Solar array simulation control software can create curves based on three popular methods including the Sandia and EN50530 standard. The control software can vary the irradiance, simulating cloud cover and test duration. A single N8900APV Solar Array Simulator is designed to test string inverters up to 15 KW. Multiple units can be used to test larger arrays up to 90 KW. The Keysight N8937APV Photovoltaic (PV) Array Simulator enables you to develop, verify and optimize the performance of your inverter maximum power point tracking algorithms.
