PCS exports to Europe and North America need to meet different EMC standards, resulting in some differences. The main differences are:
1. Europe: Follows the EMC directives for CE certification (2014/30/EU). Key harmonized standards include: emission standards EN 61000-6-3/4 (general) or EN 61800-3 (regular electric drive systems), and immunity standards EN 61000-6-1/2. For photovoltaic inverters, EN 62109 is a safety standard but also involves EMC.
2. North America: Primarily involves FCC Part 15 Subpart B (intentional radiators, corresponding to conducted and radiated emissions) and CISPR 11 (corresponding to ANSI C63.4 test method). Regarding immunity, IEC standards or industry standards (such as UL 1741) are typically referenced. Differences: Limits may differ (e.g., FCC Class A/B vs. CISPR 11 Class A/B); testing method details may differ; Europe mandates the CE marking, while North American FCC uses a Declaration of Conformity (DoC) or Certification. Companies need to select the appropriate standard for testing and certification based on their target market.
