LiftMaster LA412PKGUL Dual Solar Gate Operator Kit

Off-Grid Dual Swing Gate Automation with Solar Charging

The LiftMaster LA412PKGUL Dual Swing Gate Operator Kit is a solar-powered system for automating two vehicular swing gate leaves where conventional AC power is unavailable or impractical. This configuration combines the LA412PKGUL primary package with an LA412DCS secondary actuator, allowing both gate leaves to operate from one control system.

Each LA412 actuator supports up to 850 lb at 10 ft, 750 lb at 12 ft, 650 lb at 14 ft, or 550 lb at 16 ft per gate leaf. The system uses 12 VDC motors with all-metal gear drives, electronic limits, soft start and soft stop, inherent obstruction sensing, and programmable bi-part delay for coordinating dual gates.

The secondary operator connects to the primary control box through the included extension cable and junction box. The kit also includes battery power, a 10-watt solar panel, and a monitored photoeye. Actual daily gate cycles depend on geographic location, available sunlight, solar panel capacity, battery configuration, accessory load, and the frequency of operation of both gate leaves.

Dual Gate and Solar Considerations

The LA412DCS secondary actuator is wired back to the primary control box, allowing both gate leaves to be controlled from the same board. Each actuator's open and close limits are programmed individually, while the bi-part delay setting can be used when one gate leaf needs to open first and close last because of an overlapping gate design or locking arrangement.

The included 10-watt solar panel provides the starting solar charging configuration, but solar requirements should be sized for the actual installation. Dual gates consume more energy than a single gate, and additional solar capacity may be necessary depending on daily cycles, accessories, battery current draw, geographic solar zone, and seasonal sunlight.

Gate capacity is also based on the length and weight of each individual leaf. The 850 lb rating applies to a 10 ft leaf; a 16 ft leaf is rated up to 550 lb.

Conclusion

The LiftMaster LA412 dual configuration is designed for off-grid properties that need coordinated automation of two swing gate leaves without running AC power to the entrance. Before ordering, verify the length and weight of each gate leaf and evaluate the site's expected cycle count, accessory load, solar exposure, and monitored entrapment protection requirements.
