CESS-125K418 is an 8MWh-class liquid-cooled battery energy storage solution purpose-built for commercial & industrial (C&I) sites and microgrids. Designed with a hybrid on/off-grid architecture, the system can simultaneously integrate PV, utility grid, critical loads, and diesel generators, enabling coordinated multi-energy dispatch and highly reliable power delivery.

Deploying energy storage systems in cold winter regions imposes challenges that often extend beyond mere installation completion. The core difficulty lies in achieving long-term stable operation in sub-zero environments. Cold temperature can affect cell activity and charge/discharge capabilities, while also potentially introducing engineering challenges such as condensation, moisture build-up, and thermal stress differentials, placing higher demands on the thermal management and control strategies of the storage system.

As the global energy storage industry moves towards a larger scale of deployment, the North American market has emerged as a key growth area for energy storage applications. It is driven by increasing renewable energy capacity and rising demand for grid resilience. Concurrently, industry regulatory standards are continuously being elevated, making thermal safety and fire protection compliance critical thresholds for project approval and delivery.

The GSL-W20K Solar Lithium Battery Energy Storage System has successfully passed CE EMC compliance testing under EN IEC 61000-6-1:2019 and EN IEC 61000-6-3:2021 standards.
