LiftMaster® Solar Gate Cycles per Day 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.

** Numbers above for solar daily cycles are representative of wired dual-gate installation. If your installation is a

wireless dual-gate setup use single gate cycle estimate and add in power draw for wireless dual-gate feature.

The map and daily cycle rate

shown are approximations based

upon the average solar radiation

and the temperature effects on

batteries in the given regions.

Local geography and weather

conditions may require additional

solar panels. Solar optimized

or wireless accessories are

recommended in order to minimize

power draw, as added accessories

draw power and affect the daily

cycle rate. For full details please
