Built around LiFePO4 battery chemistry, the system is designed for applications that require stable and reliable energy storage performance. Its high-voltage architecture provides a practical solution for commercial and industrial projects requiring a compact energy storage platform with scalable capacity options.

Flexible Energy Storage for Commercial & Industrial Sites

The GSL-BESS 50K Series is designed for three-phase C&I energy storage applications, supporting a wide range of project scenarios including factories, commercial buildings, warehouses, farms, and other commercial or industrial facilities.

The system architecture supports PV string integration, AC or DC coupling, grid connection, and EMS/fleet management, allowing the battery system to be integrated into different energy management configurations according to project requirements.

With multiple energy configurations from 50kWh to 130kWh, the platform gives EPC contractors, installers, and system integrators greater flexibility when matching energy storage capacity to site requirements.

6500+ Cycle Life with LiFePO4 Battery Technology

The battery system uses LiFePO4 chemistry and provides a specified cycle life of ≥6,500 cycles under the datasheet test conditions of 25±2℃, 0.5C/0.5C, and 70% EOL.

This cycle-life specification makes the system suitable for C&I applications involving regular battery charging and discharging. The battery operating temperature range is specified as -20℃ to 55℃ for discharge and 0℃ to 55℃ for charging.

Floor-Mounted IP55 Design for Outdoor Deployment

The GSL-BESS 50K Series adopts a floor-mounted design with an IP55-rated enclosure, supporting outdoor commercial and industrial installation.

The system dimensions are 1400 × 1100 × 1650mm, excluding the inverter. This enclosure format provides a dedicated cabinet-based solution for C&I projects where organized equipment deployment and outdoor installation capability are required.

Multi-Layer Battery Safety Protection

The battery system incorporates multiple protection functions covering key operating conditions. These include:

• Short-circuit protection
• Over-current protection
• Over-charge protection
• Over-temperature protection
• Cell over-voltage protection
• Cell under-voltage protection
• Cell discharge protection

The battery system also supports BMS communication through CAN, enabling communication between the battery management system and associated equipment.

Multiple Communication Interfaces for System Integration

For monitoring and system integration, the inverter platform supports CAN, RS485, WiFi, and Ethernet communication interfaces.

The system also features an LCD, providing a local interface for system information and operational monitoring. These communication options make the platform suitable for integration with different project-level monitoring and energy management architectures.

Global Grid Compatibility

The GSL-BESS 50K Series supports a range of international grid regulations and standards, including VDE4105, IEC61727/62116, VDE0126, AS4777.2, CEI 0-21, EN50549-1, G98, G99, C10-11, UNE217002 and NBR16149/NBR16150.

The system is also specified with certifications and standards including UN38.3, IEC62619, CE, CEI 0-21, VDE-AR-N 4105 and IEC 62109. This broad standards coverage supports deployment across multiple international markets, subject to the applicable project and grid requirements.

10-Year Warranty and Parallel Expansion

The GSL-BESS 50K Series is backed by a 10-year warranty and supports multiple system configurations. The datasheet specifies up to 10 parallel connection sets for the inverter system, providing additional flexibility for projects requiring higher system capacity.
