Operates Reliably from –40°C (–40°F) to +60°C (140°F) with Direct Cold-Weather Charging, No Heating Required
DONGGUAN, China, Aug. 20, 2025 /PRNewswire/ -- Wiltson Energy, a leading innovator in advanced LiFePO₄ (lithium iron phosphate) battery solutions, today announced the launch of its next-generation 26650-format low-temperature backup battery for solar tracking systems. Designed for extreme climates, the new cell ensures stable operation and direct charging even below freezing — without additional heating components.
Solar tracking systems can increase energy yield by 10% to 40% compared to fixed-mount systems. However, in harsh winter climates, conventional batteries experience steep performance drops. Standard lead-acid batteries lose 20%–30% of capacity below 0°C (32°F), and typical lithium batteries face reduced output or even lithium dendrite growth risks during charging. These issues often cause trackers to freeze in place or shut down during outages, cutting into expected energy gains.
Wiltson's newly released low-temperature LiFePO₄ battery solves these challenges with an ultra-wide operating range of –40°C to +60°C (–40°F to 140°F). Unlike competing solutions that rely on heating elements or external warming circuits, Wiltson's 26650 cells can be safely charged directly below freezing, reducing cost and complexity while boosting efficiency.
Key benefits include:
- Extreme Temperature Performance: Reliable operation from –40°C to +60°C (–40°F to 140°F), ideal for cold-climate solar projects worldwide.
- Direct Cold-Weather Charging: Eliminates the need for heating controllers or circuits.
- High Power Output in Severe Cold: Maintains over 90% capacity at –40°C (–40°F), supporting up to 5C discharge to keep tracker motors at full torque.
- Uninterrupted Tracking: Ensures solar panels stay optimally aligned with the sun, even during severe cold or grid outages — safeguarding the 10%–40% generation advantage of solar trackers.
"Traditional battery systems either require preheating or shut down entirely in extreme cold, leaving trackers stuck and operators losing production," said Daniel Fan, Project Manager at Wiltson Energy. "Our new 26650 LiFePO₄ low-temperature battery was engineered specifically for these conditions — it keeps solar trackers moving at –40°C without heating."
"This innovation represents more than just a technical upgrade — it is a step toward making solar tracker technology reliable in every climate," added Robert Xie, CEO of Wiltson Energy. "By ensuring uninterrupted operation, we are helping customers maximize energy yield."
With its standard 26650 cylindrical form factor, the battery is ideal for modular deployment. It functions as both a primary power source and an uninterruptible power supply (UPS), switching seamlessly within 10 milliseconds during grid failures. This ensures consistent solar output — even in blizzards, polar nights, or other extreme conditions — maximizing uptime, reliability, and energy yield.

Wiltson Energy Launches 26650 LiFePO₄ Low-Temperature Battery for Solar Tracker Backup Power
ALULA, Saudi Arabia, Jan. 16, 2026 /PRNewswire/ -- Today marks the official opening of Desert X AlUla 2026, the landmark fourth edition of the international, open-air biennial exhibition. Arts AlUla, in collaboration with Desert X, welcomes visitors to experience a stellar line-up of Saudi and international multi-generational artists whose site-responsive earthworks, sculptures, and installations will engage in a powerful dialogue with the awe-inspiring landscapes and layered heritage of AlUla.
As a premier destination rich in ancient history and breathtaking nature, AlUla, located in Northwest Saudi Arabia, solidifies its position on the global stage as a dynamic, emerging land art destination with Desert X AlUla, the region's first public art biennale, and a key highlight of the AlUla Arts Festival.
The 2026 edition of Desert X AlUla brings together 11 acclaimed artists whose diverse works reflect a wide spectrum of ideas, materials, and traditions. From monumental kinetic sculpture to sound-based explorations above and below ground, each commission is deeply rooted in relationships to AlUla's distinctive environment, further cementing Desert X AlUla's reputation as a globally significant platform for site-responsive land art.
Desert X AlUla runs until February 28, 2026, as a cornerstone of the annual AlUla Arts Festival. Curated by Wejdan Reda, Zoé Whitley, with artistic direction by Neville Wakefield, and Raneem Farsi, its fourth edition explores 'Space Without Measure.' Inspired by Kahlil Gibran, the theme fosters contemplation of imagination within AlUla's natural settings. The exhibition, set in the desert canyons of AlUla, serves as a pre-opening programme for Wadi AlFann, offering a pivotal glimpse into AlUla's plans to create a permanent land art 'Valley of the Arts.'
Hamad Alhomiedan, Director of Arts & Creative Industries at the Royal Commission for AlUla (RCU), said: "At Desert X AlUla 2026, audiences will engage with art that deeply converses with AlUla's unique landscapes and rich heritage. These compelling commissions highlight AlUla's dynamic transformation into a major global destination, where ancient and contemporary expressions converge. This exhibition is part of our broader revitalisation of AlUla as a culturally rich destination to live, work and visit and integral to positioning AlUla in the global dialogue of contemporary art and as a precursor to monumental projects like Wadi AlFann."

About AlUla and Arts AlUla
Located 1,100 km from Riyadh, in North-West Saudi Arabia, AlUla is a place of extraordinary natural and human heritage. The vast area, covering 22,561km², includes a lush oasis valley, towering sandstone mountains and ancient cultural heritage sites dating back thousands of years to when the Lihyan and Nabataean kingdoms reigned.
The most well-known and recognised site in AlUla is Hegra, the principal southern city of the Nabataean Kingdom and Saudi Arabia's first UNESCO World Heritage Site. AlUla is also home to ancient Dadan, the capital of the Dadan and Lihyan Kingdoms and considered to be one of the most developed 1st millennium BCE cities of the Arabian Peninsula, and Jabal Ikmah, an open air library of hundreds of inscriptions and writings in many different languages. AlUla Old Town Village, a labyrinth of more than 900 mudbrick homes was developed from at least the 12th century and has been revitalised as the vibrant hub for visitors and residents.
The creation of Arts AlUla within The Royal Commission for AlUla (RCU) is a commitment to crafting the next chapters in a millennia of artistic creation – celebrating cultural inheritance and shaping a future inspired by artists built be artists. The work of Arts AlUla seeks to preserve this legacy: fuse the old with the new; the local with the international, keeping the arts central to the spirit of AlUla as a place of extraordinary natural and human heritage.
Wadi AlFann, meaning 'Valley of the Arts,' will be a global cultural destination for land art, unveiling from 2028 onwards, where era-defining works by artists from around the world will be permanently sited in the monumental landscape of AlUla, the extraordinary desert region of north-west Saudi Arabia.
