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 XLSOLARCONTUL)
· 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.
