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.
Accessories connected to your system will draw
additional power from the battery.
A second battery [FM150] is recommended for solar
and/or high traffic applications. See the accessory
catalog.
