Determine Charging Option for Battery: Transformer OR Solar
IMPORTANT:
●
The transformer is designed for indoor use. If the transformer can be plugged only into an outside electrical outlet, a
weatherproof cover/housing (available at local electrical supply stores) must be used.
●
If your gate is more than 1000 ft. from an AC power source, you will need to use at least 10 watt solar charging power
to charge the battery [FM123]. Refer to the Solar Panel and Gate Activity chart below.
●
All low voltage wire used with the Mighty Mule gate operator must be 16 gauge dual conductor, stranded, direct burial
wire [RB509]. Do not run more than 1000 ft. of wire.
NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT
THE SAME TIME. It will damage the control board.
The table and map illustrate
the maximum number
of gate cycles to expect
per day in a particular
area when using from
10 to 30 watts of solar
charging power prior to the
battery depleting to a state where the unit will
not function. The figures shown are for winter
(minimum sunlight). Accessories connected to
your system will draw additional power from the
battery.
Deep cycle marine battery is recommended for
solar and/or high traffic applications.
