If you are designing or manufacturing photovoltaic solar inverters from one to twelve inputs and up to 2000 V per input, Keysight’s Photovoltaic / Solar Inverter Test Solution can help you develop, verify, and maximize the performance and bankability of your inverter. The solution enables you to optimize maximum power point tracking (MPPT) algorithms and circuits. With the DG8900 software you can quickly and easily test individual inputs to the European EN50530 (April 2010) standard to easily compare your results to your competitors.

The Keysight PV8921A Photovoltaic (PV) Array Simulator enables you to develop, verify and optimize the performance of your inverter maximum power point tracking algorithms. Developing and verifying the performance of inverter maximum power point tracking (MPPT) algorithms is challenging. MPPT algorithms are complex, and under-the-sun testing with a comprehensive set of temperature and irradiance conditions is difficult, expensive and time consuming.

Use the Keysight PV8921A Photovoltaic Array Simulators in your design laboratory or on your manufacturing line to simulate the output characteristics of a real-world photovoltaic array. The PV8921A PV array simulator is an autoranging, programmable DC power source that can quickly simulate I-V curve characteristics under different environmental conditions (temperature, irradiance, age, cell technology and more), enabling you to quickly and comprehensively test your solar inverters.

Keysight’s PV simulation solution consists of the PV8900A Series PV simulator hardware and two software packages to choose from: the DG8900 SAS control/curve generation software and the DG9000 advance/multi-input PV inverter test software.

The PV simulators are autoranging, programmable DC power sources that simulate the output characteristics of a photovoltaic array under different environmental conditions (temperature, irradiance, age, cell technology, etc.) enabling you to quickly and comprehensively test inverter MPPT algorithms and inverter efficiency.

The DG8900 SAS Control software allows the user to control one PV8900A (or one primary/secondary set) output as well as easily create, visualize, and download solar / photovoltaic I-V curves to the instrument using the Curve Workspace. Once a curve has been downloaded to an PV8900A, the user can enable the output and watch as their PV inverter searches for the maximum power point, gaining insight into their MPPT algorithm. The DG9000 software allows the user to control the output of from one to twelve PV8900A units (or primary/secondary combinations).
