Technical Specifications

Integrated Solar Power System

The 50W fixture integrates the solar panel, battery, LED system, and controller into one outdoor lighting unit. The 18V monocrystalline silicon solar panel converts sunlight into electrical energy during the day, while the integrated LiFePO4 battery stores energy for nighttime operation.

The solar panel is specified with conversion efficiency of up to 24%, while MPPT tracking technology helps optimize solar energy harvesting under changing sunlight conditions.

LiFePO4 Battery Technology

The fixture uses a 32135 LiFePO4 battery system designed for repeated charging and discharging. The specification indicates more than 2,200 charge/discharge cycles and a battery life of more than 25 years under specified conditions, with approximately 80% efficiency.

Actual operating performance and battery life can vary according to sunlight availability, temperature, installation location, and usage conditions.

Intelligent Motion Sensor Lighting

The integrated motion sensor provides an energy-saving operating mode. When movement is detected, the light can increase to 100% brightness. When no movement is detected, the fixture can reduce brightness to a lower level, with the specification indicating an adjustable 10%-100% brightness range.

The product documentation indicates motion detection at approximately 8-10 meters, depending on installation and environmental conditions.

This operating strategy helps conserve stored battery energy during periods when the area is unoccupied.

Dusk-to-Dawn & Time Control

The solar street light combines three control methods:

• Light Sensor Control for automatic nighttime operation
• Time Control for scheduled lighting periods
• Motion Sensor Control for occupancy-based brightness adjustment

The time-control system can be configured across multiple time periods to balance illumination requirements and battery conservation.

Outdoor Construction

The fixture features an integrated die-cast aluminum housing designed to provide effective heat dissipation and outdoor durability. The IP66 rating provides protection against dust and powerful water jets, making the light suitable for exposed outdoor installations.

The recommended installation height is approximately 4-6 meters, with a 60 mm pole diameter specified for the mounting connection.

Recommended Applications

• Roadway Lighting
• Street Lighting
• Parking Areas
• Pathways
• Sidewalks
• Parks
• Campuses
• Gardens
• Farms & Ranches
• Fences
• Ramps
• Boat Docks
• Remote Areas
• Off-Grid Properties
• Commercial Outdoor Areas

Off-Grid Lighting Solution

Because the fixture generates and stores its own electrical energy, it can be used in locations where trenching, underground wiring, or extending utility power would be difficult or costly.

It is particularly suitable for remote pathways, rural roads, farms, ranches, parks, campuses, and other outdoor areas requiring standalone lighting.

Installation & Mounting

The fixture is designed for installation on compatible poles with a specified 60 mm pole diameter and approximately 100-105 mm connective section length.

The installation process includes:

1. Inspect the fixture and components for shipping damage.
2. Adjust the fixture angle using the M8 adjustment screws.
3. Secure the fixture to the pole using the mounting bracket.
4. Tighten the mounting hardware securely.
5. Confirm the sensor and nighttime operation after installation.

Professional installation is recommended. The solar panel should have unobstructed exposure to sunlight and should not be installed beneath trees or other structures that significantly reduce solar exposure.

Important Installation & Storage Notes

For reliable performance:

• Install the solar panel where it receives sufficient direct sunlight.
• Avoid locations with persistent shade or obstructions.
• Do not install the fixture in high-temperature, enclosed, or poorly ventilated areas.
• Store the product within the specified -25°C to +60°C storage temperature range.
• The documentation recommends charging and discharging stored units every three months.
• Faulty units should be serviced by qualified personnel.
• Actual runtime varies with sunlight, local weather, temperature, and operating settings.
