For optimal efciency, 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 22 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 18 volts dc at approximately
300mA.
STEP 3:
Make sure control box is OFF. Feed the free end of the solar panel wires into the control box
and attach them to the appropriate terminals on the 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. Improper
installation of these wires will damage the opener's control board.
Below are examples of solar terminals on various Mighty Mule and GTO/ACCESS SYSTEMS control boards.
If you do not see an illustration of your control board below, please refer to your gate opener Installation
Manual for instructions on wiring the control board. Or you may call GTO's Technical Service Department at
(800)543-1236 or (850)575-4144 for assistance.
NEVER USE THE SOLAR PANEL AND THE AC TRANSFORMER AT THE SAME TIME! It will
damage the control board.
