IEC 60947-3 Amendment 2 provides information and instructions for replacement or deletion for text, terms, and definitions, for the base document IEC 60947-3:2008.

Appendix D of this document covers photovoltaic (PV) technology. As part of the answer to the challenge of sustainable development, the number of photovoltaic (PV) installations is increasing. This latest development in photovoltaic (PV) technology is challenging the conventional approach to energy sources and power distribution systems, including their operating conditions and environment. PV applications have particular characteristics and require equipment with specific performance. These performance requirements are identified for IEC 60947-3 products in this annex.
