A photovoltaic (PV) inverter plays a fundamental role in PV systems that facilitate the conversion of sunlight to electrical energy. It is responsible for changing the DC electricity produced by PV panels into AC electricity compatible with the electricity grid. Different types of PV inverters exist such as string inverters, central inverters, and micro-inverters. In residential and smaller commercial settings, string inverters are most common. Central inverters are used in large-scale solar power plants, while micro-inverters are advantageous for modularity and optimized performance for individual panels. Additional features include system PV performance monitoring and safety measures for the safe and efficient operation of the PV system.
