Product information "GW125/261-ESA-LCN-G11 All-in-One"
The GoodWe GW125/261-ESA-LCN-G11 is a high-performance 125kW / 261kWh AC-coupled Battery Energy Storage System (BESS) engineered for commercial and industrial energy applications. Integrating the PCS, battery system, EMS, and BMS into a single outdoor-rated cabinet, the ESA Series simplifies deployment while providing reliable, intelligent energy storage and management capabilities.
Utilising proven LiFePO₄ battery technology, the system is designed to maximise safety, reliability, and operational longevity. Advanced safety features include six-layer active and passive fire protection, battery health monitoring, humidity control with automatic dehumidification, and AI-driven diagnostics for enhanced system performance.
The AC-coupled architecture allows seamless integration with existing solar PV installations and electrical infrastructure, making it ideal for energy cost reduction, peak demand management, backup power, and microgrid applications. The system is scalable, supporting up to 20 units in parallel for projects requiring up to 2.5MW / 5.22MWh of storage capacity.
With an IP54-rated enclosure, high energy density, and simplified installation requirements, the GW125/261-ESA-LCN-G11 provides a flexible and future-ready storage solution for warehouses, factories, commercial buildings, industrial parks, and other demanding C&I environments.
