Scope

GB 47740-2026 is the English-translated version of 光伏组件铭牌标识要求.

GB 47740-2026 is the Chinese national standard covering what must be on the nameplate of a PV module - the electrical ratings at standard test conditions, the system voltage and fuse rating, the class and the safety markings, the manufacturer and the traceable serial number. The nameplate is what an installer sizes a string from and what an inspector checks against. Mandatory, first edition, in force from 1 June 2027, with the module safety standard GB 47739-2026. It was issued on 25 May 2026 and takes effect on 1 June 2027, as a first edition. The document is under the responsibility of the Ministry of Industry and Information Technology. This page is published from the official record of the 2026 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.
