What is PD IEC TS 63157- Quality assurance of Power conversion equipment (PCE) about?
PD IEC TS 63157 lays out recommendations for best practices for product realization, safety, customer satisfaction, and stakeholders' relationship used in the manufacture of power conversion equipment (PCE). As failures of PV systems are often reported to be caused by failures of the PCE, such as inverters and DC-DC converters, PD IEC TS 63157 aims to help the industry reduce those failures in a standardized and cost-effective way.
PD IEC TS 63157 covers manufacture of electronic PCE intended for use in terrestrial PV applications. The term PCE refers to equipment and components used for electronic power conversion of one type of electric power into another type of electric power in terms of voltage, current, and frequency.
PCE in both indoor and outdoor open-air climates as stated in IEC 60721-2-1 and IEC 60721-3-3 is covered by PD IEC TS 63157. DC-to-AC inverters, DC-to-DC converters, and battery charge converters are examples of such equipment.
Who is PD IEC TS 63157- Quality assurance of PCE for?
PD IEC TS 63157 on photovoltaic systems is useful for:
- Power conversion equipment manufacturers
- PV modules manufacturers
- PV power system manufacturers
- Certification bodies
- Auditory bodies
- Regulatory bodies
Why should you use PD IEC TS 63157- Quality assurance of PCE?
Given the high costs associated with inverter failures, it is critical to understand the root cause of component failures, methods to access or ensure dependability, and methods to anticipate the lifetime of power conversion equipment and their components through testing and quality standards.
The object of PD IEC TS 63157 is to provide more confidence in the ongoing consistency of performance and reliability of certified power conversion equipment. The requirements of PD IEC TS 63157 are developed with the assumption that the organization's quality management system has already met the requirements of ISO 9001. These guidelines also form the basis for factory audit criteria of such photovoltaic systems sites by various certifying and auditory bodies.
PD IEC TS 63157 captures key requirements customers would like to see completed to ensure high-quality products, specifically, that the products have the documented properties, including properties needed to give customer satisfaction with regard to the warranty.
