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, MR 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.

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.
The MR power supply outputs points on the I-V
curve in 1 ms intervals to test the inverter’s MPPT
efficiency.
Automatically generate PV and I-V curves by
specifying open circuit voltage (Voc), short circuit
current (Isc), maximum power voltage (Vmp),
and maximum power current (Imp) along with
temperature coefficient (ß).
PV simulation curve
Generate custom I-V curves using Excel or
Notepad to create a 4,096 point voltage and
current table. Use the SAS software to download
the I-V curve table to the power supply’s internal
memory for output.
Shadow Simulation
Use the shadow simulation mode to test solar
arrays under different weather conditions. Adjust
cloud intensity, cloud direction, and timing
parameters. Resulting PV and I-V curves are
automatically generated along with MPPT
efficiency data.
