Application Background

This battery solution is specifically designed for photovoltaic (PV) tracker systems, suitable for solar tracking control, outdoor energy management, and off-grid monitoring applications.

The system must operate continuously in harsh outdoor environments, ensuring stable control power supply for tracking accuracy, reliability, and environmental adaptability.

Project Challenges

  • Continuous low-current operation (~0.5A) requiring stable long-term power support
  • Harsh outdoor temperature range (-20°C to 60°C) with high reliability requirements
  • Exposure to long-term outdoor vibration, humidity, and temperature cycling
  • Limited installation space (70 × 79 × 40 mm) requiring compact design

Customized Battery Solution

  • 7S1P 25.2V platform (65.52Wh) ensuring stable power for PV tracking systems
  • Low-power optimized design for efficient and continuous tracking control support
  • XT connector with gold-plated contacts for enhanced electrical reliability
  • Comprehensive protection system (overcharge, overdischarge, overcurrent, short circuit, temperature, ESD) ensuring safe outdoor operation

Application Results

  • Stable power supply improves reliability of photovoltaic tracking control systems
  • Enhanced durability under long-term outdoor environmental exposure
  • Improved connection stability in vibration and weather-affected conditions
  • Overall system safety and operational reliability significantly strengthened
