The usual approach in testing is to tie the PV inverter to a regenerative grid simulator that provides a four-quadrant, regenerative, grid simulation with advanced features for compliance, safety and product verification testing. Testing PV inverters requires engineers to verify the performance of the inverter's maximum power point tracking (MPPT) algorithms and circuits. MPPT algorithms are complex, and under-the-sun testing at different temperatures and irradiance conditions is difficult, expensive, and time-consuming. In this article, Ainuo will introduce you how to test photovoltaic inverters based on its own product series.
