Reference Guide
LiftMaster Solar Gate Operators feature a best-in-class
power management system that delivers power when
needed most to operate the gate while minimizing
power consumption at all other times. Power is
provided to the gate operator via batteries. The
batteries are charged from a solar panel(s) connected
to the operator. The number of solar panels required
is determined by whether the application is for a single
or dual-gate, daily cycle rate, control board current
consumption by feature and accessory, and region
of the country.
Solar panel(s) must be located in an open area clear
of obstructions and shading for the entire day. Snow,
heavy fog or heavy rain affect solar panel performance
and charge rate. Solar panels should be cleaned
regularly to ensure proper operation. LiftMaster Gate
Operators utilizing the solar option in cold weather
climates where temperatures reach below -32°F (0°C)
for more than 2 consecutive weeks require 33Ah
batteries in lieu of standard 7Ah batteries. This is
due to the effect of cold weather on batteries and a
reduced number of hours of sunlight during the winter
months. (see back page for details)
LiftMaster Solar Gate Operators are engineered to have low idle current draw including radio
receiver to maximize battery life and solar performance. It is important to note, the following
environmental factors can adversely affect battery performance in solar applications.
· Cold temperature (below 32°F (0°C))
· Snow cover on solar panel
· Reduced hours of sunlight in winter months
In geographic areas that experience cold temperatures below 32°F (0°C) for more than two
weeks in addition to any of the factors listed above, the following steps can be taken to ensure
best performance:
· Replace the standard 7Ah batteries with 33Ah batteries. (For linear actuators, use the
optional XL control box model XLSOLARCONTU)
· In states adjacent to Canada and Canadian provinces, increase the angle of the solar panels
by an additional 15 degrees (60 degrees total). This will optimize the solar panels for the
winter months and reduce the buildup of snow and ice on the panels.
Important note: Daily cycle rate and standby time will be reduced by at least 50% when
temperatures reach extreme cold temperatures below -4°F (or -20°C) for periods of more than
two weeks.
For best performance during the winter months, snow and ice should be removed from the solar
panel, moving parts on the gate and gate operator. In addition all snow should be removed from
the path of the gate to prevent nuisance reversals.
If heavy amounts of snow are expected over several days, the manual disconnect may be
engaged and the gate left open to allow access and snow removal. Once the snow is removed,
simply reengage the manual disconnect to resume normal operation.
