Photovoltaic Systems - Power Conditioners - Procedure for Measuring Efficiency
|Publication Date:||1 November 1999|
|ICS Code (Solar energy engineering):||27.160|
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.
