As telecom infrastructure continues to expand across the Middle East, the role of telecom towers is undergoing a profound transformation—evolving from traditional "basic backup power" nodes into intelligent hubs that demand high reliability, remote O&M (Operations and Maintenance), and asset security. Particularly in Saudi Arabia and surrounding markets, operators face challenges such as widely distributed towers, extreme ambient temperature fluctuations, and scattered sites. Consequently, their demands have transcended mere power supply duration, extending into deeper dimensions such as remote visual management, rapid maintenance response, and anti-theft protection for equipment assets.

Against this backdrop, Tianeng forged a strategic partnership with a Saudi Arabian telecom tower operator in 2023 to launch a 48V 150Ah energy storage rack-mounted case (PACK) solution project, aimed at providing highly reliable backup power support for distributed telecom towers. The battery cells used in this project are an industry-first, independently developed by Tianeng in a 3U 150Ah format. Targeting the actual pain points of the project, the R&D team deeply integrated customized functional modules—including anti-theft design, GPS positioning, and NC (Normally Closed) alarm systems—on top of standard energy storage functions. By adopting a modular and scalable architecture, this solution not only achieves rapid adaptation to different tower conditions and application requirements on the exact same system, but also greatly enhances the convenience of on-site maintenance while ensuring system stability.

Throughout the project's progression, the Tianeng team continuously tackled technical bottlenecks and optimized modules centered around high-reliability telecom tower scenarios. The seamless fusion of standard energy storage modules with customized customer requirements enabled highly efficient, rapid deployment capabilities. Notably, the project implementation phase innovatively introduced a "Remote Functional Testing and Video Acceptance" workflow. This initiative allowed customers to transcend geographical limitations and view functional verification results in real time. While drastically reducing cross-regional communication costs, it significantly shortened the acceptance cycle and gradually crystallized a mature overseas project delivery model defined by "Technical Adaptation + Local Partnership + Certification Synergy."

Entering the batch delivery and O&M phase, the team further leveraged an international digitized order tracking system to achieve full-process visual management from manufacturing and logistics to after-sales support, ensuring the precise advancement of multi-batch projects. To date, this model has successfully completed multiple batches of stable deliveries. Thanks to its excellent adaptability, it has been replicated in telecom energy storage projects in countries such as the Philippines and Yemen, fully validating its generalized capability across complex scenarios in diverse nations.

Judging from project practices, telecom tower backup energy storage is progressively evolving from a single, traditional backup power product into a systematized solution that combines modular design, remote verification, digitized delivery, and asset management capabilities. The R&D response mechanism and overseas delivery experience accumulated by Tianeng in the Middle East telecom energy storage project have been transformed into a scalable and replicable capability framework. This will continue to provide powerful support for more markets with high temperatures, high dispersion, and demanding O&M requirements.
