T/CEEIA 348-2019 Certification Specifications for Residential Rooftop Photovoltaic Systems

Scope

Scope: 1.1. This standard applies to residential rooftop photovoltaic systems. This standard specifies the certification requirements, certification evaluation methods, and certification results for residential rooftop photovoltaic systems in seven aspects: general requirements, load safety, fire safety, electrical safety, electromagnetic compatibility, lightning protection and grounding, and functionality and performance. This standard applies to certification bodies conducting certification activities for residential rooftop photovoltaic systems and to installers organizing and standardizing their service activities. This standard applies to certification activities for buildings with a construction area of no more than 500m2, where the load-bearing structure is made of concrete, steel, masonry, or wood, and that consider adding residential rooftop photovoltaic systems. This standard establishes the principles of electric shock protection for residential photovoltaic system certification. Based on the voltage level limits defined in Zone I of GB/T 18379 "Voltage Segments for Electrical Installations in Buildings" as stipulated in GB 3805 "Ultra-Low Voltage (ELV) Limits", it provides requirements, test methods, and judgment criteria for preventing contact with dangerous live parts, ensuring safe grounding protection, matching load requirements for wiring interconnections, and implementing fault protection in residential rooftop photovoltaic systems. 1.2. This standard does not apply to residential rooftop photovoltaic systems. This standard does not apply to certification activities for concentrator-type residential rooftop photovoltaic systems or building-integrated photovoltaic power generation systems. This standard does not apply to certification activities for residential rooftop photovoltaic systems composed of multiple energy sources. This standard does not apply to certification activities for residential rooftop photovoltaic systems with
