Global Solar Battery OEM/SKD Partner | Local Factory Support

In today’s global shift toward green and low‑carbon energy, photovoltaic energy storage is rapidly evolving from an “optional solution” to “essential infrastructure.” With governments worldwide rolling out renewable‑energy incentives, carbon‑neutrality targets, and electricity‑market reforms, the solar‑plus‑storage industry is entering a period of explosive growth. At this pivotal moment, ONESUN—one of the world’s leading manufacturers of solar energy storage systems and LiFePO4 (lithium iron phosphate) battery OEM/ODM solutions—is empowering partners to enter the new‑energy market through its innovative “global manufacturing + localized production” model.

Founded in 2014, ONESUN is an integrated energy manufacturer specializing in batteries, inverters, and energy‑storage systems. Its products are exported to more than 70 countries, with cumulative project deployments exceeding 3GW, demonstrating strong global delivery and service capabilities. Leveraging its mature manufacturing system and deep technical expertise, ONESUN is now recruiting global partners to jointly advance its “90‑Day Factory Program.”

Through SKD/CKD assembly models, partners can achieve localized production, localized sales, and localized service, enabling rapid entry into the renewable‑energy sector.

Why is now the best time to join ONESUN? From a policy perspective, more and more countries are accelerating the adoption of solar‑plus‑storage solutions. Rising electricity prices, diesel‑replacement needs, and unstable power grids are driving surging demand for energy storage. Across Africa, Southeast Asia, the Middle East, and Latin America, off‑grid and weak‑grid environments rely heavily on storage systems.

ONESUN has developed a portfolio of highly adaptable solutions precisely for these real‑world scenarios.

On the product side, ONESUN has built a complete energy‑storage ecosystem. Its telecom base‑station batteries (48V/51.2V) are designed for critical loads such as communication towers and data centers. The All‑in‑One ESS integrates batteries and inverters to significantly reduce installation complexity. Residential and commercial BESS solutions support flexible expansion from 10kWh to 500kWh, suitable for home storage, peak‑shaving in factories, and microgrid applications. Meanwhile, the PAYGO series enables customers in developing countries to access clean energy through affordable pay‑as‑you‑go financing.

More importantly, ONESUN provides not just products but complete end‑to‑end solutions. From cell selection and PACK design to system integration, ONESUN maintains full‑process quality control. It uses Grade‑A cells from top Chinese brands and pairs them with its self‑developed BMS to ensure safety and long cycle life. Modular system architecture allows flexible configuration based on the needs of different countries and project types.

In OEM/ODM services, ONESUN demonstrates exceptional customization capabilities. Voltage, capacity, enclosure design, communication protocols—every aspect can be tailored to customer requirements. This “component‑to‑system” customization elevates ONESUN from a traditional manufacturer to a true energy‑solution provider, offering B‑end clients practical, profitable business models.

So why do global customers choose ONESUN?

First, the dual advantage of global experience and local deployment. Through SKD/CKD manufacturing, ONESUN provides partners with complete production systems—including equipment, technical training, and quality standards—enabling rapid factory setup, reduced tariffs, and enhanced market competitiveness.

Second, stable and reliable product quality. ONESUN insists on high‑quality LiFePO4 cells, rigorous aging tests, and full‑process traceability to ensure long‑term operational reliability.

Third, a comprehensive product matrix. From telecom backup and power‑supply systems to residential and industrial storage, and from micro‑PAYGO systems to large‑scale BESS, ONESUN covers nearly all mainstream application scenarios, helping partners diversify revenue streams.

Finally, strong technical and service support. With an R&D team from top‑tier industry companies, ONESUN provides one‑stop support—from solution design to after‑sales service—delivering true turnkey solutions.

In summary, in the global race toward energy transformation, the companies that achieve localized production fastest will secure the greatest market advantage. Through its “Global OEM/SKD Partner” model, ONESUN offers partners a low‑barrier, high‑return pathway into the renewable‑energy industry. If you are seeking a reliable solar‑energy storage partner, ONESUN is undoubtedly a trustworthy choice—providing not only products but also the limitless possibilities of the future energy landscape.
