SOLAR STREET LIGHTING · AUSTRALIA

A round battery built for
solar street lighting.

This 25.6V 28.8Ah LiFePO4 pack was developed for an Australian solar street lighting system. The project progressed to batch production, with the earliest field installations beginning in 2020.

PROJECT OVERVIEW

Daily solar cycling in a compact cylindrical envelope.

The battery had to combine the required nightly energy with a slim round structure suited to the lighting system's installation space. The electrical design also needed a defined charge window, protected discharge path and practical cable routing for repeatable assembly.

The customer name, logo, order quantity and installation locations remain confidential.

ENGINEERING PRIORITIES

What matters in a solar lighting battery.

The final pack is selected around the solar input, nightly load, required autonomy, installation space and environmental conditions.

Solar charge profile

The controller voltage and available charging current must stay within the battery's confirmed charging window.

Nightly energy

Lamp power, operating hours and autonomy targets determine usable energy rather than capacity alone.

Mechanical fit

The round pack diameter, height, cable exit and service clearance are reviewed against the equipment cavity.

Outdoor conditions

Temperature exposure, daily cycling and enclosure protection shape the BMS and installation review.

PROJECT-SPECIFIC VERIFICATION

Electrical, mechanical and protection checks before production.

BMS protectionOvercharge, overdischarge, overcurrent, short-circuit, balancing and temperature protection.

Electrical checksCapacity, charge/discharge behavior, self-discharge and project-specific cycle-life verification.

Mechanical checksDrop and vibration testing were included in the approved project specification.

DELIVERED RESULT

From custom specification to batch production.

The project moved into batch production for the Australian solar street lighting application. The first field installations began in 2020, establishing a real project history beyond sample-stage development.

The specifications shown here describe this completed custom build. A new solar lighting project is reviewed against its own lamp load, controller, panel, autonomy, temperature and installation requirements.
