The core proposition is an Automated Test System (ATS) specifically designed for the comprehensive validation of solar inverter PCBs. This system is engineered to replace manual procedures with a fully automated sequence, from fixture setup to final report generation. 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). Our comprehensive testing solutions ensure the reliability and performance of critical power. While automated test solutions based on platforms like LabVIEW exist, this article presents an alternative architecture developed to leverage existing in-house test equipment, focusing on flexibility, development speed, and seamless integration into a production environment. 1, UL1741, GB/T 19939, NB/T 32004, CGC/GF004/GF035 preliminary test requirements. Power Conversion Systems (PCS) are devices connected between the battery system. 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.
