Sunway Solar Launches 215kwh Storage System for Businesses

As energy transition accelerates and businesses face growing pressure to reduce costs while improving efficiency, the ability to flexibly manage and optimize energy usage has become critical across industries. For commercial and industrial operations, reliable power supply is not just about daily operations—it directly impacts productivity and competitive advantage.

Recognizing the limitations of traditional energy models, Sunway Solar has introduced its new 215kWh commercial and industrial energy storage system. This integrated solution combines high-power output with outdoor durability, designed to address peak demand challenges and grid instability while improving energy independence and economic performance.

The 215kWh system prioritizes performance, reliability, and ease of use through several key innovations:

The system combines battery management (BMS), energy management (EMS), modular power conversion (PCS), and fire safety systems into a single unit. This streamlined approach reduces installation complexity, minimizes footprint, and optimizes energy transfer efficiency while lowering potential failure points.

With 215kWh battery capacity and 100kW continuous charge/discharge capability, the system handles complex industrial loads—whether for backup power during outages, peak shaving during high-demand periods, or providing grid support services.

The modular architecture supports multi-unit parallel connections, allowing capacity and power expansion as business needs grow. This flexibility accommodates projects ranging from small enterprises to large industrial facilities.

The system features "black start" capability to independently power critical loads during complete grid failures. Its low-voltage direct connection simplifies grid integration while ensuring reliable operation.

Beyond core functionality, the system incorporates robust engineering for reliable operation under challenging conditions:

• Outdoor Durability: IP55-rated protection against dust and water ingress enables installation in exposed areas like building exteriors or parking lots.
• Temperature Resilience: Operates from -30°C to +55°C (-40°C to +60°C storage) with 0-100% non-condensing humidity tolerance.
• Thermal Management: Industrial-grade cooling maintains optimal battery temperatures for longevity and efficiency.
• Safety Systems: Integrated fire suppression and Class II DC surge protection provide multiple safeguards.
• High-Altitude Operation: Functions reliably up to 4,000 meters elevation.

• Battery Capacity: 215 kWh
• Voltage: 768 Vdc (720-840 Vdc range)
• Charge/Discharge Rate: ≤0.5C
• Max Power: ≤100 kW (charge/discharge)
• Dimensions: 2100×1400×1900mm
• Weight: ≤2950kg
• Communication: Ethernet/SFP with Modbus TCP protocol

This commercial energy storage system represents an advancement in industrial-scale energy solutions, enabling businesses to better manage costs, improve efficiency, and accelerate their transition toward sustainable energy models. Through continued innovation in storage technology, such systems are helping build a more resilient and efficient energy infrastructure.
