The Anker SOLIX X1 Energy Storage System has achieved a key milestone in safety recognition, earning four key certifications from the CSA Group, a respected leader in safety, health, and sustainability.

These certifications – UL 9540, UL 9540A, UL 1741, and UL 1973 – demonstrate the Anker SOLIX X1’s compliance with rigorous North American safety standards for energy storage systems.

CSA Group’s certifications are widely recognized in North America, signifying a product’s adherence to stringent safety protocols. The CSA certifications include:

  • UL 9540 focuses on safe installation, operation, and integration with buildings and power systems. It requires a comprehensive safety review including fire protection, electrical safety, and environmental considerations. UL 9540 is a globally recognized standard for energy storage systems.
  • UL 9540A dives deeper into the specific safety of the battery modules, packs, and overall system, examining performance under normal and emergency conditions. This includes thermal management, electrical safety, and chemical safety. UL 9540A also factors in how the system responds to battery failure scenarios like thermal runaway.
  • UL 1973 puts the battery through its paces with a range of tests, including simulating extreme temperatures, overcharging, and over-discharging to ensure safe operation in various environments.
  • UL 1741 examines the safety and performance of the inverters, converters, and controllers that manage power flow within the system. This standard is relevant for integrating the Anker SOLIX X1 with solar photovoltaic systems.
