Project Overview

Project Site: Croatia Construction Area – Reliable high-brightness illumination throughout the night

Product Model: AC/DC SSL-A2-120W Hybrid Integrated Solar Street Light
Project Location: Croatia
Project Type: Construction Site Lighting
Key Requirement: Stable full-night high brightness (10–12 hours) with AC power backup for continuous operation, even during the rainy season

Project Background & Challenges

Construction sites operate around the clock and demand consistent, high-quality illumination for safety and productivity. Traditional solar lights often struggle during prolonged cloudy or rainy periods, leading to dimming or complete power loss. The client needed a solution that could guarantee 10–12 hours of full-brightness lighting every night, regardless of weather conditions, while minimizing electricity costs.

Polybrite Solution

Polybrite recommended the AC/DC SSL-A2-120W hybrid solar street light with a detachable battery box:

· Hybrid AC/DC Power System: Primary solar power with automatic seamless switch to AC grid backup.

· Ultra-Fast Switching: Switches to AC supply within 20–30ms when battery level drops during extended bad weather — so fast that the lights show no visible interruption.

· Intelligent Operation: Automatically switches back to solar/DC mode once the battery is recharged, significantly reducing electricity costs.

· High Performance: 120W high-efficiency LED delivers strong, stable brightness with excellent uniformity.

· Practical Design: Detachable battery box for easy maintenance; robust build quality suitable for harsh construction environments.

This innovative hybrid solution ensures reliable all-night illumination while maximizing the use of free solar energy.

Project Results & Client Feedback

The project has been running successfully with outstanding performance:

· Uninterrupted High Brightness: Delivers consistent 10–12 hours of full-power lighting every night, even during the rainy season.

· Zero Downtime: Seamless AC backup ensures lighting continuity without any noticeable flicker or interruption.

· Significant Cost Savings: Prioritizes solar power and only draws from the grid when necessary, effectively reducing overall electricity expenses.

· Enhanced Safety: Provides reliable illumination for workers and vehicles on site, improving operational safety.

The client was highly satisfied with the solution’s reliability and intelligent design, confirming that Polybrite’s AC/DC hybrid system fully met their strict requirements.
