IEC TR 63225:2019

IEC TR 63225:2019 highlights the problem of incompatibility of connectors for DC-application in photovoltaic systems (DC connectors) produced by different manufacturers. It addresses four particular issues in that context:

• background information on incompatibility of DC connectors from different manufacturers;
• observations and challenges concerning the handling of DC connectors from different manufacturers;
• stakeholders concerned by the incompatibility of DC connectors;
• recommendations for long-term standardization and interim measures to address incompatibility of DC connectors
