Safely Harness Every Kilowatt-Hour of Electricity

Introducing eⁿ: The Industry’s First Matrix-Based ESS pioneers the Next Generation of Energy Storage Solutions

PET Direct Mounted Energy Storage Matrix E⁴ MATRIX-ES

The PET Direct-Mounted Energy Storage Matrix integrates power electronic battery stacks and power electronic transformers. By replacing traditional PCS and transformers with power electronic transformers, this solution significantly enhances the conversion efficiency of the energy storage system. It enables more refined battery management, establishes a safer system architecture, and provides faster grid support capabilities. This integration reduces the cost per kilowatt-hour of the energy storage system and improves the system's investment return cycle, offering a highly efficient, cost-effective solution for large-scale energy storage.
