GoodWe 125kW Three Phase Inverter 261kWh Commercial Battery GW125/261-ESA-LCN-G10

The GoodWe ESA Series (125kW/261kWh) is a fully integrated, all-in-one energy storage system tailored for commercial and industrial (C&I) scenarios such as industrial parks and commercial complexes.

Combining PCS, battery, EMS, and BMS in a single unit, it offers a modular and scalable design that supports flexible capacity expansion, faster installation, and simplified operation and maintenance.

• Supports up to 20 units in parallel
• (2.5MW/5.22MWh)
• AI-driven battery diagnosis and health prediction
• 3S Coordination with self-developed PCS, BMS & EMS
• Pack-level humidity monitoring with auto-dehumidification

The GoodWe ESA Series introduces a new, all-in-one Energy Storage System (ESS) tailored for a wide range of Commercial and Industrial (C&I) applications. Featuring a modular design, the ESA Series enables flexible system expansion, streamlined transportation and installation, and simplified operations and maintenance (O&M). Engineered with multi-level protection and advanced safety features-including thermal management at the cell level-the system ensures reliable performance. Its intelligent hybrid cooling approach combines air cooling at the Power Conversion System (PCS) level with smart liquid cooling for the battery modules, all within an IP54-rated enclosure suitable for outdoor environments. Equipped with integrated Energy Management System (EMS) functionality, the ESA Series supports parallel operation with grid-tied inverters for adaptable C&I deployments. Additionally, when paired with the upcoming GoodWe STS Box, it can operate in off-grid mode with grid-forming capability and Virtual Synchronous Generator (VSG) functionality.
