General Rules and Safety Guidelines for a Battery Energy Storage and Photovoltaic System Framework in Commercial and Industrial Installations

This paper examines the diverse functionalities of Battery Energy Storage Systems (BESS) in Commercial and Industrial (C&I) settings, particularly when integrated with Photovoltaic (PV) systems (C&I PV-BESS). While these systems provide significant benefits in energy efficiency and sustainability, they also introduce concerns regarding fire safety. To address these risks, this study reviews the associated safety hazards and conducts a comprehensive comparison of major international standards aimed at mitigating fire hazards in C&I PV-BESS installations. Additionally, the paper outlines best practices for system installation and management, focusing on key safety aspects such as cell design, module and rack construction, operational protocols, fire suppression systems, and manufacturing processes. Despite the ongoing challenge of establishing universally adopted fire prevention standards for C&I PV-BESS, this paper proposes practical guidelines to enhance safety in these installations. It also highlights innovative solutions to improve the safe operation and long-term reliability of these integrated systems.
