In this guide, we demystify four leading standards- IEC 62788-1-1:2024, IEC TS 62257-9-5:2024, IEC TS 62786-2:2026, and SIST EN ISO 9806:2026, each pivotal to different aspects of solar energy engineering.
The 2026 edition of NFPA 855: Standard for the Installation of Stationary Energy Storage Systems has now been released, continuing the rapid evolution of safety requirements for battery energy storage systems (BESS).
IEC 62619: Safety standards for lithium-based batteries used in industrial applications. RoHS & REACH: Restriction of hazardous substances and chemical compliance.
UL standard 1741 lists requirements for inverters, converters, charge controllers, and interconnection system equipment for both utility-interactive (grid-tied) power systems and for non-grid-tied systems.
This Compliance Guide (CG) covers the design and construction of stationary energy storage systems (ESS), their component parts and the siting, installation, commissioning, operations, maintenance, and repair/renovation of ESS within the built environment with evaluations.
Code-Making Panel 4, responsible for solar and distributed energy resource provisions, passed its final vote in October 2024, solidifying key changes to labeling requirements, overcurrent protection device marking, cable support specifications, and energy storage.
In North America, the safety standard for energy storage systems intended to store energy from grid, renewable, or other power sources and related power conversion equipment is ANSI/CAN/UL 9540.
