6 FAQs about [Household energy storage test requirements]
How much energy can a residential energy storage system store?
The installation codes and standards cited require a residential ESS to be certified to UL 9540, the Standard for Energy Storage Systems and Equipment, and may also specify a maximum stored energy limitation of 20 kWh per ESS unit.
Is a lithium ion battery energy storage system certified for residential use?
The International Residential Code (IRC) and NFPA 855, Standard for the Installation of Stationary Energy Storage Systems, both have criteria for lithium-ion battery energy storage systems (ESSs) intended for use in residential applications. How can I verify that an ESS is certified for residential use?
Why is safety important for energy storage systems?
Since the beginning of energy storage system adoption, safety has remained a key pillar in the evolution of systems. We have seen the technology around residential ESS evolve and adapt to accommodate applications throughout various environments and installations.
What is the maximum energy capacity of a residential electrochemical ESS?
The current edition of UL 9540 limits the maximum energy capacity of an individual electrochemical ESS for residential use to 20 kWh (72 MJ). Currently, there is no requirement in UL 9540 for these units to be marked “Residential Use,” but such a marking has been proposed for UL 9540 for the next edition.
When is a residential use ESS included in ul 9540?
Also, due to potential confusion between other certified residential use ESSs, the marking “Residential Use” has been proposed for inclusion in UL 9540 when an electrochemical ESS complies with the unit level residential large-scale fire test performance criteria in UL 9540A.
What are the most common battery testing standards & certifications?
Below are some of the most common battery testing standards and certifications to look for when comparing home batteries. This is an overall certification for what UL calls "Energy Storage Systems" - ESS for short. A UL 9540 ESS has a UL 1973-certified battery pack (more details below) and a UL 1741-certified inverter (also more information below).
