The Keysight N8937APV is a programmable photovoltaic array simulator engineered to emulate I-V curve characteristics of solar arrays under variable environmental conditions. This single-output, autoranging DC power supply delivers up to 1500 VDC at 30 A (15 kW) and enables development, verification, and optimization of solar inverter MPPT algorithms without field testing. The N8937APV operates in Curve Mode or Table Mode with up to 1024 programmable points, supporting simulation of temperature, irradiance, age, and cell technology variables.
