Technical requirements for residential photovoltaic and energy storage integrated systems

1 Scope

GB/T 46898-2025 is the Chinese national standard covering the box on the wall of a house with solar panels and a battery - inverter, charger and battery management in one unit, with its efficiency, its grid connection and protection, its behaviour when the grid fails and its safety around a lithium battery inside a home. First edition, 21,500 words. It was issued on 31 December 2025 and has been in force since 1 April 2026, as a first edition. The document is under the responsibility of the China Electricity Council. 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 specifies the classification and coding of residential photovoltaic and energy storage integrated machines, their normal operating conditions, appearance and protection level, basic functions, and electrical characteristics. Requirements include energy efficiency, safety performance, electromagnetic compatibility, environmental adaptability, testing rules, marking, packaging, transportation, and storage. This document applies to the design and manufacture of single-phase or three-phase residential photovoltaic and energy storage integrated systems connected to the power grid at 220V/380V voltage levels. Testing, inspection, operation, maintenance and repair.
