Solar Application Recommended for the LA500:
• Large Metal Control Box (XLM)
• A minimum of two 10W solar panels in series
• Two 33AH Batteries
• Battery Harness (Model LA500SLRHARN)
• Battery Tray (Model K10-36183)
We recommend LiftMaster low power draw accessories to minimize power draw, refer to accessory page.
Disconnect the expansion board for solar applications.
NOTE: Solar power is 24 Vdc at 60 watts maximum.
The solar panel(s) must be located in an open area clear of obstructions and shading for the entire day.
The gate operator is not supported in northern climates where temperatures reach below -4˚F. This is due
to cold weather and a reduced number of hours of sunlight during the winter months. Cycle rate may vary
from solar chart for areas that reach below 32˚F. Solar panels should be cleaned on a regular basis for
best performance to ensure proper operation.
