Wiltson Energy, the leader in advanced lithium iron phosphate battery technology, has today introduced its breakthrough low-temperature backup battery. They are specifically designed to fit in solar tracking systems with harsh and unstable weather conditions. This innovation guarantees direct charging and operates under sub-zero temperatures. These do not require additional external heating material, therefore reducing the costs of expensive renewable energy installations in cold climates.

Solar tracking systems are gaining mass acceptance in the global market due to their capability of increasing the energy production between 10% and 40% as opposed to the simplicity of fixed solar panel frameworks. Nonetheless, trackers often become impaired during cold weather conditions, where conventional batteries experience tragic capacity loss and slower discharge speeds.

Unlike conventional lithium and standard lead acid batteries, which can lose up to 30% of their capacity below freezing, standard lithium batteries require heating circuits. Wiltson 26650 low-temperature cell is capable of operating reliably at a wide operating temperature of -40C (-40F) to +60C (+140F). Functioning in low temperatures and charging without extra heating devices saves much time and expense on installation and maintenance.

Simply by providing a fuel-free, stable, and reliable source of power, Wiltson is also empowering renewable energy developers to deploy solar tracking systems in these areas. That might otherwise be considered too harsh an environment in which to operate options such as solar tracking systems - places like the Arctic, Siberia, Canada, and Northern Europe. This is specifically useful in off-grid remote sites or during adverse winter weather, wherein backup power is critical. Furthermore, the win addresses one of the industry's enduring issues and demonstrates that Wiltson Energy is a leader in addressing this issue in the increasingly important and growing battery energy storage industry.

Executive Statements

Robert Xie, CEO of Wiltson Energy

“This innovation represents more than just a technical upgrade — it is a step toward making solar tracker technology reliable in every climate. By ensuring uninterrupted operation, we are helping customers maximize energy yield.”

Daniel Fan, Project Manager at Wiltson Energy (acting as CTO role)

“Traditional battery systems either require preheating or shut down entirely in extreme cold, leaving trackers stuck and operators losing production. Our new 26650 LiFePO₄ low-temperature battery was engineered specifically for these conditions — it keeps solar trackers moving at –40°C without heating.”
