Solar Panel Installation

Step 1: Slide the 1/4” bolts (F) through the bottom of each channel
so the threaded part of each bolt comes through top of frame,
position the pipe (D) between the bolts and place two clamps (C)
over the curved pipe onto the bolts. The clamp at the top of the
solar panel should fi t over the pin on the curved pipe. Secure with
the 1/4” nuts (E).

Step 2: Determine the site for installation
of the solar panel. It is important to install
the solar panel facing the path of the
sun where full sun will strike its face
throughout the day. The solar panel

cannot be shaded out or obstructed
by trees, bushes, buildings etc for
any part of the day. The curved pipe

(D) maintains the proper angle to the
sun. Secure the solar panel assembly
to a wooden post or fence using two
pipe clamps (C) and #2 lag screws (B)
as shown in the illustration. If your fence
post is metal, you will need alternative
hardware not provided, (i.e. U-clamps
or metal screws).

Tools Required :

• Slotted (flat blade) Screwdriver

• 7/16” open end wrench

IMPORTANT: the solar panel must be positioned facing the path of
the sun, due south and in an open area away from shade. It should
receive at least 8 hours of direct sunlight for a full charge.

Step 3: All Linear APeX powered gate operators have a POWER
IN terminal on their control boards marked 24V SOLAR PANEL for
connecting the solar panel wires (See illustration). Feed the free
end of the solar panel wires into the control box and attach them
to the 24V SOLAR PANEL terminals APeX control board. The RED
solar panel wire goes to the (+) POSITIVE Solar terminal and the
BLACK solar panel wire goes to the (–) NEGATIVE Solar terminal.
See diagram below.

IMPORTANT: Improper installation of these wires will cause
damage to the APeX controller or solar panel.

HINT: If the solar panel must be placed more than 10 ft. from the
control box (but less than 250 feet away), use multi-stranded, 16
gauge (AWG), direct burial, low-voltage wire. Never use telephone

wire or solid core wire.

IMPORTANT: To provide secure and moisture resistant splices for

solar panels use a direct burial splice kit for underground splices
and an above ground splice kit for above ground splices. These
splice kits can be found at hardware and electrical supply stores.

HINTS for Obtaining Maximum Output from Your Solar Panel

1. Place the panel facing due south
in the path of the sun, where full
sun will strike its face throughout
the day (minimum 8 hours).

2. Mount the panel using the curved
pipe provided to maintain the
proper angle to the sun.

3. For optimal effi ciency, wipe the
face of the panel frequently with
a soft, damp cloth. The output of the Solar Panel is variable
during the day depending on the intensity of the sun and the
angle of the rays striking the panel. The output may vary from
a few millivolts to as much as 44 volts. To check the output,
simply disconnect the solar panel leads from the control
board and connect them directly to a dc voltmeter. In bright
sunlight the panel output should read at least 34 volts dc at
approximately 300mA.

NOTE: All connections should be weather proofed using weather
proof splice kits available at hardware and electrical supply stores.

Use the table and map to determine the number of operational
cycles* per day to expect in your area, using 10 to 30 Watts of
charging power. Figures are shown for winter (minimum sunlight),
on a maximum loaded gate and do not account for the use of any
accessory items.

Accessories will draw additional power from the battery; the more
accessories you connect, the more power your system will require.

*An operational cycle is one full opening and closing of the gate.
*Number of openings per day will depend on the length, weight,

hardware and environmental conditions.
