Wenergy’s C&I energy storage cabinets have obtained eight major certifications, including:
Combined with IP67-rated liquid cooling technology, these systems operate reliably in extreme environments ranging from –40°C to 55°C, making them well suited for factories, commercial buildings, solar-plus-storage projects, and microgrids.
Key International Certifications That Define Technical Leadership
Several core certifications highlight Wenergy’s technological depth and engineering rigor:
-
UL 9540
Recognized as the benchmark for energy storage system safety in North America, covering electrical safety, mechanical integrity, fire protection, and system-level risk control. Mandatory for entry into the U.S. and Canadian markets.
-
IEC 62933
A foundational standard for grid-connected energy storage systems, addressing full lifecycle safety management including design, installation, operation, and fault response.
-
IEC 62619
A global reference for lithium battery safety, validated through more than 30 extreme tests such as overcharge, short circuit, and nail penetration, ensuring robust safety redundancy.
In addition, Wenergy’s entire product range complies with IEC 60529 enclosure protection standards, with multiple battery cells and modules also certified under UL 1973.
Enabling Global Deployment with Confidence
Achieving broad international certification enables Wenergy to accelerate market entry across Europe, North America, Asia-Pacific, the Middle East, and Africa. More importantly, it provides customers and partners with verified assurance that Wenergy’s energy storage systems meet the highest global benchmarks for safety, reliability, and grid compatibility.
