Amid the sweeping global energy transition, the energy storage industry has become a core battlefield for next-generation technological competition and international collaboration. As a leading player in this field, ONESUN Technology (Shenzhen Onesun Solar Technology Co., Ltd.) leverages its deep technical expertise and global vision to build a worldwide strategic manufacturing network. By partnering with local stakeholders, ONESUN is establishing OEM and ODM joint venture factories in Africa, achieving a seamless integration of global manufacturing standards with localized production capabilities.

Founded in 2014, ONESUN is a comprehensive manufacturer specializing in photovoltaic energy storage products, lithium batteries, and inverters. The company operates multiple in-house production lines covering the entire value chain—from battery cells and Battery Management Systems (BMS) to fully integrated energy storage system design. With strong R&D capabilities and scalable manufacturing, ONESUN delivers high-performance energy solutions to customers in more than 70 countries and regions worldwide.

OEM & ODM Manufacturing Strategy Under a Globalized Layout

As global demand for high-performance energy storage systems and customized battery packs continues to rise, ONESUN has established a complete OEM (Original Equipment Manufacturing) and ODM (Original Design Manufacturing) service framework. Beyond standard battery solutions, ONESUN offers deep customization tailored to specific application scenarios, covering technical architecture, software management, system integration, and industrial design to meet diverse market requirements.

Under the OEM production model, ONESUN relies on advanced automated production lines and a strict quality management system. From battery cell inspection and PACK assembly to final product testing, the entire process is digitally traceable. All products comply with major international certifications such as UL, CE, and UN38.3, ensuring global market access and long-term reliability for brand partners.

In the ODM development model, ONESUN’s engineering team provides independent design and optimization based on customer drawings or technical specifications. This includes BMS algorithm customization, thermal management system configuration, and charge-discharge performance optimization, enabling battery systems to achieve superior stability, adaptability, and extended service life.

African Manufacturing Partnerships: ONESUN’s Global Agile Factory Plan

Recently, ONESUN achieved a strategic breakthrough in the African energy market by signing the Global Agile Factory Plan with local partners in Nigeria, South Africa, and Zimbabwe, jointly promoting the construction of OEM/ODM joint venture factories. These investments mark a significant step in ONESUN’s localized manufacturing strategy in Africa and reinforce its long-term vision of “global manufacturing, local service.”

This initiative is not merely an expansion of production capacity. Built on a standardized technology platform, the agile factory model integrates local policies, market demand, and production conditions to achieve truly localized manufacturing. As a result, supply chain cycles are shortened, logistics costs are reduced, and after-sales response times are significantly improved—enhancing the competitiveness of ONESUN’s battery products across Africa and neighboring regions.

At the signing ceremony, ONESUN’s management emphasized its commitment to working with like-minded global partners to build an efficient, flexible, and sustainable energy storage manufacturing ecosystem, jointly accelerating the development of the clean energy industry. This vision reflects ONESUN’s global mission of technological innovation and industrial upgrading, as well as its open and collaborative leadership mindset.

Customized Innovation to Meet Diverse Global Energy Needs

From residential energy storage and backup power systems to large-scale commercial and industrial energy storage, ONESUN’s product portfolio covers a wide power range—from several kilowatts to tens of kilowatts and beyond. For diverse applications such as off-grid home systems, remote telecom base station backup, marine mobile energy storage, and electric mobility battery solutions, ONESUN delivers precisely matched battery pack designs.

For example, ONESUN’s modular battery systems support flexible series and parallel configurations, allowing system designs to be optimized based on load requirements and site conditions. This ensures high scalability and system reliability. In addition, the use of high-quality LiFePO₄ cells combined with advanced thermal management technology guarantees long service life and enhanced safety, creating higher investment value for customers.

Building a Greener Future Together

Against the global backdrop of green energy development and carbon neutrality, ONESUN is not only a symbol of technical strength and manufacturing excellence but also a driving force behind the transformation of the energy storage industry. Through its leading OEM & ODM capabilities, global manufacturing network, and localized partnership strategy, ONESUN empowers customers worldwide to achieve customized, scalable, and efficient energy solutions—contributing to a greener, smarter, and more sustainable future.
