Suntech’s SunStorage PRO STE-1ML-500P integrated liquid-cooled energy storage container is set to make its debut in the Ukrainian market, the milestone coming as energy storage takes on an increasingly important role in strengthening energy resilience, with solar-storage integration offering a way to better coordinate renewable generation, energy storage and power supply flexibility.
The Ukrainian government has this year established a dedicated 100MW support quota for solar power plants combined with energy storage systems, further highlighting the growing role of energy storage in the country’s evolving power system.
Against this backdrop, the introduction of the SunStorage PRO STE-1ML-500P marks a further step in Suntech’s expansion of its energy storage business across Europe, the integrated solution designed to support flexible power supply under different operating conditions.
The product is a 10-foot integrated energy storage system that combines battery system, liquid cooling system, fire protection system, an STS grid-connected/off-grid switching unit and AC combiner cabinet in a single containerized solution.
By combining grid-connected operation with fast off-grid switching, the STE-1ML-500P provides greater flexibility for sites where power continuity and energy resilience are important considerations, particularly under changing grid conditions.
The product is designed to coordinate multiple energy sources, with interfaces for photovoltaic inverters and diesel generators. PV generation, grid power, diesel generation and battery storage can be coordinated through the system’s energy management functions according to site requirements. This multi-source configuration allows the system to adapt to different power supply conditions and operating strategies, supporting applications including PV-plus-storage microgrids, commercial and industrial energy storage, backup power and remote or off-grid power supply.
The system adopts an independent battery-cluster management architecture, allowing individual battery clusters to be monitored and managed separately. This helps limit the impact of a fault in a single cluster and supports stable system operation.
Built for long-term energy storage, the STE-1ML-500P offers 1044kWh of battery-side capacity and 500kW of rated power, with up to 936kWh of available capacity. Combined with a cycle life of at least 8000 cycles, these capabilities support reliable and sustained operation across a range of energy storage applications.
