This data brief introduces the STEVAL-ISV003V1 microinverter, which is designed to optimize the power production of each single solar panel by means of DC/AC conversion.
The STEVAL-ISV003V1 is a demonstration board designed to optimize power production from single solar panels using DC/AC conversion. It implements an advanced control algorithm within a 32-bit STM32 microcontroller to handle both grid synchronization and Maximum Power Point Tracking (MPPT). The system utilizes a high-frequency isolated DC/DC converter with interleaved current and an optimized full-bridge DC/AC inverter.
The device accepts an input voltage ranging from 18 V to 45 V.
The output voltage ranges from 110 V to 240 V AC at 50/60 Hz.
It uses a perturb and observe (P & O) concept to seek the best operating point of the panel.
