Sustainable BESS solutions for a greener grid  

Introducing our newest solution, JST Power Equipment’s battery energy storage systems (BESS) solutions are engineered and custom-built to meet the needs of our customers across global markets and various industry applications.  

Leveraging the JST suite of products and our advanced design and manufacturing capabilities, our modular BESS design features PCS units with robust stand-alone performance capabilities. This design simplifies the integration and control of battery energy storage systems, providing notable technical advantages in peak load management and frequency regulation within the energy storage industry. Our solutions range from 6 kV to 35 kV with a maximum stand-alone capacity of 2 MW / 4 MWh. Compatible with IEEE 1547, our solutions can be scaled to meet various applications including data centers, renewable energy (such as solar and wind), commercial buildings and industrial facilities.

Grid-Scale Battery Energy Storage System Solutions  

Battery energy storage systems designed to support large-scale energy storage are used to help balance supply and demand on electrical grids. Customers rely on these systems to store excess energy produced during periods of low demand or when renewable energy sources, like solar and wind, are generating surplus power. Our grid-scale BESS solutions range from 1 MWh to over 1,000 MWh as both traditional LV and JST’s unique HV cascade solution. They offer reliable peak power supply, energy cost optimization, maximum renewable energy utilization and continuous operation during outages.  

LV Products  

These low-voltage options include direct current battery containers and alternating current boost container. Contact us to learn more. 

HV Cascade Solution  

This high-voltage stage fed energy system uses the cascade H-bridge topology to break the battery system into pieces—only in series and not in the parallel—and can realize 35kV direct grid connection without transformer, reducing system loss and improving cycle efficiency. With the technical advantages of “three-high, two fast, one more”, it has significant technical advantages in the application fields of power generation and power grid.
