In a conference room in S ã o Paulo, Brazil, two heavy agreements were solemnly signed. This is not an ordinary business handshake, but the beginning of a cooperation that is about to light up the green energy landscape in multiple corners of the world.

On December 10, 2025, Dongfang Risheng New Energy Co., Ltd., a leading enterprise in the field of photovoltaics and energy storage in China, and WEG, a Brazilian industrial giant with operations in over 140 countries worldwide, jointly announced that they had officially signed a strategic cooperation agreement for an energy storage system with a total capacity of up to 3GWh. This order is like a giant rock thrown into Jinghu, with ripples spreading from South America to North America, Europe, Africa, and even Australia.

From photovoltaic partners to energy storage allies

This cooperation is a comprehensive upgrade and deepening of the long-term close cooperation between Dongfang Risheng and WEG in the field of photovoltaics. According to the agreement, Dongfang Risheng will provide advanced large-scale and industrial energy storage system solutions for WEG between 2026 and 2028. WEG, as an internationally renowned enterprise with a deep foundation in the fields of renewable energy, industrial energy efficiency, and smart grids, is actively expanding its energy storage and comprehensive energy services. The selection of Dongfang Risheng as the core partner this time is precisely due to its deep accumulation and full industry chain capabilities in the field of lithium batteries and energy storage for 20 years. From photovoltaics to energy storage, the partnership between the two sides has made a crucial leap, jointly aiming for the grand goal of optimizing the global energy structure and transitioning to green and low-carbon.

The confidence of self-developed full stack and dual security certification

The key to Dongfang Risheng winning such a large international order lies in its technological strength and safety standards. The company has the full industry chain capability integrating research and development, production, sales, and service. Its products cover core links such as energy storage converters (PCS), battery management systems (BMS), energy management systems (EMS), and battery systems. It is particularly worth mentioning that the energy storage system built on its independently developed "4S deep integration technology" can be flexibly applied to various complex scenarios such as renewable energy grid connection, grid peak and frequency regulation, emergency power supply, and microgrid. On the lifeline of the safety industry, Dongfang Risheng's energy storage battery system has taken the lead in China to obtain both China's authoritative certification and the US UL 9540A safety certification. This dual high standard certification provides the toughest "passport" and "trust certificate" for its products to be marketed globally.

Green mission with business coverage in over 90 countries

The signing of the 3GWh agreement marks a new stage of globalization for Dongfang Risheng's energy storage business. According to the plan, these energy storage systems will support WEG's projects in multiple regions including North and South America, Europe, Africa, and Australia. This is closely linked to its existing global footprint: from bringing stable electricity to remote villages in South America, to assisting in the energy transformation of the North American Industrial Park; From supporting European households to increase energy self-sufficiency, to empowering off grid communities in Africa to build green microgrids, Oriental Sunrise's business has spread to over 90 countries and regions worldwide.

In the future, the company will continue to work with global partners such as WEG to promote the implementation of safe, reliable, and fully self-developed optical storage integration solutions in more regions and scenarios around the world, accelerating the construction of efficient, resilient, and sustainable new energy systems.Editor/Yang Meiling
