Solar Array Simulator (SAS):

    Solar array simulation software, when used with a high-performance DC power supply, can accurately simulate the I-V curve of solar arrays. This system features precise measurements, high stability, and fast response times. With built-in parameters like Vmp (Voltage at Maximum Power) and Pmp (Power at Maximum Power), it can effectively generate the I-V curve output and produce reports. These capabilities greatly assist in testing both the static and dynamic maximum power tracking performance of photovoltaic inverters.
