The Keysight PV8921A Photovoltaic Array Simulator is a powerful and flexible tester specifically designed for solar inverter development and testing. Part of the PV8900 series, this model features accurate simulation of photovoltaic array I-V curves, allowing designers to optimize the performance and efficiency of maximum power point tracking (MPPT) algorithms.
The PV8921A is optimized for applications requiring a maximum output power of 20 kW and a current of 30 A. Its autoranging functionality and compact size make it ideal for medium-sized test environments.
Product features of the PV8921A:
Powerful simulation: The PV8921A enables realistic simulation of the output characteristics of solar systems under different environmental conditions (e.g. temperature, irradiation). This facilitates the precise testing of MPPT algorithms.
Autoranging function: The autoranging output characteristic offers maximum flexibility by supporting a variety of voltage and current combinations at full power. This reduces the need for multiple power supply units.
Compact design: The device is designed in a compact 3U height and delivers a maximum output of 20 kW. This saves valuable space in the test laboratory.
Easy scalability: Multiple units can be connected in parallel to achieve an output of up to 600 kW. This is ideal for testing powerful solar inverters.
Integrated protection functions: The PV8921A offers overcurrent, overvoltage and overtemperature protection to protect connected devices.
