Whether your inverter has one or twelve inputs / MPPTs, Keysight's Photovoltaic / Solar Inverter Test Solution can help you go beyond the test standards to maximize performance and bankability.

Maximize the performance of your inverter

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 explosive growth in the solar power generation industry has increased competition and intensified the need for solar inverter test and measurement solutions. With the PV8900 Series and DG9000A software you can simultaneously control and test from one to twelve PV inverter inputs / MPPTS, enabling you to go beyond the test standards, optimizing your inverters to beat the competition.

To keep solar power at grid parity with competing methods of power generation, performance and power conversion efficiency are increasingly important. Small increments in power production have a dramatic effect on the profitability of solar power generation.

You need to ensure your solar inverters are capable of converting the maximum power that is available from the solar array. Developing and verifying the performance of inverter MPPT algorithms and circuits is challenging. MPPT algorithms are complex, and under-the-sun testing with a comprehensive set of temperature and irradiance conditions is extremely difficult, expensive, and time consuming, if even possible at all.

As inverters increase in power, the size of the test array would become unmanageable. As they increase in number of inputs on a single inverter, the complexity of test changes exponentially. The only practical test method is to use a laboratory test solution that can simulate from one to many real-world solar array strings.

Quickly create, visualize, and execute photovoltaic / solar I-V curves

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).
