电磁兼容性( EMC )指电气设备或系统运行时,对其所处的电磁环境不产生干扰或抵抗电磁环境干扰的能力。 EMC 是评价产品质量好坏的重要标准之一。为了以最为经济的方式保证产品的 EMC 质量,应该在产品设计初期采取适当的措施。根据定义， EMC 被分为电磁干扰( EMI )、电磁抗扰度或敏感度( EMS )。法规规定应满足 EMI 的最大值和 EMS 最小值。相关标准中对于可用的限值、采用的测量方法和仪器都作出了规定。

Household PV-storage-charging products integrate various power electronic devices such as photovoltaic inverters, power conversion systems (PCS), and charging modules. Their internal high-frequency switching actions (e.g., IGBT switching frequency harmonics) and complex topologies are prone to generate electromagnetic interference (EMI). Core components within such equipment (such as high-frequency switching transistors, inductors, capacitors, and control circuit boards) produce high-frequency harmonics and switching noise during operation, which may form electromagnetic disturbances through conduction or radiation paths.
With the rapid development of 5G communication technology and the Internet of Things (IoT), wireless interconnection functions of electronic devices have become widely popular in smart home appliances, leading to an increasingly complex electromagnetic environment. Household appliances (such as refrigerators, air conditioners, washing machines, etc.), due to the integration of wireless modules like Wi-Fi and Bluetooth, may not only generate high-frequency noise or conducted interference during operation but also need to resist electromagnetic radiation from mobile phone base stations and other smart devices, making their Electromagnetic Compatibility (EMC) issues increasingly prominent.
