Kototerk Split Solar Street Light ZD & GD Series | 40W-120W High-Efficiency MPPT Solar Road Light
The Kototerk KT-FTZD & KT-FTGD Series Split Solar Street Lights represent the next generation of high-performance commercial outdoor lighting. By separating the solar panel from the light fixture, these series allow for optimal solar orientation to maximize energy collection. Powered by ultra-efficient MPPT controllers, heavy-duty LiFePO4 lithium batteries, and high-density LED chips, they deliver an industry-leading luminous efficacy of up to 190LM/W, making them the ideal choice for municipal roads, industrial zones, and highway lighting projects.
Key Features
-
Ultra-High Luminous Efficacy: Equipped with premium SMD5050/SMD3030 chips, reaching up to 189-190 LM/W (FTZD Series) and 180 LM/W (FTGD Series) to deliver up to 21,600LM of crisp brightness.
-
Smart MPPT Controller: Built-in Maximum Power Point Tracking (MPPT) intelligent controller ensures optimal charging efficiency even on overcast days, extending the lifespan of the system.
-
Next-Gen LiFePO4 Battery: Utilizing automotive-grade Lithium Iron Phosphate (LiFePO4) batteries (up to 1152WH), ensuring superior thermal stability, safety, and a deep cycle life.
-
Monocrystalline Solar Panel: Features high-efficiency Mono solar panels with up to 23.8% conversion efficiency for rapid energy replenishment.
-
Smart Energy Management: Customized multi-stage dimming profile (e.g., 100% for the first 4 hours, 50% for the middle 2 hours, and 30% for the last 6 hours) to guarantee 3 to 5 continuous rainy days of backup power.
-
Heavy-Duty Die-Casting Aluminum: Built with rugged die-casting aluminum housings and high-transmittance PMMA lenses (>95%) for excellent heat dissipation and extreme outdoor durability.
