Wiltson Energy Unveils Revolutionary Low-Temperature LiFePO₄ Battery for Solar Trackers



DONGGUAN, China — August 20, 2025 - Wiltson Energy, a leader in the development of advanced lithium iron phosphate (LiFePO₄) battery solutions, has officially launched a groundbreaking 26650-format low-temperature backup battery tailored for solar tracking systems. This innovative product is engineered to operate efficiently in extreme climates, allowing direct charging even in sub-zero temperatures without the need for additional heating.

Solar tracking systems have become increasingly popular due to their efficiency, boasting energy yield increases between 10% and 40% compared to traditional fixed-mount systems. However, conventional batteries often face significant challenges in harsh winter conditions, with standard lead-acid batteries losing 20% to 30% of their capacity at freezing temperatures, while typical lithium batteries exhibit reduced performance or grapple with risks like lithium dendrite growth during charging.

In response to these challenges, Wiltson's new low-temperature LiFePO₄ battery is designed to function effectively within an impressive temperature range from -40°C (-40°F) to +60°C (140°F). Unlike competitor models that depend on heating elements or specialized warming circuits, the 26650 cells can be directly charged at sub-zero temperatures, considerably lowering both installation costs and complexity while significantly enhancing overall efficiency.

Key Features of the New Battery:


  • - Extreme Temperature Performance: Designed for reliable operation from -40°C to +60°C, this battery is ideal for solar projects in cold climates worldwide.
  • - Direct Cold-Weather Charging: The battery eliminates the need for additional heating controls or circuits, simplifying installation and maintenance requirements.
  • - High Power Output in Severe Cold: The battery maintains over 90% of its capacity at -40°C, capable of supporting up to 5C discharge, enabling tracker motors to perform at peak torque.
  • - Uninterrupted Tracking: The system ensures that solar panels remain optimally aligned with the sun, even in challenging winter conditions or during grid power outages, thus safeguarding the substantial energy generation advantages of solar trackers.

"Conventional battery systems either require preheating or shut down entirely in extreme cold, leaving solar trackers immobilized and operators facing production losses," stated Daniel Fan, Project Manager at Wiltson Energy. "Our new 26650 LiFePO₄ low-temperature battery was specifically designed to maintain the functionality of solar trackers even at -40°C without the need for heating."

Robert Xie, CEO of Wiltson Energy, added, "This innovation is not merely a technical advancement; it's a significant move toward ensuring that solar tracking technology operates reliably across all climates. By ensuring continuous operation, we enable our customers to maximize their energy yield."

The battery is built in a standard 26650 cylindrical format, making it exceptionally suitable for modular deployment. It serves dual purposes, functioning as both a primary power source and an uninterruptible power supply (UPS), with a seamless switch between the two modes in under 10 milliseconds during any grid failure. This characteristic guarantees that solar output remains steady—irrespective of blizzards, polar nights, or other demanding conditions—ultimately providing maximum uptime, reliability, and efficiency in energy production.
