SAJ Anticipates Significant Growth in Energy Storage Market with Strategic Product Innovations

The commercial and industrial (C&I) market for energy storage is expected to maintain an impressive growth rate of 30% to 50% over the next three to five years, according to Samil Ouyang, CEO of Sanjing (SAJ). In an interview, he shared insights on the global outlook for energy storage systems by 2025 and the evolution of SAJ’s product line.

Outlook for Energy Storage Systems

Ouyang: The global C&I market is thriving, with a projected growth rate of 30% to 50% in the coming years. Although battery energy storage systems (BESS) currently hold a relatively small share of the global market, we are witnessing positive trends across regions including China, the United States, Australia, and Europe, as well as in Asia, Africa, and Latin America.

Recent adjustments in component prices have led to a steady annual growth of 20% to 30% in the residential market in Asia, Africa, and Latin America. In contrast, Europe’s residential market may experience stability or a slight decline this year due to inventory destocking, but is expected to stabilize and possibly see a slight increase by 2026. The US residential energy storage market is viewed positively, bolstered by decreasing interest rates and supportive policies. Meanwhile, Australia is beginning to recover from previous lows, and Southeast Asian markets such as Vietnam, the Philippines, and Thailand are also on an upward trajectory. Notably, there is considerable demand for rechargeable energy storage systems (RESS) in the Middle East and North Africa, particularly in war-affected areas like Israel, Lebanon, and Iraq.

Evolution of SAJ

Ouyang: As we celebrate SAJ’s 20th anniversary in 2025, we reflect on our journey. SAJ began by manufacturing frequency converters in 2005, entered the PV inverter market in 2011, and started producing low-voltage residential storage inverters in 2015. In 2018, we launched our first residential all-in-one solution, an AC-coupled energy storage system. By 2024, we had expanded operations to over 85 countries, focusing on localizing our production capabilities.

Our core values—customer orientation, technological innovation, pursuit of excellence, and openness—drive our success. We believe that a company’s long-term vitality is rooted in its culture. Our partnerships with leading customers have kept us attuned to industry trends. For instance, through collaboration with OSW in Australia, we gained insights into dynamic anti-islanding requirements and the demand for IoT software innovation. Similarly, working with Soollar allowed us to tailor products for the Brazilian market. Our R&D departments adopt an open and inclusive approach, enabling us to deliver high-quality solutions.

Product Line Evolution

Ouyang: In 2025, SAJ plans to enhance its residential energy storage offerings and expand its small C&I product line. We will introduce high-end DCDC all-in-one residential products, integrating our AI-driven elekeeper energy management system, catering to the needs of the European, American, and Australian markets. In contrast, we aim to provide split-type low-voltage products in Asia, Africa, and Latin America, where backup power and cost-effectiveness are crucial.

For the small C&I sector, we will continue to offer integrated and split-type hybrid DC-coupled products, including 50 kW/100 kWh models to meet integrated photovoltaic, energy storage, and charging requirements, alongside 125 kW/261 kWh integrated AC-coupled products for various energy storage scenarios.

Market Focus and Expansion Plans

Ouyang: Currently, we are concentrating on markets in Asia, Africa, and Latin America, particularly in Brazil, Pakistan, Vietnam, Thailand, and South Africa. In Europe, our focus includes Germany, Italy, Spain, the Netherlands, Belgium, Sweden, Ireland, the UK, Poland, and Romania. In the US and India, we are collaborating with local brands. Our low-voltage energy storage and all-in-one products for the C&I market are designed to address the needs in Brazil, Pakistan, and South Africa, and our expansion will also target Malaysia, the Philippines, Indonesia, Mexico, Colombia, Zimbabwe, Kenya, Nigeria, Egypt, Turkey, and the UAE.
