The Keysight N8937APV is a high-power, autoranging DC power supply designed as a photovoltaic (PV) array simulator for testing solar inverters. It is engineered to develop, verify, and optimize the performance of inverter maximum power point tracking (MPPT) algorithms and inverter efficiency. This unit simulates the output characteristics of a PV array under various environmental conditions, including temperature, irradiance, age, and cell technology, enabling comprehensive testing of solar inverters. The N8937APV offers flexibility with its autoranging output, providing a wide range of voltage and current combinations at full power, unlike traditional power supplies with fixed output characteristics. It can also function as a general-purpose autoranging DC power supply.
