SGS Awards IEEE 693 High-Performance Seismic Qualification Certificate to Hoymiles Power Converter
Against the backdrop of accelerating global energy transition, the application scale of energy storage systems in the power grid continues to expand, making them a critical infrastructure supporting high-proportion grid integration of renewable energy. In this process, the safety and reliability of energy storage power stations have increasingly become a focus of industry attention, especially in earthquake-prone regions, where the seismic resilience of power equipment directly impacts the stable operation of energy systems and asset safety. Driven by this, domestic and international markets have raised higher requirements for the operational capability of energy storage equipment under extreme conditions in recent years. International standards, including IEEE 693, are widely used to evaluate the performance of power equipment in seismic environments and have gradually become one of the key technical thresholds for energy storage products entering overseas markets.
In this collaboration, SGS conducted a high-performance level (HPL) seismic simulation assessment on Hoymiles’ HPCS3500-E series energy storage power converter in accordance with the IEEE 693-2018 standard. The results indicate that the structural stability of the product under simulated seismic conditions meets the requirements of the relevant standard, verifying its ability to operate under high-intensity seismic scenarios. This compliance validation reflects Hoymiles’ comprehensive technical capabilities in the structural design and safety protection of energy storage power converters. On one hand, through high-performance level seismic simulation verification, the reliability of the equipment in extreme environments such as earthquakes is enhanced, helping to reduce the risk of system failure and potential asset losses. On the other hand, the product’s strict adherence to the IEEE 693-2018 standard provides important technical basis and compliance support for its application in international markets. Additionally, this achievement demonstrates that the company has reached a high level in structural design, stress analysis, and system reliability.
As an internationally recognized testing, inspection, and certification organization, SGS has developed technical service capabilities in the energy sector covering design verification, simulation analysis, and testing certification. This project verified the seismic performance of the product through professional methods, providing technical support for overall equipment reliability assessment and offering a basis for its engineering application under complex operating conditions. Furthermore, this practice provides a reference for technical research, design optimization, and engineering application related to high-standard seismic capabilities of energy storage equipment.
