Huawei Smart String ESS Now Available – Next-Generation Energy Storage for Utility & C&I

BayWa r.e. Solar Systems SIA proudly introduces the Huawei Smart String Energy Storage System (ESS) – a groundbreaking solution engineered for the evolving demands of modern energy infrastructure. With increasing renewable energy penetration and the growing need for grid stability, Smart String ESS delivers unmatched safety, scalability, and operational intelligence.

 

A New Standard in Utility-Scale & Commercial Energy Storage

Huawei Smart String ESS combines innovative architecture with advanced software-driven control to offer:

 

More Usable Energy & Higher Yield

Thanks to pack- and rack-level optimization, the system ensures maximum usable energy and improved revenue performance.

 

Optimized CAPEX & Lower LCOS

Prefabricated, modular design supports pallet-based transport, quick installation, and seamless capacity expansion—reducing Levelized Cost of Storage by up to 20%.

 

Industry-Leading Safety Architecture

The Smart String ESS features Huawei’s multi-layer “4+2” proactive safety system, including cell-level monitoring, liquid cooling, and a dual fire-suppression strategy (NOVEC™ 1230 + sprinkler system). This ensures maximum protection and long-term reliability.

 

Advanced Grid-Forming Capabilities

The system supports black start, fast frequency regulation, spinning reserve, and hybrid PV+ESS operation—making it suitable for complex grid environments and large-scale renewable integration.

 

Smart O&M and Automatic SOC Calibration

Cloud-based diagnostics, AI-driven performance analysis, and autonomous SOC calibration significantly reduce on-site maintenance and improve operational efficiency.

Designed for Every Large-Scale Scenario

Smart String ESS is available in a range of configurations from 1 MWh to 5 MWh, paired with high-efficiency Smart PCS modules achieving up to 99% conversion efficiency. These solutions are ideal for:

• Utility-scale PV + ESS plants
