UL 9540 OUTLINE
UL Standard for Safety Outline of Investigation for Energy Storage Systems and Equipment
|Publication Date:||30 June 2014|
These requirements cover energy storage systems that are intended to store energy from power or other sources and provide electrical or other types of energy to loads or power conversion equipment. The energy storage systems may include equipment for charging, discharging, control, protection, communication, controlling the system environment, fuel or other fluid movement and containment, etc. The system may contain other ancillary equipment related to the functioning of the energy storage system.
These systems may be used in systems that are standalone to provide energy for local loads, in parallel with an electric power system, electric utility grid or applications that perform multiple operational modes.
These are intended for use in utility-interactive applications in compliance with the Standard for Interconnecting Distributed Resources with Electric Power Systems, IEEE 1547 and the Standard for Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems, IEEE 1547.1 or other applications intended to provide grid support functionality.
The energy storage systems are to be installed in accordance with the national and local electrical codes and other applicable codes. This outline assumes that the final installation of the energy storage system will be performed by qualified service personnel in accordance with the applicable installation instructions, installation practices and national installation codes. Energy storage systems are intended for installation subject to approval by the Authority Having Jurisdiction.
