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.
