Energy Storage Systems

ICC CEUs - 0.45 - This 5-module course, is based on UL 9540, UL 9540A, the 2018 and 2021 International Fire Code (IFC) , the 2018 and 2021 International Residential Code (IRC) , and the 2020 National Electrical Code (NEC). The course explains some of the key items and requirements of UL 9540 and 9540A. It also explains how the 2018 IFC references the UL 9540 and 9540A standards and explains other important battery requirements of the IFC. Important items of Article 706 of the 2020 NEC are also covered. The last portion of the class covers a variety of line diagrams and manufacturer specification sheets for some common battery backup systems that the industry is currently seeing installed. Each module consists of an integrated video presentation, including presentation slides, explanation, and examples. Modules are designed to be roughly 25-40 min. in length. 

Course Objectives:

  • Understand the importance of UL 9540 and 9540A in relation to energy storage systems (ESS).
  • Understand the basics of UL 9540A for large-scale fire testing.
  • Know the differences between “threshold quantities” versus “maximum allowable quantities” per the IFC.
  • Determine ESS quantities allowed inside and outside of a building.
  • Separation of battery arrays and battery units.
  • Proper locations and capacity limits of ESS for residential use.
  • Required disconnects and overcurrent protection for ESS.
