Off Grid Solar Systems -Battery installation In none dwelling Zones
In Canada, energy storage systems (ESS) that are installed outside of dwelling zones do not require UL9540A certification for fire performance. Instead, these systems only require certification to CSA 22.2/UL1973, which is a standard for safety of lithium-ion battery systems.
CSA 22.2/UL1973 is a standard developed by the Canadian Standards Association (CSA) and Underwriters Laboratories (UL) for testing and certifying the safety of lithium-ion battery systems used in stationary applications, including ESS. This standard evaluates the safety of ESS components, including batteries, power electronics, and control systems, and specifies testing procedures for verifying that ESS components meet safety requirements.
For ESS installations that are not located in dwelling zones, compliance with CSA 22.2/UL1973 is typically sufficient to meet safety requirements, as specified by the Canadian Electrical Code (CEC). However, it is important to note that the requirements for ESS installations can vary depending on the specific installation and the AHJ, and it is always recommended to consult with the local AHJ to ensure compliance with all applicable codes and regulations.
