I. What are IEC standards and why are they important?
- IEC = International Electrotechnical Commission.
It publishes global technical benchmark standards for the electrical, electronic, battery, and PV sectors, serving as a common technical language for cross-border procurement (Source: IEC). - Standards are developed by Technical Committees (TCs): TC 82 covers solar PV energy systems; TC 120 covers grid-integrated electrical energy storage (EES);
and TC 21/SC 21A covers secondary cells and batteries (Source: IEC). - Purpose: To ensure the safety, reliability, and interoperability of components, batteries, and inverters, allowing technology developed in one market to be confidently deployed in another (Source: IEC).
- Supporting certification systems: IECEE (CB Scheme for mutual recognition of electrotechnical products) and IECRE (certification for renewable energy products);
IEC standards form the technical foundation for these certifications (Source: IEC). - Alignment with China/EU: Chinese GB standards often adopt IEC standards (e.g., GB/T 36276), and EU EN standards often adopt them identically (e.g., EN 62619);
understanding IEC standards means understanding the baseline requirements across multiple markets (Source: CNAS/Douyin Energy Storage).
II. Where to Find the List of IEC Standards (Official Channels)

Practical Application: How to Select Standards Using the Checklist
- Identify the TC/Category first: Refer to TC 82 for modules, and TC 21/SC 21A or TC 120 for energy storage batteries;
use the Dashboard to pinpoint the product’s classification (Source: IEC). - Select based on product hierarchy: Choose IEC 62619/63056 for cells, IEC 61215/61730 for modules, and IEC 62933 for system-level applications—different levels require different standards (Source: IEC).
- Check version and status: The IEC Webstore/Dashboard indicates whether a standard is Valid, Revised, or Withdrawn;
always use the current version plus the latest revision (Source: IEC). - Adopt standards based on target markets: For the EU, look for EN adoptions and battery regulations; for North America, look for UL;
for China, look for GB; use IEC as the universal baseline (Source: Douyin Energy Storage). - Use IECEE to verify laboratories: Check iecee.org for accredited laboratories and TRF templates;
select an institution that covers the target standards to avoid authorization gaps (Source: IECEE).
VII. Procurement Recommendations
- Request certificates and standard numbers from suppliers: Require IEC certificates (e.g., IEC 62619/61215/61730) including the version year and verifiable ID number;
verify model coverage via the IEC/IECEE database (Source: IEC/IECEE). - Determine the standard combination based on target markets: Ensure compliance with EN adoptions and battery regulations for the EU, UL for North America, and GB for China, while using IEC as the universal baseline before placing orders (Source: Douyin Energy Storage).
- Prioritize CB/ECEE PV certificates: A single IEC certificate can be used via the CB Scheme for multi-country market access, shortening the time-to-market and avoiding redundant testing (Source: IEC).
- Require current versions: Standards undergo revision (e.g., IEC 61215/61730 are upgrading to Edition 3);
require suppliers to specify the standard year and reject certificates based on outdated versions (Source: IEC). - Verify IECEE-recognized laboratories: Use only laboratories listed on iecee.org for testing to ensure reports are accepted by target institutions (Source: IECEE).
