Modular Lithium Battery Energy Storage System EN 50549 / VDE-AR-N 4105 Grid Connected Certified

Product Overview

The EN 50549 / VDE-AR-N 4105 Grid-Connected Energy Storage System is designed for battery energy storage applications requiring compliance with applicable European and German grid connection requirements.

The system can integrate lithium iron phosphate (LFP) battery technology, an intelligent Battery Management System (BMS), power conversion equipment, thermal management, and comprehensive safety protection. Its modular architecture allows flexible configuration for commercial, industrial, renewable energy, and grid-connected energy storage applications.

VDE-AR-N 4105 defines technical requirements for the connection and operation of applicable generation and storage systems on Germany's low-voltage grid. The requirements address areas including grid connection, system design, grid and system protection, operation, and verification of electrical characteristics.
