 Organization: IEC Publication Date: 1 November 1999 Status: active Page Count: 26 ICS Code (Solar energy engineering): 27.160
##### scope:

This standard describes guidelines for measuring the efficiency of power conditioners used in stand-alone and utility-interactive photovoltaic systems, where the output of the power conditioner is a stable a.c. voltage of constant frequency or a stable d.c. voltage. The efficiency is calculated from a direct measurement of input and output power in the factory. An isolation transformer is included where it is applicable.
