1 Scope

GB/T 19064-2025 is the Chinese national standard covering the domestic solar system as a whole - the array, the controller, the battery and the inverter working together, the autonomy expected, the protection and the tests on the assembled system rather than on its parts. It replaces GB/T 19064-2003 after twenty-two years, in which the domestic system went from an off-grid rarity to a rooftop commonplace. It was issued on 31 December 2025 and has been in force since 1 July 2026, replacing GB/T 19064-2003. The document is under the responsibility of the Ministry of Industry and Information Technology. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document defines the terminology for off-grid residential solar photovoltaic power systems and their components, and specifies the classification and naming, technical requirements, and documentation. The document outlines the requirements for parts, markings, and packaging, and describes the corresponding test methods. This document applies to residential solar photovoltaic power systems and components, as well as other related components including solar charge/discharge controllers and DC/AC inverters. Reference for inverter functional devices and systems, such as off-grid solar photovoltaic power systems and components for solar street lights, emergency lighting equipment, etc.
