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. 

PV Inverter Test Solutions

In PV inverter testing, simulation tests and connectivity to the grid play critical roles in evaluating the performance and compliance of the inverters.
From simulating real-world conditions to testing grid connectivity, our solutions cover all the essential aspects of inverter testing. A PV inverter test system typically includes components such as a solar array simulator, load simulators, and grid simulators.
A solar array simulator is a test instrument specifically designed to simulate the output characteristics of a solar photovoltaic (PV) array by generating programmable voltage and current levels that mimic the output of solar panels under different irradiance and temperature conditions.
Load simulators replicate the electrical characteristics and behavior of the actual loads the device will encounter in real-world applications. Two common types of load simulation are resistive load and inductive load simulation. Resistive load simulation involves creating a load that exhibits purely resistive behavior, similar to devices such as heaters, incandescent lights, or resistive heating elements. This type of load places a constant resistance on the inverter, allowing for testing its ability to provide power and maintain stability when connected to resistive loads. On the other hand, inductive load simulation involves creating a load that exhibits inductive behavior, similar to motors, transformers, or inductive lighting. These loads incorporate reactive elements and require the inverter to handle the associated reactive power demands. 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. During power grid testing, various parameters and functionalities of the inverter are evaluated to ensure its seamless integration with the grid. This includes evaluating the inverter's ability to synchronize with the grid's voltage and frequency and its response to changes in grid conditions. The testing process may involve assessing the inverter's voltage and frequency regulation capabilities, reactive power control, and power factor correction.
