Technical Insights | Clarify the boundary between IEC 62477-1 and IEC 62109 standards to empower global compliance of optical storage products

2026-03-10
In the wave of global energy transition, photovoltaic and energy storage equipment are entering thousands of households and large power plants at an unprecedented speed. The safety and compliance of power electronic converters, the core of these devices, has become the key for enterprises to go global. But when faced with the two major standards IEC 62477-1 and IEC 62109, many people are easily confused: what are the differences between them? How should we choose?
01 Standard positioning
62477-1: General horizontal safety standard covering the basic safety requirements of all power electronic conversion equipment.
62109-1/-2: Photovoltaic special standards, which strengthen the special requirements of photovoltaic scenarios on the basis of general terms.
02 Applicable scenario judgment method
Pure photovoltaic equipment (such as grid connected inverters): with 62109 as the core.
Integrated photovoltaic and energy storage equipment: simultaneously meets the requirements of 62477-1 and 62109.
Pure energy storage equipment: centered around 62477-1.
03 Exclusive Key Points for Photovoltaic Scenarios
Anti islanding protection: Grid connected equipment must be equipped to ensure the safety of the power grid and personnel.
Outdoor environmental reliability: testing for salt spray, enclosure protection level, light attenuation, etc.
Photovoltaic specific fault protection: safety mechanisms such as residual current and grounding insulation impedance monitoring.
04 Collaborative Relationship and Implementation
62477-1 provides a globally universal baseline certification pathway.
62109 provides the official "pass" for photovoltaic scenarios, which is based on EN 62109 in Europe and usually corresponds to GB/T 37409 in China.
In case of conflict, priority shall be given to implementing the photovoltaic special provisions; Overall, the two form a combination of "universal baseline+specialized reinforcement".
Key points of version 05
62477-1: 2012/2022 version evolution, comparison between international and EU versions.
62109-1/-2: The international version of 2010/2011 corresponds to EN 62109-1/2 in the European Union.
06 Core Conclusion
To ensure reliable compliance in the global market, it is necessary to clarify the input source during the design phase and establish a dual track design concept of "universal baseline+photovoltaic special" to ensure smooth certification paths in different regions.
Practical Implementation Checklist
Specific steps for landing
1. Define input sources and system boundaries
Clarify whether the equipment is pure photovoltaic, photovoltaic+energy storage integrated, or pure energy storage, and determine the standard set that needs to be covered.
2. Set design goals and compliance matrix
Using the general baseline of 62477-1 as the baseline, supplement the photovoltaic specific clause of 62109-1/2; Clear conflict priority (photovoltaic scenario priority).
3. Conduct risk assessment and design evaluation
Conduct risk assessment and design verification on key points such as anti islanding, outdoor environment, and fault protection during the initial design phase.
4. Plan testing and validation scheme
Arrange a phased verification plan based on the general test of 62477-1 and the photovoltaic specific test of 62109.
5. Preparation of Technical Documents and Compliance Evidence
Summarize design specifications, risk assessments, test reports, and traceability documents to ensure that certification bodies can quickly review them.
6. Choose the appropriate authentication path
Based on the target market, select the corresponding certification system (such as CE, UL, T Ü V, etc.) and connect with regional versions (EN, GB/T correspondence).
7. Design traceable testing circuits
Establish a traceable chain from design input to test output to ensure that subsequent changes are controllable and compliant.
Develop phased launch strategies for different markets
Prioritize the certification of high priority markets and gradually expand to other regions to reduce risks and costs.
