How do I test a photovoltaic (PV) inverter?

Keysight’s photovoltaic (PV) simulator includes the hardware and software to test a single maximum power point tracking (MPPT) inverter accurately. Test PV voltages up to 2000 V and 60 A with a single supply. DG9000 Series software licenses are available to test string inverter with 4-, 8-, or 12-MPPT channels.

How does a PV inverter test work?

Inductive load simulation is crucial for assessing the inverter's capability to handle dynamic loads, voltage transients, and power factor correction in the presence of inductive loads. Another key component of a PV inverter test system is power grid testing, which evaluates the inverter's ability to interact with the power grid.

Why should you implement automated testing in your EV/PV inverter production?

Implementing automated testing in your EV or PV inverter production allows you to evaluate the performance, reliability, and compliance of inverters, providing you with confidence in the quality of your production.

What is a photovoltaic inverter?

A photovoltaic or PV inverter, converts the direct current (DC) output of a solar cell or array into an alternating current (AC) that can be fed directly into the electrical grid (Grid Tie), used by a local electrical grid (Off-Grid), or both (Hybrid Inverters).

How do you test an electric vehicle inverter?

The testing process may involve assessing the inverter's voltage and frequency regulation capabilities, reactive power control, and power factor correction. The inverter plays a critical role in electric vehicles, converting the battery's direct current (DC) into alternating current (AC) to power the vehicle's electric motor.

How do you test a MPPT inverter?

Make sure to test the inverters according to the industry standards, such as EN50530, which provides a procedure for measuring the efficiency of MPPT. Use an AC / grid emulator to load and test the inverter’s output.
