LiftMaster K94-37236 Solar Battery Harness Kit for Compatible 7Ah and 33Ah Systems
LiftMaster K94-37236 Solar Battery Harness Kit for Compatible 7Ah and 33Ah Systems
The LiftMaster K94-37236 solar battery harness kit provides the wiring connections specified for supported LiftMaster gate-operator battery and solar arrangements. Its application depends on the operator voltage, battery configuration and control box. It is intended for the manufacturer-listed battery arrangements, including specified 7Ah and 33Ah applications, rather than universal battery wiring. Confirm the operator, control box and charging configuration together; the harness does not include batteries, panels or a complete solar conversion system.
Compatibility — Models, Versions and Exclusions
| Model or selection point | Compatibility requirement |
|---|---|
| 12V RSL12VDC / RSW12VDC | Listed in the harness instructions; use the matching battery arrangement. |
| 12V LA412DC | Specified only for the 33Ah application with XLSOLARCONTDC control box. |
| 24V LA400DC / LA500DC | Listed applications; confirm battery arrangement and system revision. |
| 24V CSL24VDC / CSW24VDC | Listed applications; use the applicable harness diagram. |
| Other operators or battery packs | A shared 7Ah or 33Ah capacity is not evidence of fit. |
Why Voltage, Capacity and Charging Configuration All Matter
Battery capacity describes stored energy; it does not identify the required wiring arrangement. Two installations using the same capacity can have different system voltages, connector requirements and charging controls. Treat the harness as one component of a documented power configuration, not as a way to convert an arbitrary operator to solar operation.
Before purchase, provide the control-box label, the number of batteries, each battery’s voltage and capacity, and the charging arrangement already in use. The installer should identify which existing leads are damaged or missing. Do not add panels, alter battery connections or combine charging sources on the strength of the harness name alone; the complete system must support the proposed arrangement.

Manufacturer-Listed Applications
The harness instructions list RSL12VDC and RSW12VDC 12V operators, plus LA412DC for the specified 33Ah arrangement with the XLSOLARCONTDC box. Listed 24V applications include LA400DC, LA500DC, CSL24VDC and CSW24VDC. Use the appropriate diagram for the actual equipment revision.
The kit provides different leads for different battery arrangements. Unused leads in one application do not mean every supplied lead should be connected.
Before Ordering
- Identify the operator and control-box model.
- Confirm the required battery capacity and system voltage.
- Check whether the installation uses AC charging, solar charging or an approved combination.
- Match the harness reference in the applicable manual.
Frequently Asked Questions
Does this kit include batteries or solar panels?
It is a wiring-harness kit. Batteries and solar panels are separate system components.
Can I use it on any gate operator with a 7Ah battery?
No. Battery capacity alone does not establish connector, voltage or charging-system compatibility.
Safety Warnings — Read Before Installation or Service
- WARNING: Battery circuits can remain energized after mains power is switched off. Incorrect connections can damage equipment and create an injury hazard.
- A qualified installer must isolate all applicable AC, solar and battery supplies before wiring.
- Follow the exact diagram for polarity and battery arrangement. Do not improvise connections or connect every supplied lead simply because it is present.
- Secure the wiring away from moving parts and restore normal operation only after the work area is clear and the system has been checked.
Related Products and Important Differences
- K001A6039 LA400 control board — a control-system identification reference when inspecting an older LA400; this link does not establish harness compatibility.
- LMWEKITU monitored wireless edge kit — a separate safety accessory to evaluate if the broader project includes work on gate-mounted edge wiring. It is not a battery harness or solar charging component.
More Questions Before Ordering
Will this increase the number of daily solar cycles?
A harness alone does not establish operating capacity. Daily demand, charging equipment, site conditions and the approved battery system must be assessed together.
Can I use a garage-door backup battery because its capacity looks similar?
Do not select batteries or leads by capacity alone. Match the gate operator’s specified voltage, battery type, connectors and charging configuration.
