Products Description
The 50KW Energy Storage System (ESS) is built around GoodWe's GW50K-ET-10 three-phase hybrid inverter, tailored specifically for commercial and industrial (C&I) photovoltaic (PV) installations. It integrates high-efficiency power conversion, flexible energy management, and reliable backup capabilities, supporting both on-grid and off-grid operations. When paired with a Static Transfer Switch (STS) Box and compatible lithium-ion batteries (e.g., GoodWe Lynx C), the system delivers a comprehensive, scalable energy storage solution that balances power supply stability, cost optimization, and environmental sustainability.

Core Advantages
Flexible & Adaptable Operation
Supports parallel connection in both on-grid and off-grid modes, easily expanding system capacity to meet growing energy demands.
High Efficiency & Powerful Performance
Boasts a maximum efficiency of 98.1% and European efficiency of 97.5%, minimizing energy loss during conversion.
Smart Control & Reliable Backup
Enables UPS-level switching (requires additional STS Box) for seamless transition to backup mode during grid outages, ensuring uninterrupted power supply for critical loads.
Robust Safety & Wide Compatibility
Features an IP66 ingress protection rating and operates in a wide temperature range of -35~+60℃, suitable for harsh outdoor environments.
