UL 9540 certification is a vital safety standard for energy storage systems (ESS) and associated equipment in North America. It covers comprehensive safety aspects for the entire system, including the battery, containment, functionality, fire detection and suppression, and environmental performance. Pytes' achievement of UL 9540 certification validates the safety and reliability of its energy storage system, highlighting its compliance with industry safety standards.
WHAT DOES UL 9540 ENTAIL?
UL 9540 is a safety standard aimed at energy storage systems. For ESS connected to a utility grid, this standard includes the equipment used for the connection. It addresses fire and explosion safety concerns, covering:
Operational safety of the battery component
Fire detection
Fire propagation and suppression
Effectiveness of fire mitigation in enclosed spaces
The UL 9540 standard consolidates two other standards: UL 1973 (for the stationary battery pack) and UL 1741 (for the inverter), along with rigorous thermal and electrical testing of the components working together as a system.
WHAT DISTINGUISHES UL 9540 FROM UL 9540A?
While UL 9540 sets standards an ESS must meet, UL 9540A provides a method for evaluating thermal runaway propagation within an ESS. Although UL 9540A is not a certification, it provides critical data for manufacturers seeking UL 9540 certification, helping engineers and developers ensure their product can handle fire hazards effectively.
The UL 9540A test includes four stages:
Cell testing: Assessing flammability, thermal runaway potential, and gas composition.
Module testing: Evaluating thermal runaway propagation within modules.
Unit testing: Analyzing fire spread between units, heat release, and gas composition to assess explosion risk.
Installation testing: Testing unit-to-unit fire propagation in an enclosed space with fire mitigation equipment.
IS UL 9540 CERTIFICATION MANDATORY FOR AN ESS?
UL 9540 certification is not mandatory in most U.S. jurisdictions, but the California building code and Massachusetts have adopted it. Other states and cities may follow. Even if not mandatory, choosing UL 9540-certified systems ensures rigorous safety testing, simplifies project permitting, and identifies manufacturers committed to safety.
Pytes' residential energy storage batteries use lithium iron phosphate technology for enhanced safety. Unlike most batteries with cylindrical cells, Pytes' batteries use prismatic cells for superior performance, longevity, and safety. For example, the V5° battery, a lithium iron phosphate battery, holds 5.12 kWh and delivers 3.84 kW continuous charge/discharge (up to 5.12 kW - 1C), with a 10-year warranty covering 6000 cycles. It features a proprietary high current battery management system (BMS) for comprehensive protection, including closed-loop communication and autonomous management of charge/discharge configurations.
Pytes is one of the few UL 9540-listed lithium battery manufacturers and stands out as the most cost-effective. The Pytes V5° boasts a full range of certifications (UL 1973, UL 9540 with Sol-Ark, and UL 9540A), ensuring quicker installation and permit approval.
