GoodWe ESA 125kW/261kWh

The GoodWe ESA Series 125kW/261kWh is a fully integrated commercial and industrial (C&I) energy storage system designed for flexible, high-performance energy management applications. Combining a 125kW power conversion system with 261kWh of LFP battery storage in a compact cabinet, the ESA Series delivers reliable backup power, peak shaving, load shifting, and energy optimisation for commercial facilities, industrial operations, and hybrid solar-plus-storage projects.

Engineered with GoodWe’s self-developed PCS, BMS, and EMS architecture, the ESA Series offers intelligent “3S” coordination for seamless system performance, advanced battery management, and smart energy control. The system also features AI-driven battery diagnostics and health prediction to improve operational reliability and long-term asset management.

Its highly integrated cabinet design simplifies transportation, installation, and commissioning, while supporting the scalable deployment of up to 20 units in parallel, enabling systems with capacities of up to 2.5MW / 5.22 MWh.
