SunGiga G1: technical features

The SunGiga G1 is an integrated 215 kWh battery storage cabinet based on 3.2 V – 280 Ah Lithium Iron Phosphate (LFP) prismatic cells, paired with a 100 kW Power Conversion System (PCS).

This architecture delivers an optimal balance of safety, efficiency, and operational reliability, making the system suitable for a wide range of Commercial & Industrial energy storage applications.

End-to-end validation across the entire supply chain

Jinko Solar adopts a comprehensive validation approach that extends well beyond testing the finished product. Every critical component undergoes rigorous verification, including:

• Battery cells
• Battery packs
• Battery Management System (BMS)
• Power Conversion System (PCS)
• Integrated safety systems

These tests are complemented by in-depth chemical and physical analyses of materials and microstructures, ensuring product performance and safety from the earliest stages of development.

Electrical performance and long-term stability

Dedicated laboratories test both individual battery cells and assembled battery packs, evaluating their capacity, long-term stability, and performance under varying environmental conditions.

Temperature and humidity testing replicates real-world operating environments, helping ensure long-term reliability and continuous system performance.

Advanced safety testing

To validate production quality and maximize system safety, Jinko Solar also performs a wide range of extreme and destructive tests, including:

• Short-circuit resistance testing
• Thermal runaway management verification
• Mechanical testing, including compression, impact, and nail penetration

This approach is based on the principle of redundant safety, a fundamental requirement for high-capacity battery energy storage systems.

Full-System testing under real operating conditions

Beyond individual components, Jinko Solar validates the complete energy storage system.

Its laboratories simulate real operating scenarios for both Commercial & Industrial (C&I) and utility-scale applications, evaluating:

• BMS performance in managing large numbers of battery cells
• Communication reliability
• Dynamic response to operational commands
• Alarm management
• System behavior under abnormal operating conditions

This comprehensive testing ensures reliable performance throughout the system lifecycle.

Certified quality according to international standards

The reliability of Jinko Solar BESS solutions is supported by a structured laboratory data management system that validates every test using raw measurement data.

National Chinese and internationally recognized laboratory accreditations confirm compliance with the industry’s highest quality standards and demonstrate Jinko Solar’s ability to support industrial partners in the continuous development of advanced energy storage technologies.
