Solar Array Simulation (SAS) Software Option
Solar inverter designers need to verify their inverter is capable of delivering the maximum power available from solar modules. The I-V curve of solar cells can be
influenced by various weather conditions such as a cloudy day. Combined with the SAS application software, PVS users can easily simulate the I-V curve of different
arrays under various irradiance conditions while measuring and validating the effectiveness of the inverter’s MPPT algorithm.
Features
■ Variety of input parameters
(Voc/Isc/Vmp/Imp/FF/FFv/FFi)
■ Monitors and logs real-time voltage,
current, power, MPPT efficiency, and average
MPPT efficiency
■ Simulate I-V curve under different weather
conditions during a day
■ User-definable irradiance profile
■ Generate a custom I-V curve with up to
1,024 data points
■ Test to EN50530 and Sandia Labs standards
PV Simulation
Solar arrays consist of multiple solar cells characterized by a complex voltage and current profile that is represented in an I-V curve.
Generate an I-V curve
manually via a 1,024-point
voltage and current table
with Notepad or MS Excel
and load it in the software.
Automatically generate the I-V curve
of a solar array in the software by
specifying open circuit voltage (Voc),
short circuit current (Isc), maximum
power voltage (Vmp), and maximum
power current (Imp) along with fill
factor parameters.
PV simulation curve
The PVS power supply outputs points on the I-V curve in 1 ms
intervals to test the inverter’s MPPT efficiency.
Use any of the software’s built-in
irradiance profiles or generate your
own point-by-point irradiance
profile.
