The compulsory standards for ESS in NFPA 855, the International Fire Code, and the California Fire Code ensure that each product meets stringent testing, design, and performance safety criteria. The cells, battery system, and power electronics are individually evaluated to their individual safety standards and then collectively evaluated as an ESS. The highest level of regulatory safety has been applied to ESS listed to these standards. This inspires the utmost confidence in the safety and performance of these systems when they are installed in accordance with these standards, the adopted fire and electrical codes, and the manufacturers installation instructions.
