Stay on the curve to accurately test solar array inverters

Posted by Bill Martin on Apr 29, 2015 9:28:33 AM

In order to perform an accurate test of solar array inverters, the output of a solar array simulator must faithfully follow the I-V curve of a solar array or solar panel. That is to say that it must respond just as a solar array would to the changing load conditions imposed by the inverter under test. In order to evaluate how well a simulator can do this, you need to consider three parameters: output noise current, phase error between output voltage and current, and the maximum power point (MPP) tracking accuracy.
