What are the requirements for energy storage systems (ESS)?

R328.1General. Energy storage systems (ESS) shall comply with the provisions of this section. 1. ESS listed and labeled in accordance with UL 9540 and marked “For use in residential dwelling units” where installed in accordance with the manufacturer’s instructions and NFPA 70. 2. ESS less than 1 kWh (3.6 megajoules).

Do energy storage systems need to be labeled?

2021 IRC Section R328.2 states: “Energy storage systems (ESS) shall be listed and labeled in accordance with UL 9540.” UL 9540-16 is the product safety standard for Energy Storage Systems and Equipment referenced in Chapter 44 of the 2021 IRC. The basic requirement for ESS marking is to be “labeled in accordance with UL 9540.”

What are the IRC requirements for energy storage systems?

There are other requirements in IRC Section R328 that are not within the scope of this bulletin. 2021 IRC Section R328.2 states: “Energy storage systems (ESS) shall be listed and labeled in accordance with UL 9540.” UL 9540-16 is the product safety standard for Energy Storage Systems and Equipment referenced in Chapter 44 of the 2021 IRC.

What is the energy storage protocol?

The protocol is serving as a resource for development of U.S. standards and has been formatted for consideration by IEC Technical Committee 120 on energy storage systems. Without this document, committees developing standards would have to start from scratch. WHAT’S NEXT FOR PERFORMANCE?

What are the goals of the energy storage safety workshop?

The goals of the workshop were to: 1) bring together all of the key stakeholders in the energy storage community, 2) share knowledge on safety validation, commissioning, and operations, and 3) identify the current gaps in understanding, managing, standardizing and validating safety in energy storage systems.

What is the maximum ESS capacity for combined locations?

The California State Fire Marshal has stated in an information bulletin that the locations can be combined for a cumulative total of 280 kWh of ESS capacity. And as we will soon discuss, code compliance for ESS in an attached garage can be much more complicated than systems in a detached garage.
