LiftMaster LA400XL20W Solar Swing Gate Operator Kit

Off-Grid Swing Gate Automation with Extended 33Ah Battery Capacity

The LiftMaster LA400XL20W Solar Swing Gate Operator Kit combines the LA400 linear actuator with an extended-capacity solar power system for residential vehicular swing gates where bringing AC power to the entrance is difficult or impractical.

Gate capacity depends on the length of the gate leaf. The LA400 supports up to 850 lb at 10 ft, 750 lb at 12 ft, 650 lb at 14 ft, or 550 lb at 16 ft. The 24 VDC actuator provides soft start and soft stop, electronic limits, inherent obstruction sensing, and approximately 15-18 second travel for a 90-degree opening.

The LA400XL20W package uses two 10W solar panels wired for a 24V, 20W charging system and two 33Ah batteries housed in LiftMaster's large metal solar control box. This provides substantially greater stored battery capacity than the standard LA400 package while keeping the system completely solar powered.

The LA400 is also compatible with myQ technology for remote gate monitoring and control when paired with compatible LiftMaster connectivity equipment. Security+ 2.0 wireless controls, optional expansion-board functions, loop detection, and additional monitored safety devices can be added based on the needs of the installation.

Conclusion

The LiftMaster LA400XL20W is designed for single swing gate installations that need the LA400 platform without running AC power to the gate. Its 20W solar array, two 33Ah batteries, large solar enclosure, myQ compatibility, and monitored safety integration make it a practical option for remote driveways and other off-grid residential entrances.

Solar performance depends on available sunlight, geographic location, accessory current draw, battery condition, gate weight, and daily traffic. Additional solar capacity may be required for higher-use installations or locations with limited sunlight.

Gate capacity should also be selected using both gate length and weight. The 850 lb rating applies to a 10 ft gate, while a 16 ft gate is rated up to 550 lb. The included LMRRUL provides one monitored external entrapment protection device, but additional monitored devices may be required based on the entrapment zones present at the installation.
