sure to follow all warnings and notes in this Instruction Sheet and follow
all applicable local and national codes when installing, maintaining, and
operating this system.
Introduction to Photovoltaic Power Systems
This photovoltaic power system operates by converting the sun’s radiation
into usable power in the form of electricity as direct current. For nighttime
and low ambient light level situations, the load is provided by the battery
back-up of the system. This battery is charged via a controller by the
photovoltaic module which is responsible for converting the sun’s energy.
The diagram below (see Figure 1) describes how the system is wired.
Power is produced as soon as sunlight reaches the photovoltaic module.
This power passes through the terminal block and into the controller. The
controller splits this power to the battery and load as needed, and sends
the power to both via the terminal block. The power can only flow from the
photovoltaic module and not back into it (because of factory-installed
safeguards in place in the system). The power can also only flow to the
load and not from it. The battery has power both flowing into it (charging
during the day) and out from it (discharging to the load when required).
Circuit protectors are used to protect the system from electrical spikes and
short circuits. A low voltage disconnect is built into the controller.
Since these systems rely on sunlight for power, it is important that they are
placed in a location which is optimal for sunlight usage. The location is
given a rating in Equivalent Sun Hours (ESH), which is an indicator of the
amount of sunlight which will reach the photovoltaic module. The system
will rely less on battery operation and more on the photovoltaic module
power production in areas with a higher ESH.

WARNING
To avoid sparking, do not install, clean, or maintain the system when the
area is classified as hazardous.
Never install if components appear damaged or incorrectly wired from
the factory.

Prior to Installation
Care must be taken to ensure the safety of those installing this
equipment. Always verify that the method of installation will be suitable
for the environmental and operating conditions in which this system will
need to perform.
Components
This solar energy system is comprised of system components. Not
included is the SCH40 pole needed for mounting this equipment or any
other associated supplies (concrete, grounding rod, U-bolts, etc.).
During Installation and Maintenance
Under no circumstance should this system be installed or operated
with a damaged solar panel backsheet. Extra care should be taken
not to damage the backsheet by dropping it or hitting it with an
object. Always mount the solar modules so that the junction box is located
at the upper edge of the module. These should also be installed at an
angle of no less than 10 degrees (10º) from the horizontal for ease of
regularly scheduled cleaning and to help in self-cleaning. Make certain
that all electrical connections are securely connected and are done so in a
manner to reduce the chance of unauthorized personnel tampering
(purposely or inadvertently) with the apparatus. Never attach anything to
the back of the module, and make certain to allow for adequate ventilation
to the back of the module to reduce the risk of heat build-up.
CAUTION
To prevent injury, death, or damage to your photovoltaic system, use
caution when handling this equipment. Much of this equipment is heavy
and should be handled by two people. Never install this equipment
when weather conditions may pose a risk of danger. Always use
insulated tools and never wear jewelry or other metallic clothing, as
these modules may generate electricity whenever light is present.
Always cover the solar array’s front surface with an opaque material to
reduce the risk of electrical generation during installation and when
performing maintenance operations. Do not install wiring when fingers
are wet.

Pole Installation
Always check with your local utility companies before digging for pole
installation. Failure to do so may result in injury, death, or harm to
essential equipment buried underground.
The pole used as the structural support for the photovoltaic module with
mounting hardware and battery box with components must be designed to
withstand all possible environmental conditions for the area without failure.
This includes wind speeds, rainfall, snowfall, soil erosion, and any other
environmental conditions which may exist in the area but are not listed.
The pole should be installed in accordance with current local code and
ASTM standards for in-ground mounting of structure poles if being directly
buried. The pole must be level so that the battery box and photovoltaic
module will not exert an excessive amount of torque on the pole, and so
that the components are angled properly.
Components have been designed to withstand 90 mph winds, if installed
properly. Be sure to follow all instructions for installation, and a type
SCH40 pole, as a minimum.
Photovoltaic Panel Mounting
Only the included panel mounting kit for side-of-pole installation should be
used for installing this panel. A galvanized SCH40 pole between 2” and 4”
(nominal) should be used and must be supplied by others. Four (4) U-bolts
are required (not provided) and should be sized to the diameter of the pole.
Care must be taken to not over-torque any of the bolts used for mounting
the panels and frame members. Check for missing parts before installing.
FRAMES FOR LARGE SOLAR ARRAYS (Page 5)
1. Begin by installing the top and bottom horizontal cross bars to
the pole using all four (4) U-bolts. Care must be taken to ensure
these are level and parallel to another. Install these
approximately 20” apart. These will be adjusted later.
2. Install the four (4) aluminum angle mounting feet to the top and
bottom horizontal cross bars equidistant from center using eight
(8) 5/16” stainless steel bolts, nuts, and washers supplied.
Orient these according to Figure 3.
3. Install the upper right and left side panel arms to the mounting
feet. Position these as shown in Figure 4 using two (2) 5/16”
stainless steel bolts, nuts, and washers supplied.
4. Install the lower side panel arms to the mounting feet and finally
to the upper panel arms as shown to create an offset “V” shape
using four (4) 5/16” stainless steel bolts, nuts, and washers
supplied.
5. Carefully attach the photovoltaic module to the upper left and
right side panel arms using the four (4) 1/4” 316 stainless steel
bolts, nuts, and washers provided. Proceed to Step 6.
FRAMES FOR SMALL SOLAR ARRAYS (Pages 6-7)
1. Attach two lateral braces to solar array with provided hardware.
2. Mount angle brackets to desired location on main horizontal
channel with provided bolts (using lateral braces as a guide for
spacing).
3. Use U-bolts to fasten horizontal brace to pole.
4. Angle solar panel facing south at the appropriate angle.
5. Proceed to Step 6.
6. THIS STEP REQUIRES AT LEAST TWO PEOPLE.
Carefully loosen the two (2) U-bolts holding the bottom
horizontal cross bar as well as the two (2) bolts holding the
upper left and right side panel arms. Loosen the bolts
connecting the upper and lower side panel arms to the lower
side panel arms. Loosen the lower side panel arm bolts. DO
NOT LOOSEN ANY OTHER BOLTS ON THIS ASSEMBLY AT
THIS POINT, AS IT WILL BECOME DANGEROUSLY
UNSTABLE. Care must be taken to support all members of the
assembly and to not twist the photovoltaic module.
7. Adjust the arms to change the angle of the panel to the desired
angle with regard to the position of the sun. The panel must be
aimed south (toward the equator, with tilt angles shown in Figure
5).
8. Tighten all bolts loosened in the previous steps, taking care to
not over-torque or strip any of them.
9. Wire the cable assembly into the solar terminals within the
enclosure as shown in Figure 8. Tighten cable gland to secure
to enclosure.
10. Wire the other end of the cable assembly to the solar panel.
Ensure to latch the junction box after installing the cable, and
that the junction box sealing gasket has been inserted into its
groove. The top of the PV panel is where the junction box is
located and the panel should always be mounted with the
junction box at the top. The junction box is on the underside of
the panel and that the panel must be oriented as such when
attached to the mount.
CAUTION
To prevent injury, death, or harm to essential equipment, the pole must
be grounded per NEC/CEC. A separate ground may be required if the
pole does not offer a suitable means of grounding to Earth.

Battery and Control Box Mounting (requires 2 people)
The battery box and controls enclosure should come pre-assembled with
all major components. The physical mounting of this only involves placing
the box below the photovoltaic module also attached to a SCH40 pole.
1. Place the control box below the photovoltaic module far enough
away that it does not impede ventilation of the box or module. Make
certain that the distance is short enough to allow for the cable
connections to the top of the solar module to reach the bottom of the
control box. The 2 conductor #10AWG cable is approximately 15’ long,
and is provided with cable glands.
2. Hold the box in place and loosely secure the top using a U-bolt.
3. Attach the bottom U-bolt while still holding the box in place.
4. Level the enclosure so that the battery is in the upright position
inside of the enclosure relative to the ground.
5. Tighten the top U-bolt.
6. Tighten the bottom U-bolt.
NOTE: If a suitable flat surface is used for mounting, then appropriately
sized hardware must be selected and must be 316 stainless steel for
corrosion protection.

WARNING
To prevent injury, death, or damage to your photovoltaic system,
extreme caution should be taken whenever entering the control cabinet
due to energized components.
Photovoltaic panels generate power whenever exposed to ANY light.
Cover the panel entirely prior to wiring or servicing with an opaque
cover.
Batteries are intended to store energy, and will shock, spark, or explode
if the terminals are touched or crossed.
Prior to installation or servicing, switch all disconnects to OFF position
and use only insulated tools.
CAUTION
For optimal performance and electrical safety, the battery must ALWAYS
be positioned upright in the control box.
Terminal
Strip

Electrical Connection
Note that batteries can explode if improperly connected. Never short
circuit a battery by “jumpering” it for any reason.
A negative ground system is required. To ensure proper ground, the
negative terminal of the battery must be directly wired to the
enclosure chassis.
The control box will arrive with the voltage regulator, circuit breakers, and
surge protector (when supplied) pre-wired in the enclosure.
Installation and Operation Notes:
• The controller, battery, and solar panel should be wired via the
terminal block per the wiring diagrams (see Figure 8) on page 10.
• Be sure to connect the load last. If the red indicator is lit, then
the battery capacity is low and should be fully charged before
completing system installation.
• The controller is shipped with a jumper installed for use with
sealed batteries. This jumper will optimize sealed battery
charging performance and should be used at all times.
• For effective surge protection, the negative battery conductor
must be properly grounded according to local code.
• The green LED indicator will turn on any time the photovoltaic
module is transferring energy to the controller. This will turn off
at nighttime. There will be a small amount of energy at all times
going to the battery when the green LED is on.
• The module includes an automatic low voltage disconnect (LVD)
feature which disconnects power to the load if the battery charge
falls below 11.5 volts. The red LED indicator will also turn on if
this occurs. Once the battery is charged to 12.6 volts, the load
will be reconnected and the LED will turn off.
• The controller does not need a blocking diode because it
automatically prevents reverse current leakage from discharging
through the module at night and when battery power operation is
occurring.
• The connectors are made to accept up to AWG #10 clamped to
20 inch-pounds. This connection is normally made at the factory.
• If the battery becomes disconnected, the photovoltaic module
will continue to provide power to the controller, which will provide
power to the load until there is not enough sunlight available to
power the load.
• Auxiliary devices may be used to charge the battery without
needing to disconnect the battery from the controller.
• Once installed, ensure that no wires or contacts are loose.
• Contact Cooper Crouse-Hinds for breathers/drains, cable glands,
or other weatherproofing accessories.

WARNING
To prevent injury, death, or damage to your photovoltaic system, all
circuit protectors should be in the OFF position until all electrical
connections are made. Connections should ONLY be made to the
terminal block and should NEVER be made directly to the solar
controller. Remember that the photovoltaic module may at any time be
producing electricity, so extra care must be taken to properly ground all
equipment and use insulated tools, as well as remove all jewelry.
Always follow electrical code for your area when installing one of these
systems, as failure to do so could result in injury or equipment failure.
Make certain that no bare wires come in contact with any metal surfaces
which they are not designed to be connected to.
