With the rapid growth of global demand for commercial and industrial (C&I) energy storage systems, GSL ENERGY has officially lauched a new generation of all-in-one C&I Energy Storage Systems (C&I ESS). This comprehensive product release further strengthens GSL ENERGY’s portfolio in the C&I energy storage market and expands system flexibility across a wide range of application scenarios.

The newly released product lineup integrates both liquid-cooling and air-cooling technologies, enabling broader power and capacity configurations. These systems are designed to meet diverse deployment requirements across industrial parks, manufacturing facilities, commercial complexes, and distributed energy systems.

New All-in-One C&I Energy Storage Prodyct Lineup

The newly launched C&I ESS mdels include:

GSL-BESS125K418 Liquid-Cooling All-in-One ESS

GSL-BESS125K261 Liquid-Cooling All-in-One ESS

GSL-BESS80K261 Liquid-Cooling All-in-One ESS

GSL-BESS125K241 Air-Cooling All-in-One ESS

GSL-BESS125K215 Air-Cooling All-in-One ESS

These systems cover a power range of 80kWh-125kW and a capacity range of 215kWh-418kWh, allowing flexible selection and project-level customization. They are suitable for typical C&I energy storage applications, including:

Peak shaving and valley filling

Demand charge management

PV plus energy storage integration

Backup power and energy resilience

Core Highlight 1: Self-Developed High-Voltage BMS Redefines System-Level Compatibility

At the core of this new product release is GSL ENERGY’s self-developed high-voltage Battery MAnagement System (BMS), which delivers enhanced system compatibility, safety, and scalability for C&I energy storage systems.

Key Technical Advantages of GSL HIgh-Voltage BMS

• Ultra-Wide Voltage Platform:
  100–1000Vdc high-voltage architecture, supporting both current and future C&I energy storage system requirements.
• Multiple Current Options:
  Available in 100A, 200A, and 300A, enabling flexible system matching across different power levels.
• Advanced Safety and Management:
  Cell-level monitoring and balancing, high-precision SOC and SOH algorithms, and multiple active protection mechanisms ensure stable and reliable system operation.

Rather than being designed for gingle-product compatibility, this high-voltage BMS is built with platformization, engineering robustness, and long-term evolution in mind — prociding a solid foundation for long-term performance and return on investment in C&I energy storage projects.

Core HIghlight 2: Multi-Brand Inverter Compatibility Enables Ture Plug-and-Play Deployment

GSL ENERGY’ s high-voltage BMS has completed system-level integration and joint commissioning with the Solis C&I energy storage inverter platform. In addition, it has achieved verified compatibility with multiple mainstream 125kVA C&I inverter brands, including:

• Deye
• Solis
• Fox ESS
• Solinteg
• Inhenergy

Through deep integration of BMS-PCS communication protocols and physical joint testing, GSL ensures system consistency in gird connection control, power response, protection logic, and operational strategies. This significantly reduces integration risks and shortens project delivery timelines.

Compatibility, in this case, goes beyond parameter matching — it represents full system-level verification, which forms a key competitive advantage of GSL’s high-voltage BMS.

Core HIghlight 3: Dual Cooling Technology for Flexible C&I Energy Storage Deployment

LIquid-Cooling All-in-One ESS

• Precise temperature control improves battery cell consistency
• Ideal for high-temperature, high-load, and long-lifespan applications
• Higher system efficiency and enhanced life-cycle value

Air-Cooling All-in-One ESS

• Proven and mature system structure
• Easy maintenance and cost-effective deployment
• Suitable for standardized C&I energy storage projects requiring fast installation

By leveraging a unified high-voltage BMS platform, GSL ENERGY delivers consistent control logic and operational experience across both cooling architectures. This allows customers to select the most suitable system configuration based on project requirements, without being limited by system compatibility.

Building Long-Term, Scalable C&I Energy Storage Systems Centered on BMS Technology

From battery cell selection and system architecture to hardware design and software algorithms, GSL ENERGY continues to follow its strategy of self-developed core technologies. The launch of multiple new C&I ESS products represents not only an expansion of the product portfolio but also a demonstration of the platform-level capabilities of GSL’s high-voltage BMS.

Looking ahead, GSL ENERGY will continue strengthening technical collaboration with global PCS manufacturers, driving the evolution of commercial and industrial energy storage systems toward greater safety, efficiency, ease of integration, and long-term value creation.
