Experimental Investigation and Power Quality Analysis of Solar Micro-inverter for different Operating Conditions

Abstract

There has been a lot of focus in recent years on finding ways to incorporate renewable energy systems, especially solar photovoltaic (PV) systems, into the existing electrical grid. Power conversion technologies that are both efficient and reliable are in high demand due to the expanding popularity of solar photovoltaic (PV) systems. Micro-inverters, which are module-based inverters placed on individual PV modules, have grown in popularity in recent years due to their decentralized design. However, the integration of solar micro-inverter into the electrical grid presents power quality challenges. This research article presents an experimental investigation and power quality analysis of a solar micro-inverter under various operating conditions such as dust and shade.
