Technical Requirements for Residential Hybrid PV and Storage Converter

This document, GB/T 46898-2025, specifies the technical requirements for residential hybrid photovoltaic and storage converters, including classification and coding, normal operating conditions, appearance and degree of protection, basic functions, electrical performance, safety performance, electromagnetic compatibility, environmental adaptability, test rules, marking, packaging, transport, and storage. It applies to single-phase or three-phase converters connected to the grid at 220V/380V voltage levels. The standard covers both grid-connected and grid-disconnected operating modes, ensuring reliable and safe power conversion between photovoltaic, storage, load, and grid interfaces. Key aspects include DC arc protection, battery management, power quality compliance, and immunity to electromagnetic disturbances. This standard is essential for design, manufacturing, testing, inspection, operation, and maintenance of residential hybrid PV storage systems, supporting the integration of renewable energy and storage in residential applications.
