1. Determine Charging Option for Battery: Transformer OR Solar
NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT
THE SAME TIME. It will damage the control board.
IMPORTANT:
• The Mighty Mule 200 is designed and intended for use with a 12 Volt automotive or marine type battery. The
battery must be placed inside a weatherproof case and located within 6 feet of the opener arm. The 8 foot
harness supplied connects the battery to the opener arm.
• 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 5 watts solar
charging power to charge the battery [FM121]. Refer to the Solar Panel and Gate Activity chart below.
• All low voltage wire used with the GTO Gate Operator must be 16 gauge dual conductor, stranded, direct
burial wire [RB509]. Do not run more than 1000 ft. of wire.
The table and map illustrate
the maximum number of
gate cycles to expect per
day in a particular area when
using from 5 to 30 watts of
solar charging power. The
figures shown are for winter
(minimum sunlight). Accessories connected to your
system will draw additional power from the battery.
