Meeting EU Compliance Standards and Strengthening Global Delivery Capability

As safety, system stability, and grid compliance become increasingly critical in the Commercial & Industrial (C&I) energy storage market, GSL ENERGY has officially announced taht its new-generation CESS-J125K261 125kW/261.2kWh Commercial & Industrial Energy Storage has successfully obtained CE EMC (Electromagnetic Compatibility) certification.

This certification confirms the product’s compliance with European market requirments and further strengthens GSL ENERGY’s capability to deliver high-power, liquid-cooled energy storage systems globally.

Compliance with EU EMC Requirments

According to official certification documents, the CESS-J125K261 C&I energy storage system has passed EMC testing under the following international standards:

• EN IEC 61000-6-2:2019 – Immunity requirements for industrial environments

• EN IEC 61000-6-4:2019 – Emission limits for industrial environments

The certification fully complies with the EU EMC Directive 2014/30/EU, verifying the system’s stable performance in complex C&I electrical environments. The system operates reliably without causing electromagnetic interference to surrounding equipment while maintaining strong immunity.

This provides solid compliance assurance for grid-connected projects, campus energy sorage deployments, and coordinated multi-device operation scenarios.
