Ứng dụng

Off-Grid Solar Floodlight Systems

Designed for outdoor solar floodlights with motion sensors or dusk-to-dawn operation. Ideal for illuminating parking lots, pathways, and security zones while withstanding extreme temperatures (IP65-rated enclosures). Supports energy-efficient LED arrays for 8–12 hours of runtime.

Weather-Resistant Garden & Landscape Lighting

Optimized for solar-powered garden lights, pathway markers, and decorative fixtures. Compact dimensions (56x56x75mm) minimize wasted space in underground enclosures, while high-temperature resistance ensures stable performance in direct sunlight or seasonal weather shifts.

Emergency Exit & Backup Power Systems

Provides reliable backup for emergency lighting grids in commercial buildings, warehouses, and public facilities during power outages. Compatible with 12V DC emergency exit signs, stairwell lights, and IoT-enabled safety systems requiring low-maintenance power.

Ưu điểm kỹ thuật

  • Tăng cường an toàn: Stable LiFePO4 chemistry eliminates thermal runaway risks, even in high-heat environments.
  • Tuổi thọ: 2000+ deep discharge cycles outperform lead-acid batteries by 5x, reducing replacement costs.
  • Temperature Resilience: Operates flawlessly from -20°C to 60°C, ideal for harsh outdoor installations.
  • Eco-Friendly: Zero maintenance, leak-proof design, and recyclable components align with sustainable energy standards.
