LiftMaster LA500SLRHARN Solar Harness for LA500

33Ah Battery Wiring Kit for LA500 Solar Applications

The LiftMaster LA500SLRHARN Solar Harness Kit is a replacement and installation harness for LiftMaster LA500 gate operator solar applications using 33Ah batteries. This harness is required for 33Ah solar configurations only and is used to connect the larger battery setup and solar panel wiring to the LA500 control system.

The kit includes the solar harness and battery jumper wire needed for the 33Ah battery layout. The harness has long red and black wires for the 33Ah battery connections and shorter red and black wires for the solar panel connections. This allows the LA500 solar system to be wired according to LiftMaster’s specified battery and solar panel configuration.

The LA500SLRHARN is intended for solar-powered LA500 installations where higher-capacity 33Ah batteries are being used instead of the standard battery configuration. It is commonly used during solar conversions, battery box updates, replacement harness repairs, or service work on LA500 gate systems configured for 33Ah battery backup.

Solar panels, batteries, gate operator, and control box are not included. Installation should follow the LA500 manual and LiftMaster solar harness wiring diagram, and all AC, solar, and battery power must be disconnected before service.
