Photovoltaic array simulators test, optimize inverter MPPT algorithms

Test & MeasurementN8937APV and N8957APV photovoltaic array simulators help engineers develop, verify and maximize the performance of inverter maximum power point tracking algorithms and circuits. Products can be used in a laboratory or on a manufacturing line to simulate the output characteristics of a real-world photovoltaic array. Devices are autoranging, single-output, programmable dc power sources that can quickly simulate I-V curve characteristics under different environmental conditions (temperature, irradiance, age, cell technology and more), enabling engineers to quickly and comprehensively test their inverters. Products provide stable output power, built-in voltage and current measurements and autoranging output voltage and current from 500 to 1,500V and 10 to 30A. The autoranging capability makes the units more flexible than traditional rectangular-output power supplies because they expand the power curve to provide more voltage and current combinations. http://www.keysight.com/find/N8937APV
