Rongxin Technology has officially launched a new product with a capacity of 522kWh, aimed at addressing significant challenges in the energy storage sector. This announcement was made on October 15, 2025, at the SNEC ES+ 11th International Energy Storage Conference held in Shanghai. The company is focusing on three primary advantages of the new product: high energy density, intelligent high-efficiency operation and maintenance, and enhanced safety and protection measures.
The 522kWh energy storage system features an energy density greater than 200kWh/m², requiring a floor area of only 15m² for a 1MWh system. This compact footprint allows for more efficient use of space. Additionally, Rongxin Technology has indicated that the cost of electricity for the new product is 5% lower than that of its first-generation products, with maintenance expenses reduced by 50%.
With a payback period of just 2 years for investors, the new product is designed to be highly competitive in the market. It is expected to be a leader in energy storage solutions, especially with its lower manufacturing costs and enhanced safety features. The system has achieved a stability rating of 5.5T for load-bearing capacity and is capable of withstanding extreme weather conditions.
The product integrates an advanced BMS (Battery Management System) and LEMS (Local Energy Management System) to ensure optimal performance and safety. These systems work together to provide real-time monitoring and management of the energy storage system, enhancing its reliability.
Rongxin Technology’s new energy storage system is designed for various applications, including industrial, commercial, and residential use. It supports N+1 redundancy configurations, which enhance its reliability and adaptability to different operational demands.
In conclusion, the launch of the 522kWh energy storage system by Rongxin Technology marks a significant advancement in the energy storage industry. With its focus on high performance, cost efficiency, and safety, the new product is set to meet the growing demands of energy storage applications worldwide.
