Overview

Documentation

LOWER SYSTEM COST

•Simplified architecture eliminates additional PCS, MVS and BESS-side MV cabling
•Single grid-connection point reduces grid-connection complexity and associated costs
•Pre-installed and jointly commissioned design significantly reduces on-site installation time

HIGHER SYSTEM EFFICIENCY

•Fewer energy conversions improve system RTE by 2.35% compared with MV AC-coupled solutions
•Direct storage of excess PV energy minimizes solar clipping and maximizes energy yield
•Rack-level DC/DC management improves battery utilization and discharge performance

FLEXIBLE & MODULAR DESIGN

•Modular architecture supports flexible PV and storage configurations
•Up to 100% ESS power ratio with flexible 2 to 6-hour storage duration
•Integrated DC/DC enables seamless interaction between PV and energy storage

ENHANCED SYSTEM SAFETY

•Full-link DC protection covering prevention, real-time diagnosis and active isolation
•Integrated fire protection system for enhanced PV and ESS safety
•Real-time power balancing delivers fast, precise and smooth grid-compliant output

The Sungrow DC-coupled solution seamlessly integrates PV generation and energy storage on a single platform, enabling excess solar energy to be stored before curtailment and delivered when it is needed most. With fewer power conversions, lower system investment, and higher overall efficiency, it helps maximize energy yield while improving project profitability and grid flexibility.
