Inverter Performance Certification: Results from the Sandia Test Protocol

This paper discusses results of the work to develop a test protocol for evaluating PV inverter performance, results obtained by testing to the protocol as required by the California Energy Commission (CEC), and the use of those results to develop and evaluate inverter performance models. This paper presents preliminary results of the modeling effort, comparing the models derived from CEC data with field measurements from sample systems. In addition to predicting system performance, this model may prove equally useful in evaluating the quality of the data generated by performing the test protocol
