A microcontroller-based solar inverter is a system that converts the direct current (DC) produced by solar panels into alternating current (AC), which can be used to power electrical devices. The microcontroller serves as the central control unit, managing the inverter’s functions and ensuring optimal performance.
Solar Panels: Convert sunlight into DC electricity.
Microcontroller: The heart of the system, it manages the inverter’s operations, including monitoring the input from the solar panels and controlling the power conversion process.
Inverter Circuit: Converts DC to AC using power electronic components like MOSFETs or IGBTs (Insulated-Gate Bipolar Transistors).
DC-AC Converter: Converts the DC power from solar panels into AC power, which is then supplied to the electrical grid or load.
Filter: Smooths the AC waveform to reduce harmonics and provide a stable output.
Battery (optional): Some systems include a battery to store excess power for use during cloudy days or at night.
Display or Communication Interface: Provides monitoring of system performance, such as energy output and fault conditions.
A microcontroller-based solar inverter is a key component in solar power systems, offering efficient DC to AC conversion, real-time monitoring, and optimization of energy usage. It plays an important role in residential, commercial, and off-grid solar installations, contributing to sustainable and clean energy solutions.
