ONESUN's Leadership in Global Energy Storage Solutions
In the context of accelerating global energy structure transformation towards green and low-carbon development, energy storage technology is becoming core infrastructure supporting new energy expansion. Particularly in telecommunications, power peak-shaving, distributed energy, and off-grid applications, 48V (51.2V) Lithium Iron Phosphate (LiFePO4) systems, with their superior safety, long cycle life, and excellent stability, are becoming the industry mainstream choice. Against this industrial backdrop, China's ONESUN company, with its forward-looking technology layout and global strategy, is becoming the preferred partner for an increasing number of overseas clients establishing localized battery manufacturing capabilities.

ONESUN: Pioneer and System Solution Provider
As one of China's earliest enterprises focused on comprehensive photovoltaic energy storage system solutions, ONESUN can be considered an industry pioneer. The company was the first in China to propose an "integrated photovoltaic + energy storage product ecosystem," and was also the first to drive the upgrade of lithium battery systems from standalone products to "system solutions." While the industry was still in its exploratory phase, ONESUN had already clearly established a product model centered on lithium batteries, combined with inverters, Energy Management Systems (EMS), and cloud platforms, to create a complete energy ecosystem. This vision has been widely validated today and has become the standard development path for the global energy storage industry.

Comprehensive Product Portfolio
ONESUN has constructed a complete matrix covering residential energy storage, commercial and industrial storage, and large-scale BESS (Battery Energy Storage System). For the telecommunications sector, ONESUN has strategically launched standardized 48V (51.2V) 16S LiFePO4 battery modules with capacities ranging from 100Ah to 150Ah, supporting both rack-mounted and outdoor cabinet deployments. These systems feature high reliability and flexible expansion capabilities, meeting the requirements for long-term stable power supply at telecommunications base stations. Simultaneously, the modules support parallel operation, making them suitable for complex multi-site and multi-load application environments.

Technical Core Competencies
ONESUN's core competitive advantages extend beyond cell and battery pack manufacturing to encompass complete system architecture capabilities. The company's BMS (Battery Management System) supports multiple communication protocols including CAN and RS485, with open interfaces that facilitate customers' secondary development and system integration. This is particularly critical for partners seeking to gradually establish independent R&D capabilities locally. ONESUN provides not only standard products but also system architecture guidance, communication protocol support, and interface documentation, helping customers rapidly upgrade their capabilities from "assembly" to "independent R&D."

Flexible OEM/ODM and SKD/CKD Cooperation Models
Notably, ONESUN demonstrates exceptional flexibility in OEM/ODM and SKD/CKD cooperation modes. Addressing different national industrial policies and market demands, ONESUN can provide comprehensive one-stop solutions ranging from core component supply to complete factory turnkey delivery. Whether during initial battery pack assembly or subsequent local PCB design and BCU (Battery Controller Unit) development, ONESUN provides technical collaboration and continuous support. This "accompanying growth" cooperation model has enabled ONESUN to establish over 300 successful partner factory cases globally.

Why Enterprises Choose ONESUN
The fundamental reason more and more enterprises select ONESUN is that the company is not merely a product supplier but a "solutions enabler."
Product Quality
First, in terms of quality, ONESUN maintains high-standard battery cell systems and clearly differentiates Grade A and Grade B products, ensuring customers receive transparent and authentic performance assurances at different budget levels.
Integrated System Capabilities
Second, regarding system capabilities, ONESUN possesses vertical integration spanning from battery cells, battery packs, inverters, to complete BESS systems, significantly reducing the complexity of multi-supplier coordination for customers.
Global Localization Experience
Third, in global experience, ONESUN has successfully implemented localized manufacturing projects across multiple regions including Africa, Southeast Asia, the Middle East, and Latin America, possessing rich experience in cross-border technology transfer and factory construction.

Advanced BESS Solutions
ONESUN's solutions in the BESS field are particularly outstanding. Its Smart BESS system not only supports grid-connected and off-grid switching but also features black start, island operation, and three-phase load imbalance handling capabilities, with remote monitoring and intelligent operation enabled through a cloud platform. This highly integrated and intelligent system design provides customers with higher operational efficiency and lower maintenance costs.

In summary, ONESUN not only represents the leading level of Chinese energy storage manufacturing but also serves as a trustworthy partner in the context of global energy transition. For enterprises seeking to establish lithium battery manufacturing capabilities in emerging markets like Brazil and gradually achieve localized R&D and system integration, choosing ONESUN means selecting both a mature and reliable product ecosystem and a sustainable technology pathway and business model. Looking forward, as global energy storage demand continues to grow, ONESUN will continue to embrace open collaboration with global partners to jointly drive innovation and implementation in the green energy industry.
