The SAS1000 software, when paired with a DC power supply (sold separately), can accurately simulate a solar array I-V curve.

Three versions of the SAS1000 software are available depending on user requirements. Please see the table below for a comparison.

Solar-cell utilization is related to variables such as weather, season, temperature, irradiation, cloud cover, rain, snow, and other factors. Therefore, the PV inverter must have a strategy to adjust the real-time working point of a solar cell to keep it in the vicinity of the maximum power point; this process is called MPPT (Maximum Power Point Tracking). The SAS software can be used to directly simulate various real-life conditions in a laboratory test environment.

The solar industry has defined standard test patterns to match different inverter types to facilitate the research and development of MPPT performance. The SAS1000 software includes EN50530, SANDIA, NB/T32004, and CGC/GF004 test programs. Users can set their own parameters such as Vmp, Pmp, materials, test runtime, and maximum run power percentage.

This is my super awesome description for this amazing product. It includes cool features and amazing things this product is capable of! This description should be well written, short, and super helpful for the customer.
