Li Ion Battery Storage System With IEEE 1547 / UL 1741 SA Grid Connected Certified

Product Overview

The IEEE 1547 / UL 1741 SA Grid-Connected Certified Energy Storage System is a lithium battery energy storage solution designed for grid-connected applications in the North American market. It is suitable for commercial, industrial, renewable energy, and distributed energy storage projects that require grid-interactive operation.

The system can integrate lithium iron phosphate (LFP) battery technology, an intelligent Battery Management System (BMS), a bidirectional power conversion system (PCS), thermal management, and comprehensive safety protection. Its modular architecture supports flexible configuration for different energy storage capacities and grid connection requirements.

IEEE 1547 establishes requirements for the interconnection and interoperability of distributed energy resources with electric power systems, including performance, abnormal-condition response, power quality, islanding, and testing requirements. IEEE 1547.9 provides additional guidance specifically for energy storage distributed energy resources.
